OpenAPI 自动生成接口请求代码

OpenAPI Typescript Codegen
Node.js库，该库基于OpenAPI规范生成Typescript客户端。
https://github.com/ferdikoomen/openapi-typescript-codegen
安装：

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

例如通过请求工具类 Axios：

openapi --input (这里是你的后端接口文档地址) --output ./generated --client axios

详细用法建议去查看readme

如果想要自定义请求参数，怎么办？
1）使用代码生成器提供的全局参数修改对象：
在/generated/core/OpenAPI.ts 可以修改请求地址

export const OpenAPI: OpenAPIConfig = {
    BASE: 'http://localhost:8101',
    VERSION: '1.0',
    WITH_CREDENTIALS: false,
    CREDENTIALS: 'include',
    TOKEN: undefined,
    USERNAME: undefined,
    PASSWORD: undefined,
    HEADERS: undefined,
    ENCODE_PATH: undefined,
};

2）直接定义 axios 请求库的全局参数，比如全局请求响应拦截器
文档：https://axios-http.com/docs/interceptors
示例代码：

// Add a request interceptor
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);
  }
);

我放在了/src/plugins/axios中
接着在main.ts中引入一下：

import "@/plugins/axios";
