引入 axios，根据 api 文档生成调用接口

起步 | Axios Docs

安装 axios

npm install axios

生成 api 调用接口【可选】

https://github.com/ferdikoomen/openapi-typescript-codegen

1. 安装

   npm install openapi-typescript-codegen --save-dev

2. 然后执行生成代码

   http://localhost:8805/api/user/v3/api-docs：这个是接口文档url【返回的json】

   ./generated: 代表的是生成的路径

   axios: 指定的客户端 axios

   openapi --input http://localhost:8805/api/user/v3/api-docs --output ./generated --client axios

1. 测试

   import { Swagger3Service } from '../generated/services/Swagger3Service'

   setTimeout(() => {
   Swagger3Service.test()
   }, 1000)

如果想要自定义请求参数，怎么办？

使用代码生成器提供的全局参数修改对象

https://github.com/ferdikoomen/openapi-typescript-codegen/blob/master/docs/openapi-object.md

export const OpenAPI: OpenAPIConfig = {
  BASE: 'http://localhost:3000/api',
  VERSION: '2.0',
  WITH_CREDENTIALS: false,
  CREDENTIALS: 'include',
  TOKEN: undefined,
  USERNAME: undefined,
  PASSWORD: undefined,
  HEADERS: undefined,
  ENCODE_PATH: undefined,
};

直接定义 axios 请求库的全局参数，比如全局请求响应拦截器

Interceptors | Axios Docs

import axios from "axios";

axios.interceptors.request.use(
  function (config) {
    // Do something before request is sent
    return config;
  },
  function (error) {
    // Do something with request error
    return Promise.reject(error);
  }
);

// Add a response interceptor
axios.interceptors.response.use(
  function (response) {
    console.log("响应", response);
    // Any status code that lie within the range of 2xx cause this function to trigger
    // Do something with response data
    return response;
  },
  function (error) {
    // Any status codes that falls outside the range of 2xx cause this function to trigger
    // Do something with response error
    return Promise.reject(error);
  }
);
