我使用此代码进行用户登录表单问题是我可以从Internet Explorer登录但是当我从Firefox登录时,相同的代码会在屏幕上打印HTML代码版本。

此代码在登录后打印待处理列表:

 <%@ page language = "java" import="java.util.Iterator"  import="java.util.ArrayList"     import="java.lang.*" contentType = "text/html; charset = ISO-8859-1"
     %>
<%@ page errorPage="/error.jsp" %>
<%    
    response.setHeader("Pragma", "no-cache");
    response.setHeader("Cache-Control", "no-store");
    response.setHeader("Expires", "0");
    response.setDateHeader("Expires", -1);
    //session = request.getSession(false);
    //               session.invalidate();
    //             session = request.getSession(true);
 %>

当内容被解释为text/plain而不是text/html时,就会发生这种情况。这只能表示HTTP响应Content-Type已设置为text/plain,或已损坏或丢失。

使用HTTP流量检查器检查HTTP响应标头。如果您安装了Firebug,请按F12并选中 Net 标签。 Content-Type标题必须至少说text/html。默认情况下已经是这种情况。也许你有一些Filter做错了。


对于具体问题,

无关,与在问题中最初发布的JSP代码中指定响应字符编码不一致。您在HTTP响应标头中指定了ISO-8859-1,并且您在HTML元头中指定了UTF-8。这毫无意义。但是,这不应该引起这种问题。

顺便说一下,&#34;信息技术部&#34;然后那个写旧的学校风格的JSP充满了被弃用的HTML元素和糟糕的做法......?这是一个业余爱好网站还是什么?
