Spring, Tomcat, Web, Blog, .net js、URL传递含中文参数时的乱码问题解决
web前端-js教程
1、使用代码完成字符集修改
手机展示网站源码,ubuntu升级重启黑屏,爬虫中提取数据,php将ascii,seo系统导航lzw
方法(一):
html页面:
培训机构crm源码,vscode关键字斜体,ubuntu掉网,tomcat删除启动配置,stata爬虫分析,php微信图片生成,贵州seo网络推广是什么,免费下载源程序的网站,bootstrap 主题模板lzw
function testOne() {
画面比较好的网游源码,ubuntu强制删除分区,汽车类网站爬虫,php 炒股,seo 刷流量lzw
var url = “testOne_test.do?expr=”+你好;
location = encodeURI(url);
}
后台java代码:
String expr = new String(request.getParameter(“expr”).getBytes(“ISO-8859-1″),”UTF-8”);
方法(二):
html页面:
function testOne() {
var url = “testOne_test.do?expr=”+你好;
location = encodeURI(encodeURI(url));
}
后台java代码:
String expr = .URLDecoder.decode(lrequest.getParameter(“expr”) , “UTF-8”);
2、修改tomcat中的配置参数
在tomcat下面找到server.xml
根据需要修改为UTF-8等字符集。
3、在web工程中添加spring.jar,使用spring的CharacterEncodingFilter
view plaincopy to clipboardprint?
encoding
org.springframework.web.filter.CharacterEncodingFilter
encodingUTF-8
encoding
/*
org.springframework.web.filter.CharacterEncodingFilter 中的转码部分:
view plaincopy to clipboardprint?
protected void doFilterInternal(
HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
if (this.encoding != null && (this.forceEncoding || request.getCharacterEncoding() == null)) {
request.setCharacterEncoding(this.encoding);
if (this.forceEncoding && responseSetCharacterEncodingAvailable) {
response.setCharacterEncoding(this.encoding);
}
}
filterChain.doFilter(request, response);
}
