php如何发起POST DELETE GET POST 请求

 

get:是用来取得数据。其要传递过的信息是拼在url后面，因为其功能使然，有长度的限制

post:是用来上传数据。要上传的数据放在request的head里。没有长度限制。主要是用于增加操作

put:也是用来上传数据。但是一般是用在具体的资源上。主要用于修改操作

delete:用来删除某一具体的资源上

发起POST DELETE GET POST 请求通用类

    <?php   
    class commonFunction{  
        function callInterfaceCommon($URL,$type,$params,$headers){  
            $ch = curl_init();  
            $timeout = 5;  
            curl_setopt ($ch, CURLOPT_URL, $URL); //发贴地址  
            if($headers!=""){  
                curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);  
            }else {  
                curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type: text/json'));  
            }  
            curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);  
            curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);  
            switch ($type){  
                case "GET" : curl_setopt($ch, CURLOPT_HTTPGET, true);break;

            $file_contents = curl_exec($ch);//获得返回值  
            return $file_contents;

$url=$GLOBALS["serviceUrl"]."/user";  
$strResult= spClass("commonFunction")->callInterfaceCommon($url,"PUT",$params,$headers);
