This article brings you what are the request methods of Curl in php? The introduction of the four request methods of php curl has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

1. Send json format data, request address: https

protected function https_request($url,$data=null){
    $curl = curl_init();
    curl_setopt($curl,CURLOPT_URL,$url);
    curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,FALSE);
    curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,FALSE);
    if(!empty($data)){
        curl_setopt($curl,CURLOPT_POST,1);
        curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
    }
    curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
    //下面这行是修改后增加的代码，就是配置设置host访问，发送的数据类型为application/json
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json; charset=utf-8',
        'Content-Length: ' . strlen($data)
    ));
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}

2. Send json format data, request address: http

protected function curlPost($Url, $data){
    $ch = curl_init($Url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//$data JSON类型字符串
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data)));
    $result = curl_exec($ch);
    curl_close ( $ch );
    return $result;
}

3. Submit form format

function file_get_contents_post($url, $post){
    $options = array(
        'http'=> array(
        'method'=>'POST',
        'header' => "Content-type: application/x-www-form-urlencoded ",
        'content'=> http_build_query($post),
        ),
    );
    $result = file_get_contents($url,false, stream_context_create($options));
    return $result;
}
$datare = file_get_contents_post("http://103.72.165.183/api/payment.aspx", $data);
var_dump($datare);

4. $url is the form of address plus data: http://baidu.com?a="ss"&b="ds";

public function getSSLHttp($url){
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_HEADER, false);
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        $data = curl_exec($curl);
        $httpCode = curl_getinfo($curl,CURLINFO_HTTP_CODE);
        if ( $httpCode != 200 ){
            $data="https connect timeout";
        }
        curl_close($curl);
        return $data;
    }
