如何从C ++的互联网下载xml [英] How do I download xml from the internet in C++
问题描述
当您将网页另存为.xml或查看网页来源时，与浏览器做同样的事情。当然，我的目标是使用xml的网页，并且像这样开始：
<？xml version =1.0编码= UTF-8 >？;
<！DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional。 DTD>
为什么我要这么做？那么我想将某些网页的整个源代码转储为字符串或CString，我仍然是搞清楚如何做 既然你提到了Visual C ++，一个好的解决方案就是利用最近发布的来自Microsoft Research的HTTP Casablanca库，前提是你也可以使用C ++ 11。

您需要使用HTTP客户端，与本教程中描述的类似，
http://msdn.microsoft.com/en-US/devlabs/hh977106.aspx
可以是类似的，
http_client客户端（L HTTP：// somewebs ite.com）;
client.request（methods :: GET，Lpage-to-download.html）
.then（[]（http_response response）{
cout<<< ;HTML SOURCE：<< endl<<< response.to_string（）<< endl;}）
.wait（）;
The same way an internet browser does it when you save page as .xml, or view page source. Of course I am targeting a webpage that is in xml and starts like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Why do I want to do this? Well I want to dump the entire source of certain webpages into a string or CString, which I'm still figuring out how to do
Since you mentioned Visual C++, a good solution would be to make use of the recently published HTTP Casablanca library from Microsoft Research, provided you are able to use C++11 as well.

The you need to make use of a HTTP client, similar to what is described in this tutorial, http://msdn.microsoft.com/en-US/devlabs/hh977106.aspx
Which can be something like,
http_client client( L"http://somewebsite.com" );
client.request( methods::GET, L"page-to-download.html" )
.then( []( http_response response ) {
cout << "HTML SOURCE:" << endl << response.to_string() << endl; })
.wait();
