C＃HttpRequest发布URL

Question

I'm trying to get an HttpRequest to post this URL

https://www.iformbuilder.com/exzact/_emptyTable.php?PAGE_ID=1234&TABLE_NAME=table_name_here&USERNAME=yo@yo.com&PASSWORD=What!What !

I've tried using

WebClient rar = new WebClient();
rar.OpenReadAsync(new Uri(@"https://www.iformbuilder.com/exzact/_emptyTable.php?PAGE_ID=1234&TABLE_NAME=table_name_here&USERNAME=yo@yo.com&PASSWORD=What!What!"));

rar.DownloadStringAsync(new Uri(@"https://www.iformbuilder.com/exzact/_emptyTable.php?PAGE_ID=1234&TABLE_NAME=table_name_here&USERNAME=yo@yo.com&PASSWORD=What!What!"));

This is suppose to delete my information on their site, but it's not taking. i'm following this documentation. http://getsatisfaction.com/exzact/topics/how_can_we_delete_old_records_not_manually

and they state that all I have to do is paste the proper URL into a web browser and hit enter and it will work. How would I do this equivalent in c#? Any help would be awesome! Thanks!

Answer 1

Use WebClient.DownloadString instead of DownloadStringAsync. Async indicates asynchronous methods that do not block the current thread.

Answer 2

Try setting your User-Agent header in your WebClient before you submit it to see if that fixes things.

rar.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)")

A lot of web servers are set up to simply ignore requests if the User-Agent header is missing.

Subsequently, you're using HTTPS here so you'll want to set up your ServicePointManager.ServerCertificateValidationCallback as well.

Try to use System.Web classes, for example like this:

        HttpWebRequest req = null;
        HttpWebResponse resp = null;

        try
        {
            req = (HttpWebRequest)HttpWebRequest.Create(url); // enter your url

            req.Method = "post";

            resp = (HttpWebResponse)req.GetResponse();
        }
        catch (Exception)
        {
            throw;
        }

It's example for post method, you can use any other HTTP method like this. Check the documentation .

  string uriString = @"https://www.iformbuilder.com/exzact/_emptyTable.php?PAGE_ID=1234&TABLE_NAME=table_name_here&USERNAME=yo@yo.com&PASSWORD=What!What!"; using (WebClient webClient = new WebClient { Encoding = Encoding.UTF8 }) { try { string content = webClient.DownloadString(uriString); //do stuff with the answer you got back from the site } catch (Exception exception) { //handle exceptions } }
