1、 Redirect

moco Can help us simulate redirection , Redirect the request to a different one url, You can simulate some request interception 、 Failure of request verification, etc .

One 、 Redirect to Baidu

1、 establish 09Redirect.json The configuration file .

redirectTo： Redirect the request to the specified url On .

The contents are as follows ：

[
    {
        "description":" Redirect to Baidu ",
        "request":{
            "uri":"/redirect"
        },
        "redirectTo":"https://www.baidu.com/"
    }
]

Copy

2、 Input start moco The service command .

java -jar moco-runner-0.12.0-standalone.jar http -p 8083 -c 09Redirect.json

3、 Browser access moco Service address .

Access address ：http://localhost:8083/redirect

The access results show ： visit http://localhost:8083/redirect Jump to https://www.baidu.com/ page .

Two 、 Redirect to custom web pages

1、 establish 10Redirect2.json The configuration file .

The configuration file has 2 Interface （ Redirecting Requests 、 Request redirected to ）.

redirectTo： Redirect the request to the specified url On .

The contents are as follows ：

[
    {
        "description":" Redirect to custom web pages ",
        "request":{
            "uri":"/redirect/topath"
        },
        "redirectTo":"/redirect/new"
    },
    {
        "description":" Request redirected to ",
        "request":{
            "uri":"/redirect/new"
        },
        "response":{
            "headers":{
                "Content-Type":"text/html;charset=gbk"
            },
            "text":" Redirection succeeded "
        }
    }
]

Copy

2、 Input start moco The service command .

The access results show ：

visit http://localhost:8083/redirect/topath Jump to http://localhost:8083/redirect/new page .

2、 Regular expressions

1、 establish 11Match.json The configuration file .

match： Regular expressions .

\\w Match the letter 、 Numbers 、 Underlined characters .

* Represents any number of characters .

\\w* Denotes any number of \\w

The contents are as follows ：

[
    {
        "description":" Regular expressions ",
        "request":{
            "uri":{
                "match": "/\\w*/demo"
            }
        },
        "response":{
            "text": "Moco Match"
        }
    }
]

Copy

2、 Input start moco The service command .

java -jar moco-runner-0.12.0-standalone.jar http -p 8083 -c 11Match.json

3、 Browser access moco Service address .

Because the request address uses regular expressions , The following addresses can be accessed ：

http://localhost:8083/123/demo

http://localhost:8083/abc/demo

http://localhost:8083/123abc/demo

The access results show ：

moco By Java Regular expression implementation , You can see more details here .

https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html

3、 Delay

Sometimes , We need a delay to simulate slow server-side operations .

1、 establish 12Latency.json The configuration file .

latency： Delay . For example, set delay 5 second ：

"latency":{
"duration": 5,
"unit": "second"
}

Copy

The contents are as follows ：

[
    {
        "description":" Delay ",
        "request":{
            "uri":"/demo",
            "method":"get"
        },
        "response":{
            "latency":{
            "duration": 5,
            "unit": "second"
        },
            "text":"Moco Latency"
        }
    }
]

Copy

2、 Input start moco The service command .

java -jar moco-runner-0.12.0-standalone.jar http -p 8083 -c 12Latency.json

3、 Browser access moco Service address .

Access address ：http://localhost:8083/demo

The access results show ： Delay 5 Seconds later , Return the response content .

4、 Templates

Sometimes , We need to customize our response based on some content , For example, the response should have the same header as the request . This can be achieved through templates ： You can use... In templates req Get request information .

Method ：

"template": "${req.version}"
"template": "${req.method}"
"template": "${req.content}"
"template": "${req.headers['foo']}"
"template": "${req.queries['foo']}"
"template": "${req.forms['foo']}"
"template": "${req.cookies['foo']}"
"template": "${req.json.foo}"

Copy

1、 establish 13Template.json The configuration file .

template： Templates .

for example ： Get the request parameter field value in the response content .

"template": "${req.queries['username']}"

The contents are as follows ：

[
    {
        "description":" Templates ",
        "request":{
            "uri":"/demo",
            "method":"get"
        },
        "response":{
            "text": {
                "template": "${req.queries['username']}"
            }
        }
    }
]

3、 Browser access moco Service address .

Access address ：http://localhost:8083/demo?username=admin

The access results show ： Response content to get request parameters username Value （admin）.

5、 event

5.1、 The whole event

Sometimes , When we request some specific interfaces , You may need to ask for another address , In order to complete the request .

The complete event will be triggered after your request is fully processed .

One 、Get request

1、 establish 14Complete.json The configuration file .

The contents are as follows ：

[
    {
        "description":" The whole event （Get request ）",
        "request":{
            "uri":"/event",
            "method":"get"
        },
        "response": {
            "text": "event"
        },
        "on": {
            "complete": {
                "get" : {
                    "url":"https://www.baidu.com/"
                }
            }
        }
    }
]

    {
        "description":" The whole event （Post request ）",
        "request":{
            "uri":"/event",
            "method":"get"
        },
        "response":{
            "text":"event"
        },

3、 Browser access moco Service address .

Access address ：http://localhost:8083/event

The access results show ：

5.2、 Asynchronous events

The previous requests are synchronized by default , This means that it will not be returned to the client until the server finishes processing . Of course, you can also make asynchronous requests , You can also specify the waiting time for this asynchronous request .

1、 establish 16Asynchronous.json The configuration file .

"async":"true" Start asynchronous request .

"latency":5000 Set the waiting time for this asynchronous request .

The contents are as follows ：

[
    {
        "description":" Asynchronous events ",
        "request":{
            "uri":"/event",
            "method":"get"
        },
        "response":{
            "text":"event"
        },
        "on":{
            "complete":{
                "async":"true",
                "latency":5000,
                "post":{
                    "url":"https://www.baidu.com/",
                    "content":"content"
                }
            }
        }
    }
]

Copy

2、 Input start moco The service command .

java -jar moco-runner-0.12.0-standalone.jar http -p 8083 -c 16Asynchronous.json

3、 Browser access moco Service address .

Access address ：http://localhost:8083/event

The access results show ：

6、 Modular design

In practice , Each business module has its own business （ A lot of requests ）, If these different business modules are written in a configuration file , Obviously, it's not very easy to manage . Here we use the idea of sub module design to solve this problem .

1、 create profile .

As shown in the figure ：

Global.json For global profiles （ Appoint A Business module 、B Business module ）,moco Support the introduction of other configuration files in the global configuration file , In this way, the configuration file can be defined according to different businesses , Easy to manage .

A.json by A Business module configuration file .

B.json by B Business module configuration file .

Global.json The contents are as follows ：

[
    { "context":"/a", "include":"A.json" },
    { "context":"/b", "include":"B.json" }
]

Copy

A.json The contents are as follows ：

[
    {
        "description":" modular A",
        "request":{
            "uri":"/demoa"
        },
        "response":{
            "text":"A Module"
        }
    }
]

Copy

B.json The contents are as follows ：

[
    {
        "description":" modular B",
        "request":{
            "uri":"/demob"
        },
        "response":{
            "text":"B Module"
        }
    }
]

Copy

2、 Input start moco The service command .

java -jar moco-runner-0.12.0-standalone.jar http -p 8083 -g Global.json

Be careful , At this time, you need to pass the parameter -g To load the global configuration file , Instead of using -c.

3、 Browser access moco Service address .

（1） visit A Business module

Access address ：http://localhost:8083/a/demoa

The access results show ：

（2） visit B Business module

Access address ：http://localhost:8083/b/demob

The access results show ：
