C++ Requests is a simple wrapper around libcurl inspired by the excellent Python Requests project.
Despite its name, libcurl's easy interface is anything but, and making mistakes misusing it is a common source of error and frustration. Using the more expressive language facilities of C++11, this library captures the essence of making network calls into a few concise idioms.
Here's a quick GET request:
#include <cpr.h>
int main(int argc, char** argv) {
auto r = cpr::Get(cpr::Url{"https://api.github.com/repos/whoshuu/cpr/contributors"},
cpr::Authentication{"user", "pass"},
cpr::Parameters{{"anon", "true"}, {"key", "value"}});
r.status_code; // 200
r.headers["content-type"]; // application/json; charset=utf-8
r.text; // JSON text string
}
And here's less functional, more complicated code, without cpr.
You can find the latest documentation here. It's a work in progress, but it should give you a better idea of how to use the library than the tests currently do.
C++ Requests currently supports:
- Custom headers
- Url encoded parameters
- Url encoded POST values
- Multipart form POST upload
- File POST upload
- Basic authentication
- Digest authentication
- Timeout specification
- Asynchronous requests
- ๐ช support!
- Proxy support
- Callback interface
- PUT methods
- DELETE methods
- HEAD methods
Support for the following will be forthcoming (in rough order of implementation priority):
and much more!
For just getting this library up and running, I highly recommend forking the example project. It's configured with the minimum CMake magic and boilerplate needed to start playing around with networked applications.
If you already have a project you need to integrate C++ Requests with, the primary way is to use git submodules. Add this repository as a submodule of your root repository:
git submodule add [email protected]:whoshuu/cpr.git
git submodule update --init --recursive
Next, add this subdirectory to your CMakeLists.txt before declaring any targets that might use it:
add_subdirectory(cpr)
This will produce two important CMake variables, CPR_INCLUDE_DIRS
and CPR_LIBRARIES
, which you'll use in the typical way:
include_directories(${CPR_INCLUDE_DIRS})
target_link_library(your_target_name ${CPR_LIBRARIES})
and that should do it! Using the submodule method of integrating C++ Requests, there's no need to handle libcurl yourself, all of those dependencies are taken care of for you.
The only explicit requirement is a C++11 compatible compiler such as clang or gcc. The minimum required version of gcc is unknown, so if anyone has trouble building this library with a specific version of gcc, do let me know.
This library is very much in a pre-alpha stage. Please don't attempt to use this in any serious or critical production environment. If you do use it and find bugs you'd like to report, see below!
