feat(api): add extra form content type and extract endpoints from path

[leoujz]

api gateway:

• handing http request adds Content-Type application/x-www-form-urlencoded support
• extract endpoints from path if no endpoint matched, only in api case

Nice!

Could you explain a bit how the endpoint extraction works?

If I'm not mistaken it now limits you to only have one slash in your URL for your method

[leoujz]

The original code use rsp.Method as the endpoint name. As the strategy mentioned in https://github.com/go-micro/api, I extract the endpoint name from rsp.Path. If any endpoint matched before this code, this would never happen, this only runs when no endpoint mathced, as a final default value. when using rsp.Method, like POST, GET, would never work.

And 3 failing checks relative to my code? I don't know how to fix that

Makes sense, thanks for the PR!

Checks are not relative to your change.
