Hey Alvin, Your URL looks badly formed as it includes .../home_timeline.json?&count=5.... I would expect to see .../home_timeline.json?count=5... (so no & after the ?). You also have realm in your query string when it isn't needed. Realm is optional and when used, is only used in the Authorization header. When using OAuth in the query string you shouldn't pass realm. Your parameters should also be in lexicographical order.
In your case I would have expected your URL to look like this: http://api.twitter.com/1/statuses/home_timeline.json?count=5&oauth_consumer_key=.......&oauth_nonce=.....&oauth_signature=......&oauth_signature_method=HMAC-SHA1&oauth_timestamp=......&oauth_version=1.0 &page=1 You can read more about signing requests on our developer resources site: http://dev.twitter.com/pages/auth#signing-requests Best @themattharris Developer Advocate, Twitter http://twitter.com/themattharris 2010/11/23 Alvin Wang <alvin0...@gmail.com> > hello Matt, > here is the image when 401 occurs. > > http://dl.dropbox.com/u/162763/1.png > > On 11月23日, 下午2時17分, Matt Harris <thematthar...@twitter.com> wrote: > > Hey Alvin, > > > > So the community and developers can help you we'll need to know a little > bit > > more about the error you are receiving.
