PHP发起POST DELETE GET POST 请求

原文链接：http://blog.csdn.net/lengxue789/article/details/8254667

关于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, $URL);//目标地址
         //请求头
         if($headers!=""){
             curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);
         }else {
             curl_setopt ($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
         }
         curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);//返回结果，不输出
         curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);//超时时间
         //请求类型
         switch ($type){
             case "GET" :
             curl_setopt($ch, CURLOPT_HTTPGET, true);
             break;
             case "POST":
             curl_setopt($ch, CURLOPT_POST,true);
             curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
             break;
             case "PUT" :
             curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "PUT");
             curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
             break;
             case "DELETE":
             curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
             curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
             break;
         }
         $file_contents = curl_exec($ch);//获得返回值
         curl_close($ch);
         return $file_contents;
     }
 }
 ?>

调用

 <?php
 $params="{user:\"admin\",pwd:\"admin\"}";
 $headers=array('Content-type: text/json',"id: $ID","key:$Key");
 $url=$GLOBALS["serviceUrl"]."/user";
 $strResult= spClass("commonFunction")->callInterfaceCommon($url,"PUT",$params,$headers);
 ?>

$headers：如果参数值需要header传，可以以数组格式传递
