用于在Boost.Asio中获取HTML内容的简单界面 [英] Simple interface for getting HTML content in Boost.Asio
问题描述
有很多示例，这些示例如何向服务器发出HTTP请求并通过boost.asio库获得回复.但是，我找不到简单的界面的很好的例子，并且想知道是否需要自己实现.
There are a lot of examples how to make HTTP request to a server and get reply via boost.asio library. However, I couldn't find a good example of simple interface and wondering, if I need to implement it myself.
例如，如果我需要获取 http://的内容， www.foo.bar/path/to/default.html ，有没有办法在不验证URL的情况下获取内容，发出HTTP请求并解析服务器的答案?
For instance, if I need to get content of http://www.foo.bar/path/to/default.html, is there any way to get a content without validating URL, making HTTP request and parsing server answer?
基本上，我正在寻找这样的东西:
Basically, I am looking for something like this:
std::string str = boost::asio::get_content("http://www.foo.bar/path/to/default.html");
std::cout << str;
#
<HTML>
<BODY>
Simple HTML page!
</BODY>
</HTML>
有些事情我想避免使用boost.asio.
There are couple of things that I would like to avoid using boost.asio.
- 避免解析和验证URL.
- 手动创建HTTP请求.
- 从HTML页面内容中剪切HTTP响应.
推荐答案
从那时起，有一个新来者. C ++网络库:cpp-netlib 指出了
Since then, there is a newcomer; the C++ Network Library: cpp-netlib as pointed out here.
您想使用asio.我想您很喜欢此库的可移植性和易用性，因此 cpp-netlib 将是在那种情况下是一个很好的选择.它基于与boost相同的原理，其作者旨在将其集成到boost中.
You wanted to use asio. I suppose you fancied the portability and the ease of use of this lib, so cpp-netlib will be a great choice in that case. It is based on same principles as boost and its authors aim at integrating it into boost.
使用非常简单:
http::client client;
/*<< Creates a request using a URI supplied on the command line. >>*/
http::client::request request("http://www.foo.bar/path/to/default.html");
/*<< Gets a response from the HTTP server. >>*/
http::client::response response = client.get(request);
/*<< Prints the response body to the console. >>*/
std::cout << body(response) << std::endl;
我还没有尝试过，但是似乎可以完全满足您的需求:
I haven't tried this one but it seems to be possible to do exactly what you need:
cout << body(client().get(client::request("http://www.foo.bar/path/to/default.html")));
很久以前就问过这个问题，很抱歉把它从坟墓里挖了出来.
This question was asked a long time ago, sorry for digging it out of its grave.
