Alamofire（Swift 3）：对成员“上传（..”）的模糊引用

【问题描述】：

我将Alamorefire 用于Swift 3，但出现错误：Ambiguous reference to member 'upload。 这是我的代码：

Alamofire.upload(
    .post,
    url,
    multipartFormData:  multipartFormData in
        // import parameters
        for i in 0 ..< params.count 
            for (key, value) in params[i] 
                multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!,
                                                 name: key)
            
        
        // import image to request
        multipartFormData.appendBodyPart(data: imageData,
                                         name: "file",
                                         fileName: "file.jpg",
                                         mimeType: "image/jpeg")
    ,
    encodingMemoryThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold,
    encodingCompletion:  encodingResult in
        switch encodingResult 
        case .Success(let upload, _, _):
            upload.responseJSON  response in
                debugPrint(response.result)
            
        case .Failure(let encodingError):
            print(encodingError)
        
    
)

我的代码有什么问题？

【问题讨论】：

请回复我的回答。

我遇到了同样的问题。我的问题是我试图为“headers”参数传递[String : String] 字典。我通过写HTTPHeaders(myDictionary) 将字典显式转换为HTTPHeaders 解决了这个问题。

【参考方案1】：

试试下面的代码

Alamofire.upload(multipartFormData:  (multipartFormData) in
    multipartFormData.append(UIImageJPEGRepresentation(self.photoImageView.image!, 0.5)!, withName: "photo_path", fileName: "swift_file.jpeg", mimeType: "image/jpeg")
    for (key, value) in parameters 
        multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
    
    , to:"http://server1/upload_img.php")
 (result) in
    switch result 
    case .success(let upload, _, _):

        upload.uploadProgress(closure:  (Progress) in
            print("Upload Progress: \(Progress.fractionCompleted)")
        )

        upload.responseJSON  response in
            //self.delegate?.showSuccessAlert()
            print(response.request)  // original URL request
            print(response.response) // URL response
            print(response.data)     // server data
            print(response.result)   // result of response serialization
            //                        self.showSuccesAlert()
            //self.removeImage("frame", fileExtension: "txt")
            if let JSON = response.result.value 
                print("JSON: \(JSON)")
            
        

    case .failure(let encodingError):
        //self.delegate?.showFailAlert()
        print(encodingError)

这个答案提供了一段与问题中完全不同的代码，它没有解释原始代码的实际错误。
