Poco C++——HTTP的post请求和get请求

　　两种请求都需要包含头文件：

　　#include <iostream>

　　#include <string>

　　#include "Poco/Net/HTTPClientSession.h"

　　#include "Poco/Net/HTTPRequest.h"

　　#include "Poco/Net/HTTPResponse.h"

　　#include "Poco/StreamCopier.h"

　　#include "Poco/Net/NetException.h"

　　#include "Poco/Net/HTMLForm.h"

　　#include "Poco/URI.h"

一、get请求

 try {
            URI url("https://www.baidu.com");
            HTTPClientSession session(url.getHost(),url.getPort());
            HTTPRequest req(HTTPRequest::HTTP_GET,HTTPRequest::HTTP_1_1);
            req.set("/s?word=", searhName);
            session.sendRequest(req);
            HTTPResponse res;
            istream & is = session.receiveResponse(res);
            StreamCopier::copyToString(is, result);
        }
        catch(NetException & ex){
            result = ex.displayText();
        }

二、post请求

 try{
       URI url("http://test.xheart.cn/xheartdevelop05/user/login/validate");
     HTTPClientSession session(url.getHost(),url.getPort());
     HTTPRequest request(HTTPRequest::HTTP_POST,url.getPath(),HTTPRequest::HTTP_1_1);
     HTMLForm form;
     form.add("userName", "");
     form.add("password", "");
     form.prepareSubmit(request);
     form.write(session.sendRequest(request));
     HTTPResponse res;
     std::istream & is = session.receiveResponse(res);
     StreamCopier::copyStream(is, std::cout);

 }
  catch(NetException & ex){
     std::cout << ex.displayText();
 }
