尝试通过Alamofire 4.0上传图像时，“ParameterEncoding”类型没有成员“URL”

Question

我在将Alamofire更新到版本4.0之前使用相同的代码将图像上传到服务器并且它工作得非常好但是现在我有这些错误我正在尝试很多，但每次出现新错误时：< / p>

第一个错误：

第二个错误：

我的代码：

func uploadFile()  {

      let image = UIImage(named: "ios9.jpg")
      let newimage : NSData = UIImageJPEGRepresentation(selectedImage.image!, 32)! as NSData

     let newRandomName = randomStringWithLength(32)
     let fname = (newRandomName as String) + ".jpg"

     let parameters = [
     "pic"           :NetData(data: newimage as Data, mimeType: .ImageJpeg, filename: fname),
     "msg"     :self.detailmsg,
     "customer_key" : self.CUSTOMER_KEY
     ] as [String : Any]



     let urlRequest = self.urlRequestWithComponents("link", parameters: parameters as NSDictionary)


     //First error here
     Alamofire.upload(urlRequest.0, data: urlRequest.1)
     .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
     print("\(totalBytesWritten) / \(totalBytesExpectedToWrite)")
     }
     .responseJSON { response in
     debugPrint(response)
     }

}


func urlRequestWithComponents(_ urlString:String, parameters:NSDictionary) -> (URLRequestConvertible, NSData) {

    // create url request to send
    let mutableURLRequest = NSMutableURLRequest(url: URL(string: urlString)!)
    mutableURLRequest.httpMethod = Alamofire.HTTPMethod.post.rawValue
    //let boundaryConstant = "myRandomBoundary12345"
    let boundaryConstant = "NET-POST-boundary-\(arc4random())-\(arc4random())"
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")


    // create upload data to send
    let uploadData = NSMutableData()

    // add parameters
    for (key, value) in parameters {

        uploadData.append("\r\n--\(boundaryConstant)\r\n".data(using: String.Encoding.utf8)!)

        if value is NetData {
            // add image
            let postData = value as! NetData


            //uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"; filename=\"\(postData.filename)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

            // append content disposition
            let filenameClause = " filename=\"\(postData.filename)\""
            let contentDispositionString = "Content-Disposition: form-data; name=\"\(key)\";\(filenameClause)\r\n"
            let contentDispositionData = contentDispositionString.data(using: String.Encoding.utf8)
            uploadData.append(contentDispositionData!)


            // append content type
            //uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) // mark this.
            let contentTypeString = "Content-Type: \(postData.mimeType.getString())\r\n\r\n"
            let contentTypeData = contentTypeString.data(using: String.Encoding.utf8)
            uploadData.append(contentTypeData!)
            uploadData.append(postData.data as Data)

        }else{
            uploadData.append("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".data(using: String.Encoding.utf8)!)
        }
    }
    uploadData.append("\r\n--\(boundaryConstant)--\r\n".data(using: String.Encoding.utf8)!)



    // return URLRequestConvertible and NSData
   // return (Alamofire.ParameterEncoding.encode(mutableURLRequest as! ParameterEncoding).0, uploadData)

    //Second error here
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}

let image = UIImage(named: "ios9.jpg")
let params:[String:Any] = ["msg": self.detailmsg,
                           "customer_key": self.CUSTOMER_KEY]

let urlRequest = try! URLRequest(url: url, method: .post, headers: nil)

Alamofire.upload(multipartFormData: { (multipartFormData) in

    if let imageData = UIImageJPEGRepresentation(image!, 1.0){
         multipartFormData.append(imageData, withName: "pic", fileName:"image.jpg", mimeType: "image/jpg")
    }
    for (key, value) in self.parameters! {
        let data = "\(value)".data(using: .utf8)
        multipartFormData.append(data!, withName: key)
    }

}, with: urlRequest) { (result) in
       switch result{
       case .success(let request, _, _):
           request.responseJSON { response in
              debugPrint(response)
           }
       case .failure(let error):
             print(error.localizedDescription)
        }
}
