Twitter4j: OAuth Consumer Key/Secret Not Set

Question

I've just started using Twitter4j and am trying to get my first application working. I've registered my application on the Twitter applications page and entered OAuth information into the twitter4j.properties file. However, every time I try to run the application I get an error message saying 'OAuth Consumer Key/Secret Not Set'. I've included the code with this message.

Any help would be greatly appreciated.

Thanks in advance, Aonghus

Answer 1

you need to create a file in the project which will look like that

debug=false
oauth.consumerKey=**************
oauth.consumerSecret=************************************
oauth.accessToken=****************************************
oauth.accessTokenSecret=*******************************

Answer 2

http://twitter4j.org/en/configuration.html

twitter4j.properties is one way.

Answer 3

您需要设置使用者密钥/秘密。您必须从Twitter Developers获得此密钥。
