How to use php to query the current WeChat username

When developing WeChat applications, it is often necessary to obtain information about the current WeChat user, and username is also a relatively common requirement. In PHP, you can use some APIs to query the current WeChat username. Below we will introduce some common methods to help developers implement them quickly.

1. Use the API that comes with the WeChat Developer Tool

The WeChat Developer Tool comes with an API that can be used to obtain the information of the current WeChat user. You can use the following code to call:

$userInfo = $this->wxapi->getUserInfo();
$username = $userInfo->nickname;

Among them, $this->wxapi is the class name of WeChat API, which can be modified according to your actual situation. Call the getUserInfo() method to obtain the current WeChat user information. Note that this method requires that the user has authorized access to personal information.

After obtaining the user information, you can obtain the current WeChat username through $userInfo->nickname.

2. Use WeChat official API

In addition to the above methods, you can also use WeChat official API to achieve the function of obtaining WeChat username. You can use the following code to call:

$access_token = $this->wxapi->getAccessToken();
$openid = $this->wxapi->getOpenId();
$url = "https://api.weixin.qq.com/cgi-bin/user/info?access_token={$access_token}&openid={$openid}&lang=zh_CN";
$userInfo = json_decode(file_get_contents($url));
$username = $userInfo->nickname;

Among them, $this->wxapi is also the class name of WeChat API, which can be modified according to your actual situation. Call the getAccessToken() and getOpenId() methods to obtain the current user's access_token and openid. Then, use the spliced ​​URL to request the API to obtain user information, and then convert the returned JSON data into an object through json_decode(). Finally, you can get the current WeChat username through $userInfo->nickname.

3. Use third-party SDK

In addition to the above two methods, there are also some functions in the third-party SDK of PHP that can achieve the function of obtaining WeChat username. For example, using Easywechat SDK, you can use the following code to call:

$app = new EasyWeChat\Foundation\Application($options);
$user = $app->user->get($openid);
$username = $user->nickname;
