Build

Requirement

• workflow, version v0.9.9 or newer
• Linux , like ubuntu 16.04 or newer
• Cmake or Xmake
• zlib1g-dev
• libssl-dev
• libgtest-dev
• gcc and g++ or llvm + clang, tested with ubuntu 20.04

Tips : Because in g++ 4.9 and the previous version, lambda can't capture variadic templates, we require you to upgrade your g++ version to 5.0 and above.

If you are on ubuntu 20.04, you may install them by command:

apt-get install build-essential cmake zlib1g-dev libssl-dev libgtest-dev -y

For more details, you can see here : requirement details

Cmake

git clone --recursive https://github.com/wfrest/wfrest
cd wfrest
make
sudo make install

For test :

make check

For example :

make example

Xmake

If you want to use xmake to build wfrest, you can see xmake build document

Docker

Use dockerfile, the Dockerfile locate /docker subdirectory of root source code repository.

docker build -t wfrest ./docker/ubuntu/

If you are using podman, you can also build it. and tested under ubuntu 20.04

podman build -t wfrest ./docker/ubuntu/

Or you can Pull from DockerHub

docker pull wfrest/wfrest

Quick start

#include "wfrest/HttpServer.h"
using namespace wfrest;

int main()
{
    HttpServer svr;

    // curl -v http://ip:port/hello
    svr.GET("/hello", [](const HttpReq *req, HttpResp *resp)
    {
        resp->String("world\n");
    });
    // curl -v http://ip:port/data
    svr.GET("/data", [](const HttpReq *req, HttpResp *resp)
    {
        std::string str = "Hello world";
        resp->String(std::move(str));
    });

    // curl -v http://ip:port/post -d 'post hello world'
    svr.POST("/post", [](const HttpReq *req, HttpResp *resp)
    {
        // reference, no copy here
        std::string& body = req->body();
        fprintf(stderr, "post data : %s\n", body.c_str());
    });

    if (svr.start(8888) == 0)
    {
        getchar();
        svr.stop();
    } else
    {
        fprintf(stderr, "Cannot start server");
        exit(1);
    }
    return 0;
}
