Ajax设置自定义请求头的两种方法

示例用自定义请求头token为例

• 方法一

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

主要用到这句

        beforeSend: function (XMLHttpRequest) {
            XMLHttpRequest.setRequestHeader("token", "eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIxOD.....");
        },

• 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) { //请求完成后最终执行参数　
         }
});

主要用到这句

         headers: {
             'token':'token_value'
         },
