         <button class="login-wxpng" open-type="getUserInfo" @getuserinfo="xcxWxLogin">
                    微信小程序登录
         </button>
    </view>
</template>

<script>
    export default {
        data() {
            return {
                
            }
        },
        methods: {
           xcxWxLogin() {
                uni.login({
                    provider: 'weixin',
                    success: function(res) {
                        console.log("微信登录的res结果:");
                        console.log(res);
                        
                        //开始获取openid
                        if (res.code) {
                            //发起网络请求
                            uni.request({
                                method: 'GET',
                                url: 'http://api.lhdtest.com/auth/xcxuserinfo',
                                data: {
                                        app_key: 'wxxcx',
                                        v: '2.75',
                                        code: res.code,
                                },
                                success(res) {
                                        console.log('xcxuserinfo:');
                                        console.log(res);
                                }
                            })
                        } else {
                            console.log('登录失败！' + res.errMsg)
                        }
                        
                    },

二，服务端php代码：

class Auth extends BaseController
{
   private string $appId = 'wxnideappid';
   private string $appSecret = 'nideappsecret';

    //根据code得到微信用户的信息
    public function xcxUserInfo(){
        $code = $this->request->param('code','','string');
        $result=$this->getSession($code);
        var_dump($result);
    }

    //用code得到微信的session信息，包含用户id
    public function getSession($code){
        $s_data = array();
        $s_data['appid'] = $this->appId;
        $s_data['secret'] = $this->appSecret;
        $s_data['js_code'] = $code;
        $s_data['grant_type']="authorization_code";
        $session_url = 'https://api.weixin.qq.com/sns/jscode2session?' . http_build_query ( $s_data );
        $content = file_get_contents ( $session_url );
        $content = json_decode ( $content, true );
        $content['appid']=$s_data['appid'];
        return $content;
    }
}
