Java程序調用REST服務需要認證

     URLConnection connection = url.openConnection(); 
     connection.setDoOutput(true); 

     String encodedCredentials = new String(

      BufferedReader in = new BufferedReader(new InputStreamReader(
        connection.getInputStream()));

REST Service Invoked Successfully..

誰能幫我解決這個問題。如果在REST客戶端廣告中使用此鏈接，那麼這個鏈接工作得非常好。但是，對於這個Java程序，它會拋出302錯誤。

服務器響應重定向。如果你想用'url.openConnection（）'自己實現它，你必須編寫代碼來處理它 - 或者使用類似apache httpclient的東西，這使得它更容易：http://hc.apache.org /httpclient-3.x/順便說一句：302不是錯誤！ – Alexander 2015-04-01 07:39:37

好吧..我也嘗試過使用HttpClient，但也有身份驗證沒有發生，並將401身份驗證失敗作爲響應。你能幫我解決這個問題嗎？ – user3564975 2015-04-03 06:34:26

我在嘗試類似的東西時遇到了你的線程。對我來說，通過將「Basic」與encodedCredentials變量連接在一起解決了問題，使其成爲「Basic EncodedValue」。
