OAuth Verification Failed: Verification of signature failed

[Amrit Mishra]

I am using OAuth php for my service provider and jsOAuth library for client side in iOS. 

Now when I use the oauth_token which I received with my callback url I am getting error :

OAuth Verification Failed: Verification of signature failed (signature base string was "POST&http%3A%2F%2Fapi.amishra.abc-dev.com%2Foauth%2Faccess_token.php&oauth_consumer_key%3Dab17b706d7320aa3607c8a774954eb495f7cccb3338a1f44ad4396c5a9ff69db%26oauth_nonce%3D2F4A42585632376F%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1343107528%26oauth_token%3D006d03cfc31bb7974d93ffb7cfa9001f0500e314a%26oauth_version%3D1.0").

I tried to do get request also, same.

How to fix this error.

If you log the signature base string on the client side before doing the
request, you can compare it to the signature string that is given back
in the error message.

Probably it is an encoding issue of some sorts.

cheers, Arjan
