It is a common solution for many customers to integrate with third-party websites. This section briefly describes how to obtain basic user information and directly log on to a third-party website.

When a public account pays attention to a public account, it generates a unique OpenID. In this case, we need to use it to request the server to obtain basic user information, including profile pictures and nicknames.

For more details, see the development documentation.

The procedure is as follows:

1 Step 1: The user agrees to the authorization and obtains the code
2 Step 2: Exchange code for webpage authorization access_token
3 Step 3: refresh access_token (if needed)
4. Step 4: Pull user information (the scope must be snsapi_userinfo)
5 Appendix: Check whether the authorization credential (access_token) is valid

1. On the public platform-Developer Center: webpage authorization to obtain basic user information: click "modify" to configure the webpage callback Domain Name

2. user authorization code

Required resources:

$ Appid = '*****************';
$ Appsecret = '*************************';

Note: redirect_url is the callback link address for redirection after authorization. Use urlencode to process the link.

Add the configured $ url = 'https: // open.weixin.qq.com/connect/oauth2/authorize? Appid = '. $ appid.' & redirect_uri = http % 3A % 2F % 2Fjixian.c.zmit.cn % 2F & response_type = code & scope = snsapi_userinfo & state = 123 & connect_redirect = 1 # wechat_redirect ';

And request an appeal url.

After authorization, the user calls back the domain name and Concatenates the required code in the url parameter. We can GET it directly with $ _ GET ['code!

3. Get the webpage authorization access_token and openid through code

$ Token_url = 'https: // api.weixin.qq.com/sns/oauth2/access_token? Appid = '. $ appid.' & secret = '. $ appsecret.' & code = '. $ code.' & grant_type = authorization_code ';
$ Token = json_decode (file_get_contents ($ token_url ));
$ Opendid = $ token-> openid;
$ Access_token = $ token-> access_token;

4. obtain user information

$ Info_url = 'https: // api.weixin.qq.com/sns/userinfo? Access_token = '. $ access_token.' & openid = '. $ opendid.' token = zh_CN ';
$ Info = json_decode (file_get_contents ($ info_url ));
$ Data ['name'] = $ info-> nickname;
$ Data ['image'] = $ info-> headimgurl;
Print_r ($ info );

5. After obtaining the user's openid and other information, we can save it to the database. As long as there is an openid, It is equivalent that the user has logged on to the website!

Use the access_token obtained by AppID and AppSecret to obtain basic user information through global Access Token.

1. You can obtain your OpenID when following and replying to a message.

   1372307736
   
  event
   
  subscribe
   
  
  
 

FromUserName indicates the OpenID.

2. Use the access_token interface to obtain the global Access Token.

Https://api.weixin.qq.com/cgi-bin/token? Grant_type = client_credential & appid = APPID & secret = APPSECRET
Returned results:

{ "access_token": "NU7Kr6v9L9TQaqm5NE3OTPctTZx797Wxw4Snd2WL2HHBqLCiXlDVOw2l-Se0I-WmOLLniAYLAwzhbYhXNjbLc_KAA092cxkmpj5FpuqNO0IL7bB0Exz5s5qC9Umypy-rz2y441W9qgfnmNtIZWSjSQ", "expires_in": 7200}

3. Use global ACCESS_TOKEN to obtain detailed information about OpenID.

Https://api.weixin.qq.com/cgi-bin/user/info? Access_token = ACCESS_TOKEN & openid = OPENID
The returned result is as follows:

{
"Subscribe": 1,
"Openid": "oLVPpjqs2BhvzwPj5A-vTYAX4GLc ",
