How to solve the Chinese garbled code of AJAX POST data

This article mainly shares with you how to solve the Chinese garbled code of AJAX POST data. The front-end uses encodeURI for encoding. I hope it can help everyone.

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) {

        }
    });
