在C++中,使用Boost.Asio库可以方便地进行网络编程。本文将介绍如何使用该库发送HTTP请求,包括GET和POST两种方法。首先,需要包含必要的头文件并创建I/O上下文。然后,创建一个异步的TCP套接字,用于接收服务器的响应。接着,使用boost::asio::ip::tcp::resolver和resolver获取服务器地址,然后使用connect函数连接到服务器。最后,通过write函数向服务器发送请求,并读取响应数据。
GET请求示例:
```cpp
#include
#include
intmain(){
boost::asio::io_contextio;
boost::asio::ip::tcp::resolverresolver(io);
boost::asio::ip::tcp::resolver::queryquery("www.example.com","http");
autoendpoints=resolver.resolve(query);
boost::asio::ip::tcp::socketsocket(io);
boost::asio::connect(socket,endpoints);
for(;;){
boost::asio::streambufbuf;
boost::asio::read_until(socket,buf,"\n");
std::stringresponse(buf.data(),buf.size());
std::cout<
#include
intmain(){
boost::asio::io_contextio;
boost::asio::ip::tcp::resolverresolver(io);
boost::asio::ip::tcp::resolver::queryquery("www.example.com","post");
autoendpoints=resolver.resolve(query);
boost::asio::ip::tcp::socketsocket(io);
boost::asio::connect(socket,endpoints);
for(;;){
boost::asio::streambufbuf;
boost::asio::write(socket,boost::asio::buffer(request));
std::stringresponse(buf.data(),buf.size());
std::cout<
