wininet

问题 I have a .NET client application that needs to communicate with a server using two distinct user credentials. Lets say that the application runs two threads. When start running, every thread sends the user & password to authenticate and the server in return stores a cookie on the http session. The subsequent calls send the authentication cookie and not the user credentials. We have two cookies for the same process. How does wininet "knows" to send the appropriate cookie for each thread? Does

问题 Note: I only want to use wininet, not urlmon-urldownloadtofile. Well, I have the following code which works perfectly in XE2 to download a file: procedure DownloadFile(URL: string; Path: string); const BLOCK_SIZE = 1024; var InetHandle: Pointer; URLHandle: Pointer; FileHandle: Cardinal; BytesRead: Cardinal; DownloadBuffer: Pointer; Buffer: array [1 .. BLOCK_SIZE] of byte; BytesWritten: Cardinal; begin InetHandle := InternetOpen(PWideChar(URL), 0, 0, 0, 0); URLHandle := InternetOpenUrl

问题 I am trying to set user name and password for proxy using InternetSetOption(...) method. However, it always returns zero and Last error is set to 12018. Below is my code snippet. #include "stdafx.h" #include <Wininet.h> int _tmain(int argc, _TCHAR* argv[]) { HINTERNET _session = ::InternetOpen(_T("TestProgram"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL); LPCTSTR proxyUserName = L"username"; LPCTSTR proxyPassword = L"userpassword"; BOOL b = ::InternetSetOption(_session,INTERNET_OPTION

问题 Let's say I have very simple little code sample which uses async WinInet: #include "stdafx.h" #include "WinInet.h" #pragma comment(lib, "wininet.lib") DWORD LatestResult = 0; HANDLE MayContinue = 0; VOID CALLBACK CallBack( __in HINTERNET hInternet, __in DWORD_PTR dwContext, __in DWORD dwInternetStatus, __in_bcount(dwStatusInformationLength) LPVOID lpvStatusInformation, __in DWORD dwStatusInformationLength ) { if (dwInternetStatus == INTERNET_STATUS_REQUEST_COMPLETE) { LatestResult = (

问题 Can anyone find problem in this function? My application makes several requests and if first request is using SSL, app crashes on some computers(on mine 4 computers + vmware it works ok without crash). Here is code char Buffer[1024]; DWORD dwRead; string data; string Request(string method, string host, string file, string headers, string post, bool debug, bool SSL) { HINTERNET hSession, hDownload, hRequest; DWORD flag; DWORD port; data.empty(); //SSL or not + flag :) if (SSL) { port =

问题 In our program, a new thread is created each time an HTTP request needs to be made, and there can be several running simultaneously. The problem I am having is that if I've got two threads already running, where they are looping on reading from InternetReadFile() after having called HttpSendRequest() , any subsequent attempts to call HttpSendRequest() just hang on that call, so I end up with the previously mentioned two threads continuing to read from their connections just fine, but the

问题 According to this answer to an earlier question of mine, the WinInet Windows API is the correct way to read and write internet connection settings in Windows. How can I use this API from Java? I'd prefer a free, open-source solution. 回答1: There's always JNI and JNA, but if you don't already know C or C++ there'll be a learning curve involved, especially with JNI: JNI Reference, JNA Site 回答2: Over the last months I had to mix with my Java project some C, C++ and Win32 alternatives for native
