Solve the Problem of passing parameters in the URI of JSP

Java Code

2. <%!PublicString gbtoiso (string Str)
4. {Try{ByteTemp [] = Str. getbytes ("Gb2312");
6. STR =NewString (temp,ISO-8859-1");
8. ReturnSTR;
10. }Catch(Exception e ){ReturnSTR ;}}
14. Response. sendredirect (gbtoiso ("Errmsg. <SPAN class = hilite1> JSP </span>? Errmsg = customer information added"); %>

<%! Public String gbtoiso (string Str) {try {byte temp [] = Str. getbytes ("gb2312"); STR = new string (temp, "ISO-8859-1"); Return STR;} catch (exception e) {return STR ;}} response. sendredirect (gbtoiso ("errmsg.JSP? Errmsg = customer information added "); %>
 

In the hyperconnection, the priority sion isChinese

Java code

2. <A href ="Cust_totallist. <SPAN class = hilite1> JSP </span>? Action = Delete & page = <% = intcurrentpage %> & cust_id = <% = Rs. getint ("ID") %> & Amp; customization sion = <% = java.net. <SPAN class = hilite2> URL </span> encoder. encode (partition Sion ,"Iso-8859-1") %>"> Delete </a>
4. ///// // Cust_totallist. <SPAN class = hilite1> JSP </span>
6. string compression sion = java.net. class = hilite2> URL decoder. decode (request. getparameter ( " regression Sion " ). trim (), " ISO-8859-1 " );

<A href = "cust_totallist.JSP? Action = Delete & page = <% = intcurrentpage %> & cust_id = <% = Rs. getint ("ID") %> & define sion = <% = java.net.URLEncoder. encode (plugin Sion, "ISO-8859-1") %> "> Delete </a> // cust_totallist.JSPReturns the string extension sion = java.net.URLDecoder. Decode (request. getparameter ("visibility Sion"). Trim (), "ISO-8859-1 ");
 

Visible,URLEncoding format in ISO-8859-1, processingChineseJust convert the encoding format to the ISO-8859-1
Method 1:
Http://xxx.do? Ptname = 'I am a China'

Java code

1. String strptname = request. getparameter ("Ptname");
2. Strptname =NewString (strptname. getbytes (ISO-8859-1"),UTF-8");

 
String strptname = request. getparameter ("ptname"); strptname = new string (strptname. getbytes ("ISO-8859-1"), "UTF-8 ");
 

Method 2:

Java code

2. <% @ Page contenttype ="Text/html; charset = gb2312"%>
4. <A href ="Ds. <SPAN class = hilite1> JSP </span>? <SPAN class = hilite2> URL </span> = <% = java.net. <SPAN class = hilite2> URL </span> encoder. encode ("It is encoded here","Gb2312") %>"> Click here </a>
6. <%
8. // Request. setcharacterencoding ("GBK ");
10. If(Request. getparameter ("<SPAN class = hilite2> URL </span>")! =Null)
12. {
14. STR = request. getparameter ("<SPAN class = hilite2> URL </span>");
16. STR = java.net. <SpanClass= Hilite2> URL </span> decoder. Decode (STR,"Gb2312");
18. STR =NewString (Str. getbytes (ISO-8859-1"));
20. Out. Print (STR );
22. }
24. %>

<% @ Page contenttype = "text/html; charset = gb2312" %> <a href = "Ds.JSP?URL= <% = Java.net.URLEncoder. encode ("encode here", "gb2312") %> "> click here </a> <% // request. setcharacterencoding ("GBK"); If (request. getparameter ("URL")! = NULL) {STR = request. getparameter ("URL"); STR = java.net.URLDecoder. Decode (STR, "gb2312"); STR = new string (Str. getbytes ("ISO-8859-1"); Out. Print (STR);} %>
 

 

Java code

2. PublicString chinatostring (string Str)
4. {
6. String S = STR;
8. Try
10. {
12. ByteTempb [] = S. getbytes (ISO-8859-1");
14. S =NewString (tempb );
16. ReturnS;
18. }
20. Catch(Exception E)
22. {
24. ReturnS;
26. }
28. }

 
Public String chinatostring (string Str) {string S = STR; try {byte tempb [] = S. getbytes ("ISO-8859-1"); s = new string (tempb); Return s;} catch (exception e) {return s ;}}
 

 

Java code

2. Function <SpanClass= Hilite2> URL </span> encode (SSTR)
4. {
6. ReturnEscape (SSTR ).
8. Replace (/\ +/g,'% 2B').
10. Replace (/\ "/g,'% 22').
12. Replace (/\'/G ,'%27').
14. Replace (/\// G, '% 2f ');
16. }

 
FunctionURLEncode (SSTR) {return escape (SSTR ). replace (/\ +/g, '% 2B '). replace (/\ "/g, '% 22 '). replace (/\ '/g,' % 27 '). replace (// G, '% 2f ');}
 

Method 3:
If jstl is used, you can write an El function and callURLEncoder. encode.

IE default pairURLThe following parameters are not encoded, but Tomat is performed by ISO8859-1 by default.URLTherefore, the above error occurs. A good practice is:
1.URLParameters to ensure that the use of UTF-8 encoding, the method can use JS functions encodeuri (), or call the custom El function;
2. Set connector in server. XML to familiarize themselves with uriencoding = "UTF-8" to ensure that the decoding format is consistent with the encoding format;

Method 4:

XML Code

2. <Script>
4. For (VARI=0; I<Document. Links. Length; I ++ ){
6. Document. Links [I]. Href=Encodeuri(Document. Links [I]. href );
8. }
10. </Script>

<SCRIPT> for (VAR I = 0; I <document. links. length; I ++) {document. links [I]. href = encodeuri (document. links [I]. href) ;}</SCRIPT>
 

In action, string S = request. getparameter ("S ");
S = new string (S. getbytes ("iso-8859-1"), "GBK ");
