模拟post请求
方法一：

/*json请求*/
function http_post_data($url, $data_string) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            "Content-Type: application/json; charset=utf-8",
            "Content-Length: " . strlen($data_string))
    );
    ob_start();
    curl_exec($ch);
    $return_content = ob_get_contents();
    ob_end_clean();
    $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    return $return_content;
}

方法二：

public function httpPostData($url, $data_string){

        $cacert = ''; //CA根证书  (目前暂不提供)
        $CA = false ;   //HTTPS时是否进行严格认证
        $TIMEOUT = 30;  //超时时间(秒)
        $SSL = substr($url, 0, 8) == "https://" ? true : false;
        
        $ch = curl_init ();
        if ($SSL && $CA) {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);   //  只信任CA颁布的证书
            curl_setopt($ch, CURLOPT_CAINFO, $cacert);      //  CA根证书（用来验证的网站证书是否是CA颁布）
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);    //  检查证书中是否设置域名，并且是否与提供的主机名匹配
        } else if ($SSL && !$CA) {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);  //  信任任何证书
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);    //  检查证书中是否设置域名
        }


        curl_setopt ( $ch, CURLOPT_TIMEOUT, $TIMEOUT);
        curl_setopt ( $ch, CURLOPT_CONNECTTIMEOUT, $TIMEOUT-2);
        curl_setopt ( $ch, CURLOPT_POST, 1 );
        curl_setopt ( $ch, CURLOPT_URL, $url );
        curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data_string );
        curl_setopt ( $ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json') );
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        ob_start();
        curl_exec($ch);
        $return_content = ob_get_contents();
        ob_end_clean();

        $return_code = curl_getinfo ( $ch, CURLINFO_HTTP_CODE );
       
        curl_close($ch);
        return array (
            $return_code,
            $return_content
        );
    }

方法三：

 //HTTP请求（支持HTTP/HTTPS，支持GET/POST）
function http_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, TRUE);
    $output = curl_exec($curl);
    curl_close($curl);
    return $output;
}

方法四：

function httpPost($url, $paramStr){
		$curl = curl_init();
		curl_setopt_array($curl, array(
		  CURLOPT_URL => $url,
		  CURLOPT_RETURNTRANSFER => 1,
		  CURLOPT_TIMEOUT => 30,
		  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
		  CURLOPT_CUSTOMREQUEST => "POST",
		  CURLOPT_POSTFIELDS => $paramStr,
		  CURLOPT_SSL_VERIFYPEER => 0,
		  CURLOPT_SSL_VERIFYHOST => 0,
		  CURLOPT_HTTPHEADER => array(
			"cache-control: no-cache",
			"content-type: application/x-www-form-urlencoded"
		  ),
		));
		$response = curl_exec($curl);
		$err = curl_error($curl);
		curl_close($curl);
		if ($err) {
		  return $err;
		}
		return $response;
	}

方法五：

public static function postForm($url, $data, $headers = [], $referer = NULL)
    {
        $headerArr = [];
        if (is_array($headers)) {
            foreach ($headers as $k => $v) {
                $headerArr[] = $k . ': ' . $v;
            }
        }
        $headerArr[] = 'Content-Type: application/x-www-form-urlencoded; charset=utf-8';

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_TIMEOUT, 30);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headerArr);
        if ($referer) {
            curl_setopt($ch, CURLOPT_REFERER, "http://{$referer}/");
        }
        $data = curl_exec($ch);
        curl_close($ch);

        return $data;
    }

方法六：

 function request_post($url = '', $param = '')
	{
		if (empty($url) || empty($param)) {
			return false;
		}
		$postUrl = $url;
		$curlPost = $param;
		
		
		$curl = curl_init();
		curl_setopt($curl, CURLOPT_URL, $postUrl);
		curl_setopt($curl, CURLOPT_USERAGENT,'Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15');
		curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // stop verifying certificate
		curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
		curl_setopt($curl, CURLOPT_POST, true);
		curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
		curl_setopt($curl, CURLOPT_POSTFIELDS, $curlPost);
		curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
		$data = curl_exec($curl); 
		curl_close($curl);
	
		return $data;
	}

方法七：

模拟get提交

方法一：

$re = file_get_contents($url);
print_r($re);

方法二：

$ch = curl_init("http://www.jb51.net/") ; 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; 
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ; 
$output = curl_exec($ch) ; 
$fh = fopen("out.html", 'w') ; 
fwrite($fh, $output) ; 
fclose($fh) ;

方法三：

function http_get1($url)
	{
		  $curl = curl_init(); // 启动一个CURL会话
		    curl_setopt($curl, CURLOPT_URL, $url);
		    curl_setopt($curl, CURLOPT_HEADER, 0);
		    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
		    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查
		    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);  // 从证书中检查SSL加密算法是否存在
		    $tmpInfo = curl_exec($curl);     //返回api的json对象
		    //关闭URL请求
		    curl_close($curl);
		    return $tmpInfo;    //返回json对象
	}
