创建控制器

php artisan make:controller WeChatController

获取code和token

 public function wxcode()
    {
        //一定要按照参数的顺序进行排列，否则接口将无法访问
        $params = http_build_query([
            'appid' => '微信公众号的appid',
            'redirect_uri' => '自己的域名/wxtoken',
            'response_type' => 'code',
            'scope' => 'snsapi_userinfo'
        ]);
        $url = 'https://open.weixin.qq.com/connect/oauth2/authorize?'.$params .'#wechat_redirect';
        return redirect($url);
    }


    public function wxtoken(Request $request)
    {
      $code = $request->input('code');
      $params = http_build_query([
        'appid' => '微信公众号的appid',
        'secret'=> '微信公众号的appsecret',
        'code' => $code,
        'grant_type' => 'authorization_code'
      ]);
      $url = 'https://api.weixin.qq.com/sns/oauth2/access_token?'.$params;
      $result = json_decode(file_get_contents($url));
      // dd($result);
      $params = http_build_query([
        'access_token' => $result->access_token,
        'openid' => $result->openid,
        'lang' => 'zh_CN',
      ]);
      $url = 'https://api.weixin.qq.com/sns/userinfo?'.$params;
      $UserInfo = json_decode(file_get_contents($url));
      dd($UserInfo);
    }

配置路由

Route::get('wxcode','WeChatController@wxcode');
Route::get('wxtoken','WeChatController@wxtoken');

在微信开发者工具上访问 域名/wxcode 就可以获取到用户信息了
