發出請求

import Alamofire
Alamofire.request(.GET, url)

響應處理

Alamofire.request(.GET, url, parameters: ["key": "value"])
         .responseJSON { response in
             print(response
 
.request)  
             print(response.response) 
             print(response.data)   
             print(response.result) 
             if let JSON = response.result.value {
                 print("JSON: \(JSON)")
             }
         }

響應JSON處理

Alamofire.request(.GET, url)
         .responseJSON { response
 
 in
             debugPrint(response)
         }

HTTP方法

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

上傳檔案

let fileURL = NSBundle.mainBundle().URLForResource("Default", withExtension: "png")
Alamofire.upload(.POST, url, file: fileURL)

上傳進度

Alamofire.upload(.POST, url, 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)")
             }
         }
         .responseJSON { response in
             debugPrint(response)
         }

下載

Alamofire.download(.GET, url) { temporaryURL, response in
    let fileManager = NSFileManager.defaultManager()
    let directoryURL = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
    let pathComponent = response.suggestedFilename

    return directoryURL.URLByAppendingPathComponent(pathComponent!)
}

HTTP頭部

Alamofire.request(.GET, url, headers: ["key":"value"])
         .responseJSON { response in
             debugPrint(response)
         }
