解决Json传输中文乱码问题

1、如果是通过URL传递：----需要编码两次

var searchText = this.searchText();
searchText = encodeURI(searchText);
searchText = encodeURI(searchText);
$.ajax({
type: 'GET',
url: $ctx + this.pageUrl + pageIndex + "&searchText=" + searchText,
data: '',
contentType: 'text/json,charset=utf-8',
dataType: 'json',
success: function(data) {
}
})
},

后台通过：

String queryCon = request.getParameter("searchText");
if(queryCon != null && queryCon != ""){
queryCon=URLDecoder.decode(queryCon,"utf-8");
}

反编译一下就可以获取到传递的中文~~

2、  直接通过ajax数据传递：只需编译一次~

var searchText = this.searchText();
searchText = encodeURI(searchText);
$.ajax({
type: 'GET',
url: $ctx + this.pageUrl + pageIndex ,
data: {search：searchText },
contentType: 'text/json,charset=utf-8',
dataType: 'json',
success: function(data) {
}
})
},

后台直接获取到传递的值，需要解码一次：

String queryCon = search;
if(queryCon != null && queryCon != ""){
queryCon=URLDecoder.decode(queryCon,"utf-8");
}
