使用基本身份验证进行身份验证时遇到问题。我正在使用符合URLRequestConvertible协议的标准枚举来构造我的请求。问题是,当我在枚举中手动设置授权标头时,如下所示:
URLRequestConvertible
let user = *** let password = *** let credentialData = "\(user):\(password)".dataUsingEncoding(NSUTF8StringEncoding)! let base64Credentials = credentialData.base64EncodedStringWithOptions([]) mutableURLRequest.setValue("Basic \(base64Credentials)", forHTTPHeaderField: "Authorization")
我总是收到401未经授权的回复。 但是, 如果我authenticate像这样使用回调设置密码:
authenticate
Alamofire.request(request) .authenticate(user: "USERNAME_HERE", password: "PASSWORD_HERE") .responseJSON { (response) -> Void in print("JSON response \(response)") completion(success: true, error: nil) }
它正确认证。我希望能够在符合的枚举中手动进行设置,URLRequestConvertible而不是在中传递凭据authenticate。
我知道它正在使用NSURLCredential身份验证挑战的后台,但我希望能够手动设置它。
NSURLCredential
这是我的URLRequestConvertible实现:
enum CheckedUpAPI: URLRequestConvertible { static let baseURLString = "https://***" static let APIKey = "***" static let APIClientName = "iPad" case UpdatePatient(String, [String: AnyObject]) var method: Alamofire.Method { switch self { case .UpdatePatient: return .PATCH } } var path: String { switch self { case .UpdatePatient(let patientID, _): return "patients/\(patientID)" } } // MARK: URLRequestConvertible var URLRequest: NSMutableURLRequest { let URL = NSURL(string: CheckedUpAPI.baseURLString)! let mutableURLRequest = NSMutableURLRequest(URL: URL.URLByAppendingPathComponent(path)) mutableURLRequest.HTTPMethod = method.rawValue /** We are not setting any authorization headers since they requests return 401 the `authenticate` function on Alamofire.request does the trick let user = "easy@test.com" let password = "test" let credentialData = "\(user):\(password)".dataUsingEncoding(NSUTF8StringEncoding)! let base64Credentials = credentialData.base64EncodedStringWithOptions([]) mutableURLRequest.setValue("Basic \(base64Credentials)", forHTTPHeaderField: "Authorization") */ mutableURLRequest.setValue(CheckedUpAPI.APIKey, forHTTPHeaderField: "API-Key") switch self { case .UpdatePatient(_, let parameters): return Alamofire.ParameterEncoding.JSON.encode(mutableURLRequest, parameters: parameters).0 } } }
最终弄清楚了问题所在。它最终成为URL中缺少的尾随正斜杠。看来Alamofire不能像AFNetworking那样处理它。我能够弄清楚记录请求并看到我们在实际请求中丢失了一些字节。
