问题描述
这是我的服务器JSP代码Server_Date.jsp
This is my server JSP code "Server_Date.jsp"
<%
response.setHeader("cache-control", "no-cache");
response.setContentType("text/event-stream");
out.print("data: " + (new java.util.Date()).toString() + "x\n\n");
out.flush();
%>
我的客户端jsp页面Client_Serverdate.jsp
This my client jsp page "Client_Serverdate.jsp"
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body onload="begin()">
<h1>Getting server updates</h1>
<div id="result"></div>
<script >
if(typeof(EventSource)!=="undefined")
{
var source=new EventSource("Server_Date.jsp");
source.addEventListener("message", function(event) {
document.getElementById("result").innerHTML = event.data;
}, false);
}
else
{
document.getElementById("result").innerHTML="Sorry, your browser does not support server-sent events...";
}
</script>
</body>
</html>
请帮我这个代码在Mozilla Firefox中工作正常，歌剧但不在Google Chrome中工作我是用18.x和20.x检查
Please help me this code is working fine in Mozilla Firefox, opera but not working in Google chrome i was checked with 18.x and 20.x also
它将进入我用print语句检查的服务器页面，但它没有到达document.getElementById行结果）。innerHTML = event.data;
It is going to server page i have checked with print statement but its not coming to the line "document.getElementById("result").innerHTML = event.data;"
谢谢......
推荐答案
问题解决了
解决方案：
页面编码问题：客户端使用UTF-8编码
Page encoding problem : client side used UTF-8 Encoding
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
未提及服务器端UTF-8，因此在setContentType中添加charset = UTF-8后
Server side UTF-8 was not mention, so after adding charset=UTF-8 in setContentType its working
response.setContentType("text/event-stream;charset=UTF-8");
