Problems with PHP Curl post data

There was a particularly strange problem today when doing a function of API increments. When I used curl to try Tomcat post data, Tomcat actually made an error, and the data I post

Not correct or to get. However, I use Curl post to a page I wrote myself, and I can get the data in the $_post array.

Why is there such a problem?

The reason is that there is a problem building the number of post data ...

  
     

      
   1 function api_notice_increment ($url, $data)
   
      
2 {
   
      
3     $ch = Curl_init ();        
   
      
4     curl_setopt ($ch, curlopt_header,0);
   
      
5     curl_setopt ($ch, Curlopt_returntransfer, 1);
   
      
6 
   
      
7     curl_setopt ($ch, Curlopt_url, $url);
   
      
8     curl_setopt ($ch, Curlopt_post, 1);
   
      
9     curl_setopt ($ch, Curlopt_postfields, $data);
   
      
     $lst [' rst '] = curl_exec ($ch);
   
      
One      $lst [' info '] = curl_getinfo ($ch);
   
      
     curl_close ($ch);
   
      
return     $lst;
   
      
14}
   
      
     $url = "http://localhost/test/post.api.php tutorial? App=test&act=testact";
   
      
     $data = Array (
   
      
'   goods_id ' => ' 1010000001224 ',
   
      
'   store_id ' => ' 20708 ',
   
      
   ' status ' => ' goodsdownshelf ',
   
      
20);
  
     

Post.api.php's Code

  
     

      
   <?php
   
      
Error_log (Var_export ($_post,1), 3, ' d:/post.txt ');
  
     

Execute the above code and generate the Post.txt file in my d:/, which reads as follows:

Array (
' goods_id ' => ' 1010000001224 ',
' store_id ' => ' 20708 ',
' Status ' => ' goodsdownshelf ',
)

Indicates that the data for the post can be obtained normally.

Code on the modification

 
     

       1 <?php 
      
 2  function api_notice_increment ($url, $data) 
      
 3 {
      
 4 $        
   ch = curl_init ();
   
      
 5 curl_setopt ($ch, curlopt_header,0);
   
      
 6 curl_setopt ($ch, Curlopt_returntransfer, 1);
   
      
 7 
      
 8 curl_setopt ($ch, Curlopt_url, $url);
   
      
 9 curl_setopt ($ch, Curlopt_post, 1);
   
      
 $data = Http_build_query ($data);
   
      
 One curl_setopt ($ch, Curlopt_postfields, $data);
   
      
 $lst [' rst '] = curl_exec ($ch);
   
      
 $lst [' info '] = curl_getinfo ($ch);
   
      
 Curl_close ($ch);
   
      
 return $lst;
   
      
} 
      
 $url = "Http://localhost/test/post.api.php?app=test&act=testact";   
      
 $data = Array (
      
 goods_id ' => ' 1010000001224 ', 
      
 ' store_id ' => ' 20708 ', 
      
 21
   ' Status ' => ' goodsdownshelf ', 
      
 22);
  
      
 
      
 
      
 Api_notice_increment ($url, $data); 
     

Just execute curl_setopt ($ch, Curlopt_postfields, $data); before executing $data = Http_build_query ($data);

Delete d:/post.txt file

Run again.

Open the D:/post.txt file again, which reads as follows:

Array (
' goods_id ' => ' 1010000001224 ',
' store_id ' => ' 20708 ',
' Status ' => ' goodsdownshelf ',
)

If you do not http_build_query the $data, the Java code will not be able to get the post data, http_build_query can be normal after the acquisition.
