# Axios > 原文：[https://docs.gitlab.com/ee/development/fe_guide/axios.html](https://docs.gitlab.com/ee/development/fe_guide/axios.html) * [CSRF token](#csrf-token) * [Usage](#usage) * [Mock Axios response in tests](#mock-axios-response-in-tests) * [Example](#example) * [Mock poll requests in tests with Axios](#mock-poll-requests-in-tests-with-axios) # Axios[](#axios "Permalink") 我们使用[Axios](https://github.com/axios/axios)在 Vue 应用程序和大多数新代码中与服务器进行通信. 为了确保设置了所有默认值，您不应*直接使用 Axios* ，而应从`axios_utils`导入 Axios. ## CSRF token[](#csrf-token "Permalink") 我们所有的请求都需要 CSRF 令牌. 为了确保设置此令牌，我们将导入[Axios](https://github.com/axios/axios) ，设置令牌并导出`axios` . 应该使用此导出模块，而不是直接使用 Axios 以确保已设置令牌. ## Usage[](#usage "Permalink") ``` import axios from './lib/utils/axios_utils'; axios.get(url) .then((response) => { // `data` is the response that was provided by the server const data = response.data; // `headers` the headers that the server responded with // All header names are lower cased const paginationData = response.headers; }) .catch(() => { //handle the error }); ``` ## Mock Axios response in tests[](#mock-axios-response-in-tests "Permalink") 为了帮助我们模拟响应，我们使用[axios-mock-adapter](https://github.com/ctimmerm/axios-mock-adapter) . 比[`spyOn()`](https://jasmine.github.io/api/edge/global.html#spyOn)优势： * 无需创建响应对象 * 不允许通话（我们要避免） * 简单的 API 来测试错误情况 * 提供`replyOnce()`以允许不同的响应 我们还决定不使用[Axios 拦截器，](https://github.com/axios/axios#interceptors)因为它们不适合模拟. ### Example[](#example "Permalink") ``` import axios from '~/lib/utils/axios_utils'; import MockAdapter from 'axios-mock-adapter'; let mock; beforeEach(() => { // This sets the mock adapter on the default instance mock = new MockAdapter(axios); // Mock any GET request to /users // arguments for reply are (status, data, headers) mock.onGet('/users').reply(200, { users: [ { id: 1, name: 'John Smith' } ] }); }); afterEach(() => { mock.restore(); }); ``` ### Mock poll requests in tests with Axios[](#mock-poll-requests-in-tests-with-axios "Permalink") 因为轮询功能需要一个标头对象，所以我们需要始终包含一个对象作为第三个参数： ``` mock.onGet('/users').reply(200, { foo: 'bar' }, {}); ```
