PHP实现curl post和get

CURL这里就不说明了。以下是简单案例

一、POST

//初始化
    $curl = curl_init();
    //设置抓取的url
    curl_setopt($curl, CURLOPT_URL, 'http://www.baidu.com');
    //设置头文件的信息作为数据流输出
    curl_setopt($curl, CURLOPT_HEADER, 1);
    //设置获取的信息以文件流的形式返回,而不是直接输出。
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    //设置post方式提交
    curl_setopt($curl, CURLOPT_POST, 1);
    //设置post数据
    $post_data = array(
        "username" => "coder",
        "password" => "12345"
        );
    curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
    //执行命令
    $data = curl_exec($curl);
    //关闭URL请求
    curl_close($curl);
    //显示获得的数据
    print_r($data);
POST

 private function _set_headers($user_agent , $client_ip )
    {
        $this->headers = [
            'Content-Type: application/json;charset=UTF-8',
            'Authorization: '. self::APP_KEY.':'.$this->sign,
            'Date: ' .$this->gmt_date,
            'Content-Length: ' .$this->content_len,
            'X-FORWARDED-FOR:'. $client_ip,
            'CLIENT-IP:'. $client_ip,
            'User-Agent:'.$user_agent
        ];
    }

    private function http_post_json($url, $jsonStr)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonStr);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
        //curl_setopt($ch,CURLOPT_PROXY,'118.0.0.1:8888');
        $response = curl_exec($ch);

        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        curl_close($ch);
        return ['code' => $httpCode, 'msg' => $response];
    }

二、GET

//初始化
    $curl = curl_init();
    //设置抓取的url
    curl_setopt($curl, CURLOPT_URL, 'http://www.baidu.com');
    //设置头文件的信息作为数据流输出
    curl_setopt($curl, CURLOPT_HEADER, 1);
    //设置获取的信息以文件流的形式返回,而不是直接输出。
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    //执行命令
    $data = curl_exec($curl);
    //关闭URL请求
    curl_close($curl);
    //显示获得的数据
    print_r($data);
GET

 //get获取合力token
    private function http_get_token()
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, self::GET_ACCESS_TOKEN_URL);
        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $data = curl_exec($ch);
        var_dump($data);die;
        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        curl_close($ch);
        return ['code' => $httpCode, 'msg' => CJSON::decode($data, true)];
    }
