使用java代碼在Glassfish服務器上請求網頁

Question

正試圖從java代碼讀取網頁，並且它適用於一般網站如google.com，但是當使用相同的代碼在我的計算機上閱讀glassfish服務器上的頁面時，我擁有此錯誤： -

java.io.IOException: Server returned HTTP response code: 406 for URL: http://jedsms02:8080/Mirnint_Library-Mirnint_Message-context-root/Sending.jsp 
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1436) 
at java.net.URL.openStream(URL.java:1010) 
at reader.ReadSMS.main(ReadSMS.java:195) 

，這是我的代碼： -

String urlString = 
     "http://localhost:8080/Mirnint_Library-Mirnint_Message-context-root/Sending.jsp" 
    try { 
     URL url; 
     url = new URL(urlString);    
     Scanner in = new Scanner(url.openStream()); 
     while (in.hasNext()) 
      System.out.println(in.nextLine()); 
    } catch (MalformedURLException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

我不得不更換本地主機IP 「192.120.20.167」 更改URL，但我得到這個錯誤

java.io.IOException: Server returned HTTP response code: 505 for URL: http://192.120.20.167:8080/Mirnint_Library-Mirnint_Message-context-root/Sending.jsp?Number=0xxxxxxxxx&Message= Test Man 
at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1436) 
at java.net.URL.openStream(URL.java:1010) 
at reader.ReadSMS.main(ReadSMS.java:195) 

請大家幫忙， 謝謝

Answer 1

你得到505是因爲你的請求參數沒有編碼。使用URLEncoder對您的參數進行編碼，例如

URLEncoder.encode(" Test Man", "utf8"); 

的URL就變成

http://192.120.20.167:8080/Mirnint_Library-Mirnint_Message-context-root/Sending.jsp?Number=0xxxxxxxxx&Message=%20Test%20Man
