Question

我尝试通过Java创建的webservice上传视频。有时也发送视频，但有时服务器返回＆＃34; 400错误，参数错误＆＃34;

你们有人可以帮助我吗？

    private class SendVideoTask extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {
        try {

            final String url = server_url + "/rest/cloud/uploadFilePost";
            Form form = new Form();
            form.add("test_id", test_id);
            form.add("report_id", report_id);

            String encoded_file = cc.encodeFileToBase64Binary(mediaFile);
            form.add("encoded_file", encoded_file);
            String resp = "";
            CloseableHttpClient httpclient = HttpClients.createSystem();

            HttpPost httppost = new HttpPost(url);

            List<NameValuePair> urlParameters = new ArrayList<NameValuePair>();

            urlParameters.add(new BasicNameValuePair("test_id", test_id));
            urlParameters.add(new BasicNameValuePair("report_id", String
                    .valueOf(report_id)));
            urlParameters.add(new BasicNameValuePair("encoded_file",
                    encoded_file));

            httppost.setEntity(new UrlEncodedFormEntity(urlParameters));

            CloseableHttpResponse response = httpclient.execute(httppost);

            try {

                HttpEntity entity = response.getEntity();

                if (entity != null) {

                    InputStream instream = entity.getContent();
                    try {

                        resp = EntityUtils.toString(entity);

                    } finally {
                        instream.close();
                    }

                }

            } finally {
                response.close();
                httpclient.getConnectionManager().shutdown();
            }

            return resp;

        } catch (Exception e) {
            Log.e("VideoAsyncTask (Background)", e.getMessage(), e);
            // Toast.makeText(getApplicationContext(),
            // "ERROR: " + e.getMessage(), Toast.LENGTH_LONG).show();
        }

        return null;
    }
}
