Question

无法将图片上传到服务器......

以下是代码：

let chosenImage = info[UIImagePickerControllerEditedImage] as! UIImage
let data = UIImageJPEGRepresentation(chosenImage, 1)

Alamofire.upload(multipartFormData: { multipartFormData in
    multipartFormData.append(data, withName: "avatar_image")
    },
    to: url,
    method: .put,
    encodingCompletion: { encodingResult in
    switch encodingResult {
    case .success(let upload, _, _):
      upload.responseJSON { response in
        debugPrint(response)
      }
    case .failure(let encodingError):
      print(encodingError)
    }
})

如果将data更改为let data = Bundle.main.url(forResource: "flag", withExtension: "png")!，则会将此图片上传到服务器。

为什么它无法从我的照片库上传图片？

Answer 1

您可以尝试原创而不是编辑

let chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage

不知道为什么，但我必须上传文件网址。所以我把文件写到磁盘然后上传......

    let fileManager = FileManager.default
    let documentsPath = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first
    let imagePath = documentsPath?.appendingPathComponent("image.jpg")
    let chosenImage = info[UIImagePickerControllerEditedImage] as! UIImage
    let data = UIImageJPEGRepresentation(chosenImage, 0.5)
    try! UIImageJPEGRepresentation(chosenImage, 0.5)?.write(to: imagePath!)
    profileImageURL = imagePath

    Alamofire.upload(multipartFormData: { multipartFormData in
        multipartFormData.append(profileImageURL, withName: "avatar_image")},
        to: "https://api.booze.kz/v1/customers/\(phoneNumber)",
        method: .put,
        encodingCompletion: { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                 upload.responseJSON { response in
                     debugPrint(response)
                 }
            case .failure(let encodingError):
                 print(encodingError)
            }
    })
