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. HTTPRequest requires C++17 or newer.

Usage

To use the library simply include HTTPRequest.hpp using #include "HTTPRequest.hpp".

Example of a GET request

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

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

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

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.
