我想使用 HTTP 将“D:\er.txt”上传到网络服务器，当我运行程序时，我收到 HttpSendRequest 12005 作为错误。我在我的网络服务器上使用了一个 PHP 脚本，它将接受文件并将其存储在名为“上传”的预制目录中。这是我的小程序

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 脚本是

<?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);
}
?>

根据HttpOpenRequest的文档，lplpszAcceptTypes参数应该从

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

至

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

您还可以\0从字符串末尾删除 。您不需要手动将 nul 终止符插入到字符串文字中。

换句话说，你需要改变

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);
