jq设置http头部信息和获取头部信息

获取头部信息

$.ajax({
success: function(data, status, xhr) {
console.log(xhr.getResponseHeader("Content-Type"));
}
});

设置头部信息

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);
}
});
});
