使用：
- HTTP Methods

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

---------------------------

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

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

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

• GET Request With URL-Encoded Parameters

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

• POST Request With URL-Encoded Parameters

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

Alamofire.request(.POST, "https://httpbin.org/post", parameters: parameters)
// HTTP body: foo=bar&baz[]=a&baz[]=1&qux[x]=1&qux[y]=2&qux[z]=3

• POST Request with JSON-encoded Parameters

let parameters = [
    "foo": [1,2,3],
    "bar": [
        "baz": "qux"
    ]
]

Alamofire.request(.POST, "https://httpbin.org/post", parameters: parameters, encoding: .JSON)
// HTTP body: {"foo": [1, 2, 3], "bar": {"baz": "qux"}}

• HTTP Headers

let headers = [
    "Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==",
    "Accept": "application/json"
]

Alamofire.request(.GET, "https://httpbin.org/get", headers: headers)
         .responseJSON { response in
             debugPrint(response)
         }

上传upload：

• Supported Upload Types

    File
    Data
    Stream
    MultipartFormData

• Uploading a File

let fileURL = NSBundle.mainBundle().URLForResource("Default", withExtension: "png")
Alamofire.upload(.POST, "https://httpbin.org/post", file: fileURL)

• Uploading with Progress

Alamofire.upload(.POST, "https://httpbin.org/post", file: fileURL)
         .progress { bytesWritten, totalBytesWritten, totalBytesExpectedToWrite in
             print(totalBytesWritten)

             // This closure is NOT called on the main queue for performance
             // reasons. To update your ui, dispatch to the main queue.
             dispatch_async(dispatch_get_main_queue()) {
                 print("Total bytes written on main queue: \(totalBytesWritten)")
             }
         }
         .validate()
         .responseJSON { response in
             debugPrint(response)
         }

• Uploading MultipartFormData

Alamofire.upload(
    .POST,
    "https://httpbin.org/post",
    multipartFormData: { multipartFormData in
        multipartFormData.appendBodyPart(fileURL: unicornImageURL, name: "unicorn")
        multipartFormData.appendBodyPart(fileURL: rainbowImageURL, name: "rainbow")
    },
    encodingCompletion: { encodingResult in
        switch encodingResult {
        case .Success(let upload, _, _):
            upload.responseJSON { response in
                debugPrint(response)
            }
        case .Failure(let encodingError):
            print(encodingError)
        }
    }
)

下载Downloading

Supported Download Types

Request
Resume Data

• Downloading a File

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

    return directoryURL.URLByAppendingPathComponent(pathComponent!)
}

使用默认的下载的目录：Using the Default Download Destination

let destination = Alamofire.Request.suggestedDownloadDestination(directory: .DocumentDirectory, domain: .UserDomainMask)
Alamofire.download(.GET, "https://httpbin.org/stream/100", destination: destination)

• Downloading a File w/Progress

Alamofire.download(.GET, "https://httpbin.org/stream/100", destination: destination)
         .progress { bytesRead, totalBytesRead, totalBytesExpectedToRead in
             print(totalBytesRead)

             // This closure is NOT called on the main queue for performance
             // reasons. To update your ui, dispatch to the main queue.
             dispatch_async(dispatch_get_main_queue()) {
                 print("Total bytes read on main queue: \(totalBytesRead)")
             }
         }
         .response { _, _, _, error in
             if let error = error {
                 print("Failed with error: \(error)")
             } else {
                 print("Downloaded file successfully")
             }
         }

• Accessing Resume Data for Failed Downloads访问下载失败的恢复数据

Alamofire.download(.GET, "https://httpbin.org/stream/100", destination: destination)
         .response { _, _, data, _ in
             if let
                 data = data,
                 resumeDataString = NSString(data: data, encoding: NSUTF8StringEncoding)
             {
                 print("Resume Data: \(resumeDataString)")
             } else {
                 print("Resume Data was empty")
             }
         }

The data parameter is automatically populated with the resumeData if available.数据参数自动填充resumeData如果可用。

let download = Alamofire.download(.GET, "https://httpbin.org/stream/100", destination: destination)
download.response { _, _, _, _ in
    if let
        resumeData = download.resumeData,
        resumeDataString = NSString(data: resumeData, encoding: NSUTF8StringEncoding)
    {
        print("Resume Data: \(resumeDataString)")
    } else {
        print("Resume Data was empty")
    }
}
