useragent online lookup

Sometimes when we check the Nginx and Apache logs of the server, we often see some strange UserAgent, we need to parse these UserAgents to see if they are normal users.

For example, the following is a more complex UserAgent:

Mozilla/5.0 (Linux; Android 10; SAMSUNG SM-A022F Build/QP1A.190711.020; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 SamsungBrowser/7.4 Chrome/92.0.4515.159 Mobile Safari/537.36

We can read the following useful information without using any tools:

• This is a Samsung Phone websitep>

• Mobile's operating system is Android 10

• This is a Samsung Mobile BrowserThe website visited, its version is: 7.4

Through the above UserAgent, we can only read this information, but there are still some information that cannot be read out, such as the model of the mobile phone, the rendering engine of the browser, etc. We don't know the information.

When encountering these problems, we can use the useragent online search tool, which can be easily answeredour question.

By accessing the useragent online search tool, we directly enter your UserAgent above, click the crawler query, and the result will appear. By parsing the result, we can see that this is a Samsung - Galaxy A02 phone, then we click Samsung Browser, you can see its more detailed information, through the results we can see that its rendering engine is WebKit/Blink.

Is it the perfect answer to our question.

Useragent online search can also easily identify crawler information. For example, the following Useragent is a crawler, let's check it out:

CriteoBot/0.1 (+https://www.criteo.com/criteo-crawler/)

The screenshot of the query results is as follows:

By querying, we can see that this is a crawler and has been identified, and the classification of the crawler is Marketing crawler, the crawler name is: CriteoBot, we click on the crawler name, you can also see more information: the company to which the crawler belongs, the crawler documentation, the crawler description, the different UserAgents of the crawler, the crawler's collection time, the crawler's IP address segment, etc. It can be said that all aspects of the crawler have been shown in front of us.

At the same time, the useragent online search tool can also query some app clients, mail clients, libraries, etc., which is very convenient.

Summary

Mainly introduces the specific usage of the useragent online search tool, and also an example shows that the useragent online search tool can query the information of the useragent, which can help us check some Crawler information.
