How do I get response URL? about swifthttp

[acmacalister]

I added the URL to the HTTPResponse. So for example:

var request = HTTPTask()
//we have to add the explicit type, else the wrong type is inferred. See the vluxe.io article for more info.
let params: Dictionary<String,AnyObject> = ["param": "param1", "array": ["first array element","second","third"], "num": 23, "dict": ["someKey": "someVal"]]
request.POST("http://domain.com/create", parameters: params, success: {(response: HTTPResponse) in
        println(response.URL) // URL of response.
    },failure: {(error: NSError, response: HTTPResponse?) in

    })

Just pull the latest code and you should be golden.

Thanks for your response. What happens when there is a HTTP redirect?

Since it is just a wrapper around NSURLSessionDataTask according to Apple's Docs:

"If the delegate does not implement this method, the redirect is followed up to the maximum number of redirects."

We don't implement the delegate method, so it should just follow them by default. Check out the Apple docs for more info.

Excuse me if I'm asking too many question! Does NSURLSessionDataTask maintain cookies too? I'm asking because I want to do an "OAuth in memory". The login page has some cookies that is needed for POST operation when user clicks on login button. So I want to GET the login page, and then in the same session, POST to endpoint that login page form POST to with cookies.

Here is the flow I want to follow:

1. GET login page at /
2. After login loaded, POST to /login with cookies and username/password I got from user from previous GET request
3. After successful login, wait for redirects to resolve and then capture OAuth token from the URL.

Not at all. Questions are good 😄. SwiftHTTP is a pretty thin wrapper around NSURLSession, so I was just wanting to point you to source for docs from Apple. Cookies are in the same boat as redirects. We don't handle them directly and use just use the builtinNSHTTPCookieStorage for NSURLSession. According to the docs:

For default and background sessions, the default value is the shared cookie storage object.

For ephemeral sessions, the default value is a private cookie storage object that stores data in memory only, and is destroyed when you invalidate the session.

So by default cookies are per NSURLSession, or in more general terms stored per request. Not sure if this would help any, but I have a simple example Github app that implements Github's OAuth using SwiftHTTP. It doesn't use the "web flow", but might be helpful all the same.

Thank you very much! I'll try this.
