Browser User-Agent example analysis, in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

1. Basic knowledge:

User-Agent of Http Header

User Agent, which is called user agent in Chinese, is a part of Http protocol and a part of header domain. User Agent is also referred to as UA. It is a special string header, is a kind of access to the website to provide you with the browser type and version, operating system and version, browser kernel, and other information. Through this logo, the websites visited by users can display different typesetting to provide users with a better experience or do information statistics; for example, mobile access to Google is not the same as computer access, which is judged by Google based on the UA of visitors. UA can be camouflaged.

The standard format of the browser's UA string: browser ID (operating system ID; encryption level ID; browser language) rendering engine ID version information. But each browser is different.

String description:

1. Browser logo

For compatibility and promotion purposes, many browsers have the same logo, so the browser logo does not indicate the true version of the browser, and the real version information can be found at the end of the UA string.

2. Operating system identification

3. Encryption level identification

N: indicates no secure encryption

I: indicates weak security encryption

U: indicates strong security encryption

4. Browser language

The language specified in preferences > General > language

5. Rendering engine

The mainstream rendering engines used by display browsers are: Gecko, WebKit, KHTML, Presto, Trident, Tasman, etc., in the format of: rendering engine / version information

6. Version information

Displays the real version information of the browser in the format: browser / version information

Note:

1. In the setting of advertising orientation, both browser orientation and operating system orientation are directed against the information in User-Agent.

2. For more User-Agent information, please refer to the history of User-agent strings

Second, browser identification

1. IE browser (take IE 9.0 as an example)

PC side: User-Agent:Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)

Mobile devices: User-Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows Phone OS 7.5; Trident/5.0; IEMobile/9.0; HTC; Titan)

Since roaming, window of the World, 360 browsers, Tencent browsers and Sogou browsers, Avant and Green Browser all use the kernel of IE, the standard of IE browser judgment is the "MSIE" field, and the number after the MSIE field is the version number. But at the same time, it also needs to decide that it does not include "Maxthon", "The world", "360SE", "TencentTraveler", "SE", "Avant" and other fields (Green Browser is not clearly identified). Mobile devices also need to determine the IEMobile+ version number.

2. 360 browser

PC side: User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; InfoPath.2; .NET 4.0C; .NET 4.0E; .NET CLR 2.0.50727; 360SE)

Mobile device: none for now

The standard of the browser is the "360SE" field, and there is no version to indicate it.

3. Sogou browser

PC side: User-Agent:Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; SE 2.x MetaSr 1.0; SE 2.x MetaSr 1.0; .NET CLR 2.0.50727; SE 2.x MetaSr 1.0)

The judging criteria of Sogou browser are "SE" and "MetaSr" fields, and the version number is the number after SE.

4 、 Chrome

Mobile device: User-Agent: Mozilla/5.0 (Linux; U; Android 2.2.1; zh-cn; HTC_Wildfire_A3333 Build/FRG83D) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

The chrome browser on the PC side is judged by the chrome field, and the number after the chrome is the version number; the chrome browser on the mobile side judges the "android", "linux", "mobile safari" and other fields, and the number after the version is the version number.

5 、 Safari

Because Chrome and Nokia's Series 60 browser also use WebKit kernel, the judgment of Safari browser must be: include safari field, do not contain chrome and other information, and the number after "version/" is the version number. The one that contains the Mobile field under the above conditions is the Safari browser on the mobile device.
