好吧,在任何人得出结论之前(并且确实与我保持相关的事实),基本上,我试图做一个
使用Winsock.h 使用C / C ++中的套接字获取请求
[运行SocketRequest函数时存在的主要问题]
我从以下地方获得了错误响应代码:
" WSAENOTCONN 10057"到" WSAENOTSOCK 10038"
其中,我在此处找到了更多相关信息:https://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx
现在,这对其他人来说有点无关紧要,但更多的是我的情况。 我试图在XBOX360 Devkit上实现这个,使用" winsockx.h"当我发出一个" SocketRequest" ...这里有代码 WITH 输出以进行调试时崩溃了。 (我知道这通常不是你所看到的,所以按照你想要的方式)
此处包含的文件:
#include "stdafx.h"
#include <time.h>
#include "Hooks.h"
#include <xhttp.h>
#include <winsockx.h>
#include <iostream>
#include <xtl.h>
#include <xbdm.h>
#include <malloc.h>
#include <stdio.h>
以下是定义和实例:
int Socket;
struct sockaddr_in SocketAddress;
char bufferReturn[10000];
char serverAddr[2000];
bool returnTEST = false;
char *Request1;
char *Request2;
char *ResetRequest;
//http://www.cplusplus.com/forum/general/9403/
//http://www.cplusplus.com/forum/beginner/139313/
#define SERVER_PORT htons(80)
这里是代码(包括无法运行的SocketRequest函数):
char* SocketRequest(char* URL, char* Path = "")
{
//THIS IS THE FUNCTION THAT CRASHES WHEN IT'S CALLED IDK WHY... NOTHING IN HERE RUNS, NOT EVEN THE "prinf" STATEMENT.
printf( "Step 0");
WSADATA wsaData;
if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0) {
printf("WSA Startup FAILED! ", WSAGetLastError() );
}
printf( "Step 1");
SocketAddress.sin_addr.s_addr = htonl(INADDR_ANY);
printf( "Step 2");
SocketAddress.sin_family = AF_INET;
printf( "Step 3");
SocketAddress.sin_port = SERVER_PORT;
printf( "Step 4");
Socket = socket(AF_INET, SOCK_STREAM, 0);
printf( "Step 5");
// Make sure we have a valid socket
if( Socket == INVALID_SOCKET )
{
printf( "Attempted to send to an invalid socket.\n" );
}
printf( "Step 6");
// If we're not broadcasting, make sure we have a peer to send to
if( SocketAddress.sin_addr.s_addr == INADDR_NONE )
{
printf( "Attempted to send a non-broadcast when we have no peer.\n" );
}
printf( "Step 7");
if( bind( Socket, ( const sockaddr* )&SocketAddress, sizeof( SocketAddress ) ) != 0 )
{
printf( "Failed to bind socket, error %d.\n", WSAGetLastError() );
}
printf( "Step 8");
strcpy(serverAddr, "GET /");
if (strlen(Path) > 0){
strcat(serverAddr, Path);
}
printf( "Step 9");
strcat(serverAddr, "");
strcat(serverAddr, " HTTP/1.0\r\nHOST: ");
strcat(serverAddr, URL);
strcat(serverAddr, "\r\n\r\n");
printf( "Step 10");
char buffer[10000];
int nDataLength;
while ((nDataLength = recv(Socket, buffer, 10000, 0)) > 0){
int i = 0;
while (buffer[i] >= 32 || buffer[i] == '\n' || buffer[i] == '\r') {
cout << buffer[i];
i += 1;
printf("While_Loop1_Fail");
}
printf("While_Loop2_Fail");
}
closesocket(Socket);
return 0;
WSACleanup();
}
void ResetArray(char *array_)
{
char *begin = bufferReturn;
char *end = begin + sizeof(array_);
std::fill(begin, end, 0);
}
bool IsRequest()
{
//HERES WHERE IT CRASHES, AS **SOON** as the "Request1 = SocketRequest" line is called.
printf("is_request...");
Request1 = SocketRequest("www.mywebsite.com", "test/test.php");
if (strstr(Request1, "ON"))
{
returnTEST = true;
ResetArray(bufferReturn);
return true;
}
else if (strstr(Request1, "OFF"))
{
returnTEST = false;
ResetArray(bufferReturn);
return true;
}
else if (strstr(Request1, "Null"))
{
printf(strstr(bufferReturn, "Null\n\n"));
return false;
}
}
bool Reset()
{
ResetRequest = SocketRequest("www.mywebsite.com", "test/test.php");
printf(ResetRequest);
return true;
}
//This is where the code is ran from on the Console ON BOOT.
void mainThread(){
for(;;Sleep(45)){
if(bInitialized[0] == true || bInitialized[1] == true)
{
//THIS IS WHERE the function "IsRequest" is called.
printf("binit is true!");
if (IsRequest())
{
printf("Worked!\n");
}
}
}
}
这是输出时的输出:
binit is true! and still running...is_request...

停止代码:0x2b(PANIC_STACK_SWITCH)=当内核模式驱动程序使用过多堆栈空间时,通常会出现此错误。当内核中发生严重数据损坏时,它也会出现。 参考:https://msdn.microsoft.com/en-us/library/windows/hardware/ff557460(v=vs.85).aspx
所以,我不明白为什么它没有运行我的功能,我无法理解为什么它会崩溃。如果有人有任何想法,我将不胜感激;因为,我知道这是一个压倒性的信息主题,可能只与我的情况有关。 [我可以假设重载堆栈或char *类型的无效转换] 感谢。
答案 0 :(得分:0)
您尚未拨打connect
当然connect
需要一个远程地址,但您只有一个名字。因此,您需要通过调用gethostbyname
将名称转换为地址。
获得地址后,顺序为:
socket
创建套接字对象。bind
将连接的本地端绑定到本地地址和端口。 Bind连接你的套接字。connect
将流套接字连接到远程主机。此处您无需使用hton*
系列函数。它们用于转换您通过网络收到的号码。
备注:看起来应该合并socket
和bind
的调用,不是吗?他们不是历史的原因 - 这就是它现在的运作方式。
