Auto parameter string default value without double quotation make api docs generating failed

[Taizeng Wu]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind bug

What happened:

nirvana api starting failed with logging:

FATAL 0321-12:50:40.034+08 api.go:61 | json: error calling MarshalJSON for type spec.Swagger: json: error calling MarshalJSON for type *spec.Paths: json: error calling MarshalJSON for type spec.PathItem: json: error calling MarshalJSON for type *spec.Operation: json: error calling MarshalJSON for type spec.OperationProps: json: error calling MarshalJSON for type spec.Parameter: json: error calling MarshalJSON for type *swagger.rawJSON: invalid character 'w' looking for beginning of value

What you expected to happen:

nirvana api can work correctly.

How to reproduce it (as minimally and precisely as possible):

Define a struct which relating to Auto parameter, set string default value without double quotation:

type Option struct {
  Hello string `source:"Query,hello,default=world"`
}

Anything else we need to know?:

If set default value with double quotation, then nirvana api can work, but bussiness function will be getting addition double quotation from that option.

type Option struct {
  Hello string `source:"Query,hello,default=\"world\""`
}

Additionally, how to support not basic type correctly, e.g.

type Option struct {
  Hello string `source:"Query,hello,default=\"world\""`
  Timeout time.Duration `source:"Query,timeout,default=10s"`
  Perm os.FileMode `source:"Query,perm,default=0755"`
}

For non-basic types, you can register custom converters by service.RegisterConverter().

But it does not work with api docs generating by resgister converter. Wei Guo <[e-mail]>于2019年3月21日 周四下午7:09写道：

The marjor issue is normal parameter default value coming from json decoding which will including double quotation for string type or base string type, but for auto parameter default value coming from tag default raw value. Taizeng Wu <[e-mail]>于2019年3月21日 周四下午7:13写道：

It's a problem. I have not found an effective way to make them work together.
