crow - 左子网

重要的通知

不再维护。

工作叉在这里： crow CPP/ crow

crow是Web的C ++缩影。（受Python烧瓶的启发）

crow.h\”

int main()
{
crow ::SimpleApp app;

crow _ROUTE(app, \”/\”)([](){
return \”Hello world\”;
});

app.port(18080).multithreaded().run();
}\”>

# include \" crow .h \"

int main ()
{
    crow ::SimpleApp app;

    crow _ROUTE (app, \" / \" )([](){
        return \" Hello world \" ;
    });

    app. port ( 18080 ). multithreaded (). run ();
}

特征

易于路由
- 烧瓶相似
- 类型安全处理程序（请参见示例）
非常快
- 有关crow基准测试的更多数据
快速内置的JSON PARSER（ crow :: JSON）
- 您也可以使用JSON11或Rapidjson以提高速度或可读性
基于胡子的模板库（ crow ::小胡子）
仅标头
提供一个合并的标题文件crow _all.h提供每个功能（从此处下载）
中间件支持
Websocket支持

仍在开发中

~~内置ORM~~
- 如果需要，请检查SQLPP11。

例子

JSON回应

crow_ROUTE(app, \”/json\”)
([]{
crow ::json::wvalue x;
x[\”message\”] = \”Hello, World!\”;
return x;
});\”>

 crow _ROUTE (app, \" /json \" )
([]{
    crow ::json::wvalue x;
    x[ \" message \" ] = \" Hello, World! \" ;
    return x;
});

争论

crow_ROUTE(app,\”/hello/<int>\”)
([](int count){
if (count > 100)
return crow ::response(400);
std::ostringstream os;
os << count << \” bottles of beer!\”;
return crow ::response(os.str());
});\”>

 crow _ROUTE (app, \" /hello/<int> \" )
([]( int count){
    if (count > 100 )
        return crow ::response ( 400 );
    std::ostringstream os;
    os << count << \" bottles of beer! \" ;
    return crow ::response (os. str ());
});

处理程序参数类型在编译时间检查

crow_ROUTE(app,\”/another/<int>\”)
([](int a, int b){
return crow ::response(500);
});\”>

 // Compile error with message \"Handler type is mismatched with URL paramters\"
crow _ROUTE (app, \" /another/<int> \" )
([]( int a, int b){
    return crow ::response ( 500 );
});

处理JSON请求

crow_ROUTE(app, \”/add_json\”)
.methods(\”POST\”_method)
([](const crow ::request& req){
auto x = crow ::json::load(req.body);
if (!x)
return crow ::response(400);
int sum = x[\”a\”].i()+x[\”b\”].i();
std::ostringstream os;
os << sum;
return crow ::response{os.str()};
});\”>

 crow _ROUTE (app, \" /add_json \" )
.methods( \" POST \" _method)
([]( const crow ::request& req){
    auto x = crow ::json::load (req. body );
    if (!x)
        return crow ::response ( 400 );
    int sum = x[ \" a \" ]. i ()+x[ \" b \" ]. i ();
    std::ostringstream os;
    os << sum;
    return crow ::response{os. str ()};
});

如何构建

如果您只想使用crow ，请复制amalgamate/ crow _all.h并包含它。

要求

具有良好C ++ 11支持的C ++编译器（用G ++测试> = 4.8）
Boost库
构建示例的cmake
建议与TCMALLOC/JEMALLOC链接以达到速度。
现在支持功能有限的VS2013（仅提供URL的运行时间检查。）

建筑物（测试，示例）

建议使用CMAKE源代码。

mkdir build
cd build
cmake ..
make

您可以使用以下命令进行测试：

ctest

安装缺失的依赖项

Ubuntu

sudo apt-get install build-essential libtcmalloc-minimal4 && sudo ln -s /usr/lib/libtcmalloc_minimal.so.4 /usr/lib/libtcmalloc_minimal.so

OSX

brew install boost google-perftools
