Add Custom Header__jquery in Jquery

We know that you can add a custom request header when you send an AJAX request

Beforesend:function (Request) {
        Request.setrequestheader ("Test", "Chenxizhang");
}

However, you need to add a header to each AJAX request. So you can change the jquery library to do this.

We found the following code:

Setrequestheader:function (name, value) {
                    var lname = Name.tolowercase ();
                    if (!state) {
                        name = requestheadersnames[LName] = requestheadersnames[LName] | | name;
                        requestheaders[name] = value;
                        requestheaders["yourname"] = "Yourvalue";
                    }
                    return this;
                }

We can see that the send request header is sent in this place, so you can manually add the parameter of the request header and the value to meet the requirement in this position. Or you can override the Ajax method to extend the use.
