如何使用Swift将ImageView中的映像上传到邮政API

Question

我正在实现用户配置文件模块。为此，我想存储用户配置文件，该用户配置文件是从相机或画廊中选择的。我想将其传递到API中，但我不知道该怎么做。

以下是我的代码。

var request = URLRequest(url: URL(string: "http://xxxx.xx/UpdateEmp_test?xx=(xx)&PermanentAddress=(ADDrEss)&PermVillage=(townCITY)&PermTaluk=(taulkcode!)&PermDist=(districtcode!)&PermPinCode=(PINcode)&PermState=(statecode!)&FatherName=(FatherNaME)&MotherName=(MothERName)&profile_image=(imagePath)")!)
        print(request)
        request.httpMethod = "POST"
        let session = URLSession(configuration: .default)
        session.dataTask(with: request) {data, response, error in
            guard error == nil && data != nil else
            {
                let alert = UIAlertController(title: "Check your Internet Connection", message: "", preferredStyle: .alert)
                self.present(alert, animated: true, completion: nil)
                let when = DispatchTime.now() + 3
                DispatchQueue.main.asyncAfter(deadline: when)
                {
                    // your code with delay
                    alert.dismiss(animated: true, completion: nil)
                }
                return
            }

            do
            {
                let json = try JSONSerialization.jsonObject(with: data!, options: [])
                print(json)
                let message  = (json as AnyObject).value(forKey: "message") as! NSString
                print(message)
                DispatchQueue.main.sync {
                    if message == "success" {
                        let alert = CustomAlert(title:"Request Updated Successfully!")
                        alert.show(animated: true)
                        self.dismiss(animated: true, completion:nil)
                    }
                    else if message == "Already"{
                        let alert = CustomAlert(title:"Already Request Updated")
                        alert.show(animated: true)
                    }
                    else {
                        let alert = CustomAlert(title:"Failed,Try Again!")
                        alert.show(animated: true)
                    }
                }
            }
            catch
            {
            }
            }.resume()

您可以将图像转换为base64字符串并将其发送到服务器：

let imageData:NSData = UIImagePNGRepresentation(yourUIImage.image)!

编码：

let strBase64 = imageData.base64EncodedString(options: .lineLength64Characters)

解码：

let dataDecoded:NSData = NSData(base64EncodedString: strBase64, options: NSDataBase64DecodingOptions(rawValue: 0))!
let decodedimage:UIImage = UIImage(data: dataDecoded)!
yourImageView.image = decodedimage
