使用 cURL 和 PHP 检索 iTunes App Store XML [英] Retrieving iTunes App Store XML with cURL and PHP

问题描述

过去几周我一直在使用我找到并修改过的脚本从 iTunes App Store 中提取信息.一切正常，直到几天前我意识到不再生成 XML 时.这是生成 XML 的脚本的代码:

I have been extracting information from the iTunes App Store for the past couple of weeks using a script I found and modified. Everything was working fine until a couple days ago when I realized that no XML was being generated anymore. Here is the code for the script that generates the XML:

<?php
header("Content-type: text/plain"); 
ini_set('display_errors', false);

if(isset($_GET['appID']))
{
 $appID = (int)stripslashes($_GET['appID']);

 $url = "http://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=" . $appID . "&mt=8";

 $useragent = "iTunes/9.0.2 (Macintosh; Intel Mac OS X 10.5.8) AppleWebKit/531.21.8";
 $header = array("X-Apple-Store-Front: 143441-1");

 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_FAILONERROR, 1);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
 curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
 curl_setopt($ch, CURLOPT_USERAGENT, $useragent);

 $result = curl_exec($ch);

 curl_close($ch); 

 echo $result;
}
?>

所以我添加了 HTTPHEADER 选项无济于事，但更重要的是，当我进入终端并输入以下内容时，它运行得非常好:

So I added the HTTPHEADER option to no avail, but the kicker is that it works perfectly well when I go to Terminal and type this:

curl -s -A "iTunes/9.0.2 (Macintosh; Intel Mac OS X 10.5.8) AppleWebKit/531.21.8" -H "X-Apple-Store-Front: 143441-1" 'http://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=339038562&mt=8'

它返回我需要的 XML，但为什么 PHP 脚本不起作用?

It returns the XML that I need, but why won't the PHP script work?

感谢任何帮助！

推荐答案

对我来说效果很好.以下是一些需要考虑的事项:

Works fine for me. Here are few things to think about:

• 您确定设置了 $GET['appID'] 吗?也许脚本是通过 POST 运行的?
• 注释掉 ini_set('display_errors', false); 并查看是否出现任何通知/警告/错误.
• 脚本是否与 curl 命令行在同一个盒子上运行?

• Are you sure $GET['appID'] is set? Perhaps the script is being run via a POST?
• Comment out ini_set('display_errors', false); and see if any notices/warnings/errors appear.
• Is the script running on the same box as the curl command line?
