The first step to grasp the user is to save the followers information that has been followed, and the interface for getting the user list is used. The public account can be obtained through this interface. The list of accounts is composed of a string of openids (encrypted numbers, each user has a unique OpenID for each public account. One pull call can pull the OpenID of up to 10000 referers. You can use multiple pull requests to meet your requirements.

1. Obtain the list of users that follow the user list interface to call the instance

Interface Description

Http Request Method: GET

Interface call address:

Https://api.weixin.qq.com/cgi-bin/user/get? Access_token = ACCESS_TOKEN & next_openid = NEXT_OPENID

The request parameters are described in the following table:

Parameters	Required?	Description
Access_token	Yes	Interface call credential
Next_openid	Yes	The first OPENID to be pulled. If this parameter is not specified, the OPENID is pulled from the beginning by default.

Return description:

Under normal circumstances, a JSON data packet is returned to the public number, as shown below:

{"Total": 2, "count": 2, "data": {"openid": ["", "OPENID1", "OPENID2"]}, "next_openid ": "NEXT_OPENID "}

The following table describes the response parameters:

Parameters	Description
Total	Follow the total number of users of this public account
Count	The number of openids pulled. The maximum value is 10000.
Data	List data, OPENID list
Next_openid	Pull the OPENID of the last user in the list

Use the program to call the interface to obtain the Code:

<? Php/** get follow user list OpenID */require ('wei _ function. php '); $ appid = "wx78478e595939c538"; $ secret = "5540e8ccab4f71dfad752f73cfb85780"; $ url = "https://api.weixin.qq.com/cgi-bin/token? Grant_type = client_credential & appid = ". $ appid. "& secret = ". $ secret. ""; $ output = getdata ($ url); $ tokenarr = (array) json_decode ($ output); $ token = $ tokenarr ['Access _ token']; // get follow user list interface $ userurl = "https://api.weixin.qq.com/cgi-bin/user/get? Access_token = ". $ token. ""; // call $ userarr = (array) json_decode (getdata ($ userurl) through the getdata interface; // process the returned information and output $ useropenidarr = (array) $ userarr ['data']; print_r ($ useropenidarr);?>

Code Parsing

Require ('wei _ function. php'); contains wei_function.php. You can purchase the function file "public platform development instance tutorial", which is detailed on page 95th.

Similar to public platform development 3-Server IP interface instance (including source code), after obtaining access_token, replace

$ Userurl = "https://api.weixin.qq.com/cgi-bin/user/get? Access_token = ". $ token ."";

The access_token parameter in, and get the returned information through the getdata () function. After processing, print it ,.

If you want to focus on more than 10000 users, you only need to add the & next_openid = NEXT_OPENID parameter after the interface. NEXT_OPENID will return this value in the previous call, for example:

$ Userurl = "https://api.weixin.qq.com/cgi-bin/user/get? Access_token = ". $ token." & next_openid = NEXT_OPENID ";

Ii. Call the instance through the basic user information interface (UnionID mechanism)

After obtaining the user's OpenID through the follow user list interface, you can obtain the user's basic information through this parameter and call the get user basic information (UnionID mechanism) interface, for example: nickname, city, gender, user profile picture, whether to pay attention to public accounts and other information. To better understand users, you need to save the information to the database together.

Interface Description

Http Request Method: GET

Interface call address:

Https://api.weixin.qq.com/cgi-bin/user/info? Access_token = ACCESS_TOKEN & openid = OPENID & lang = zh_CN

The request parameters are described in the following table:

Parameters	Required?	Description
Access_token	Yes	Interface call credential
Openid	Yes	The identifier of a common user, which is unique to the current public account.
Lang	No	Return to the Chinese language version, zh_CN simplified, zh_TW traditional, en english

Return description:

Under normal circumstances, a JSON data packet is returned to the public number, as shown below:

{

"Subscribe": 1,

"Openid": "o6_bmjrPTlm6_2sgVt7hMZOPfL2M ",

"Nickname": "Band ",

"Sex": 1,

"Unionid": "o6_bmasdasdsad6_2sgVt7hMZOPfL"

"Remark ":"",

"Groupid": 0,

"Tagid_list": []

}

The following table describes the response parameters:

Parameters	Description

Openid	User ID, which is unique to the current public account
Nickname	User nickname
Sex	Gender of the user. If the value is 1, the user is male. If the value is 2, the user is female. If the value is 0, the user is unknown.

Headimgurl	User profile picture. The last value indicates the size of the square profile picture (optional values include 0, 46, 64, 96, and 132, and 0 indicates the size of the 640x640 square profile picture ), this item is blank when the user does not have an avatar. If you change the profile picture, the original profile picture URL becomes invalid.
Subscribe_time	The user's attention time, which is the timestamp. If the user has followed the last time
Unionid	This field appears only when you bind a public account to an open platform account.
Remark	Comments from public account operators to fans. Public Account operators can add comments to fans in the user management field of the public platform.
Groupid	ID of the user's group (compatible with the old user group Interface)
Tagid_list	User ID list

Use the program to call the interface to obtain the Code:

<? Php/** get basic user information */require ('wei _ function. php '); $ appid = "wx78478e595939c538"; $ secret = "5540e8ccab4f71dfad752f73cfb85780"; $ url = "https://api.weixin.qq.com/cgi-bin/token? Grant_type = client_credential & appid = ". $ appid. "& secret = ". $ secret. ""; $ output = getdata ($ url); $ tokenarr = (array) json_decode ($ output); $ token = $ tokenarr ['Access _ token']; // get follow user list interface $ userurl = "https://api.weixin.qq.com/cgi-bin/user/get? Access_token = ". $ token. ""; // call $ userarr = (array) json_decode (getdata ($ userurl) through the getdata interface; // process the returned information and output $ useropenidarr = (array) $ userarr ['data']; foreach ($ useropenidarr ['openid'] as $ value) {// get user basic information cyclically $ infourl = "https://api.weixin.qq.com/cgi-bin/user/info? Access_token = ". $ token. "& openid = ". $ value. "& lang = zh_CN"; $ infoarr = (array) json_decode (getdata ($ infourl); print_r ($ infoarr); echo "<br/>" ;}?>

Code Parsing

Require ('wei _ function. php'); contains wei_function.php. You can purchase the function file "public platform development instance tutorial", which is detailed on page 95th.

After obtaining the user's OpenID list, obtain the user's basic information based on each OpenID. The foreach loop is used here.

Foreach ($ useropenidarr ['openid'] as $ value ){

// Obtain basic user information cyclically

$ Infourl = "https://api.weixin.qq.com/cgi-bin/user/info? Access_token = ". $ token." & openid = ". $ value." & lang = zh_CN ";

$ Infoarr = (array) json_decode (getdata ($ infourl ));

Print_r ($ infoarr );

Echo "<br/> ";

}

Running result.

To save user information to the database, simply replace print_r ($ infoarr) with the code for adding the database, as shown in:

Foreach ($ useropenidarr ['openid'] as $ value) {// get basic user information cyclically $ infourl = "https://api.weixin.qq.com/cgi-bin/user/info? Access_token = ". $ token. "& openid = ". $ value. "& lang = zh_CN"; $ infoarr = (array) json_decode (getdata ($ infourl )); // Add User information to the database $ SQL = "insert into userinfo ('nickname', 'sex', 'city') values ('". $ infoarr ['nickname']. "','". $ infoarr ['sex']. "','". $ infoarr ['city']. "')"; mysql_query ($ SQL );}
