如何在 Koush ion 中构建 URL

Question

我正在构建一个应用程序来将图像上传到我公司的服务器我正在使用 koush-ion 进行上传，现在我的问题是我必须根据通过编辑文本框在另一个 activity(LoginActivity) 中输入的信息动态更改要上传的 URL 我不知道该怎么做所以我想要发生的是客户输入他们的电子邮件、密码和 clientID（4 位数字）（在登录 Activity 中），应用程序使用它来构建 url 用于上传像这个（在相机Activity中） https://www.blahpractice.co.za/files-upload-ruben.asp?MyForm=Yes&ClientID=1234&Username=man@blahpractice.co.za&Pwd=BlahBlah123@

我从 koush github 那里得到了这个，我不确定这是否是我正在寻找的以及如何在 koush-ion[=16= 中实现来自另一个 activity 的数据]

Post application/x-www-form-urlencoded 并读取一个字符串

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

相机Activity

  public class CameraActivity extends AppCompatActivity implements 
   View.OnClickListener{
    private final int PICK_IMAGE = 12345;
    private final int REQUEST_CAMERA = 6352;
    private static final int REQUEST_CAMERA_ACCESS_PERMISSION =5674;
    private Bitmap bitmap;

    private ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera);
        imageView =findViewById(R.id.imageView);
        Button fromCamera=findViewById(R.id.fromCamera);
        Button fromGallery=findViewById(R.id.fromGallery);
        Button upload=findViewById(R.id.upload);
        upload.setOnClickListener(this);
        fromCamera.setOnClickListener(this);
        fromGallery.setOnClickListener(this);


        if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_ANY)) {
            fromCamera.setVisibility(View.GONE);
        }

    }

    @Override
    public void onClick(View view) {

        switch (view.getId()) {
            case R.id.fromCamera:
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
                        && ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA)
                        != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions(new String[]{Manifest.permission.CAMERA},
                            REQUEST_CAMERA_ACCESS_PERMISSION);
                }else {
                    getImageFromCamera();
                }
                break;
            case R.id.fromGallery:
                getImageFromGallery();
                break;
            case R.id.upload:
                if (bitmap != null)
                    uploadImageToServer();
                break;
        }

    }


    private void uploadImageToServer() {

我要在这里调用url

  File imageFile = persistImage(bitmap, "SP_Upload");
        Ion.with(this)
                .load("https://www.Blahpractice.co.za/files-upload-ruben.asp?MyForm=Yes")
                .setMultipartFile("SP-LOG", "image/jpeg", imageFile)
                .asJsonObject()
                .setCallback(new FutureCallback<JsonObject>() {
                    @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;
    }


    private void getImageFromCamera() {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(intent, REQUEST_CAMERA);
    }


    private void getImageFromGallery() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        if (intent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == PICK_IMAGE) {
            if (resultCode == Activity.RESULT_OK) {
                try {
                    InputStream inputStream = getContentResolver().openInputStream(data.getData());
                    bitmap = BitmapFactory.decodeStream(inputStream);
                    imageView.setImageBitmap(bitmap);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }

            }
        } else if (requestCode == REQUEST_CAMERA) {
            if (resultCode == Activity.RESULT_OK) {
                Bundle extras = data.getExtras();
                bitmap = (Bitmap) extras.get("data");
                imageView.setImageBitmap(bitmap);
            }
        }
    }


    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        if (requestCode == REQUEST_CAMERA_ACCESS_PERMISSION) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                getImageFromCamera();
            }
        } else {
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }
}

登录Activity

     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);

        loginBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String emailAddress=email.getText().toString().trim();
                String userPassword=password.getText().toString().trim();
                String clientId=id.getText().toString().trim();
                Intent intent=new Intent(LoginActivity.this, CameraActivity.class);
                intent.putExtra("clientId", clientId);
                intent.putExtra("email", emailAddress);
                intent.putExtra("password", userPassword);
                startActivity(intent);
            }
        });
    }
}

Answer 1

您可以将 url 存储在共享首选项中，并在每次执行上传任务时检索它并在 .load() 方法中设置它。

此外，将图像发送到服务器需要的是多部分 post。我没有使用过 Ion，但我在 OkHttp 等其他库中使用过 multipart，我复制了 Ion 文档中出现的方法：

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(...)
}
