Alamofire是 Swift 语言的 HTTP 网络开发工具包,相当于Swift实现AFNetworking版本。
当然,AFNetworking非常稳定,在Mac OSX与iOS中也能像其他Objective-C代码一样用Swift编写。不过Alamofire更适合Swift语言风格习惯(Alamofire与AFNetworking可以共存一个项目中,互不影响).
Alamofire 取名来源于 Alamo Fire flower
使用CocoaPods安装，在podfile
1 source ‘https://github.com/CocoaPods/Specs.git‘ 2 platform :ios, ‘8.0‘ 3 use_frameworks! 4 5 pod ‘Alamofire‘, ‘~> 1.2‘
submodule 方式安装 1 $ git submodule add https://github.com/Alamofire/Alamofire.git
1.下载源码将Alamofire.xcodeproj拖拽至工程中如下图: 
2.工程->Build Phases->Target Dependencies 增加Alamofire 
3.点击如下图“+”按钮选择"New Copy Files Phase"添加,改名为“Copy Frameworks”并 选择选项下的“ Destination”为“ Frameworks”，然后添加“Alamofire.framework”
4.在需要使用的swift文件中加入import Alamofire，如下图: 
1.0版本将在Swift 1.0发布之后。
Xcode 6
iOS 7.0+ / Mac OS X 10.9+
1 Alamofire.request(.GET, "http://httpbin.org/get") 带参数
1 Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
Response结果处理
1 Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"]) 2 .response { (request, response, data, error) in 3 println(request) 4 println(response) 5 println(error) 6 }
Response结果字符串处理
1 Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"]) 2 .responseString { (request, response, string, error) in 3 println(string) 4 }
Alamofire.Method enum 列表出在RFC 2616中定义的HTTP方法 §9:
1 public enum Method: String { 2 case OPTIONS = "OPTIONS" 3 case GET = "GET" 4 case HEAD = "HEAD" 5 case POST = "POST" 6 case PUT = "PUT" 7 case PATCH = "PATCH" 8 case DELETE = "DELETE" 9 case TRACE = "TRACE" 10 case CONNECT = "CONNECT" 11 }
这些值可以作为Alamofire.request请求的第一个参数.
1 Alamofire.request(.POST, "http://httpbin.org/post") 2 3 Alamofire.request(.PUT, "http://httpbin.org/put") 4 5 Alamofire.request(.DELETE, "http://httpbin.org/delete")
1 let parameters = [ 2 "foo": "bar", 3 "baz": ["a", 1], 4 "qux": [ 5 "x": 1, 6 "y": 2, 7 "z": 3 8 ] 9 ]
1 Alamofire.request(.POST, "http://httpbin.org/post", parameters: parameters) 发送以下HttpBody内容:
1 foo=bar&baz[]=a&baz[]=1&qux[x]=1&qux[y]=2&qux[z]=3 Alamofire 使用Alamofire.ParameterEncoding可以支持URL query/URI form,JSON, PropertyList方式编码参数。
Parameter Encoding
1 enum ParameterEncoding { 2 case URL 3 case JSON(options: NSJSONWritingOptions) 4 case PropertyList(format: NSPropertyListFormat, 5 options: NSPropertyListWriteOptions) 6 7 func encode(request: NSURLRequest, 8 parameters: [String: AnyObject]?) -> 9 (NSURLRequest, NSError?) 10 { ... } 11 }
NSURLRequest方式编码参数
1 let URL = NSURL(string: "http://httpbin.org/get") 2 var request = NSURLRequest(URL: URL) 3 4 let parameters = ["foo": "bar"] 5 let encoding = Alamofire.ParameterEncoding.URL 6 (request, _) = encoding.encode(request, parameters)
POST JSON格式数据
1 Alamofire.request(.POST, "http://httpbin.org/post", parameters: parameters, encoding: .JSON(options: nil)) 2 .responseJSON {(request, response, JSON, error) in 3 println(JSON) 4 }
支持的类型
上传文件
1 let fileURL = NSBundle.mainBundle() 2 .URLForResource("Default", 3 withExtension: "png") 4 5 Alamofire.upload(.POST, "http://httpbin.org/post", file: fileURL)
1 Alamofire.upload(.POST, "http://httpbin.org/post", file: fileURL) 2 .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in 3 println(totalBytesWritten) 4 } 5 .responseJSON { (request, response, JSON, error) in 6 println(JSON) 7 }
支持的类型
下载文件
1 Alamofire.download(.GET, "http://httpbin.org/stream/100", destination: { (temporaryURL, response) in 2 if let directoryURL = NSFileManager.defaultManager() 3 .URLsForDirectory(.DocumentDirectory, 4 inDomains: .UserDomainMask)[0] 5 as? NSURL { 6 let pathComponent = response.suggestedFilename 7 8 return directoryURL.URLByAppendingPathComponent(pathComponent) 9 } 10 11 return temporaryURL 12 })
下载到默认路径
1 let destination = Alamofire.Request.suggestedDownloadDestination(directory: .DocumentDirectory, domain: .UserDomainMask) 2 3 Alamofire.download(.GET, "http://httpbin.org/stream/100", destination: destination)
下载进度
1 Alamofire.download(.GET, "http://httpbin.org/stream/100", destination: destination) 2 .progress { (bytesRead, totalBytesRead, totalBytesExpectedToRead) in 3 println(totalBytesRead) 4 } 5 .response { (request, response, _, error) in 6 println(response) 7 }
支持以下几种认证
Http basic认证
1 let user = "user" 2 let password = "password" 3 4 Alamofire.request(.GET, "https://httpbin.org/basic-auth/\(user)/\(password)") 5 .authenticate(HTTPBasic: user, password: password) 6 .response {(request, response, _, error) in 7 println(response) 8 }
采用NSURLCredential&NSURLProtectionSpace方式认证
1 let user = "user" 2 let password = "password" 3 4 let credential = NSURLCredential(user: user, password: password, persistence: .ForSession) 5 let protectionSpace = NSURLProtectionSpace(host: "httpbin.org", port: 0, `protocol`: "https", realm: nil, authenticationMethod: NSURLAuthenticationMethodHTTPBasic) 6 7 8 9 Alamofire.request(.GET, "https://httpbin.org/basic-auth/\(user)/\(password)") 10 .authenticate(usingCredential: credential, forProtectionSpace: protectionSpace) 11 .response {(request, response, _, error) in 12 println(response) 13 }
1 let request = Alamofire.request(.GET, "http://httpbin.org/ip") 2 3 println(request) 4 // GET http://httpbin.org/ip (200)
1 let request = Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"]) 2 3 debugPrintln(request)
1 $ curl -i 2 -H "User-Agent: Alamofire" 3 -H "Accept-Encoding: Accept-Encoding: gzip;q=1.0,compress;q=0.5" 4 -H "Accept-Language: en;q=1.0,fr;q=0.9,de;q=0.8,zh-Hans;q=0.7,zh-Hant;q=0.6,ja;q=0.5" 5 "http://httpbin.org/get?foo=bar"
