Usage

GET Request

Alamofire.request(.GET, "http://httpbin.org/get")

With Parameters

Alamofire.request(.GET,
                  "http://httpbin.org/get",
                  parameters: ["foo": "bar"])

With Response Handling

Alamofire.request(.GET,
                  "http://httpbin.org/get",
                  parameters: ["foo": "bar"])
         .response { (request, response, data, error) in
                     println(request)
                     println(response)
                     println(error)
                   }

With Response String Handling

Alamofire.request(.GET,
                  "http://httpbin.org/get",
                  parameters: ["foo": "bar"])
         .responseString { (request, response, string, error) in
                  println(string)
         }

HTTP Methods

The Alamofire.Method enum lists the HTTP methods defined in RFC 2616 §9:

public enum Method: String {
    case OPTIONS = "OPTIONS"
    case GET = "GET"
    case HEAD = "HEAD"
    case POST = "POST"
    case PUT = "PUT"
    case PATCH = "PATCH"
    case DELETE = "DELETE"
    case TRACE = "TRACE"
    case CONNECT = "CONNECT"
}

These values can be passed as the first argument of the Alamofire.request method:

Alamofire.request(.POST, "http://httpbin.org/post")

Alamofire.request(.PUT, "http://httpbin.org/put")

Alamofire.request(.DELETE, "http://httpbin.org/delete")

POST Request

let parameters = [
    "foo": "bar",
    "baz": ["a", 1],
    "qux": [
        "x": 1,
        "y": 2,
        "z": 3
    ]
]

Alamofire.request(.POST,
                  "http://httpbin.org/post",
                  parameters: parameters)

This sends the following HTTP Body:

foo=bar&baz[]=a&baz[]=1&qux[x]=1&qux[y]=2&qux[z]=3

Alamofire has built-in support for encoding parameters as URL query / URI form encoded, JSON, and Property List, using the Alamofire.ParameterEncoding enum:

Parameter Encoding

enum ParameterEncoding {
    case URL
    case JSON(options: NSJSONWritingOptions)
    case PropertyList(format: NSPropertyListFormat,
                      options: NSPropertyListWriteOptions)

    func encode(request: NSURLRequest,
                parameters: [String: AnyObject]?) ->
                    (NSURLRequest, NSError?)
    { ... }
}

Manual Parameter Encoding of an NSURLRequest

let URL = NSURL(string: "http://httpbin.org/get")
var request = NSURLRequest(URL: URL)

let parameters = ["foo": "bar"]
let encoding = Alamofire.ParameterEncoding.URL
(request, _) = encoding.encode(request, parameters)

POST Request with JSON Response

Alamofire.request(.POST,
                  "http://httpbin.org/post",
                  parameters: parameters,
                  encoding: .JSON(options: nil))
         .responseJSON {(request, response, JSON, error) in
            println(JSON)
         }

Built-In Response Methods

• response()
• responseString(encoding: NSStringEncoding)
• responseJSON(options: NSJSONReadingOptions)
• responsePropertyList(options: NSPropertyListReadOptions)

Uploading

Supported Upload Types

• File
• Data
• Stream
• Multipart (Coming Soon)

Uploading a File

let fileURL = NSBundle.mainBundle()
                      .URLForResource("Default",
                                      withExtension: "png")

Alamofire.upload(.POST,
                 "http://httpbin.org/post",
                 file: fileURL)

Uploading w/Progress

Alamofire.upload(.POST,
                 "http://httpbin.org/post",
                 file: fileURL)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseJSON { (request, response, JSON, error) in
            println(JSON)
        }

Downloading

Supported Download Types

• Request
• Resume Data

Downloading a File

Alamofire.download(.GET,
                  "http://httpbin.org/stream/100",
                  destination: { (temporaryURL, response) in
    if let directoryURL = NSFileManager.defaultManager()
                          .URLsForDirectory(.DocumentDirectory,
                                            inDomains: .UserDomainMask)[0]
                          as? NSURL {
        let pathComponent = response.suggestedFilename

        return directoryURL.URLByAppendingPathComponent(pathComponent)
    }

    return temporaryURL
})

Using the Default Download Destination Closure Function

let destination =
    Alamofire.Request.suggestedDownloadDestination(directory: .DocumentDirectory,
                                                   domain: .UserDomainMask)

Alamofire.download(.GET,
                   "http://httpbin.org/stream/100",
                   destination: destination)

#### Downloading a File w/Progress

```swift
Alamofire.download(.GET,
                   "http://httpbin.org/stream/100",
                   destination: destination)
         .progress { (bytesRead, totalBytesRead, totalBytesExpectedToRead) in
             println(totalBytesRead)
         }
         .response { (request, response, _, error) in
             println(response)
         }

Authentication

Supported Authentication Schemes

• HTTP Basic
• HTTP Digest
• Kerberos
• NTLM

HTTP Basic Authentication

let user = "user"
let password = "password"

Alamofire.request(.GET, "https://httpbin.org/basic-auth/\(user)/\(password)")
    .authenticate(HTTPBasic: user, password: password)
    .response {(request, response, _, error) in
        println(response)
    }

Authenticating with NSURLCredential & NSURLProtectionSpace

let user = "user"
let password = "password"

let credential = NSURLCredential(user: user,
                                 password: password,
                                 persistence: .ForSession)
let protectionSpace = NSURLProtectionSpace(host: "httpbin.org",
                                           port: 0,
                                           `protocol`: "https",
                                           realm: nil, authenticationMethod: NSURLAuthenticationMethodHTTPBasic)

Alamofire.request(.GET, "https://httpbin.org/basic-auth/\(user)/\(password)")
    .authenticate(usingCredential: credential, forProtectionSpace: protectionSpace)
    .response {(request, response, _, error) in
        println(response)
}

println(request)
// GET http://httpbin.org/ip (200)
