一、setting参数 headers

$.ajax({

    headers: {         Accept: "application/json; charset=utf-8"     },     type: "get",     success: function (data) {     } });

二、beforeSend方法

$("#test").click(function() { $.ajax({ type: "GET", url: "default.aspx", beforeSend: function(request) { request.setRequestHeader("Test", "Chenxizhang"); }, success: function(result) { alert(result); } }); });

#微服务之间用@RequestHeader传递
