php：使用cURL获取url内容（json） [英] php: Get url content (json) with cURL

问题描述

我要访问 https://graph.facebook.com/19165649929?fields=name （显然它也可以用http访问）与cURL以获取文件的内容，更具体：我需要名称（它的json）。
因为allow_url_fopen在我的网络服务器上禁用，我不能使用get_file_contents！所以我尝试这样：

 <？php 
 $ page ='http：//graph.facebook .com / 19165649929？fields = name'; 
 $ ch = curl_init（）; 
 //$useragent=\"Mozilla/5.0（Windows; U; Windows NT 5.1; en-US; rv：1.8.1.1）Gecko / 20061204 Firefox / 2.0.0.1; 
 // curl_setopt（$ ch，CURLOPT_USERAGENT，$ useragent）; 
 curl_setopt（$ ch，CURLOPT_URL，$ page）; 
 curl_setopt（$ ch，CURLOPT_HEADER，0）; 
 curl_exec（$ ch）; 
 curl_close（$ ch）; 
？> 
  

使用该代码，我得到一个空白页面！当我使用其他网页（如 http://www.google.com ）时，它的作用就像一个魅力（我得到页面的内容）。我想Facebook是检查我不知道的东西...它可以是什么？如何使代码工作？谢谢！

解决方案

你在这里发布了吗？
php：使用cURL获取html源代码

但是在上面的线程中，我们发现你的问题beeing无法解析主机，这是解决方案：

  // $ url =https://graph.facebook.com/19165649929?fields=name; 
 $ url =https://66.220.146.224/19165649929?fields=name; 
 $ ch = curl_init（$ url）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 
 curl_setopt（$ ch，CURLOPT_BINARYTRANSFER，true）; 
 curl_setopt（$ ch，CURLOPT_SSL_VERIFYPEER，FALSE）; 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，array（'Host：graph.facebook.com'））; 
 $ output = curl_exec（$ ch）; 
 curl_close（$ ch）; 
  

I want to access https://graph.facebook.com/19165649929?fields=name (obviously it's also accessable with "http") with cURL to get the file's content, more specific: I need the "name" (it's json). Since allow_url_fopen is disabled on my webserver, I can't use get_file_contents! So I tried it this way:

<?php
$page = 'http://graph.facebook.com/19165649929?fields=name';
$ch = curl_init();
//$useragent="Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1";
//curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
curl_setopt($ch, CURLOPT_URL, $page);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
?>

With that code I get a blank page! When I use another page, like http://www.google.com it works like a charm (I get the page's content). I guess facebook is checking something I don't know... What can it be? How can I make the code work? Thanks!

解决方案

did you double post this here? php: Get html source code with cURL

however in the thread above we found your problem beeing unable to resolve the host and this was the solution:

//$url = "https://graph.facebook.com/19165649929?fields=name";
$url = "https://66.220.146.224/19165649929?fields=name";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: graph.facebook.com'));
$output = curl_exec($ch);
curl_close($ch);
