1. 在项目目录创建文件 swagger-js-codegen.js

const path = require("path");

var fs = require("fs");
var CodeGen = require("swagger-js-codegen").CodeGen;

var file = "swagger/swagger.json";
var swagger = JSON.parse(fs.readFileSync(file, "UTF-8"));
var reactjsSourceCode = CodeGen.getReactCode({
  className: "ClientApi",
  swagger: swagger,
  beautify: true
});

fs.writeFileSync(path.join(__dirname, "./src/api/swagger-js-codegen.js"), reactjsSourceCode);

2. 在package.json文件里创建脚本

  "scripts": {
    "start": "dotenv -e .env react-scripts start",
    "build": "react-scripts build",
    "build:uat": "dotenv -e .env.production react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "eslint-fix": "eslint --fix --ext .js --ext .jsx src/",
    "swagger-js-codegen": "node  swagger-js-codegen.js",
  },

3. 在命令行执行 npm swagger-js-codegen
