直接新建openApi.js，然后替换下你的url，然后node openApi.js即可生成serverce文件夹

const OpenApiTool = require('baikaifa-openapi-tool');
const { resolve } = require('path');

const url = 'https://gw.alipayobjects.com/os/antfincdn/M%24jrzTTYJN/oneapi.json';
const outputDir = resolve(__dirname, 'service');

const openApiTool = new OpenApiTool({ url });
openApiTool.generateService({
    template: 'axios',
    importText: `import axios from '@/common/apiService';`,
    typescript: true,
    pinYin:false,//如果生成的文件名是中文则转换为拼音
    outputDir,
    format: (openapi) => {
    return openapi;
  },
});
