winhttp

问题 I'm trying to read a web page via WinHTTP: bool WinHTTPClass::QueryResponseData(std::string &query_data) { // Read response DWORD dwSize, dwDownloaded = 0; do { // Check for available data. if( !WinHttpQueryDataAvailable( hRequest, &dwSize ) ) { cout << "Error querying data : " << GetLastError() << endl; return false; } // Allocate space for the buffer. char* pszOutBuffer = new char[dwSize+1]; if( !pszOutBuffer ) { cout << "Out of memory" << endl; dwSize=0; } else { // Read the data.

问题 I wrote a VB6 program which uses winhttp.dll to send and receive messages to/from a remote server. It has been working fine from various operating systems: Windows 2000, WinXP, Win7, Win8. Recently the server provider informed me that they will " phase out support of SHA-1 security certificates " and i need to " check that the thumbprint is aligned to SHA-2 new SSL cert. ". What is happening now is that when my program runs on WinXP,7,8 - it's still OK. But when running on Windows 2000, when

问题 Using the Windows HTTP API I'm running a HTTP file server on localhost. This involves calling HttpAddUrl(hRequestQueue, L"http://localhost:80/", NULL) . This fails with ERROR_ACCESS_DENIED unless the user runs the application as administrator. I need this functionality for users who don't have admin privileges. (What's wrong with a user running a localhost server anyway? It's just for the user themselves.) I found a hotfix for Vista and XP which seems aimed at solving this, but there's

问题 I'm trying to save a file from https password protected site using WinHTTP. Here's the code: Sub SaveFileFromURL() Dim FileNum As Long Dim FileData() As Byte Dim WHTTP As Object fileUrl = "https://www.website.com/dir1/dir2/file.xls" filePath = "C:\myfile.xls" myuser = "username" mypass = "password" Set WHTTP = CreateObject("WinHTTP.WinHTTPrequest.5.1") WHTTP.Open "GET", fileUrl, False WHTTP.SetCredentials myuser, mypass, HTTPREQUEST_SETCREDENTIALS_FOR_SERVER WHTTP.Send FileData = WHTTP

问题 I need to be able to log the outgoing request, which I am sending using winhttp. Everything else is easy to get (status code, content, response headers, etc) but there appears to be absolutely no way to see what winhttp is actually sending in the request headers. I need to log the request headers because it contains a cookie from the login's set-cookie, but which is being rejected for unknown reasons from the application, whereas the same urls succeed in a browser. I had to convert an older

问题 I'm trying to download files(PDFs) silently from a website with VBA. So far I login without issue entering UserName & Password on the initial screen, navigate to the reports page within the site, get my list of files successfully in a table. I get the URL of the file in question without issue. Here's where I hit a wall. I do download a file but get a security warning when i open it that I must be logged in to view it. I can simulate this warning by pasting a URL into any browser when I'm not
