php - HttpSendRequest 12005 错误

Question

我有一个小程序可以将文件上传到服务器。出于测试目的，我使用了我自己的由 WebAmp 软件创建的本地服务器。我的程序将使用 PHP 脚本上传文件，该脚本将从程序中接受文件并将它们存储到指定位置的服务器上。现在我对此感到困惑，我必须将这个 PHP 文件放在我的系统中，这样我的程序才能与这个脚本交互并成功发送文件。这是我的代码

int main()
{

    static TCHAR frmdata[] = "-----------------------------7d82751e2bc0858\r\nContent-Disposition: form-data; name=\"uploadedfile\"; filename=\"D:\\er.txt\"\r\nContent-Type: text/plain\r\n\r\nfile contents  here\r\n-----------------------------7d82751e2bc0858--\r\n";
    static TCHAR hdrs[] = "Content-Type: multipart/form-data; boundary=---------------------------7d82751e2bc0858"; 

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


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

    //HINTERNET hRequest = HttpOpenRequest(hConnect, (const char*)"POST",_T("upload.php"), NULL, NULL, (const char**)"*/*\0", 0, 1);
    LPCTSTR rgpszAcceptTypes[] = {_T("*/*"), NULL};
    HINTERNET hRequest = HttpOpenRequest(hConnect, (const char*)"POST",
                                     _T("upload.php"), NULL, NULL,
                                     rgpszAcceptTypes, 0, 1);
    if(hRequest==NULL)
    {
     cout<<"Error: HttpOpenRequest";  
    }

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


    //close any valid internet-handles
    InternetCloseHandle(hSession);
    InternetCloseHandle(hConnect);
    InternetCloseHandle(hRequest);
    getchar();
    return 0;
}

PHP脚本

<?php
$uploaddir = './'; // Relative Upload Location of data file

if (is_uploaded_file($_FILES['uploadedfile']['tmp_name'])) {
$uploadfile = $uploaddir . basename($_FILES['uploadedfile']['name']);
echo "File ". $_FILES['uploadedfile']['name'] ." uploaded successfully. ";
if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $uploadfile)) {
echo "File is valid, and was successfully moved. ";
}

else
print_r($_FILES);
}

else {
echo "Upload Failed!!!";
print_r($_FILES);
}
?>

lpszServerName 参数应该是主机名，而不是 URL。

将 http://localhost 更改为 localhost。

将此代码放在 HTTPSendRequest 下方以打印响应 header 和内容

//Print the first 2k of the response headers and content
char buffer[2048] = {};
DWORD bufferSize = sizeof(buffer);
BOOL success = HttpQueryInfo(hRequest, HTTP_QUERY_RAW_HEADERS_CRLF, buffer, &bufferSize, NULL);
if(!success)
{
    std::cout<<"Error: HttpQueryInfo "<< GetLastError();
    return 0;
}
std::cout << buffer << std::endl;

ZeroMemory(buffer, sizeof(buffer));
success = InternetReadFile(hRequest, buffer, sizeof(buffer), &bufferSize); 
if(!success)
{
    std::cout << "Error: InternetReadFile " << GetLastError();
    return 0;
}
std::cout << buffer << std::endl;
