问题 I have been trying to access a URL with a / character in it from powershell, using the following command (it's a query to a gitlab server to retrieve a project called "foo/bar" ): Invoke-WebRequest https://server.com/api/v3/projects/foo%2Fbar -Verbose Now, the odd thing is that using the PowerShell ISE or Visual Studio, the request is OK. When using PowerShell itself, the URL is automatically un-escaped and the request fails. E.g. In ISE/VS: $> Invoke-WebRequest https://server.com/api/v3

问题 I was trying to use httpwebrequest to use a rest like service on a remote server and from the first execution itself, my code was hanging the program. Then I tried it as a console application to make sure it has nothing to do with the program itself but no luck! string credentialsJson = @"{""username"":""test"", ""password"":""test"" }"; int tmp = ServicePointManager.DefaultConnectionLimit; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(@"https://qrua.com/qr/service" + @"/auth

问题 I have a silverlight 4 application using the ClientHttp stack to make a WebRequest which serves a binary stream. I then read from this stream and do stuff.

问题 I have a web api I need to use. This api will return the data according the content type I'm sending. Normally it will return html response. If the request has Content-Type header with the 'application/json' header it will return a json response. When I try it using Postman and adding the content-type header (as application/json) everything is good. But when trying it using C# WebRequest object I'm always getting the html response regardless the content-type header I'm using. I've used

问题 I'm trying to use webRequest API to change the loaded .swf file on a webpage... The page loads a file called chat.swf, but i want to redirect to chat2.swf in the same directory in order to use the other file. I was told that this could work, but I have no idea how to use this API correctly and I cannot find any examples @_@ function incerceptChat(chat){ console.log( "onBeforeRequest", details ); if(chat.url == swf1){ chat = swf2; } } that's my function that's supposed to change the URL, but I

问题 We have a servlet that will deliver PDF reports to a browser. We also have a IIS server running .net apps and we want to return the PDF from the servlet as a stream to the .Net app and then the .Net app would render the PDF to the browser (we are using this technique for reason I don't need to go into here). I am not much of a VB/ Visual Studio devloper by this code works by using a web request: Dim BUFFER_SIZE As Integer = 1024 ' Create a request for the URL. Dim serveraction As String =
