Develop WeChat public platform to obtain basic user information

This article introduces how to obtain the basic information of users followed on the WeChat public platform, including nickname, avatar, gender, country, province, city, and language.
The method in this article will cover various scenarios of subscription accounts, service accounts, and custom menus. Regardless of whether you have advanced interface permissions or not, there are ways to obtain basic user information without simulating login.

In this article, special attention should be paid to the fact that there are two different Access Tokens. They are generated in different ways. One is the access_token obtained using AppID and AppSecret, and the other is OAuth2.0 The access_token generated during authorization is called global Access Token and authorized Access Token by Fangbei Studio respectively.

1. Obtain the user’s basic information through the global Access Token

When the user follows and replies to the message, the user’s information can be obtained OpenID

<xml>

    <FromUserName><![CDATA[ollB4jv7LA3tydjviJp5V9qTU_kA]]></FromUserName>
    <CreateTime>1372307736</CreateTime>
    <MsgType><![CDATA[event]]></MsgType>
    <Event><![CDATA[subscribe]]></Event>
    <EventKey><![CDATA[]]></EventKey></xml>

The FromUserName is OpenID

Then use the access_token interface to request the global Access Token

Return result:

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