我刚刚开始看看Mattt的美妙的新Alamofire swift网络库，不知道如何使用它与自定义标题。
代码我试图从AFNetworking转换为Alamofire是这样的：
let request = NSMutableURLRequest(URL: url) request.setValue(authorizationToken,forHTTPHeaderField:"Authorization")
根据官方文档，不建议修改会话配置：
This is not recommended for Authorization or Content-Type headers.
Instead,use URLRequestConvertible and ParameterEncoding,
respectively.
因此，用于授权的URLRequestConvertible的示例用法是：
enum Router: URLRequestConvertible {
static let baseUrlString = "some url string"
case Get(query: String)
var URLRequest: NSMutableURLRequest {
let (path: String,parameters: [String: AnyObject]?) = {
switch self {
case .Get(let query):
return ("/get",["q": query])
}
}()
let URL = NSURL(string: Router.baseUrlString)!
let URLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path))
// set header fields
URLRequest.setValue("a",forHTTPHeaderField: "Authorization")
let encoding = Alamofire.ParameterEncoding.URL
return encoding.encode(URLRequest,parameters: parameters).0
}
}
以及当您想要提出请求时：
Manager.sharedInstance.request(Router.Get(query: "test"))

老答案
截至Alamofire v1.0 Pers回答不再有效。在新版本中，附加标题应该添加到NSURLSessionConfiguration的HTTPAdditionalHeaders属性
Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders = ["Authorization": authorizationToken]
