[原]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

<?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
