Easy cookies management about siesta

[pcantrell]

Cookie-based auth in an API (as opposed to a web site) is unusual and somewhat unorthodox, so I wouldn’t want to build special handling for it directly into Siesta itself.

If you do need cookie handling, that’s a responsibility that’s best left to the underlying networking library plus your app-specific rules for allowing & storing cookies. You’d add your own beforeStartingRequest hook to add cookie headers before sending the request, then receive cookie headers on receiving the response. That could even make a nice little lib.

For examples of the code you’d need to put in the beforeStartingRequest hook, see:

Thank you, I'll follow your advices; I haven't other options, since I don't own the server side

Yes, we often have to make things work well with the APIs we’re given.

I’ll close this for now, but please do ask if you hit a snag with your Siesta configuration. The basic structure will be something like this:

service.configure {
  addStoredCookiesTo($0.config.headers)

  $0.config.beforeStartingRequest {
    _, req in
    req.onSuccess {
      entity in
      storeCookiesFrom(entity.headers)
    }
  }
}

func addStoredCookiesTo(inout headers: [String:String]) {
  // for each stored cookie
    header[cookieKey] = formattedCookieValue
}

func storeCookiesFrom(headers: [String:String]) {
  // parse any cookie headers
  if newCookieDetected {
    // store cookie
    service.invalidateConfiguration() // crucial!
  }
}

Ok, thanks a lot!

@nabbestemmia did you solve this? I have the same requirement to receive and send back a cookie but can't get it to work.
