使用java代码在Glassfish服务器上请求网页

Question

正试图从java代码读取网页，并且它适用于一般网站如google.com，但是当使用相同的代码在我的计算机上阅读glassfish服务器上的页面时，我拥有此错误： -

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) 

，这是我的代码： -

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(); 
    } 

我不得不更换本地主机IP “192.120.20.167” 更改URL，但我得到这个错误

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) 

请大家帮忙， 谢谢

Answer 1

你得到505是因为你的请求参数没有编码。使用URLEncoder对您的参数进行编码，例如

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

的URL就变成

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