Question

我正在寻找实现或启用 HTTP 客户端实现的 ac/C++ 库。它也应该支持 http1.1 和 ssl。你会提出什么建议？

提前感谢您的宝贵时间。

Answer 1

libcurl支持 HTTP1.1、TLS，并且似乎在类似于 BSD 的许可下：

Answer 2

Beast 支持 HTTP/1.0 和 HTTP/1.1，它适用于 Boost.Asio 常规套接字或 SSL 流。它是 Boost 的一部分，包含大量文档，并基于 gcc、clang 和 Visual Studio 构建！https://github.com/boostorg/beast/

这是一个完整的示例程序：使用 HTTP 从网站请求根页面并打印响应：

#include <beast/http.hpp>
#include <boost/asio.hpp>
#include <iostream>
#include <string>

int main()
{
    // Normal boost::asio setup
    std::string const host = "boost.org";
    boost::asio::io_service ios;
    boost::asio::ip::tcp::resolver r(ios);
    boost::asio::ip::tcp::socket sock(ios);
    boost::asio::connect(sock,
        r.resolve(boost::asio::ip::tcp::resolver::query{host, "http"}));

    // Send HTTP request using beast
    beast::http::request_v1<beast::http::empty_body> req;
    req.method = "GET";
    req.url = "/";
    req.version = 11;
    req.headers.replace("Host", host + ":" + std::to_string(sock.remote_endpoint().port()));
    req.headers.replace("User-Agent", "Beast");
    beast::http::prepare(req);
    beast::http::write(sock, req);

    // Receive and print HTTP response using beast
    beast::streambuf sb;
    beast::http::response_v1<beast::http::streambuf_body> resp;
    beast::http::read(sock, sb, resp);
    std::cout << resp;
}
