解決Json傳輸中文亂碼問題

1、如果是通過URL傳遞：----需要編碼兩次

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) {
}
})
},

后台通過：

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

反編譯一下就可以獲取到傳遞的中文~~

2、  直接通過ajax數據傳遞：只需編譯一次~

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) {
}
})
},

后台直接獲取到傳遞的值，需要解碼一次：

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