The background parameter for passing parameters in vue.js ajax is not application/x-www-form-urlencoded MIME.

< H2 > post request filter encodeURI not resolved! Using contentType will not help. < / H2 >

Test environment 1:ajax with parameter request: name
google
get/post unchanged
foreground: pass name directly (the value can be obtained)
background: the decoding / puzzle effect is consistent
when the parameter name value is requested to the background through the browser ajax request, it is not
application/x-www-form-urlencoded MIME value

< H2 > the effect is consistent with the coding < / H2 >

the request request value for the browser is application/x-www-form-urlencoded MIME
request 200

personal consideration: inconsistent coding between foreground and background

Front end:

data() {
    var name=this.$route.query.name;
        $.ajax({
            url : "topInfo?name="+name,
            contentType: "application/json; charset=utf-8",
            type : "POST", //GET
            async : false, //false,
            //timeout : 5000, //
            dataType : "json", //:
            success : function(data) {
                this.items = data.data;
            },
            error : function(data) {
                alert("!!");
            }
