README
C++ Requests: Curl for People
Announcements
The cpr project has new maintainers: Fabian Sauter and Tim Stack.
TLDR
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/cpr.h>
int main(int argc, char** argv) {
cpr::Response 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.header["content-type"]; // application/json; charset=utf-8
r.text; // JSON text string
}
And here's less functional, more complicated code, without cpr.
Documentation
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.
Features
C++ Requests currently supports:
- Custom headers
- Url encoded parameters
- Url encoded POST values
- Multipart form POST upload
- File POST upload
- Basic authentication
- Bearer authentication
- Digest authentication
- NTLM authentication
- Connection and request timeout specification
- Timeout for low speed connection
- Asynchronous requests
- :cookie: support!
- Proxy support
- Callback interfaces
- PUT methods
- DELETE methods
- HEAD methods
- OPTIONS methods
- PATCH methods
- Thread Safe access to libCurl
- OpenSSL and WinSSL support for HTTPS requests

Usage
If you already have a project you need to integrate C++ Requests with, the primary way is to use CMake fetch_content
.
Add the following to your CMakeLists.txt
.
include(FetchContent)
FetchContent_Declare(cpr GIT_REPOSITORY https://github.com/whoshuu/cpr.git GIT_TAG c8d33915dbd88ad6c92b258869b03aba06587ff9) # the commit hash for 1.5.0
FetchContent_MakeAvailable(cpr)
This will produce the target cpr::cpr
which you can link against the typical way:
target_link_libraries(your_target_name PRIVATE cpr::cpr)
That should do it!
There's no need to handle libcurl
yourself. All dependencies are taken care of for you.
Requirements
The only explicit requirements are:
- 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 - If you would like to perform https requests
OpenSSL
and its development libraries are required.
Building cpr - Using vcpkg
You can download and install cpr using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install cpr
The cpr
port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.
Building cpr - Using Conan
You can download and install cpr
using the Conan package manager. Setup your CMakeLists.txt (see Conan documentation on how to use MSBuild, Meson and others) like this:
project(myproject CXX)
add_executable(${PROJECT_NAME} main.cpp)
include(${CMAKE_BINARY_DIR}/conanbuildinfo.cmake) # Include Conan-generated file
conan_basic_setup(TARGETS) # Introduce Conan-generated targets
target_link_libraries(${PROJECT_NAME} CONAN_PKG::cpr)
Create conanfile.txt
in your source dir:
[requires]
cpr/1.5.0
[generators]
cmake
Install and run Conan, then build your project as always:
pip install conan
mkdir build
cd build
conan install ../ --build=missing
cmake ../
cmake --build .
The cpr
package in Conan is kept up to date by Conan contributors. If the version is out of date, please create an issue or pull request on the conan-center-index
repository.
