Enterprise number obtains user information and user information

One of the most basic functions of business operations is to obtain the identity of a visitor. The traditional acquisition method is to provide a logon page for a visitor to log on.

When a user accesses a page in the enterprise number, he or she can obtain the account information of the user based on relevant APIs to match the user information stored on the Business Server.

1. Introduction 1.1

To put it bluntly, Enterprise web development is mobile web development. The special point is how to obtain user identity information.

To obtain user information, follow these steps:

When you access a service page, you can obtain the user information through the OAuth interface → get userId Based on code → get information based on userId.

 

1.2 detailed process ① get code

API: Http://qydev.weixin.qq.com/wiki/index.php? Title = OAuth % E9 % AA % 8C % E8 % AF % 81% E6 % 8E % A5 % E5 % 8F % A3 #. E4.BC. 81. E4.B8.9A. E8.8E. B7.E5.8F. 96 code

Description: After the webpage passes OAuth2.0 verification, it is redirected to the original webpage and added code information after the url.

For example: Http://akmsg.com/a.html => OAhth2.0 => http://akmsg.com/a.html? Code = CODE & state = STATE

② Obtain userId Based on code

API: Http://qydev.weixin.qq.com/wiki/index.php? Title = OAuth % E9 % AA % 8C % E8 % AF % 81% E6 % 8E % A5 % E5 % 8F % A3 #. e6.A0. b9.E6.8D. AEcode. e8.8E. b7.E5.8F. 96. e6.88.90.E5.91.98. e4.BF. a1.E6.81. AF

Description: After you call this interface, you will get the userId. Note: userId is the encrypted account.

③ Obtain information based on userId

API: Http://qydev.weixin.qq.com/wiki/index.php? Title = % E7 % AE % A1 % E7 % 90% 86% E6 % 88% E5 % 90% 98 #. E8.8E. B7.E5.8F. 96. E6.88.90.E5.91.98

Description: After calling this interface, you will obtain the specific information of the Visitor registering with the enterprise number, such as name, number, mobile phone number, email address, and position.

④ Obtain logical User Information Based on Information

Description: The information obtained from the previous step can be used to match the business logic to obtain the user information in the business layer.

2. Sample Code 2.1 code (C #)

Logic: Asp.net determines the request sent by the client. If the request meets the rules on the enterprise number page, the enterprise number user identity authentication will be performed.

This function identifies three access requests:

1. The first access without code: OAuth Verification

2. There is code, no cookie: Get the information corresponding to the code

3. code and cookie: Verify the cookie

/// <Summary> /// Verify access /// </summary> public static void Auth (HttpContext webContext) {string requestURL = webContext. request. url. absoluteUri; try {// there are three types of user access pages: // 1. the first access, no code // 2. code, no cookie; // 3. code and cookie // 1. first visit, no code, no cookie: Jump to Oauth2.0 authentication if (string. isNullOrEmpty (webContext. request ["code"]) {string url = string. format ("https://open.weixin.qq.com/connect/oauth2/authorize?
