ajax设置header

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);
}
});
});
