Detailed explanation of ThinkPHP6 combined with GuzzleHTTP to send HTTP requests

The following tutorial column will introduce you to ThinkPHP6 and GuzzleHTTP to send HTTP requests. I hope it will be helpful to friends in need! ThinkPHP6 combines GuzzleHTTP to send HTTP requests

Background

thinkphp WeChat public account program actively calls the WeChat interface and needs access_token, and You need to proactively send a request to set up the official account menu.

Why choose GuzzleHTTP

Guzzle is a PHP HTTP client used to easily send requests and integrate into our WEB services.

接口简单：构建查询语句、POST请求、分流上传下载大文件、使用HTTP cookies、上传JSON数据等等。
发送同步或异步的请求均使用相同的接口。
使用PSR-7接口来请求、响应、分流，允许你使用其他兼容的PSR-7类库与Guzzle共同开发。
抽象了底层的HTTP传输，允许你改变环境以及其他的代码，如：对cURL与PHP的流或socket并非重度依赖，非阻塞事件循环。
中间件系统允许你创建构成客户端行为。

2. Install Guzzle

Enter the tp project directory

 cd /Applications/XAMPP/htdocs/tp1/tp

Execute the installation command

composer require guzzlehttp/guzzle

3.Open

extension=php_openssl.dll## in the php.ini document

#Send http get sample code

1. Introduce GuzzleHttp in the controller<pre class="brush:php;toolbar:false">use GuzzleHttp\Client; use GuzzleHttp\Exception\GuzzleException;</pre>2. The following sample program uses HTTP GET to obtain the access token of the WeChat public platform in tp6

       //微信公众平台获取access token url
        $url = 'https://api.weixin.qq.com/cgi-bin/token?';
       //获取access token时需要携带的参数
        $params = array(
            'grant_type' => 'client_credential',
            'appid' => config('app.WECHAT.APPID'),
            'secret' => config('app.WECHAT.SECRET')
        );
        $resp = null;
        try {
           //使用GuzzleHTTP发送get请求
            $client = new Client();
            $resp = $client->request('GET', $url.http_build_query($params));
        } catch (GuzzleException $e){
            print($e);
        }

        if (empty($resp)) {
            return null;
        }
        //获取微信公众平台的response
        $data = json_decode($resp->getBody(), true);
        if (isset($data['errcode']) && $data['errcode'] != 0) {
            throw new \think\Exception ($data['errmsg'], $data['errcode']);
        }

Send http post sample code

The usage is very simple, just look at the code.

    /**
     * 创建自定义菜单
     */
    public function menu()
    {
        require __DIR__ . '/../../vendor/autoload.php';
        //构建HTTP post JSON body数据
        $data = array(
            'button' => array(
                array(
                    'type' => 'click',
                    'name' => '主菜单1',
                    'sub_button' => array(
                        array(
                            'type' => 'click',
                            'name' => '子菜单1',
                            'key' => self::MENU_MAIN_1_CHILD_1
                        ),
                        array(
                            'type' => 'view',
                            'name' => '百度',
                            'url' => 'https://www.baidu.com'
                        )
                    )
                ),
                array(
                    'type' => 'click',
                    'name' => '主菜单2',
                    'sub_button' => array(
                        array(
                            'type' => 'click',
                            'name' => '子菜单1',
                            'key' => self::MENU_MAIN_2_CHILD_1
                        ),
                        array(
                            'type' => 'view',
                            'name' => 'QQ',
                            'url' => 'http://www.qq.com'
                        )
                    )
                ),
                array(
                    'type' => 'click',
                    'name' => '主菜单3',
                    'key' => self::MENU_MAIN_3
                )
            )
        );
        //构造请求json body和header数据
        $options = json_encode($data, JSON_UNESCAPED_UNICODE);
        $jsonData = [
            'body' => $options,
            'headers' => ['content-type' => 'application/json']
        ];

        $resp = null;
        try {
            $client = new Client();
            //生成微信公众号菜单需要调用的微信接口url
            $url = 'https://api.weixin.qq.com/cgi-bin/menu/create?access_token=' . $this->_getAccessToken();
            //发送http post请求
            $resp = $client->post($url, $jsonData);
        } catch (GuzzleException $e){
            print($e);
        }


        if (empty($resp)) {
            return null;
        }

        echo $resp->getBody();
    }
