HTTPRequest源码

# HTTPRequest HTTPRequest is a single-header C++ library for making HTTP requests. You can just include it in your project and use it. HTTPRequest was tested on macOS, Windows, Haiku, BSD, and GNU/Linux, but it should work on most of the Linux-based platforms. Supports IPv4 and IPv6. HTTRequest requires C++17 or newer. ## Usage To use the library simply include `HTTPRequest.hpp` using `#include "HTTPRequest.hpp"`. ### Example of a GET request ```cpp try { // you can pass http::InternetProtocol::V6 to Request to make an IPv6 request http::Request request{"http://test.com/test"}; // send a get request const auto response = request.send("GET"); std::cout << std::string{response.body.begin(), response.body.end()} << '\n'; // print the result } catch (const std::exception& e) { std::cerr << "Request failed, error: " << e.what() << '\n'; } ``` ### Example of a POST request with form data ```cpp try { http::Request request{"http://test.com/test"}; const string body = "foo=1&bar=baz"; const auto response = request.send("POST", body, { {"Content-Type", "application/x-www-form-urlencoded"} }); std::cout << std::string{response.body.begin(), response.body.end()} << '\n'; // print the result } catch (const std::exception& e) { std::cerr << "Request failed, error: " << e.what() << '\n'; } ``` ### Example of a POST request with a JSON body ```cpp try { http::Request request{"http://test.com/test"}; const std::string body = "{\"foo\": 1, \"bar\": \"baz\"}"; const auto response = request.send("POST", body, { {"Content-Type", "application/json"} }); std::cout << std::string{response.body.begin(), response.body.end()} << '\n'; // print the result } catch (const std::exception& e) { std::cerr << "Request failed, error: " << e.what() << '\n'; } ``` ### Example of a GET request using Basic authorization ```cpp try { http::Request request{"http://user:password@test.com/test"}; const auto response = request.send("GET"); std::cout << std::string{response.body.begin(), response.body.end()} << '\n'; // print the result } catch (const std::exception& e) { std::cerr << "Request failed, error: " << e.what() << '\n'; } ``` To set a timeout for HTTP requests, pass `std::chrono::duration` as a last parameter to `send()`. A negative duration (default) passed to `send()` disables timeout. ## License HTTPRequest is released to the Public Domain.
