【问题描述】：

我正在尝试将图像从 Android 上传到云存储。我正在关注this official guide，了解如何使用 JSON API 将文件上传到 Google Cloud Storage。这是我的代码

private class uploadImage extends AsyncTask<File, Void, String> {

    File file = mPhotoFile;

    private String delimiter = "--";

    @Override
    protected void onPreExecute() {
        Toast.makeText(getActivity(), mPhotoFile.getPath(), Toast.LENGTH_SHORT).show();
    }

    @Override
    protected String doInBackground(File... params) {


        try {
            URL url = new URL("https://www.googleapis.com/upload/storage/v1/b/backend-images/o?uploadType=media&name=myObject?key=my_key");
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

            urlConnection.setRequestMethod("POST");
            urlConnection.setChunkedStreamingMode(0);
            urlConnection.setRequestProperty("Content-Type", "image/jpeg");
            urlConnection.setRequestProperty("Content-Length", String.valueOf(mPhotoFile.getPath().getBytes().length));
            urlConnection.setRequestProperty("Authorization", "my_key");
            urlConnection.setDoOutput(true);
            urlConnection.setDoOutput(true);


            OutputStream out = new BufferedOutputStream(urlConnection.getOutputStream());
            InputStream responseStream = new BufferedInputStream(urlConnection.getInputStream());
            BufferedReader responseStreamReader = new BufferedReader(new InputStreamReader(responseStream));

            out.write(("Content-Type: image/jpeg\r\n").getBytes());
            out.write(("Content-Length: " + String.valueOf(mPhotoFile.getPath().getBytes().length)).getBytes());
            out.write("\r\n".getBytes());
            out.write(mPhotoFile.getPath().getBytes());
            out.write("\r\n".getBytes());

            String line = "";
            StringBuilder stringBuilder = new StringBuilder();

            while((line = responseStreamReader.readLine()) != null) {
                stringBuilder.append(line).append("\n");
            }

            String response = stringBuilder.toString();

            Log.i("CloudStorage", response);
        } catch (IOException e) {
            e.printStackTrace();
            return e.getMessage();
        }

        return "Everything was a success";
    }


}

我正在使用公共 API 访问方法并将 Api 密钥附加到链接（如 the guide says I could）以授权请求

这是我遇到的错误

我不知道这是客户端还是服务器端的问题

【问题讨论】：

?key=my_key 在您的真实代码中，这是分配了正确的值还是与此相同？
我编辑了，我有真正的钥匙

【解决方案1】：

做了一些改动后，我得到了它的工作。我收到 401 Unauthorized Error 代码，这意味着我没有访问存储桶的权限。

所以我没有附加查询参数key=api_key，而是附加了access_token=auth_token 来授权请求。

然后我向我的存储桶添加了allUsers 权限（将其公开以供所有人读写）并且它起作用了。
