阿拉莫菲尔斯威夫特3号+；PHP上传图像不工作

我试图在我的服务器上使用Alamofire和PHP上传一个图像，我在这里检查了所有不同的问题，但由于某种原因它无法工作。我已经用HTML测试了我的PHP文件，它成功地上传了一个图像，所以它的范围缩小到我的swift代码

斯威夫特：

    let URL = "http://example.com/post_pic.php"
    let imageData = UIImageJPEGRepresentation(imageView.image!, 1)


    Alamofire.upload(multipartFormData: { (multipartFormData) in
        multipartFormData.append(imageData!, withName: "imageFile", mimeType: "image/jpeg")
    }, to:URL)
    { (result) in
        switch result {
        case .success(let upload, _, _):

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

            upload.responseJSON { response in
                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):
            print("Failure:")
            print(encodingError)
        }

    }

PHP:

我得到的答复是：

 Optional(<NSHTTPURLResponse: 0x17022df20> { URL: http://example.com/post_pic.php } { 
      status code: 200, headers {
     Connection = "Keep-Alive";
     "Content-Length" = 25;
     "Content-Type" = "application/json";
     Date = "Wed, 25 Jan 2017 10:16:29 GMT";
     "Keep-Alive" = "timeout=5, max=100";
     Server = "Apache/2.4.7 (Ubuntu)";
     "X-Powered-By" = "PHP/5.5.9-1ubuntu4.20";
 } })
      Optional(25 bytes)
      SUCCESS
      JSON: {
          response = "file_error";
      }

可选（{URL:http://example.com/post_pic.php } { 
状态代码：200，标题{
连接=“保持活动”；
“内容长度”=25；
“内容类型”=“应用程序/json”；
日期=“2017年1月25日星期三10:16:29 GMT”；
“保持活动”=“超时=5，最大=100”；
Server=“Apache/2.4.7（Ubuntu）”；
“X-Powered-By”=“PHP/5.5.9-1ubuntu4.20”；
} })
可选（25字节）
成功
JSON:{
response=“文件错误”；
}

我可以在我的应用程序中使用此代码

let URL = "http://example.com/post_pic.php"
let imageData = UIImageJPEGRepresentation(imageView.image!, 1)


    upload(multipartFormData: { multipartFormData in
                    multipartFormData.append(imageData!, withName: "imageFile", fileName: "file.jpg", mimeType: "image/jpeg")
        },
            to: URL, method: .post,
            encodingCompletion: { encodingResult in

                switch encodingResult {
                case .success(let upload, _, _):


                    upload.validate()
                    upload.responseJSON { response in


                        if response.result.error != nil {
                            print("failure")
                            UIAlertView(title: "Fail", message: "Please retry again.", delegate: nil, cancelButtonTitle: "Ok").show()
                        } else {
                            print("success")


                        }
                    }
                case .failure(let encodingError):
                    print(encodingError)

                }
        }
        )
