Question

我创建了一个Android应用程序，将图像从库上传到Firebase存储，我需要使用HttpPost上传图像。

我的代码如下：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent 
data) {
switch (requestCode) {
case TAKE_AVATAR_GALLERY_REQUEST:
if (resultCode == Activity.RESULT_OK) {
Uri photoUri = data.getData();
Bitmap avatar= Media.getBitmap(getContentResolver(), photoUri);
String strAvatarFilename = "avatar.jpg";
try {
 avatar.compress(CompressFormat.JPEG, 100,
 openFileOutput(strAvatarFilename, MODE_PRIVATE));
} catch (Exception e) {
Log.e(DEBUG_TAG, "Avatar compression and save failed.", e);
}

Uri imageUriToSaveCameraImageTo = Uri.fromFile(new File(
QuizSettingsActivity.this.getFilesDir(), strAvatarFilename));
Editor editor = mGameSettings.edit();
editor.putString(GAME_PREFERENCES_AVATAR, 
imageUriToSaveCameraImageTo.getPath());
editor.commit();

在doInBackground方法中，我调用postAvatarToServer，如下所示：

private boolean postAvatarToServer() {
    boolean succeeded = false;
    String avatar = mGameSettings.getString(GAME_PREFERENCES_AVATAR, "");
    MultipartEntity entity = new 
           MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    File file = new File(avatar);
    if (file.exists()) {
        FileBody encFile = new FileBody(file);
        entity.addPart("avatar", encFile);
        HttpPost request = new 
            HttpPost("https://firebasestorage.googleapis.com/v0/b/HERE I 
            WRITE THE FOLDER URL WITHOUT [gs://]/o/");
        request.setEntity(entity);
        HttpClient client = new DefaultHttpClient();
        try {
             HttpResponse response = client.execute(request);
             HttpEntity r_entity = response.getEntity();
            int statusCode = response.getStatusLine().getStatusCode();
            String responseString = null;
            if (statusCode == 200) {
                    responseString = EntityUtils.toString(r_entity);
            } else {
                    responseString = "Error occurred! Http Status Code: "
                                + statusCode;
            }
            succeeded = true;

        } catch (ClientProtocolException e) {
           Log.e(DEBUG_TAG, "Unexpected ClientProtocolException",e);
        } catch (IOException e) {
            Log.e(DEBUG_TAG, "Unexpected IOException", e);
        }
} else {
    Log.d(DEBUG_TAG, "No avatar to upload");
    succeeded = true;
            }
    return succeeded;

        }

在我得到的logcat中！发生了错误！ Http状态代码：400

那么错误在哪里以及如何解决它......

为什么不使用the existing Android SDK？

Uri file = Uri.fromFile(new File("path/to/local/file.jpg"));
StorageReference storageRef = storageRef.child("images/"+file.getLastPathSegment());
uploadTask = storageRef.putFile(file);

使用HttpPost将图像从Android图库上传到Firebase存储
