Missing mandatory field: 'host'

[Techbrunch]

I ran into this issue a couple of time:

The OpenAPI specification contained in https://.../api/v2/swagger/json is missing the mandatory field: 'host'

Adding the host in the JSON fixed the issue:

{
    "basePath": "/api/v2",
    "host": "www.xxx.com",
    "definitions": {

I would be nice to default the host to the host of the swagger doc when it's not set and we pass a URL to OpenAPI Parser.

I totally agree with this solution, I solved the same problem adding the host in the JSON.
