How do I add a value to an http header?

[ericjim]

I am interested in adding an additional value to the following GET request's header:

let galleryRequest = Alamofire.request(.GET, "https://api.imgur.com/3/gallery.json")
    .responseString { (request, response, string, error) in
         // Do something...
    }

The header in question is: Authorization: Client-ID YOUR_CLIENT_ID where the client_id would be my imgur client_id.

Thanks for the awesome library!

For anything beyond what the shorthand provides, you'll have to drop down a level of abstraction to create and manage NSURLRequest objects yourself. This may change in a future version, but for now, here's the process:

let URL: NSURL(string: "http://api.imgur.com/3/gallery.json")
var mutableURLRequest = NSMutableURLRequest(URL: URL)
mutableURLRequest.setValue("...", forHTTPHeaderField: "Authorization")

let manager = Alamofire.Manager.sharedInstance // or create a new one
let request = manager.request(mutableURLRequest)
request.responseString { (request, response, string, error) in
         // ...
}

Alternatively, you could also set the Authorization on the defaultHeaders of a manager. This would automatically apply the header to all requests created through method shorthand.

Real documentation for this usage is forthcoming.

Same comment as in #7 applies here as well. Would be great if new features weren't just closed but marked as new features. Thank you.

@mattt Hi! Is your example valid for POST requests as well? I tried it but it returns 405 - method not allowed error.

I tried explicitly specifying the http method in the url request like this,

mutableRequest.HTTPMethod = "POST"

Then I got a 500 - internal server error.

EDIT: Yes, I'm sending it as a GET request. That's the cause of the 405 error. I tested it using hurl.it. Please show how to add a http header of a POST request as well? Also how do I add normal parameters to this POST request?

Attempt: Okay, I got it working. The reason I got the 500 error was because I had forgotten to append the parameter. I accomplished it by adding these few extra lines.

mutableRequest.HTTPMethod = "POST"
let postString = "UniqueId=\(uniqueID)"
mutableRequest.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)

Now it works fine. I hope you're working on something to simplify this process. :)

I would like to re-open this issue. Sending additional request headers is mandatory on any REST API.

For custom headers and POST parameters I used something like this (Swift). Hope it helps.

/// Creates a POST to the API, returning an Alamofire request that
/// you can work with. Does NOT MAKE THE CALL
/// :param: params a dictionary of parameters to add to the body
func post(url: String, params: Dictionary<String, AnyObject>) -> Request {
  let URL = NSURL(string: url)!
  let req = NSMutableURLRequest(URL: URL)
  req.HTTPMethod = "POST"
  req.setValue("some-value", forHTTPHeaderField: "MyCustomHeader")
  req.HTTPBody = params.toURLString().dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)
  return Alamofire.request(req).validate(statusCode: 200 ..< 300)
}
