Alamofile使用

Swift, iOS

Alamofire 是Swift版的 AFNetworking，是非常方便实用的第三方网络操作框架；

使用方法：

Alamofire.request(method: Method, URLString: URLStringConvertible, parameters: [String : AnyObject]?, encoding: ParameterEncoding, headers: [String : String]?).response (options: NSJSONReadingOptions, completionHandler: { (NSURLRequest, NSHTTPURLResponse?, NSData?, NSError?) -> Void in
    //操作数据
})

但是上面方法中有些参数可以省略，基本用法如下：

Alamofire.request(.GET, "URL").responseJSON(options: NSJSONReadingOptions.AllowFragments) { (_, _, json, _) -> Void in
    //操作数据
    
}

获取数据的方法

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

HTTP Methods

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"
}

请求需要的参数parameters

类型是一个字典 [String : AnyObject]

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

下载文件

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

这些都只是Alamofire的常规使用，更加详细的使用方法其官方网站上有详细描述。
