copied!<p><strong>EDIT</strong> Where did Gaurav's answer go? :-) I believe he already answered and mentioned that you appear to be constructing a Shared Key Lite signature and should thus use "SharedKeyLite" in your authorization header.</p> <hr> <p>I think Gaurav is right in his answer, but I noticed three other issues:</p> <ol> <li>You seem to be making a call to <code>http://localhost/devstoreaccount1</code>, but you're computing a signature for <code>http://localhost/devstoreaccount1/tweet/?comp=list</code>. Make sure the URLs match up.</li> <li>For the storage emulator, I think your canonicalized resource should actually be <code>/devstoreaccount1/devstoreaccount1/tweet/?comp=list</code>. (Note the repetition of the account name.) It should generally be <code>/<account>/<path></code>, and for the storage emulator, the account name shows up in the path.</li> <li>Where's the <code>x-ms-version</code> header? I <em>believe</em> that's required.</li> </ol> <p><strong>UPDATE</strong> Here's some working code with two methods, one that uses Shared Key and one that uses Shared Key Lite. Hopefully this clears things up. Note that to use the storage emulator, you'll want to switch the URL back to <code>localhost:10000/devstoreaccount1</code>. The signature code should still work for the emulator, but I haven't tested it.
