JSP中截获POST或GET请求提交的所有参数

这里截获POST或GET请求提交的所有请求参数,并组成查询串返回

/** *//**

*

* 该方法用于将request中参数取出组成查询串后返回

*

* @param request

* HttpServletRequest

* @return String 返回key1=value1&key2=value形式的查询串

*/

public static String getQueryString(HttpServletRequest request)...{

try...{

boolean first = true;

StringBuffer strbuf = new StringBuffer("");

Enumeration emParams = request.getParameterNames();

do ...{

if (!emParams.hasMoreElements()) ...{

break;

}

String sParam = (String) emParams.nextElement();

String[] sValues = request.getParameterValues(sParam);

String sValue = "";

for (int i = 0; i < sValues.length; i++) ...{

sValue = sValues[i];

if (sValue != null && sValue.trim().length() != 0

&& first == true) ...{

first = false;

strbuf.append(sParam).append("=").append(

URLEncoder.encode(sValue, GBK_ENCODE));

}

else if (sValue != null && sValue.trim().length() != 0

&& first == false) ...{

strbuf.append("&").append(sParam).append("=").append(

URLEncoder.encode(sValue, "GBK"));

}

}

}

while (true);

return strbuf.toString();

}catch(UnsupportedEncodingException e)...{

throw RuntimeException(e);

}

}
