Detailed explanation of Vue's ajax public method instance

This article mainly shares an ajax public method based on Vue (detailed explanation). It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look, I hope it can help everyone.

In order to reduce the redundancy of the code, we decided to extract the public method of requesting ajax for colleagues to use.

I used ES6 syntax to write this method.

/**
  * @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);
    }
   });
  });
 }

Return the request result through the callback function.

The test code is as follows:

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);
    })
   }

The test passed!
