类型错误：axios.get 不是函数？

Question

不知道为什么我收到以下错误：

TypeError: axios.get is not a function

    4 |
    5 | export const getTotalPayout = async (userId: string) => {
  > 6 |   const response = await axios.get(`${endpoint}get-total-payout`, { params: userId });
    7 |   return response.data;
    8 | };
    9 |

我的服务：

import * as axios from 'axios';

const endpoint = '/api/pool/';

export const getTotalPayout = async (userId: string) => {
  const response = await axios.get(`${endpoint}get-total-payout`, { params: userId });
  return response.data;
};

我的笑话测试：

// import mockAxios from 'axios';
import { getTotalPayout } from './LiquidityPool';

const userId = 'foo';

describe('Pool API', () => {
  it('getTotalPayout is called and returns the total_payout for the user', async () => {
    // mockAxios.get.mockImplementationOnce(() => {
    //   Promise.resolve({
    //     data: {
    //       total_payout: 100.21,
    //     },
    //   });
    // });

    const response = await getTotalPayout(userId);
    console.log('response', response);
  });
});

在 src/__mocks__/axios.js 我有这个：

// tslint:disable-next-line:no-empty
const mockNoop = () => new Promise(() => {});

export default {
  get: jest.fn(() => Promise.resolve({ data: { total_payout: 100.21 }})),
  default: mockNoop,
  post: mockNoop,
  put: mockNoop,
  delete: mockNoop,
  patch: mockNoop
};

Answer 1

使用 import asimport Axios from "axios";代替import { Axios } from "axios";

Answer 2

请看：MDN

正如那里提到的，您需要一个值来收集default export和 其余的X。在这种情况下，您可以：

import axios, * as others from 'axios';

X在others这里。

代替

import * as axios from 'axios';

假设：... from 'axios'指的是你的玩笑模拟。如果这能回答您的问题，请告诉我。
