ios - 在 iOS 中使用 Alamofire 上传图片

Question

我正在尝试使用 Alamofire 上传图片，但它似乎无法上传。

    Alamofire.upload(multipartFormData: { multipartFormData in
        multipartFormData.append(imgData, withName: "data", fileName: "\(Date().timeIntervalSince1970).jpg", mimeType: "image/jpg")
        multipartFormData.append(operaID.data, withName: "id")
    },
                     to: URL_CORDINATE)
    { (result) in
        switch result {
        case .success(let upload, _, _):

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

            upload.responseJSON { response in
                print("Upload image response:", response.result.value)
            }

        case .failure(let encodingError):
            print("Error while uploading image:", encodingError)
        }

我期待看到图片上传，但是正文似乎有问题(我应该在正文中传递 img 和 id 而不是作为参数!)

但它在 Postman 中确实有效:/image/f0mUd.png

你可以试试这个:

Alamofire.upload(
                multipartFormData: { multipartFormData in
                    multipartFormData.append(imgData!, withName: "img", fileName: "jpg", mimeType: "image/jpeg")
            },
                to: UPLOAD_IMAGE_URL,
                encodingCompletion: { (encodingResult) -> Void in
                    switch encodingResult {
                    case .success(let upload, _, _):
                        upload.responseJSON { response in
                            let result = response.data
                            do {
                                print("success")
                            }catch {
                                print("error")
                            }
                        }
                    case .failure(let encodingError):
                        print(encodingError)

                    }
            })
