Methods called by commonly used interfaces in PHP user management

This article mainly introduces the common interface calling methods in PHP user management. Interested friends can refer to it. I hope it will be helpful to everyone.

The first step to master users is to save the information of fans you have followed. At this time, you will use the user list interface. The public account can obtain the account's follower list through this interface. The follower list consists of a string of OpenIDs (encrypted WeChat IDs, each user's OpenID for each public account is unique). A single pull call can pull up to 10,000 OpenIDs of followers, and you can pull multiple times to meet your needs.

1. Get the WeChat following user list interface calling example

Interface description

http request method: GET

Interface calling address ：

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

Request parameter description, as shown in the table:

Parameters	Is it required	Description
access_token	is the	calling interface credential
next_openid	is the first OPENID pulled by	, if not filled in, it will be pulled from scratch by default

Return instructions:

Under normal circumstances, WeChat will return a JSON data packet to the official account, as follows Shown:

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

Return information parameter description, as shown in the table:

Parameters	Description
##total	Total number of people following this public account Number of users
count	The number of OPENIDs pulled, the maximum value is 10000
data	List data, list of OPENID
next_openid	Get the OPENID of the last user in the pull list

Use the program call interface to obtain, code:

<?php
/*
 *获取微信关注用户列表OpenID
*/
require(&#39;wei_function.php&#39;);
$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[&#39;access_token&#39;];
//获取关注用户列表接口
$userurl="https://api.weixin.qq.com/cgi-bin/user/get?access_token=".$token."";
//通过getdata进行接口调用
$userarr=(array)json_decode(getdata($userurl));
//将返回信息进行处理并输出
$useropenidarr=(array)$userarr[&#39;data&#39;];
print_r($useropenidarr);
?>

Code analysis

require('wei_function.php'); contains wei_function.php. This function file can be purchased from "WeChat Public Platform Development Example Tutorial" ", which is explained in detail on page 95 of the book.

is the same as the WeChat public platform development 3-WeChat server IP interface instance (including source code) for obtaining the WeChat server IP. After obtaining the access_token, replace

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

access_token parameter, and get the return through the getdata() function The information is processed and printed, as shown in the figure.

If the following users are more than 10,000 and need to be called multiple times, just add the parameter &next_openid=NEXT_OPENID after the interface. NEXT_OPENID will return this value in the previous call, such as ：

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

2. User basic information interface (UnionID mechanism) calling example

Get the list of following users After the interface obtains the user's OpenID, it can use this parameter and call the interface to obtain the user's basic information (UnionID mechanism) to obtain the user's basic information, such as: nickname, city, gender, user avatar, whether to follow the official account, etc., in order to better To understand the user, this information needs to be saved together in the database.

Interface Description

http request method: GET

Interface calling address:

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

Request parameter description, as shown in the table:

# #lang

返回说明：

正常情况下，微信会返回JSON数据包给公众号，如下所示：

{
  "subscribe": 1,
  "openid": "o6_bmjrPTlm6_2sgVt7hMZOPfL2M",
  "nickname": "Band",
  "sex": 1,
  "language": "zh_CN",
  "city": "广州",
  "province": "广东",
  "country": "中国",
  "headimgurl": "http://wx.qlogo.cn/mmopen/g3MonUZtNHkdmzicIlibx6iaFqAc56vxLSUfpb6n5WKSYVY0ChQKkiaJSgQ1dZuTOgvLLrhJbERQQ4
eMsv84eavHiaiceqxibJxCfHe/0",
 "subscribe_time": 1382694957,
 "unionid": " o6_bmasdasdsad6_2sgVt7hMZOPfL"
 "remark": "",
 "groupid": 0,
 "tagid_list":[128,2]
}

返回信息参数说明，如表所示：

Parameter	Is it necessary	Description
access_token	is the	calling interface credential
openid	is the identifier of an ordinary user	, unique to the current public account
##No	Return to the country and region language version, zh_CN simplified, zh_TW traditional, en English

参数	说明
subscribe	用户是否订阅该公众号标识，值为0时，代表此用户没有关注该公众号，拉取不到其余信息。
openid	用户的标识，对当前公众号唯一
nickname	用户的昵称
sex	用户的性别，值为1时是男性，值为2时是女性，值为0时是未知
city	用户所在城市

tagid_list	用户被打上的标签ID列表

使用程序调用接口获取，代码：

<?php
/*
 *获取微信关注用户基本信息
*/
require(&#39;wei_function.php&#39;);
$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[&#39;access_token&#39;];
//获取关注用户列表接口
$userurl="https://api.weixin.qq.com/cgi-bin/user/get?access_token=".$token."";
//通过getdata进行接口调用
$userarr=(array)json_decode(getdata($userurl));
//将返回信息进行处理并输出
$useropenidarr=(array)$userarr[&#39;data&#39;];
foreach ($useropenidarr[&#39;openid&#39;] as $value) {
  //循环获取用户基本信息
  $infourl="https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$token."&openid=".$value."&lang=zh_CN";
  $infoarr=(array)json_decode(getdata($infourl));
  print_r($infoarr);
  echo "<br />";
}
?>

代码解析

require('wei_function.php');包含wei_function.php，该函数文件可以购买《微信公众平台开发实例教程》，在该书中第95页有详细讲解。

获取到用户OpenID列表后，根据每条OpenID获取用户基本信息，这里用到foreach循环

foreach ($useropenidarr['openid'] as $value) {
    //循环获取用户基本信息
   $infourl="https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$token."&openid=".$value."&lang=zh_CN";
    $infoarr=(array)json_decode(getdata($infourl));
    print_r($infoarr);
    echo "<br />";
}

运行结果如图所示。

如果需要将用户信息保存到数据库，只需替换print_r($infoarr);为增加数据库的代码即可，如：

foreach ($useropenidarr['openid'] as $value) {
  //循环获取用户基本信息
  $infourl="https://api.weixin.qq.com/cgi-bin/user/info?access_token=".$token."&openid=".$value."&lang=zh_CN";
  $infoarr=(array)json_decode(getdata($infourl));
  //将用户信息增加到数据库
　　 $sql=”insert into userinfo(`nickname`,`sex`,`city`) values
　　 (‘”.$infoarr[‘nickname'].”','”.$infoarr['sex'].”','”.$infoarr['city'].”')”;
  mysql_query($sql);
}

以上就是本文的全部内容，希望对大家的学习有所帮助。
