Koa-swagger：设置cors后访问控制来源错误

Question

我正在玩弄 koa 和 swagger。即使在我设置了 cors 之后，它也会给我 "may not have the appropriate access-control-origin settings" 的错误。

App.js

var cors = require('koa-cors');

var swaggerApp = koa(),
    port = 8080;

var options = {
    origin: '*',
    headers: ['Content-Type', 'Authorization','Origin', 'X-Requested-With']
}


curl i http://localhost:8080/api-docs.json

HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET,HEAD,PUT,POST,DELETE
Access-Control-Allow-Headers: Content-Type,Authorization,Origin,X-Requested-With
Content-Type: application/json; charset=utf-8
Content-Length: 203

{"basePath":"http://localhost:8080","apiVersion":"1.0","swaggerVersion":"1.0","swaggerURL":"/swagger","swaggerJSON":"/api-docs.json","apis":[{"path":"/api-docs.json/root","description":"All about API"}]}

不幸的是，当出现 CORS 错误时，swagger ui 无法给出完整的警告。对于您的情况，请查看 http://localhost:8080/api-docs.json/root 是否存在。否则，您可能会收到相同的错误消息。

看起来 swagger 定义是 quite old (1.0)。你能看看使用更新的库吗，比如 https://github.com/swagger-api/swagger-node?
