使用HTTP上傳文件。 收到錯誤：-HttpSendReuest 12005

Question

我想使用HTTP將“ D：\\ er.txt”上傳到Web服務器，當我運行程序時，我收到HttpSendRequest 12005作為錯誤。 我在網絡服務器上使用了PHP腳本，它將接受該文件並將其存儲在名為“ upload”的預制目錄中。.這是我的小程序

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


    HINTERNET hConnect = InternetConnect(hSession, _T("http://jobnews.netii.net/upload.php"),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);
    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;
}

我的PHP腳本是

<?php
$uploaddir = 'upload/'; // 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);
}
?>

根據HttpOpenRequest的文檔， lplpszAcceptTypes參數應從

(const char**)"*/*\0"

至

{_T("*/*"), NULL}

您也可以從字符串末尾刪除\\0 。 您無需在字符串文字中手動插入nul終止符。

換句話說，你需要改變

HINTERNET hRequest = HttpOpenRequest(hConnect, (const char*)"POST",
                                     _T("upload.php"), NULL, NULL,
                                     (const char**)"*/*\0", 0, 1);

至

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