oAuth を使用して Twitter に接続しようとしています。API https://api.twitter.com/oauth/request_tokenに POST リクエストを送信しています。
これが私の基本署名文字列の例です
POST&https%3A%2F%2Fapi.twitter.com%2Foauth%2Frequest_token&oauth_callback%3Dhttp%253A%252F%252Fapi.ec2.phunware.com%252Fapi%252Ftwitter%26oauth_consumer_key%3D6jq5dNZcccoPbApAJ0sOaA%26oauth_nonce%3DN2ZiMjViYzhlMDUxNDIyZWIwYjQ4NmU0ZjM1MDg4NTY%3D%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1362843354%26oauth_version%3D1.0
ツールhttp://quonos.nl/oauthTester/を使用して、基本署名を検証しました。
ここに対応するヘッダーがあります
OAuth oauth_callback="http%3A%2F%2Fapi.ec2.phunware.com%2Fapi%2Ftwitter",oauth_consumer_key="6jq5dNZcccoPbApAJ0sOaA",oauth_nonce="N2ZiMjViYzhlMDUxNDIyZWIwYjQ4NmU0ZjM1MDg4NTY=",oauth_signature_method="HMAC-SHA1",oauth_signature="7ney2RxElbHUl2t1Jnz57pQpmFs%3D",oauth_timestamp="1362843354",oauth_version="1.0"
MAC端末で次のコマンドを試しました
curl --request 'POST' 'https://api.twitter.com/oauth/request_token' --header 'Authorization: OAuth oauth_callback="http%3A%2F%2Fapi.ec2.phunware.com%2Fapi%2Ftwitter",oauth_consumer_key="6jq5dNZcccoPbApAJ0sOaA",oauth_nonce="N2ZiMjViYzhlMDUxNDIyZWIwYjQ4NmU0ZjM1MDg4NTY=",oauth_signature_method="HMAC-SHA1",oauth_signature="7ney2RxElbHUl2t1Jnz57pQpmFs%3D",oauth_timestamp="1362843354",oauth_version="1.0"' --verbose
そして、401の不正なエラーが発生します。oauth_callback ="oob" を設定しようとしましたが、それでも同じエラーが発生します。
助けてください。Blackberry Native SDK を使用してコーディングしています。ここにコードを貼り付けます。Blackberry 10.1 Simulator 経由で試すと、204 エラーが発生します。
