Use custom HTTP Headers with AFNetworking 3.0

I want to use my http header If-None-Match but I don't find how with AFNetworking 3.0

The Migration Guide doesn't explain anything about that and basically just say to use a normal GET request which doesn't seems helping for me.

Here's what I was doing with AFNetworking 2:

let getAvatarRequest = NSURLRequest(URL: avatarUrl!, cachePolicy: .ReloadIgnoringLocalCacheData, timeoutInterval: 60).mutableCopy()    
getAvatarRequest.setValue(avatarImageETag!, forHTTPHeaderField: "If-None-Match")

Thanks for your help.

Solution

  • Ok I found the answer, nothing actually changed, but it's not obvious, here's the code:

    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
let manager = AFURLSessionManager(sessionConfiguration: configuration)

let request = NSMutableURLRequest(URL: remoteFileURL!)
request.setValue("", forHTTPHeaderField: "If-None-Match")
let downloadTask = manager.downloadTaskWithRequest(request, progress: nil, destination: { (targetURL: NSURL, response: NSURLResponse) -> NSURL in
    // Success
}, completionHandler: { (response: NSURLResponse, filePath: NSURL?, error: NSError?) -> Void in
    // Error
})
downloadTask.resume()
