如何在 Koush ion 中構建 URL

Question

我正在構建一個應用程序以將圖像上傳到我的公司服務器我正在使用 koush-ion 進行上傳，現在我的問題是我必須根據通過編輯文本框在另一個活動（登錄活動）中輸入的信息動態更改上傳的 URL，我不明白該怎么做，所以我想要發生的是客戶端輸入他們的電子郵件、密碼和 clientID（4 位數字）（在 LoginActivity 中），應用程序使用它來構建一個像這樣上傳的 url（在 CameraActivity 中） ) https://www.blahpractice.co.za/files-upload-ruben.asp?MyForm=Yes&ClientID=1234&Username=man@blahpractice.co.za&Pwd=BlahBlah123@

我從 koush github 得到了這個，我不確定這是否是我正在尋找的，以及如何從 koush-ion 中的另一個活動實現數據

發布應用程序/x-www-form-urlencoded 並讀取一個字符串

 Ion.with(getContext())
   .load("https://koush.clockworkmod.com/test/echo")
   .setBodyParameter("goop", "noop")
   .setBodyParameter("foo", "bar")
   .asString()
   .setCallback(...)

我想在這里調用網址

  File imageFile = persistImage(bitmap, "SP_Upload");

                    @Override
                    public void onCompleted(Exception e, JsonObject result) {

                    }
                });
    }

    private File persistImage(Bitmap bitmap, String name) {
        File filesDir = getApplicationContext().getFilesDir();
        File imageFile = new File(filesDir, name + ".jpg");

        OutputStream os;
        try {
            os = new FileOutputStream(imageFile);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os);
            os.flush();
            os.close();
        } catch (Exception e) {
            Log.e(getClass().getSimpleName(), "Error writing bitmap", e);
        }

        return imageFile;
    }

        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                    bitmap = BitmapFactory.decodeStream(inputStream);
                    imageView.setImageBitmap(bitmap);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();

登錄活動

     public class LoginActivity extends AppCompatActivity {

    private EditText email, password, id;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        email=findViewById(R.id.emailtext);
        password=findViewById(R.id.pwdtext);
        id=findViewById(R.id.clientid);
        Button loginBtn=findViewById(R.id.button);

        });
    }
}

您可以將 url 存儲在共享首選項中，並在每次執行上傳任務時檢索它，並將其設置在 .load() 方法上。

此外，您需要將圖像發送到您的服務器是一個多部分的帖子。 我沒有使用過 Ion，但我在 OkHttp 等其他庫中使用了 multipart，我復制了 Ion 文檔中出現的方法：

String dynamicUrl = PreferenceManager.getDefaultSharedPreferences(context).getString(CURRENT_SELECTED_URL, null);
File myImage = new File(myImagePath);

if(dynamicUrl != null) {
    Ion.with(getContext())
    .load(dynamicUrl)
    .uploadProgressBar(uploadProgressBar)
    .setMultipartParameter("goop", "noop")
    .setMultipartFile("myImageName", "image/*", myImage)
    .asJsonObject()
    .setCallback(...)
}
