A next generation HTTP client for Python. 🦋

0.23.3 (4th Jan, 2023)

Fixed

• Version 0.23.2 accidentally included stricter type checking on query parameters. This shouldn've have been included in a minor version bump, and is now reverted. (#2523, #2539)

0.23.2 (2nd Jan, 2023)

Added

• Support digest auth nonce counting to avoid multiple auth requests. (#2463)

Fixed

• Multipart file uploads where the file length cannot be determine now use chunked transfer encoding, rather than loading the entire file into memory in order to determine the Content-Length. (#2382)
• Raise TypeError if content is passed a dict-instance. (#2495)
• Partially revert the API breaking change in 0.23.1, which removed RawURL. We continue to expose a url.raw property which is now a plain named-tuple. This API is still expected to be deprecated, but we will do so with a major version bump. (#2481)

0.23.1

Added

• Support for Python 3.11. (#2420)
• Allow setting an explicit multipart boundary in Content-Type header. (#2278)
• Allow tuple or list for multipart values, not just list. (#2355)
• Allow str content for multipart upload files. (#2400)
• Support connection upgrades. See https://www.encode.io/httpcore/extensions/#upgrade-requests

Fixed

• Don't drop empty query parameters. (#2354)

Removed

• Drop .read/.aread from SyncByteStream/AsyncByteStream (#2407)
• Drop RawURL. (#2241)

0.23.0 (23rd May, 2022)

Changed

• Drop support for Python 3.6. (#2097)
• Use utf-8 as the default character set, instead of falling back to charset-normalizer for auto-detection. To enable automatic character set detection, see the documentation. (#2165)

Fixed

• Fix URL.copy_with for some oddly formed URL cases. (#2185)
• Digest authentication should use case-insensitive comparison for determining which algorithm is being used. (#2204)
• Fix console markup escaping in command line client. (#1866)
• When files are used in multipart upload, ensure we always seek to the start of the file. (#2065)
• Ensure that iter_bytes never yields zero-length chunks. (#2068)
• Preserve Authorization header for redirects that are to the same origin, but are an http-to-https upgrade. (#2074)
• When responses have binary output, don't print the output to the console in the command line client. Use output like <16086 bytes of binary data> instead. (#2076)
• Fix display of --proxies argument in the command line client help. (#2125)
• Close responses when task cancellations occur during stream reading. (#2156)
• Fix type error on accessing .request on HTTPError exceptions. (#2158)

0.22.0 (26th January, 2022)

Added

• Support for the SOCKS5 proxy protocol via the socksio package. (#2034)
• Support for custom headers in multipart/form-data requests (#1936)

Fixed

• Don't perform unreliable close/warning on __del__ with unclosed clients. (#2026)
• Fix Headers.update(...) to correctly handle repeated headers (#2038)

0.21.3 (6th January, 2022)

Fixed

• Fix streaming uploads using SyncByteStream or AsyncByteStream. Regression in 0.21.2. (#2016)

0.21.2 (5th January, 2022)

Fixed

• HTTP/2 support for tunnelled proxy cases. (#2009)
• Improved the speed of large file uploads. (#1948)

0.21.1 (16th November, 2021)

Fixed

• The response.url property is now correctly annotated as URL, instead of Optional[URL]. (#1940)

0.21.0 (15th November, 2021)

The 0.21.0 release integrates against a newly redesigned httpcore backend.

Both packages ought to automatically update to the required versions, but if you are seeing any issues, you should ensure that you have httpx==0.21.* and httpcore==0.14.* installed.

Added

• The command-line client will now display connection information when -v/--verbose is used.
• The command-line client will now display server certificate information when -v/--verbose is used.
• The command-line client is now able to properly detect if the outgoing request should be formatted as HTTP/1.1 or HTTP/2, based on the result of the HTTP/2 negotiation.

0.20.0 (13th October, 2021)

The 0.20.0 release adds an integrated command-line client, and also includes some design changes. The most notable of these is that redirect responses are no longer automatically followed, unless specifically requested.

This design decision prioritises a more explicit approach to redirects, in order to avoid code that unintentionally issues multiple requests as a result of misconfigured URLs.

For example, previously a client configured to send requests to http://api.github.com/ would end up sending every API request twice, as each request would be redirected to https://api.github.com/.

If you do want auto-redirect behaviour, you can enable this either by configuring the client instance with Client(follow_redirects=True), or on a per-request basis, with .get(..., follow_redirects=True).

This change is a classic trade-off between convenience and precision, with no "right" answer. See discussion #1785 for more context.

The other major design change is an update to the Transport API, which is the low-level interface against which requests are sent. Previously this interface used only primitive datastructures, like so...

(status_code, headers, stream, extensions) = transport.handle_request(method, url, headers, stream, extensions)
try
    ...
finally:
    stream.close()

Now the interface is much simpler...

response = transport.handle_request(request)
try
    ...
finally:
    response.close()

Changed

• The allow_redirects flag is now follow_redirects and defaults to False.
• The raise_for_status() method will now raise an exception for any responses except those with 2xx status codes. Previously only 4xx and 5xx status codes would result in an exception.
• The low-level transport API changes to the much simpler response = transport.handle_request(request).
• The client.send() method no longer accepts a timeout=... argument, but the client.build_request() does. This required by the signature change of the Transport API. The request timeout configuration is now stored on the request instance, as request.extensions['timeout'].

Added

• Added the httpx command-line client.
• Response instances now include .is_informational, .is_success, .is_redirect, .is_client_error, and .is_server_error properties for checking 1xx, 2xx, 3xx, 4xx, and 5xx response types. Note that the behaviour of .is_redirect is slightly different in that it now returns True for all 3xx responses, in order to allow for a consistent set of properties onto the different HTTP status code types. The response.has_redirect_location location may be used to determine responses with properly formed URL redirects.

Fixed

• response.iter_bytes() no longer raises a ValueError when called on a response with no content. (Pull #1827)
• The 'wsgi.error' configuration now defaults to sys.stderr, and is corrected to be a TextIO interface, not a BytesIO interface. Additionally, the WSGITransport now accepts a wsgi_error confguration. (Pull #1828)
• Follow the WSGI spec by properly closing the iterable returned by the application. (Pull #1830)

1.0.0.beta0 (14th September 2021)

Fixed

• Clean up some cases where warnings were being issued. (Pull #1687)

0.18.1 (29th April, 2021)

Changed

• Update brotli support to use the brotlicffi package (Pull #1605)
• Ensure that Request(..., stream=...) does not auto-generate any headers on the request instance. (Pull #1607)

Fixed

• Pass through timeout=... in top-level httpx.stream() function. (Pull #1613)
• Map httpcore transport close exceptions to httpx exceptions. (Pull #1606)

0.18.0 (27th April, 2021)

The 0.18.x release series formalises our low-level Transport API, introducing the base classes httpx.BaseTransport and httpx.AsyncBaseTransport.

See the "Writing custom transports" documentation and the httpx.BaseTransport.handle_request() docstring for more complete details on implementing custom transports.

Pull request #1522 includes a checklist of differences from the previous httpcore transport API, for developers implementing custom transports.

The following API changes have been issuing deprecation warnings since 0.17.0 onwards, and are now fully deprecated...

• You should now use httpx.codes consistently instead of httpx.StatusCodes.
• Use limits=... instead of pool_limits=....
• Use proxies={"http://": ...} instead of proxies={"http": ...} for scheme-specific mounting.

Changed

• Transport instances now inherit from httpx.BaseTransport or httpx.AsyncBaseTransport, and should implement either the handle_request method or handle_async_request method. (Pull #1522, #1550)
• The response.ext property and Response(ext=...) argument are now named extensions. (Pull #1522)
• The recommendation to not use data=<bytes|str|bytes (a)iterator> in favour of content=<bytes|str|bytes (a)iterator> has now been escalated to a deprecation warning. (Pull #1573)
• Drop Response(on_close=...) from API, since it was a bit of leaking implementation detail. (Pull #1572)
• When using a client instance, cookies should always be set on the client, rather than on a per-request basis. We prefer enforcing a stricter API here because it provides clearer expectations around cookie persistence, particularly when redirects occur. (Pull #1574)
• The runtime exception httpx.ResponseClosed is now named httpx.StreamClosed. (#1584)
• The httpx.QueryParams model now presents an immutable interface. The is a discussion on the design and motivation here. Use client.params = client.params.merge(...) instead of client.params.update(...). The basic query manipulation methods are query.set(...), query.add(...), and query.remove(). (#1600)

Added

• The Request and Response classes can now be serialized using pickle. (#1579)
• Handle data={"key": [None|int|float|bool]} cases. (Pull #1539)
• Support httpx.URL(**kwargs), for example httpx.URL(scheme="https", host="www.example.com", path="/'), or httpx.URL("https://www.example.com/", username="[email protected]", password="123 456"). (Pull #1601)
• Support url.copy_with(params=...). (Pull #1601)
• Add url.params parameter, returning an immutable QueryParams instance. (Pull #1601)
• Support query manipulation methods on the URL class. These are url.copy_set_param(), url.copy_add_param(), url.copy_remove_param(), url.copy_merge_params(). (Pull #1601)
• The httpx.URL class now performs port normalization, so :80 ports are stripped from http URLs and :443 ports are stripped from https URLs. (Pull #1603)
• The URL.host property returns unicode strings for internationalized domain names. The URL.raw_host property returns byte strings with IDNA escaping applied. (Pull #1590)

Fixed

• Fix Content-Length for cases of files=... where unicode string is used as the file content. (Pull #1537)
• Fix some cases of merging relative URLs against Client(base_url=...). (Pull #1532)
• The request.content attribute is now always available except for streaming content, which requires an explicit .read(). (Pull #1583)

0.17.1

Fixed

• Type annotation on CertTypes allows keyfile and password to be optional. (Pull #1503)
• Fix httpcore pinned version. (Pull #1495)

0.17.0

Added

• Add httpx.MockTransport(), allowing to mock out a transport using pre-determined responses. (Pull #1401, Pull #1449)
• Add httpx.HTTPTransport() and httpx.AsyncHTTPTransport() default transports. (Pull #1399)
• Add mount API support, using httpx.Client(mounts=...). (Pull #1362)
• Add chunk_size parameter to iter_raw(), iter_bytes(), iter_text(). (Pull #1277)
• Add keepalive_expiry parameter to httpx.Limits() configuration. (Pull #1398)
• Add repr to httpx.Cookies to display available cookies. (Pull #1411)
• Add support for params=<tuple> (previously only params=<list> was supported). (Pull #1426)

Fixed

• Add missing raw_path to ASGI scope. (Pull #1357)
• Tweak create_ssl_context defaults to use trust_env=True. (Pull #1447)
• Properly URL-escape WSGI PATH_INFO. (Pull #1391)
• Properly set default ports in WSGI transport. (Pull #1469)
• Properly encode slashes when using base_url. (Pull #1407)

0.16.1 (October 8th, 2020)

Fixed

• Support literal IPv6 addresses in URLs. (Pull #1349)
• Force lowercase headers in ASGI scope dictionaries. (Pull #1351)

0.16.0 (October 6th, 2020)

Changed

• Preserve HTTP header casing. (Pull #1338, encode/httpcore#216, python-hyper/h11#104)
• Drop response.next() and response.anext() methods in favour of response.next_request attribute. (Pull #1339)
• Closed clients now raise a runtime error if attempting to send a request. (Pull #1346)

Added

Added

• Add response.next_request (Pull ##1334)

0.15.4 (September 25th, 2020)

Added

• Support direct comparisons between Headers and dicts or lists of two-tuples. Eg. assert response.headers == {"Content-Length": 24} (Pull #1326)

Fixed

0.15.3 (September 24th, 2020)

Fixed

• Fixed connection leak in async client due to improper closing of response streams. (Pull #1316)

0.15.2 (September 23nd, 2020)

Fixed

• Fixed response.elapsed property. (Pull #1313)
• Fixed client authentication interaction with .stream(). (Pull #1312)

0.15.1 (September 23nd, 2020)

Fixed

• ASGITransport now properly applies URL decoding to the path component, as-per the ASGI spec. (Pull #1307)

0.15.0 (22nd September 2020)

Added

• Added support for curio. (Pull https://github.com/encode/httpcore/pull/168)

• Added Request(content=...) for byte content, instead of overloading Request(data=...) (Pull #1266)
• Added support for all URL components as parameter names when using url.copy_with(...). (Pull #1285)
• Neater split between automatically populated headers on Request instances, vs default client.headers. (Pull #1248)
• Unclosed AsyncClient instances will now raise warnings if garbage collected. (Pull #1197)
• Support Response(content=..., text=..., html=..., json=...) for creating usable response instances in code. (Pull #1265, #1297)
• Support instantiating requests from the low-level transport API. (Pull #1293)
• Raise errors on invalid URL types. (Pull #1259)

Changed

• Cleaned up expected behaviour for URL escaping. url.path is now URL escaped. (Pull #1285)
• Cleaned up expected behaviour for bytes vs str in URL components. url.userinfo and url.query are not URL escaped, and so return bytes. (Pull #1285)
• Drop url.authority property in favour of url.netloc, since "authority" was semantically incorrect. (Pull #1285)
• Drop url.full_path property in favour of url.raw_path, for better consistency with other parts of the API. (Pull #1285)
• No longer use the chardet library for auto-detecting charsets, instead defaulting to a simpler approach when no charset is specified. (#1269)

Fixed

• Swapped ordering of redirects and authentication flow. (Pull #1267)
• .netrc lookups should use host, not host+port. (Pull #1298)

Removed

• The URLLib3Transport class no longer exists. We've published it instead as an example of a custom transport class. (Pull #1182)
• Drop request.timer attribute, which was being used internally to set response.elapsed. (Pull #1249)
• Drop response.decoder attribute, which was being used internally. (Pull #1276)
• Request.prepare() is now a private method. (Pull #1284)

0.14.3 (September 2nd, 2020)

Added

• http.Response() may now be instantiated without a request=... parameter. Useful for some unit testing cases. (Pull #1238)
• Add 103 Early Hints and 425 Too Early status codes. (Pull #1244)

Fixed

• DigestAuth now handles responses that include multiple 'WWW-Authenticate' headers. (Pull #1240)
• Call into transport __enter__/__exit__ or __aenter__/__aexit__ when client is used in a context manager style. (Pull #1218)

0.14.2 (August 24th, 2020)

Added

• Support client.get(..., auth=None) to bypass the default authentication on a clients. (Pull #1115)
• Support client.auth = ... property setter. (Pull #1185)
• Support httpx.get(..., proxies=...) on top-level request functions. (Pull #1198)
• Display instances with nicer import styles. (Eg. <httpx.ReadTimeout ...>) (Pull #1155)
• Support cookies=[(key, value)] list-of-two-tuples style usage. (Pull #1211)

Fixed

• Ensure that automatically included headers on a request may be modified. (Pull #1205)
• Allow explicit Content-Length header on streaming requests. (Pull #1170)
• Handle URL quoted usernames and passwords properly. (Pull #1159)
• Use more consistent default for HEAD requests, setting allow_redirects=True. (Pull #1183)
• If a transport error occurs while streaming the response, raise an httpx exception, not the underlying httpcore exception. (Pull #1190)
• Include the underlying httpcore traceback, when transport exceptions occur. (Pull #1199)

0.14.1 (August 11th, 2020)

Added

• The httpx.URL(...) class now raises httpx.InvalidURL on invalid URLs, rather than exposing the underlying rfc3986 exception. If a redirect response includes an invalid 'Location' header, then a RemoteProtocolError exception is raised, which will be associated with the request that caused it. (Pull #1163)

Fixed

• Handling multiple Set-Cookie headers became broken in the 0.14.0 release, and is now resolved. (Pull #1156)

0.14.0 (August 7th, 2020)

The 0.14 release includes a range of improvements to the public API, intended on preparing for our upcoming 1.0 release.

• Our HTTP/2 support is now fully optional. You now need to use pip install httpx[http2] if you want to include the HTTP/2 dependancies.
• Our HSTS support has now been removed. Rewriting URLs from http to https if the host is on the HSTS list can be beneficial in avoiding roundtrips to incorrectly formed URLs, but on balance we've decided to remove this feature, on the principle of least surprise. Most programmatic clients do not include HSTS support, and for now we're opting to remove our support for it.
• Our exception hierarchy has been overhauled. Most users will want to stick with their existing httpx.HTTPError usage, but we've got a clearer overall structure now. See https://www.python-httpx.org/exceptions/ for more details.

When upgrading you should be aware of the following public API changes. Note that deprecated usages will currently continue to function, but will issue warnings.

• You should now use httpx.codes consistently in favour of httpx.StatusCodes.
• Usage of httpx.Timeout() should now always include an explicit default. Eg. httpx.Timeout(None, pool=5.0).
• When using httpx.Timeout(), we now have more concisely named keyword arguments. Eg. read=5.0, instead of read_timeout=5.0.
• Use httpx.Limits() instead of httpx.PoolLimits(), and limits=... instead of pool_limits=....
• The httpx.Limits(max_keepalive=...) argument is now deprecated in favour of a more explicit httpx.Limits(max_keepalive_connections=...)
• Keys used with Client(proxies={...}) should now be in the style of {"http://": ...}, rather than {"http": ...}.
• The multidict methods Headers.getlist() and QueryParams.getlist() are deprecated in favour of more consistent .get_list() variants.
• The URL.is_ssl property is deprecated in favour of URL.scheme == "https".
• The URL.join(relative_url=...) method is now URL.join(url=...). This change does not support warnings for the deprecated usage style.

One notable aspect of the 0.14.0 release is that it tightens up the public API for httpx, by ensuring that several internal attributes and methods have now become strictly private.

The following previously had nominally public names on the client, but were all undocumented and intended solely for internal usage. They are all now replaced with underscored names, and should not be relied on or accessed.

These changes should not affect users who have been working from the httpx documentation.

• .merge_url(), .merge_headers(), .merge_cookies(), .merge_queryparams()
• .build_auth(), .build_redirect_request()
• .redirect_method(), .redirect_url(), .redirect_headers(), .redirect_stream()
• .send_handling_redirects(), .send_handling_auth(), .send_single_request()
• .init_transport(), .init_proxy_transport()
• .proxies, .transport, .netrc, .get_proxy_map()

See pull requests #997, #1065, #1071.

Some areas of API which were already on the deprecation path, and were raising warnings or errors in 0.13.x have now been escalated to being fully removed.

• Drop ASGIDispatch, WSGIDispatch, which have been replaced by ASGITransport, WSGITransport.
• Drop dispatch=...`` on client, which has been replaced bytransport=...``
• Drop soft_limit, hard_limit, which have been replaced by max_keepalive and max_connections.
• Drop Response.stream andResponse.raw, which have been replaced by ``.aiter_bytes and .aiter_raw.
• Drop proxies=<transport instance> in favor of proxies=httpx.Proxy(...).

See pull requests #1057, #1058.
