Windows Phone - failing to get a string from a website with login information
- by jumantyn
I am new to accessing web services with Windows Phone 7/8. I'm using a WebClient to get a string from a php-website. The site returns a JSON string but at the moment I'm just trying to put it into a TextBox as a normal string just to test if the connection works.
The php-page requires an authentication and I think that's where my code is failing. Here's my code:
WebClient client = new WebClient();
client.Credentials = new NetworkCredential("myUsername", "myPassword");
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
client.DownloadStringAsync(new Uri("https://www.mywebsite.com/ba/php/jsonstuff.php"));
void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
try
{
string data = e.Result;
this.jsonText.Text = data;
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.Message);
}
}
This returns first a WebException and then a TargetInvocationException. If I replace the Uri with for example "http://www.google.com/index.html" the jsonText TextBox gets filled with html text from Google (oddly enough, this also works even when the WebClient credentials are still set).
So is the problem in the setting of the credentials? I couldn't find any good results when searching for guides on how to access php-pages with credentials, only without them. Then I found a short mention somewhere to use the WebClient.Credentials property. But should it work some other way?
Update: here's what I can get out of the WebException (sorry for the bad formatting):
System.Net.WebException: The remote server returned an error: NotFound. ---System.Net.WebException: The remote server returned an error: NotFound.
