基于原swagger-parser 原因: 官方解析时如果存在不存在的schema的话会报错,避免这条不存在的报错
修改文件 dist/swagger-parser.js 10188行 已上传npm

yarn || npm 
npm i swagger-parser-reftychen

**引入注意,在直接引入的时候开发环境没有问题但应用到生产环境build打包后可能会存在打入的是node环境的执行代码导致bug请自行调试,当前版本只修改了dist浏览器端的代码 lib文件内的并未修改

import * as Swagger from 'swagger-parser-reftychen/dist/swagger-parser'

原则上应该下载官方架子修改里面依赖的 json-schema-ref-parser 的 dereference 方法 （pointer.js 86行的代码）然后通过官方的build:browser 方法构建出 dist 的内容,同时也可以修改json-schema-ref-parser等方法，但是本人比较懒就直接修改了 swagger-parser的dist文件。

以下是官方原文 2019-06-05及以前的 Swagger 2.0 and OpenAPI 3.0 parser/validator

Features

• Parses Swagger specs in JSON or YAML format
• Validates against the Swagger 2.0 schema or OpenAPI 3.0 Schema
• Resolves all $ref pointers, including external files and URLs
• Can bundle all your Swagger files into a single file that only has internal $ref pointers
• Can dereference all $ref pointers, giving you a normal JavaScript object that's easy to work with
• Tested in Node.js and all modern web browsers on Mac, Windows, and Linux
• Tested on over 1,000 real-world APIs from Google, Instagram, Spotify, etc.
• Supports circular references, nested references, back-references, and cross-references
• Maintains object reference equality — $ref pointers to the same value always resolve to the same object instance

Example

SwaggerParser.validate(myAPI, function(err, api) {
  if (err) {
    console.error(err);
  }
  else {
    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
  }
});

Or use Promises syntax instead. The following example is the same as above:

SwaggerParser.validate(myAPI)
  .then(function(api) {
    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
  })
  .catch(function(err) {
    console.error(err);
  });
