我使用Alamofire按下按钮上传图像，但它显示错误
AF.upload(multipartFormData: {MultipartFormData方法行
（注意：Alamofire.upload在Alamofire 5.0更新后更改为AF.upload）
@IBAction func btnUploadImage(_ sender: UIButton) {
let uploadDict = ["user_id":getUserId] as [String:String]
AF.upload(multipartFormData: { MultipartFormData in
let image :Data = UIImageJPEGRepresentation(self.uploadImg.image!, 1.0)!
MultipartFormData.append(image, withName: "image" , fileName: "image.jpeg" , mimeType: "image/jpeg")
for(key,value) in uploadDict{
MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)}
}, to: "http://XXXXXXXXXXXXXXXX/uploadImage", encodingCompletion: {
EncodingResult in
switch EncodingResult{
case .success(let upload, _, _):
upload.responseJSON { response in
debugPrint("SUCCESS RESPONSE: \(response)")
}
case .failure(let encodingError):
print("ERROR RESPONSE: \(encodingError)")
} })

我刚安装了pods
pod 'Alamofire', '~> 5.0.0-beta.5'
//示例代码
let image: UIImage? = self.uploadImg.image;
let uploadDict = ["user_id":getUserId] as [String:String]
Alamofire.upload(multipartFormData: { MultipartFormData in
let image :Data = (image?.jpegData(compressionQuality: 1))!
MultipartFormData.append(image, withName: "image" , fileName: "image.jpeg" , mimeType: "image/jpeg")
