Swift 如何使用带有自定义标题的 Alamofire

根据官方文件，不建议修改会话配置:

对于授权或内容类型标题，不建议这样做.

因此，URLRequestConvertible用于授权的一个示例是:

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
    }
}

当你想提出请求时:

Manager.sharedInstance.request(Router.Get(query: "test"))

老生常谈

从阿拉莫菲尔v1开始.0答案不再有效.在新版本中，应在NSURLSessionConfiguration的HTTPAdditionalHeaders属性中添加其他标题

Alamofire.Manager.sharedInstance.session.configuration.HTTPAdditionalHeaders = ["Authorization": authorizationToken]
