401, signature_invalid, contacts matrix parameter not working

I have been trying to get the contact list of an user. As mentioned in the document, http://social.yahooapis.com/v1/user/{guid}/contacts returns first 10 contacts by default. this works fine for me.

But when I add count matrix parameter it doesn't work. it gives me 401 signature_invalid. In-fact, it doesn't work with any matrix parameter.


I am using QOAuth library in Qt 4.5.3.


When I try with the following url to get contacts:

CODE
"http://social.yahooapis.com/v1/user/VLEJ4DO33623P4PMSA2R4FEBF4/contacts"


QOAuth uses the following string as a signature base:

CODE
"GET&http%3A%2F%2Fsocial.yahooapis.com%2Fv1%2Fuser%2FVLEJ4DO33623P4PMSA2R4FEBF4%2Fcontacts&oauth_consumer_key%3Ddj0yJmk9aDlwdDBjc3pIaE1pJmQ9WVdrOVdWYzRUWHBGTldNbWNHbzlOVFl6T1RFNE16QXkmcz1jb2

Generates the following signature:

And the header looks like this:

("Authorization")


With this above header, I can get only first 10 contacts.


But when I try with matrix parameter count=20 i.e. with the URL
CODE
"http://social.yahooapis.com/v1/user/VLEJ4DO33623P4PMSA2R4FEBF4/contacts?count=20"


QOAuth uses following signature base string to generate HMAC-SHA1 signature:

    1. Matrix parameters are delimited with the semicolon, not the question mark character.
      CODE
      "http://social.yahooapis.com/v1/user/VLEJ4DO33623P4PMSA2R4FEBF4/contacts;count=20

    2. The oauth_token that you pass in the two requests are different: the first one starts with "A%3DP7", and the second one starts with "A%3D6u"
      This is strange. Unless the previous oauth_token had expired (you received an error to such an effect), you should be using the same oauth_token in both calls. Since the timestamp between these two calls shows that only a minute had elapsed, it is unlikely that the token had expired. Perhaps you have a mismatch between the oauth_token and the oauth_token_secret which is used to generate the signature in the second call?
