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 thegetUserInfo()
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 thegetAccessToken()
andgetOpenId()
methods to obtain the current user'saccess_token
andopenid
. Then, use the spliced URL to request the API to obtain user information, and then convert the returned JSON data into an object throughjson_decode()
. Finally, you can get the current WeChat username through$userInfo->nickname
.

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