ios - 使用 Alamofire 进行基本身份验证

Question

使用 Basic Auth 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，当我像这样在枚举中手动设置授权标头时：

    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 未经授权的响应。但是authenticate，如果我像这样使用回调设置密码：

    Alamofire.request(request)
        .authenticate(user: "USERNAME_HERE", password: "PASSWORD_HERE")
        .responseJSON { (response) -> Void in
            print("JSON response \(response)")
            completion(success: true, error: nil)
    }

它正确地进行了身份验证。我希望能够在符合的枚举中手动设置它，URLRequestConvertible而不是在authenticate.

我知道它正在使用NSURLCredential引擎盖下的身份验证挑战，但我希望能够手动设置它。

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
        }
    }
}

在 Swift 3.0 中

使用以下代码 -

    let user = ***
    let password = ***
    let credentialData = "\(user):\(password)".data(using: String.Encoding.utf8)!
    let base64Credentials = credentialData.base64EncodedString(options: [])
    let headers = ["Authorization": "Basic \(base64Credentials)"]

    Alamofire.request(customerURL,
                      method: .get,
                      parameters: nil,
                      encoding: URLEncoding.default,
                      headers:headers)
        .validate()
        .responseJSON { response in
            if response.result.value != nil{                    
               print(response)
            }else{

            }
    }

Alamofire.request(urlString, method: .get).authenticate(user: "username", password: "pwd").responseJSON

你可以试试这段代码：

    let user = ***
    let password = ***
    let credentialData = "\(user):\(password)".dataUsingEncoding(NSUTF8StringEncoding)!
    let base64Credentials = credentialData.base64EncodedStringWithOptions([])
    let headers = ["Authorization": "Basic \(base64Credentials)"]

Alamofire.manager.request(.GET, stringURL,headers: headers, parameters: params as? [String : AnyObject])
        .responseJSON { response  in
            if (response.result.error == nil){
                success(data: response.result.value)
            }else{
                fail(error: response.result.error)
            }
    }

斯威夫特 4

private func getHeaders() -> [String: String] {
        let userName = "xxxx"
        let password = "xxxx"
        let credentialData = "\(userName):\(password)".data(using: .utf8)
        guard let cred = credentialData else { return ["" : ""] }
        let base64Credentials = cred.base64EncodedData(options: [])
        guard let base64Date = Data(base64Encoded: base64Credentials) else { return ["" : ""] }
        return ["Authorization": "Basic \(base64Date.base64EncodedString())"]
    }

Alamofire 提供了一种比手动创建自己的标题更简单的方法。

此处“基本身份验证”部分的相关代码：

  manager.request(.GET, "https://api.parse.com/1/classes/Spot/")
    .authenticate(user: username, password: password)
    .responseSpotsArray { response in
      completionHandler(response.result)
    }

终于知道是什么问题了。它最终成为 URL 中缺少的尾部正斜杠。似乎 Alamofire 并没有像 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。
