fcgi

c ++ {#mainpage}中的FastCGI实现

dmitigr:: fcgi是用C ++编写的FASTCGI协议实现。

你好世界

fcgi .hpp>
#include <iostream>

int main()
{
namespace fcgi = dmitigr:: fcgi ;
try {
const auto port = 9000;
const auto backlog = 64;
fcgi ::Listener server{ fcgi ::Listener_options{"0.0.0.0", port, backlog}};
server.listen();
while (true) {
if (const auto conn = server.accept()) {
conn->out() << "Content-Type: text/plain" << fcgi ::crlfcrlf;
conn->out() << "Hello from dmitigr:: fcgi !";
}
}
} catch (const std::exception& e) {
std::cerr << "Oops: " << e.what() << std::endl;
return 1;
}
}\”>

# include < dmitigr/ fcgi / fcgi .hpp >
# include < iostream >

int main ()
{
  namespace fcgi = dmitigr:: fcgi ;
  try {
    const auto port = 9000 ;
    const auto backlog = 64 ;
    fcgi ::Listener server{ fcgi ::Listener_options{ \" 0.0.0.0 \" , port, backlog}};
    server. listen ();
    while ( true ) {
      if ( const auto conn = server. accept ()) {
        conn-> out () << \" Content-Type: text/plain \" << fcgi ::crlfcrlf;
        conn-> out () << \" Hello from dmitigr:: fcgi ! \" ;
      }
    }
  } catch ( const std::exception& e) {
    std::cerr << \" Oops: \" << e. what () << std::endl;
    return 1 ;
  }
}

您好，多线程世界

fcgi .hpp>
#include <iostream>
#include <thread>
#include <vector>

namespace {

constexpr std::size_t pool_size{64};

} // namespace

int main()
{
namespace fcgi = dmitigr:: fcgi ;
try {
const auto serve = [](auto* const server)
{
while (true) {
const auto conn = server->accept();
conn->out() << "Content-Type: text/plain" << fcgi ::crlfcrlf;
conn->out() << "Hello from dmitigr:: fcgi !";
conn->close(); // Optional.
}
};

const auto port = 9000;
const auto backlog = 64;
std::clog << "Multi-threaded FastCGI server started:\\n"
<< " port = " << port << "\\n"
<< " backlog = " << backlog << "\\n"
<< " thread pool size = " << pool_size << std::endl;

fcgi ::Listener server{ fcgi ::Listener_options{"0.0.0.0", port, backlog}};
server.listen();
std::vector<std::thread> threads(pool_size);
for (auto& t : threads)
t = std::thread{serve, &server};

for (auto& t : threads)
t.join();

server.close(); // Optional.
} catch (const std::exception& e) {
std::cerr << "error: " << e.what() << std::endl;
return 1;
}
}\”>

# include < dmitigr/ fcgi / fcgi .hpp >
# include < iostream >
# include < thread >
# include < vector >

namespace {

constexpr std:: size_t pool_size{ 64 };

} // namespace

int main ()
{
  namespace fcgi = dmitigr:: fcgi ;
  try {
    const auto serve = []( auto * const server)
    {
      while ( true ) {
        const auto conn = server-> accept ();
        conn-> out () << \" Content-Type: text/plain \" << fcgi ::crlfcrlf;
        conn-> out () << \" Hello from dmitigr:: fcgi ! \" ;
        conn-> close (); // Optional.
      }
    };

    const auto port = 9000 ;
    const auto backlog = 64 ;
    std::clog << \" Multi-threaded FastCGI server started: \\n \"

      t = std::thread{serve, &server};

    for ( auto & t : threads)
      t. join ();

    server. close (); // Optional.
  } catch ( const std::exception& e) {
    std::cerr << \" error: \" << e. what () << std::endl;

用法

快速用作仅标题库

将src目录的内容复制到一个项目目录，该目录包括编译器的路径，例如src/3rdparty/dmitigr 。

创建hello.cpp ：

fcgi .hpp"

int main()
{
// Application code here…
}\”>

# include \" dmitigr/ fcgi / fcgi .hpp \"

int main ()
{
  // Application code here...
}

编译hello.cpp ：

 g++ -std=c++17 -ohello hello.cpp

用cmake快速使用

创建构建目录，配置，构建和安装：

fcgi
mkdir build && cd build
cmake ..
cmake –build .
sudo cmake –install .\”>

 cd fcgi
mkdir build && cd build
cmake ..
cmake --build .
sudo cmake --install .

创建hello/hello.cpp ：

fcgi .hpp"

int main()
{
// Application code here…
}\”>

# include \" dmitigr/ fcgi / fcgi .hpp \"

int main ()
{
  // Application code here...
}

创建hello/CMakeLists.txt ：

fcgi)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
add_executable(hello hello.cpp)
target_link_libraries(hello dmitigr_ fcgi )\”>

 cmake_minimum_required ( VERSION 3.16 )
project ( foo )
find_package ( dmitigr_cpplipa REQUIRED COMPONENTS fcgi )
set ( CMAKE_CXX_STANDARD 17 )
set ( CMAKE_CXX_STANDARD_REQUIRED ON )
add_executable ( hello hello.cpp )
target_link_libraries ( hello dmitigr_ fcgi )

编译hello/hello.cpp ：

 mkdir hello/build && cd hello/build
cmake ..
cmake --build .
