Dev C++ Wininet Upload file using HTTP这里是wininet的例子。我已经改变了，但我不能让它发挥作用！首先，有警告说char函数与TCHAR varibales一起使用。我用正确的那些替换了那些功能。

#include <windows.h>
#include <wininet.h>
#include <tchar.h>
#include <iostream>

#include "stdafx.h"
#include <windows.h>
#include <wininet.h>
#include <tchar.h>
#include <iostream>

#pragma comment(lib,"wininet.lib")

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    static TCHAR frmdata[] = L"-----------------------------7d82751e2bc0858\r\nContent-Disposition: form-data; name=\"file\"; filename=\"C:\\test.txt\"\r\nContent-Type: text/plain\r\n\r\nAAAAAAAAAAAAAAAAA\r\n-----------------------------7d82751e2bc0858--\r\n";
    static TCHAR hdrs[] = L"Content-Type: multipart/form-data; boundary=---------------------------7d82751e2bc0858"; 

    HINTERNET hSession = InternetOpen(L"MyAgent",INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
     if(hSession==NULL)
    {
     cout<<"Error: InternetOpen";  
    }


    HINTERNET hConnect = InternetConnect(hSession, L"localhost",INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 1);
     if(hConnect==NULL)
    {
     cout<<"Error: InternetConnect";  
    }

    HINTERNET hRequest = HttpOpenRequest(hConnect, L"POST",L"/upload/upload.php", NULL, NULL, (LPCWSTR *)"*/*\0", 0, 1);
    if(hRequest==NULL)
    {
     cout<<"Error: HttpOpenRequest";  
    }

    BOOL sent= HttpSendRequest(hRequest, hdrs, wcslen(hdrs), frmdata, wcslen(frmdata));
    if(!sent)
    {
     cout<<"Error: HttpSendRequest";
     }

    //close any valid internet-handles
    InternetCloseHandle(hSession);
    InternetCloseHandle(hConnect);
    InternetCloseHandle(hRequest);
}

[/代码]

但它仍然无法正常工作！这就是我用netcat获得的东西

connect to [127.0.0.1] from validation.sls.microsoft.com [127.0.0.1] 52503
POST /upload/upload.php HTTP/1.1
Content-Type: multipart/form-data; boundary=---------------------------7d82751e

 C o n t e n t - D i s p o s i t i o n :   f o r m - d a t a ;   n a m e = " f
 l e " ;   f i l e n a m e = " C : \ t

我只是不明白为什么会这样。我已经改变了这个字符串

sent= HttpSendRequest(hRequest, hdrs, wcslen(hdrs), frmdata, wcslen(frmdata)*sizeof(TCHAR) );

再次使用ncat捕获数据包。它看起来像这样：

connect to [127.0.0.1] from validation.sls.microsoft.com [127.0.0.1] 52570
POST /upload/upload.php HTTP/1.1

但仍然有问题，因为我无法在upload.php脚本上上传数据（它是100％工作脚本，我用随机文件检查过它）。另外netcat中的数据看起来很奇怪，为什么字符之间有空格？也许是因为TCHAR数据？所以我仍然困惑。如何使它工作？我认为这个问题是TCHAR类型，但必须有办法让它适用于任何类型。请帮忙。也很抱歉我的英语，这不是我的母语。所有的帮助都会很有用！

对于HttpSendRequest来电，LPVOID lpOptional不应该是unicode。

试试这个：

char pszData[] = "-----------------------------7d82751e2bc0858\r\nContent-Disposition: form-data; name=\"file\"; filename=\"C:\\test.txt\"\r\nContent-Type: text/plain\r\n\r\nAAAAAAAAAAAAAAAAA\r\n-----------------------------7d82751e2bc0858--\r\n";
BOOL sent= HttpSendRequest(hRequest, hdrs, wcslen(hdrs), pszData, strlen(pszData));

Wininet上传文件TCHAR问题
