我对C++很陌生。最近,我试图通过post方法将一些数据传递给c++中的php文件。我已经尝试过MSDN send Function的教程。代码如下:
#ifndef UNICODE
#define UNICODE
#endif
#define WIN32_LEAN_AND_MEAN
#include <winsock2.h>
#include <Ws2tcpip.h>
#include <stdio.h>
#include <conio.h>
// Link with ws2_32.lib
#pragma comment(lib, "Ws2_32.lib")
#define DEFAULT_BUFLEN 512
#define DEFAULT_PORT 27015
int main() {
//----------------------
// Declare and initialize variables.
int iResult;
WSADATA wsaData;
struct hostent *host;
SOCKET ConnectSocket = INVALID_SOCKET;
struct sockaddr_in clientService;
int recvbuflen = DEFAULT_BUFLEN;
char *sendbuf = "Client: sending data test";
char recvbuf[DEFAULT_BUFLEN] = "";
//----------------------
// Initialize Winsock
iResult = WSAStartup(MAKEWORD(2,2), &wsaData);
if (iResult != NO_ERROR) {
wprintf(L"WSAStartup failed with error: %d\n", iResult);
return 1;
}
//----------------------
// Create a SOCKET for connecting to server
ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (ConnectSocket == INVALID_SOCKET) {
wprintf(L"socket failed with error: %ld\n", WSAGetLastError());
WSACleanup();
return 1;
}
//----------------------
// The sockaddr_in structure specifies the address family,
// IP address, and port of the server to be connected to.
clientService.sin_family = AF_INET;
clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );
clientService.sin_port = htons( 80 );
//----------------------
// Connect to server.
iResult = connect( ConnectSocket, (SOCKADDR*) &clientService, sizeof(clientService) );
if (iResult == SOCKET_ERROR) {
wprintf(L"connect failed with error: %d\n", WSAGetLastError() );
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
//----------------------
// Send an initial buffer
iResult = send( ConnectSocket, sendbuf, (int)strlen(sendbuf), 0 );
if (iResult == SOCKET_ERROR) {
wprintf(L"send failed with error: %d\n", WSAGetLastError());
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
printf("Bytes Sent: %d\n", iResult);
// shutdown the connection since no more data will be sent
iResult = shutdown(ConnectSocket, SD_SEND);
if (iResult == SOCKET_ERROR) {
wprintf(L"shutdown failed with error: %d\n", WSAGetLastError());
closesocket(ConnectSocket);
WSACleanup();
return 1;
}
// Receive until the peer closes the connection
do {
iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
if ( iResult > 0 )
wprintf(L"Bytes received: %d\n", iResult);
else if ( iResult == 0 )
wprintf(L"Connection closed\n");
else
wprintf(L"recv failed with error: %d\n", WSAGetLastError());
} while( iResult > 0 );
// close the socket
iResult = closesocket(ConnectSocket);
if (iResult == SOCKET_ERROR) {
wprintf(L"close failed with error: %d\n", WSAGetLastError());
WSACleanup();
return 1;
}
WSACleanup();
getch();
}
它将数据发送到localhost的主页,但我想将数据发送到localhost的其他位置(例如,像'localhost / test / index.php')。如果我将代码从
clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );
更改为clientService.sin_addr.s_addr = inet_addr( "127.0.0.1/test/index.php" );
,那么我在exe文件中收到一些错误。但是程序成功编译。请给我一个解决方案。我现在应该怎么办?
最佳答案
您采用了错误的方法。低级套接字层仅允许您连接到特定服务器(例如,运行在127.0.0.1上的本地http服务器在端口80上侦听)并发送原始数据。您需要与该服务器进行HTTP对话才能真正完成您想做的事情。
我建议,如果您是C++的新手,请查看C++的许多第三方库之一,该库允许您与http服务器“对话HTTP”-例如libCurl
