httprequest's Introduction

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:[email protected]/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.

Tons of errors when including

Hi, so I just included the file in my project like this: #include "HTTPRequest.hpp", and I get all these errors during compilation:

Error C2664 in HTTPRequest.hpp file

Within file HTTPRequest.hpp, line 379, we get error C2664.
Changing the line to std::unique_ptr<addrinfo, void(__stdcall*)(addrinfo*)> addressInfo(info, freeaddrinfo); seems to fix the issue.

Json post bug

I built a request using nlohmann:: JSON and wrote the code according to the example, but I encountered the following bug:

terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_S_create
Aborted

You should use a JSON library like https://github.com/nlohmann/json for JSON encoding. JSON is not a part of the HTTP standard (RFC 7231) so it is out of the scope of this library. I added an example on hot wo send a JSON POST in b6b8795.

Slow performance on Windows 10

I can install and compile your code very easily, but for some reason a simple GET to a localhost server takes upwards of 20 seconds, whereas it is instant in firefox. Is there a Windows firewall setting or something that may be causing this?

argument of type "uint8_t " is incompatible with parameter of type "const char " HTTPRequest.hpp line 454

Hello, first i would like to thank you for producing such useful thing. However i have a problem as detailed below. Thanks in advance.

Line 454:
const auto size = ::send(socket, requestData.data() + sent, static_cast<size_t>(remaining), flags);

second parameter of ::send() [requestData.data()] is the problem according to Visual Studio 2019 (version 16.4.4) on Windows10. Any suggestions?

Send header

How can i send a header in a get or post request?

Is it support to send JSON POST Request?

Is it support to send JSON POST Request? and how to send JSON POST Request?

Linking error

Hey, I'm kinda new to C++, and I've been trying to include your .hpp file in my project and it gave me these linking errors:
I've included the file in the project and the IDE recognizes it, but It gives these linking errors when I try to build it.
Do you have any tips to fix this issue?

Wont compile

just tells me this:

Response empty

Hello,

I am making a call to the imgflip API but when I make that call, although there are no errors, the response is empty. Trying to print the response yields nothing and printing the response.body.size() outputs a value of zero.

send Variable GET Request

How can i send a variable GET Request?
http::Request request{ Variable };

Is there a plan to support https ?

Post request failed

Idk what´s wrong here, but the post request failed.
For example if I use another lib like restclient-cpp it`s working fine.
But libcurl is hughe that´s why I want to switch to a header only.

Here is the code ->
http::Request request("https://api.tarkov.dev/graphql"); const auto parameters = (xorstr_( "{\"operationName\":null,\"variables\":{},\"query\":\"{\\n items: itemsByType(type: any) {\\n id\\n name\\n avg24hPrice\\n width\\n height\\n }\\n}\\n\"}")); const auto response = request.send("POST", parameters, {"Content-Type: application/json"});

Windows10 Runtime Get Error

Hello, i noticed that when running this test code:

    http::Request request("http://test.com/test");
    // send a get request
    http::Response response = request.send("GET");
    std::cout << response.body.data() << std::endl; // print the result

It gets an error in HtppRequest.h line 401.
I fixed it with putting this code right before line 401:

      WSADATA wsaData;
      int error = WSAStartup(MAKEWORD(2, 2), &wsaData);
      if (error != 0)
        	throw std::system_error(error, std::system_category(), "WSAStartup failed");

now everything seems to work

can it support https ?

my website has ssl and i really need it

Timeout not implementable

I just want to understand what i am doing wrong :/

string webRequest(std::string path)
{
try
{
http::Request request{ serverUrl + path };
const auto response = request.send("GET", std::chrono::seconds(2)); // <--- Error pointed (When i remove the chrono, it works but the request never get any timeout, so never catched
std::cout << "RESPONSe : " << response.status;
return std::string{ response.body.begin(), response.body.end() };
}
catch (const std::exception& e) {
std::cout << e.what();
return ""; // Failed, don't crash but return no response.
}
}

Error (active) E0304 no instance of overloaded function "http::Request::send" matches the argument list

I tried a lot of solutions like including windows.h before httprequest.cpp but nothing works

Need to specify port in request header!

When I used the method "POST" and an address with port number 8080. I always got an 502 bad gateway error. After using wireshark and compare the c++ post request with the curl post request, I found that in the header you need to concatenate the port number after the domain! In the original implementation, the header string just contains a domain there.

I am not a native speaker, and any discussion is welcomed. I'll start a pull request later time.

is this a prank repo?

Message headers are case-insensitive

According to RFC 2616 the Message Headers are case-insensitive (stated as: "Field names are case-insensitive"). However, your code is checking for "Content-Length" and "Transfer-Encoding" in a case sensitive manner so it does not process the response for some web servers. Any chance this can be modified? If a PR is better I can provide one.

Implement support for timeout specification

For the application I'm working on it would be useful to be able to specify the connection and send/recv timeout.

This could be implemented as an extra optional argument to relevant methods (e.g. Request::send()), as a connection-wide option to the Request() constructor, or something else.

Usable for VS 2017?

invalid or corrupt file

[Visual Studio 2019]
Hi,
when I try #include "HTTPRequest.hpp" and then try to compile I get the error "Invalid or corrupt file: cannot read at 0x5F48". I can see the file in the solution explorer and added it to the additional dependencies in the linker. The Microsoft-Docs say to recreate the file, but even that didn't help.
Sorry if I am just forgetting something but I am a bit new to c++.

Responses

Sorry for a brain dead question:
After posting to my PHP webpage, how would I get the ‘echo’ response to my c++ client?

Thanks in advance.

Does it support C++11?

I got a bunch of errors trying to compile it. test/Makefile says its c++17. Just to make sure, does it support 11 or am i missing something??

If it doesn't, you should write supported versions in README

Usable to Visual Studio 2013?

I think its broken

Will you add support for HTTPS?

Just add HTTPS
