问题描述

有没有办法轻松使用C ++进行HTTP请求？具体来说，我想下载页面（API）的内容，并检查内容，看看它是否包含1或0.也可以将内容下载到字符串中？

Is there any way to easily make a HTTP request with C++? Specifically, I want to download the contents of a page (an API) and check the contents to see if it contains a 1 or a 0. Is it also possible to download the contents into a string?

推荐答案

我有同样的问题。 libcurl 确实完整。有一个C ++封装容器 curlpp 可能会让您感兴趣，因为您需要一个C ++库。 neon 是另一个也支持webdav的有趣的C库。

I had the same problem. libcurl is really complete. There is a C++ wrapper curlpp that might interest you as you ask for a C++ library. neon is another interesting C library that also support webdav.

curlpp似乎自然如果你使用C ++。源分发中提供了许多示例。
要获取URL的内容，你需要做这样的事情（从例子中提取）：

curlpp seems natural if you use C++. There are many examples provided in the source distribution. To get the content of an URL you do something like that (extracted from examples) :

// Edit : rewritten for cURLpp 0.7.3
// Note : namespace changed, was cURLpp in 0.7.2 ...

#include <curlpp/cURLpp.hpp>
#include <curlpp/Options.hpp>

// RAII cleanup

curlpp::Cleanup myCleanup;

// Send request and get a result.
// Here I use a shortcut to get it in a string stream ...

std::ostringstream os;
os << curlpp::options::Url(std::string("http://www.wikipedia.org"));

string asAskedInQuestion = os.str();

请参阅curlpp源分发中的 examples 目录，有很多更复杂的情况。

See the examples directory in curlpp source distribution, there is a lot of more complex cases.
