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

 1 <?php
 2 class commonFunction{
 3     function callInterfaceCommon($URL,$type,$params,$headers){
 4         $ch = curl_init();
 5         $timeout = 5;
 6         curl_setopt ($ch, CURLOPT_URL, $URL);//目标地址
 7         //请求头
 8         if($headers!=""){
 9             curl_setopt ($ch, CURLOPT_HTTPHEADER, $headers);
10         }else {
11             curl_setopt ($ch, CURLOPT_HTTPHEADER, array(‘Content-type: text/json‘));
12         }
13         curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);//返回结果，不输出
14         curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);//超时时间
15         //请求类型
16         switch ($type){
17             case "GET" :
18             curl_setopt($ch, CURLOPT_HTTPGET, true);
19             break;
20             case "POST":
21             curl_setopt($ch, CURLOPT_POST,true);
22             curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
23             break;
24             case "PUT" :
25             curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "PUT");
26             curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
27             break;
28             case "DELETE":
29             curl_setopt ($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
30             curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
31             break;
32         }
33         $file_contents = curl_exec($ch);//获得返回值
34         curl_close($ch);
35         return $file_contents;
36     }
37 }
38 ?>

调用

1 <?php
2 $params="{user:\"admin\",pwd:\"admin\"}";
3 $headers=array(‘Content-type: text/json‘,"id: $ID","key:$Key");
4 $url=$GLOBALS["serviceUrl"]."/user";
5 $strResult= spClass("commonFunction")->callInterfaceCommon($url,"PUT",$params,$headers);
6 ?>

$headers：如果参数值需要header传，可以以数组格式传递
