React Ts 项目配置 Axios

React Hooks Ts Axios

React项目Ts版，使用Hooks API。本示例主要是配置Axios并使用Eggjs写了两个接口进行测试。

主要看 ./src/api 和 ./src/model 目录。

├─ src
│  ├─ api
│  │  ├─ api.ts
│  │  └─ status.ts
│  ├─ model
│  │  └─ login.ts

import axios, {AxiosInstance, AxiosRequestConfig, AxiosResponse} from 'axios';
import qs from 'qs'

import { showMessage } from "./status";
import { message, Spin } from 'antd';
import { ILogin, IUser } from 'model/login';


// 返回res.data的interface
export interface IResponse {
  code: number | string;
  data: any;
  msg: string;
}

let axiosInstance:AxiosInstance = axios.create({
  baseURL: process.env.REACT_APP_BASE_URL,
  headers: {
    Accept: "application/json",
    "Content-Type": "application/x-www-form-urlencoded"
  },
  transformRequest: [
    function(data) {
      //由于使用的 form-data传数据所以要格式化
      delete data.Authorization;
      data = qs.stringify(data);
      return data;
    }
  ]
});

// axios实例拦截响应
axiosInstance.interceptors.response.use(
  (response: AxiosResponse) => {
    if (response.headers.authorization) {
      localStorage.setItem('app_token', response.headers.authorization);
    } else {
      if (response.data && response.data.token) {
        localStorage.setItem('app_token', response.data.token);
      }
    }

    if (response.status === 200) {
      return response;
    } else {
      showMessage(response.status);
      return response;
    }
  },
  // 请求失败
  (error: any) => {
    const {response} = error;
    if (response) {
      // 请求已发出，但是不在2xx的范围
      showMessage(response.status);
      return Promise.reject(response.data);
    } else {
      message.error('网络连接异常,请稍后再试!');
    }
  }
);

// axios实例拦截请求
axiosInstance.interceptors.request.use(
  (config: AxiosRequestConfig) => {
    const token = localStorage.getItem('app_token');
    if (token) {
      config.headers.Authorization = `Bearer ${token}`
    }
    return config;
  },
  (error:any) => {
    return Promise.reject(error);
  }
)
