Ajax設置自定義請求頭的兩種方法

用自定義請求頭token為例

方法一

$.ajax({
            type: "post",
            url:"http://127.0.0.1:4564/bsky-app/template/testPost",
            contentType: "application/json;charset=utf-8",//這個參數也是header參數
            data :JSON.stringify({"bodyName":"sdfsdf","date":"2017-11-28 07:34:01","price": 10.5,"tbId": 1}),
            dataType: "json",
            //這里是重點
            beforeSend: function (XMLHttpRequest) {
               XMLHttpRequest.setRequestHeader("token", "eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIxOD.....");
            },
            success: function (data) {
                alert(data);
            },error:function(error){
                console.log(error);
            }
        });

方法二

$.ajax({
         type: type,
         headers: {
             'Access-Token':$.cookie('access_token')
         },
         url: url,
         data: data,
         success: function(data) {
         },
         error: function(err) {
         },
         complete: function(XMLHttpRequest, status) { //請求完成后最終執行參數　
         }
});
