基于Vue的ajax公共方法(详解)

/**  * @param type 请求类型，分为POST/GET  * @param url 请求url  * @param contentType  * @param headers  * @param data  * @returns {Promise<any>}  */ ajaxData: function (type, url, contentType, headers, data) {  return new Promise(function(resolve) {   $.ajax({    type: type,    url: url,    data: data,    timeout: 30000, //超时时间：10秒    headers: headers,    success: function(data) {     resolve(data);    },    error: function(XMLHttpRequest, textStatus, errorThrown) {     resolve(XMLHttpRequest);    }   });  }); }

getAjaxDataMethod: function () {    const url = "";    const type = "POST";    const contentType = "application/json";    const headers = {};    const data = {};    Api.ajaxData(type, url, contentType, headers, data).then(function (res) {     console.log(res);    }).catch(function (err) {     console.log(err);    })   }
