将图像从ImageVIew上传到远程服务器

Question

我正在尝试将图像从ImageView上传到远程服务器。

这是我的代码：

func subir_imagen(){

        let image = self.foto.image
        let imgData = image!.jpegData(compressionQuality: 1)!

         let parameters = ["name": "jogua"] //Optional for extra parameter

        Alamofire.upload(multipartFormData: { multipartFormData in
                multipartFormData.append(imgData, withName: "fileset",fileName: "file.jpg", mimeType: "image/jpg")
                for (key, value) in parameters {
                        multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
                    } //Optional for extra parameters
            },
        to:"https://.../subir_foto_dispositivo.php")
        { (result) in
            switch result {
            case .success(let upload, _, _):

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

                upload.responseJSON { response in
                    print(response)
                }

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

    }

这是文件subir_foto_dispositivo.php：

 // Save the image file
 move_uploaded_file($_FILES["image"]["tmp_name"], $_FILES["image"]["name"]);

 // Send some dummy result back to the iOS app
 $result = array();
 $result["user"] = $user;
 $result["message"] = "Success!";
 $result["files"] = $_FILES;
 $result["post"] = $_POST;
 echo json_encode($result);

这是上传图像时调试器中的输出：

Upload Progress: 0.21640112366409928
Upload Progress: 0.4362101390394442
Upload Progress: 0.6628349378372804
Upload Progress: 0.8485650361001688
Upload Progress: 1.0
SUCCESS: {
    files =     {
        fileset =         {
            error = 0;
            name = "file.jpg";
            size = 9615058;
            "tmp_name" = "/tmp/phpH6Au4W";
            type = "image/jpg";
        };
    };
    message = "Success!";
    post =     {
        name = jogua;
    };
    user = "<null>";
}

我没有收到任何警告或错误，但是图像没有上传到服务器，至少在文件夹中找不到它。

我想我缺少什么。

以下为我工作：

for item in imageParameter{
            if item as? UIImage != nil { //check here image is null or not
                let image = item as! UIImage
                if let imgjpgData = image.jpegData(compressionQuality: 0.3){
                    imageData.append(imgjpgData)
                }
            }
        }
        Alamofire.upload(multipartFormData: { (multipartFormData) in
            for (key, value) in params  {
                if let data = value.data(using: String.Encoding.utf8.rawValue) {
                    multipartFormData.append(data, withName: key)
                }
            }
            for data in imageData {
                multipartFormData.append(data, withName: "file", fileName: "image.jpg", mimeType: "image/jpeg")
            }
        }, usingThreshold: UInt64.init(), to: serverUrl, method: .post, headers: localHeaders) { (result) in
            switch result{
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    print("Succesfully uploaded")//other stuff}

这可能有帮助。

更新：

        var tempImg: UIImage?
        if let img = self.imgViewProfile.image{
            tempImg = img
        }
        else{
          //image is null
       }
