Reading the text from a text file on a web server [duplicate]

  • Make Https call using HttpClient

    10 answers




I used to be able to read a text file located on our public web server, into a string variable. Something has changed on the web server and now my function does not work anymore. The text file is still there and can be opened using a web browser but I cannot read it from my VB.net application



Here is the link to a sample text file: https://www.mgfx.co.za/license.txt



        Dim http As New Net.Http.HttpClient        

    Dim strWebString As String = Await http.GetStringAsync(New Uri("https://www.mgfx.co.za/license.txt"))


This does not work anymore and throws an error about authentication. "IOException: Authentication failed because the remote party has closed the transport stream."



I can only imagine that our hosting provider has implemented some sort of new security measures which now block calls from my app.



Can anyone help here or know why this is the case?

    May want to check that you're using TLS 1.2, not the default 1.1...a lot of web servers are requiring that now and I've been dealing with programs erroring because of that all year

  • Just add this line before sending the request for the first time: ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls.

  • It's really strange but the code works for me pretty well: Using client As New HttpClient : Dim x = Await client.GetStringAsync(New Uri("https://www.mgfx.co.za/license.txt")) : End Using

  • @JohnyL Maybe, you have something like this: <appSettings><add key="SecurityProtocol" value="3072" /></appSettings> or this: <add key="SecurityProtocol" value="Tls12" /> in your app.config file. There's also a registry value that can set this protocol as the default. Some applications, it happens, do this behind your back. Some developers think it's all OK, then they deploy and...

            A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

            Image
            0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
