Jsp格式编码 [英] Jsp form encoding

问题描述

我有一个jsp页面（让我们说page1.jsp），它有一个html表单，action =page2.jsp。
在page1.jsp和page2.jsp中我有<％@ page contentType =text / html; charset = UTF-8pageEncoding =UTF-8％> < code>< meta http-equiv =Content-Typecontent =text / html; charset = UTF-8> 如果我在url（get方法）中看到的形式写出希腊字母，就像
HTTP：//本地主机：8080 // addProblem.jsp lastNameForm =％CF％84％CF％85％CE％B8％CF％84％CF％85％CE％B8％CF％84％CF％85安培; firstNameForm = & eMa ....

以及来自page2.Jsp并使用<％out.println （用request.getParameter（ lastNameForm））; ％>

我得到这个αÏÎααÏÎ'
我该怎么办？

解决方案

因此，您想要解码 GET 请求参数使用 UTF-8 字符编码。对于URL解码GET请求参数，您需要在服务器配置中设置字符编码。如何做到这一点取决于有问题的服务器，最好是使用关键字uri encoding。例如，在Tomcat中，您需要为中的< Connector> 元素的 URIEncoding code> server.xml ，另请参阅

 < Connector（...）URIEncoding =UTF-8/> gt ; 
  



HttpServletRequest＃setCharacterEncoding（） as Bozho上述仅适用于 POST 请求，其中参数包含在请求正文中而不是URL中。

更多背景信息以及您可能找到的所有解决方案的详细概述这篇文章有用。

I have a jsp page(let's say page1.jsp) which have an html form with action="page2.jsp". In page1.jsp and page2.jsp i have <%@page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%> outside the head section and <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> in the head section.

If i write greek letters in the form i see in the url(get method) something like that http://localhost:8080//addProblem.jsp?lastNameForm=%CF%84%CF%85%CE%B8%CF%84%CF%85%CE%B8%CF%84%CF%85&firstNameForm=&eMa ....

and from page2.Jsp with the use of <% out.println(request.getParameter("lastNameForm")); %>

i get this αÏδαÏδ What can i do?

解决方案

Thus, you want to URL-decode GET request parameters using UTF-8 character encoding. For URL-decoding GET request parameters you need to set the character encoding in the server configuration. How to do it depends on the server in question, best is to refer its documentation using the keywords "uri encoding". In for example Tomcat you need to set the URIEncoding attribute of the <Connector> element for HTTP requests in the server.xml, also see this document:

<Connector (...) URIEncoding="UTF-8" />

The HttpServletRequest#setCharacterEncoding() as Bozho mentioned only works for POST requests where the parameters are included in the request body instead of in the URL.
