C++ httplib创建http服务

创建post接口

说明

使用C++ 的 httplib创建http服务，演示了一个创建了post接口的函数。包含日志模块
具体的逻辑代码没有贴进来，根据需求实现

main.cpp

#include "http/httplib.h"
#include "http/detect.hpp"
#include "ocr/ocr.hpp"
#include "http/serverLog.hpp"                                                                                                                                                                                    
#include "plog/Log.h"
#include "plog/Initializers/RollingFileInitializer.h"
#include <csignal>

void signalHandler( int signum )
{
    PLOGW << "Shut down http server";
    exit(signum);
}


int main() 
{
    signal(SIGINT, signalHandler); 
    plog::init(plog::info, "ocr_match.log", 10000000, 2); 
    
    ocr::TemplateOcr tocr;
    
    httplib::Server svr;
    PLOGI << "Start server";

    svr.set_logger(server_logger);

    svr.Post("/ocr/structed", [&](const httplib::Request& req, httplib::Response& res) {
        {   
            PLOGI << "Receive request";
            detect(req, res, tocr);
            PLOGI << "End request";
        }   
    }); 


    PLOGI << "Server listen on 8000";
    svr.listen("0.0.0.0", 8000);

    return 0;
}

            + std::to_string(res.status) 
            + std::string(" ") 
            + std::string(httplib::detail::status_message(res.status)) 
            + std::string("\033[0m");
    }   
    else
    {   
        line = std::string("\033[31m") 
            + std::to_string(res.status)

    }   
    PLOGI << req.remote_addr << ":" 
        << req.remote_port << " - "
        << "\"" << req.method << " " 
        << req.path << " " 
        << res.version << "\" "
        << line;

}

具体的实现放在detect函数里面，将入参和出参全部传入。
