使用Alamofire进行基本身份验证

问题描述

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建我的请求。问题是，当我在枚举中手动设置授权标头时，如下所示：

  let user = *** 
 let password = *** 
 
 let credentialData =\（user）：\（password）。dataUsingEncoding（NSUTF8StringEncoding）！ 
 let base64Credentials = credentialData.base64EncodedStringWithOptions（[]）
 
 mutableURLRequest.setValue（Basic \（base64Credentials），forHTTPHeaderField：Authorization）
  

我总是得到401未经授权的回复。 然而如果我使用 authenticate 回调设置密码，如下所示：

  Alamofire.request（request）
 .authenticate（user：USERNAME_HERE，password：PASSWORD_HERE）
 .responseJSON {（response） - >无效
打印（JSON响应\（响应））
完成（成功：true，错误：无）
} 
  

它正确验证。我希望能够在符合 URLRequestConvertible 的enum中手动设置它，而不是传入 authenticate 中的凭据。

我知道它在auth挑战下使用 NSURLCredential 但我希望能够设置这是我的 URLRequestConvertible 实现：

 枚举CheckedUpAPI：URLRequestConvertible {
 static let baseURLString =https：// ***
 static let APIKey =***
 static let APIClientName =iPad
 
 
 case UpdatePatient（String，[String：AnyObject]）
 
 
 var method：Alamofire.Method {
切换自我{
 case .UpdatePatient：
 return .PATCH 
} 
} 
 
 var path：String {
 switch self {
 case .UpdatePatient（let patientID，_）：
返回patients / \（pat） ientID）
} 
} 
 
 // MARK：URLRequestConvertible 
 
 var URLRequest：NSMutableURLRequest {
 let URL = NSURL（string： CheckedUpAPI.baseURLString）！ 
 let mutableURLRequest = NSMutableURLRequest（URL：URL.URLByAppendingPathComponent（path））
 mutableURLRequest.HTTPMethod = method.rawValue 
 
 
 / ** 
我们是没有设置任何授权标题，因为他们请求返回401 
 Alamofire.request上的`authenticate`函数可以解决问题
 
 let user =[e-mail]
 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，参数：参数）.0 
} 
} 
} 
  

解决方案

最终找出问题所在。它最终成为URL中缺少的尾随斜杠。似乎Alamofire没有像AFNetworking那样处理它。我能够弄清楚记录请求并发现我们在实际请求中丢失了一些字节。

Experiencing an issue when authenticating with Basic Auth. I am using a standard enum that conforms to URLRequestConvertible protocol to construct my requests. The issue is that when I manually set the authorization headers in the enum like so:

    let user = ***
    let password = ***

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

    mutableURLRequest.setValue("Basic \(base64Credentials)", forHTTPHeaderField: "Authorization")

I always get a 401 unauthorized response. However if I set the password using the authenticate callback like so:

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

It authenticates properly. I would like to be able to set it manually in the enum conforming to URLRequestConvertible instead of passing in the credentials in authenticate.

I know it's using a NSURLCredential under the hood for auth challenges but I would like to be able to set it manually.

Here is my URLRequestConvertible implementation :

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 = "[e-mail]"
        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
        }
    }
}

解决方案

Ultimately figured out what the issue was. It ended up being a missing trailing forward slash in the URL. It seems Alamofire does not handle it the same way AFNetworking does. I was able to figure it out logging the requests and seeing that we were losing some bytes in the actual request.
