本文主要和大家分享AJAX之POST数据中文乱码如何解决，前端使用encodeURI进行编码，希望能帮助到大家。var param = encodeURI(param);

$.ajax({

url: 'url',

methodtype: "POST",

async: false,

timeout: 60000,

contentType: "application/json",

data: {'param':param},

success: function(data) {

},

error: function(data) {

}

});

后台java.net.URLDecoder进行解码
