所以我一直在尝试将包含base64编码图像的JSONObject发送到我用Flask制作的API,并且托管在测试网络服务器上。

            String imgData = Base64.encodeToString(data, Base64.DEFAULT);

            JSONObject jsonObj = new JSONObject();
            try{
                jsonObj.put("imgurl", imgData);

                sendPost(jsonObj);
                }
            catch (JSONException e){
                Context context2 = getApplicationContext();
                CharSequence text2 = "Bye toast!";
                int duration2 = Toast.LENGTH_SHORT;

                Toast toast2 = Toast.makeText(context2, text2, duration2);
                toast2.show();
            }
            try {
                Context connTe = getApplicationContext();
                CharSequence connectText = "Connection function successful";
                int connectDur = Toast.LENGTH_SHORT;

                Toast connectToast = Toast.makeText(connTe, connectText, connectDur);
                connectToast.show();

                URL url = new URL("http://BLABLABLA.pythonanywhere.com/image");
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setRequestMethod("POST");
                conn.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
                conn.setRequestProperty("Accept", "application/json");
                conn.setDoOutput(true);
                conn.setDoInput(true);

                Log.i("JSON", jsonObj.toString());
                DataOutputStream os = new DataOutputStream(conn.getOutputStream());
                //os.writeBytes(URLEncoder.encode(jsonParam.toString(), "UTF-8"));
                os.writeBytes(jsonObj.toString());

                os.flush();
                os.close();

                Log.i("STATUS", String.valueOf(conn.getResponseCode()));
                Log.i("MSG", conn.getResponseMessage());

                conn.disconnect();
            }
            catch (Exception a) {
                a.printStackTrace();
                }

但是当我查看日志时,甚至没有任何活动。 api正常工作,因为我多次使用Postman测试它。

我缺少什么?

编辑: 那里的祝酒词只是随机想要看到一些功能相关的东西,将被删除。
