我试图通过POST请求(C ++和WINAPI),步骤,将文件发送到HTTP服务器:
// Read file into "buff" and file size into "buffSize"
....
....
....
HINTERNET internetRoot;
HINTERNET httpSession;
HINTERNET httpRequest;
internetRoot = InternetOpen(agent_info, INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, NULL);
//Connecting to the http server
httpSession = InternetConnect(internetRoot, IP,PORT_NUMBER, NULL, NULL, INTERNET_SERVICE_HTTP, NULL, NULL);
//Creating a new HTTP POST request to the default resource on the server
httpRequest = HttpOpenRequest(httpSession, TEXT("POST"), TEXT("/Post.aspx"), NULL, NULL, NULL, INTERNET_FLAG_RELOAD | INTERNET_FLAG_NO_CACHE_WRITE, NULL);
//Send POST request
HttpSendRequest(httpRequest, NULL, NULL, buff, buffSize);
//Closing handles...
在服务器我recieving使用此代码(asp.net)文件
Stream httpStream;
try
{
httpStream = request.RequestContext.HttpContext.Request.InputStream;
}
catch (HttpException)
{
return;
}
byte[] tmp = new byte[httpStream.Length];
int bytesRead = httpStream.Read(tmp, 0, 1024 * 1024);
int totalBytesRead = bytesRead;
while (bytesRead > 0)
{
bytesRead = httpStream.Read(tmp, totalBytesRead, 1024 * 1024);
totalBytesRead += bytesRead;
}
httpStream.Close();
httpStream.Dispose();
//Save "tmp" to file...
我可以将本地服务器(视觉工作室ASP服务器)上发送大文件,但我不能超过1 MB的文件发送到互联网服务器。 (HttpOpenRequest中失败)是否有更好的方式来上传文件?
