====== PHP 如何发起 POST DELETE GET POST 请求 ====== 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 <code> <?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); } } ?> <code> 调用： <code> $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); </code> $headers：如果参数值需要header传，可以以数组格式传递
