[英]Managing authentication session between Android and Flask-SocketIO
[英]flask-socketio doesn't allow connection from android device
好的,所以我將按照這些教程來使用flask-socketIO和適用於android設備的客戶端應用程序來構建socketIO服務器。 我的python設置非常簡單:
Python服務器:
init.py:
from flask import Flask, render_template
from flask.ext.socketio import SocketIO, emit
import logging
from os import getcwd
from datetime import datetime
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)
def openDir(folder):
import os, errno
try:
os.makedirs(folder)
except OSError, e:
if e.errno != errno.EEXIST:
raise
openDir('logs')
def fileAndChannelLogger(file_location,name):
logger = logging.getLogger(name)
logger.setLevel(logging.DEBUG)
fh = logging.FileHandler("".join([getcwd(),'/',file_location,'/',datetime.today().strftime("%Y%m%d_%H_%M"),"_",name,".log"]))
fh.setLevel(logging.DEBUG)
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s - %(levelname)s | %(message)s')
fh.setFormatter(formatter)
ch.setFormatter(formatter)
logger.addHandler(fh)
logger.addHandler(ch)
return logger
logger = fileAndChannelLogger('logs', 'test')
@app.route('/')
def index():
logger.debug("Someone accessed the root page")
return render_template('index.html')
@socketio.on('connect', namespace='/test')
def test_connect():
logger.debug('Client connected')
@socketio.on('new message', namespace='/test')
def new_message(message):
logger.debug(message)
@socketio.on('disconnect', namespace='/test')
def test_disconnect():
logger.debug('Client disconnected')
run.py
from app import app, socketio
if __name__ == '__main__':
socketio.run(app,host='My_cool_host_name')
Android客戶端:
MainActivity.java
import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import java.net.URISyntaxException;
import java.util.Objects;
import com.github.nkzawa.emitter.Emitter;
import com.github.nkzawa.socketio.client.IO;
import com.github.nkzawa.socketio.client.Socket;
import org.json.JSONException;
import org.json.JSONObject;
import static android.app.PendingIntent.getActivity;
public class MainActivity extends Activity implements View.OnClickListener {
EditText userID;
EditText statement;
private Socket mSocket;
{
try {
mSocket = IO.socket("http://My_cool_host_name:5000/test");
} catch (URISyntaxException e) {}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSocket.connect();
Button send = (Button) findViewById(R.id.sendBtn);
send.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
String ID_data = userID.getText().toString();
String statement_data = statement.getText().toString();
if (TextUtils.isEmpty(ID_data)) {
return;
}
if (TextUtils.isEmpty(statement_data)) {
return;
}
statement.setText("");
JSONObject json = new JSONObject();
try {
json.put("user",ID_data);
} catch (JSONException e) {
e.printStackTrace();
}
try {
json.put("statement",statement_data);
} catch (JSONException e) {
e.printStackTrace();
}
mSocket.emit("new message",json);
}
}
基本上,它需要兩個編輯框,然后將信息傳遞給服務器,沒有什么花哨的花哨之處,僅足以獲得所有工作原理的基礎。 我啟動服務器,當我轉到具有指定端口的地址時,可以從瀏覽器中看到index.html,當我在模擬設備中運行客戶端應用程序時,我會在控制台中收到此錯誤:

如您所見,它說明了
您需要使用gevent-socketio服務器。
但是我想我可以像這樣運行它,是否需要為了這個簡單的測試而將其轉入gevent-socketio服務器后面? 如果可以,可以推薦一個方向嗎? 這些是我安裝的python庫:

任何幫助將不勝感激,謝謝。
可悲的是,我也遇到同樣的問題,不知道如何解決。 在這里等待答案時,我嘗試了另一個庫https://github.com/koush/AndroidAsync ,幸運的是它可以工作。 也許您可以嘗試一下。
我有一個類似的問題,它與與Android通信時flask-socketio使用的編碼有關。 嘗試:
mSocket = IO.socket("http://My_cool_host_name:5000/test?b64=1");
