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, $URL); //发贴地址if($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($ch, CURLOPT_HTTPGET, true);break;case "POST": curl_setopt($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return $file_contents;curl_close($ch);}}?>

调用：

$params="{user:\"admin\",pwd:\"admin\"}";$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
