Here is my code for a mass unsubscriber I am making; currently everything works - other than the unsubscribe feature.. (Typical huh)
public void UnSubUsers()
{
string feedUrl = "http://gdata.youtube.com/feeds/api/users/" + username.Text + "/subscriptions";
YouTubeQuery query = new YouTubeQuery(feedUrl);
subFeed = service.GetSubscriptions(query);
YouTubeRequestSettings yts = new YouTubeRequestSettings("Unsubscriber", DEVKEY, username.Text, password.Text);
YouTubeRequest request = new YouTubeRequest(yts);
int i = 0;
int x = 0;
x = (listBox1.Items.Count);
for (i=0;i<x ;i++ )
{
string uname = listBox1.Items[i].ToString();
uname=uname.Substring(42);
uname = uname.Remove(uname.LastIndexOf("/"));
Subscription s = new Subscription();
s.Type = SubscriptionEntry.SubscriptionType.channel;
s.UserName = uname;
//MessageBox.Show(uname); //Displays the username so that we know if it is correct
try
{
s.AtomEntry.EditUri = "http://gdata.youtube.com/feeds/api/users/" + username.Text + "/subscriptions";
s.SubscriptionEntry.EditUri = "http://gdata.youtube.com/feeds/api/users/" + username.Text + "/subscriptions";
request.Delete(s);
}
catch (ArgumentNullException e)
{
MessageBox.Show(e.ToString(), "Error");
}
catch (GDataRequestException e)
{
MessageBox.Show(e.ToString(), "Error");
}
}
}

When the code "reaches" request.Delete(s) it gives me this error:
Google.GData.Client.GDataRequestException: Execution of request failed: http://gdata.youtube.com/feeds/api/users/iWinterHD/subscriptions --->System.Net.WebException: The remote server returned an error: (400) Bad Request.

Does anybody know how to fix this, I have been trying to get this working for around 2 hours and I am still getting this error, no matter what I try
When i used fiddler to find out info about the connection this was the header:
DELETE /feeds/api/users/iWinterHD/subscriptions HTTP/1.1
Content-Type: application/atom+xml; charset=UTF-8
User-Agent: G-Unsubscriber/GDataGAuthRequestFactory-CS-Version=2.1.0.0--IEnumerable
X-GData-Key: key=DEVELOPER_KEY

GData-Version: 2.0
Host: gdata.youtube.com

However the Google Developers example is this:
DELETE /feeds/api/users/default/subscriptions/SUBSCRIPTION_ID HTTP/1.1
Host: gdata.youtube.com
Content-Type: application/atom+xml
Authorization: Bearer ACCESS_TOKEN
GData-Version: 2
X-GData-Key: key=DEVELOPER_KEY
Hopefully that gives a little heads up :)
After searching through all the variables for around 4 hours i ended up stumbling upon the ID variable, which i later discovered needed to be passed to the final URL in order to remove the subscription WITH that ID, I tested it and it worked perfectly!
public void ListSubs()
{
string feedUrl = "http://gdata.youtube.com/feeds/api/users/" + username.Text + "/subscriptions";
YouTubeQuery query = new YouTubeQuery(feedUrl);
try
{
subFeed = service.GetSubscriptions(query);
foreach (SubscriptionEntry entry in subFeed.Entries)
{
string id = entry.Id.AbsoluteUri;
id = id.Substring(id.LastIndexOf(":")+1);
listBox1.Items.Add(id);
string usrname = entry.Content.Src.Content;
usrname = usrname.Substring(42);
usrname = usrname.Remove(usrname.LastIndexOf("/"));
listBox2.Items.Add(usrname);
}
}
catch(GDataRequestException e)
{
MessageBox.Show(e.ToString(), "Error:");
}
}
public void UnSubUsers()
{
YouTubeRequestSettings yts = new YouTubeRequestSettings("Unsubscriber", DEVELOPER_KEY, username.Text, password.Text);
YouTubeRequest request = new YouTubeRequest(yts);
int i = 0;
int x = 0;
x = (listBox1.Items.Count);
for (i=0;i<x ;i++ )
{
string uname = listBox1.Items[i].ToString();
yts = new YouTubeRequestSettings("Unsubscriber", DEVELOPER_KEY, username.Text, password.Text);
request = new YouTubeRequest(yts);
Subscription s = new Subscription();
s.Type = SubscriptionEntry.SubscriptionType.channel;
s.UserName = uname;
s.Id = listBox1.Items[i].ToString()
try
{
s.AtomEntry.EditUri = "http://gdata.youtube.com/feeds/api/users/" + username.Text + "/subscriptions" + "/" + listBox1.Items[i].ToString();
request.Delete(s);
}
catch (ArgumentNullException e)
{
}
catch (GDataRequestException e)
{
}
}
}
I had to add the subscription ID to the URL i was using to delete the subscription, here is my code to add the subscription ID to the listbox i originally used to store usernames, it turns out you can't pass usernames to the Delete method, but this works just as well because i added a second listbox to find the usernames of the subscription IDs
string id = entry.Id.AbsoluteUri;
id = id.Substring(id.LastIndexOf(":")+1);
listBox1.Items.Add(id);
This code gets the subscription ID from the entry variable, you then add the subscription ID to the EditUri variable:
s.AtomEntry.EditUri = "http://gdata.youtube.com/feeds/api/users/" + username.Text + "/subscriptions" + "/" + listBox1.Items[i].ToString();
request.Delete(s);
My mass unsubscriber is now complete!
Many thanks to @JamieDixon for all his wonderful help!
