php 通过curl post发送json数据实例

利用php curl发送json数据与curl post其它数据是一样的,下面我来给大家总结几个关于curl post发送json数据实例,希望能加深各位对curl post json数据的理解吧。

例1代码如下:

1. $data = array("name" => "Hagrid", "age" => "36");                                                                   
2. $data_string = json_encode($data);                                                                                   
3.  
4. $ch = curl_init('http://api.local/rest/users');                                                                     
5. curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
6. curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                 
7. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                     
8. curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                         
9.     'Content-Type: application/json',                                                                               
10.     'Content-Length: ' . strlen($data_string))                                                                       
11. );                                                                                                                   
12.  
13. $result = curl_exec($ch); 

例2,代码如下:

1. function http_post_data($url, $data_string) { 
2.         $ch = curl_init(); 
3.         curl_setopt($ch, CURLOPT_POST, 1); 
4.         curl_setopt($ch, CURLOPT_URL, $url); 
5.         curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string); 
6.         curl_setopt($ch, CURLOPT_HTTPHEADER, array( 
7.             'Content-Type: application/json; charset=utf-8', 
8.             'Content-Length: ' . strlen($data_string)) 
9.         ); 
10.         ob_start(); 
11.         curl_exec($ch); 
12.         $return_content = ob_get_contents(); 
13.         ob_end_clean(); 
14.         $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
15.         return array($return_code, $return_content); 
16.     } 
17. $url  = "http://xx.xx.cn"; 
18. $data = json_encode(array('a'=>1, 'b'=>2)); 
19. list($return_code, $return_content) = http_post_data($url, $data); 

例3代码如下:

1. $data=' { 
2.      "button":[ 
3.      {     
4.           "type":"click", 
5.           "name":"今日歌曲", 
6.           "key":"V1001_TODAY_MUSIC" 
7.       }, 
8.       { 
9.            "type":"click", 
10.            "name":"歌手简介", 
11.            "key":"V1001_TODAY_SINGER" 
12.       }, 
13.       { 
14.            "name":"菜单", 
15.            "sub_button":[ 
16.             { 
17.                "type":"click", 
18.                "name":"hello word", 
19.                "key":"V1001_HELLO_WORLD" 
20.             }, 
21.             { 
22.                "type":"click", 
23.                "name":"赞一下我们", 
24.                "key":"V1001_GOOD" 
25.             }] 
26.        }] 
27.  }'; 
28. $ch = curl_init($urlcon); //请求的URL地址 
29. curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 
30. curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//$data JSON类型字符串 
31. curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
32. curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length: ' . strlen($data))); 
33. $data = curl_exec($ch); 
34. print_r($data);//创建成功返回：{"errcode":0,"errmsg":"ok"} 

小结,我们发现最核心的一句代码就是Content-Type: application/json;这个是文件格式类型了.
