我正在嘗試使用Tumblr的Xuath。我已經通過電子郵件發送了Tumblr支持團隊來爲我的應用程序啓用Xuath，並且他們承擔了責任。但是，在嘗試檢索用戶密鑰和密碼時，我不斷收到'400：錯誤請求'錯誤。我無法找到調試不良請求的方法。Tumblr Xauth Android - 400錯誤請求錯誤
以下是代碼：（注意 - 此代碼已被來自全國各地的網絡可用段開發）

我明白，這將是非常困難的在這裏找出確切的錯誤。但是，如果有人能夠提供建議或指引我朝着正確的方向，我會很高興。
字符串headerValue具有以下值：
的OAuth oauth_nonce = 「8d0e6e03ae2424260ddd647d5afba70d」，oauth_signature_method = 「HMAC-SHA1」，oauth_timestamp = 「1327434351943」，oauth_consumer_key = 「mdMFLrprZGnRw4XO736GXcXP8huxaxTT5z1nlxDK38GbyWlW38」，oauth_signature =「cYNStrfA％2F2lTaGKL8pxWHpzSq9w ％3D「，oauth_version =」1.0「
因此，它似乎是正確的格式。將字符串中的換行符包含在內會有幫助嗎？
