localhost:5000打开index.html页,当我单击“提交”时,只有socketio可以工作,但是url未被更改。
import os
import requests
from flask import Flask,jsonify,render_template,request
from flask_socketio import SocketIO,emit,join_room,leave_room,send
from werkzeug import secure_filename
app = Flask(__name__)
app.config["SECRET_KEY"] = os.getenv("SECRET_KEY")
socketio=SocketIO(app)
@app.route("/")
def index():
return render_template("index.html")
@app.route("/chat" ,methods=["POST"])
def chat():
print("running chat")
return render_template("chat.html")
@socketio.on('join')
def on_join(data):
username = data['user']
room = data['room']
join_room(room)
emit('chat',{'username':username},room=room)
print("room has been allocated")
当我只在没有socketio的情况下执行url_for时,我能够更改路由,但现在似乎不起作用。在控制台和cmd中,我能够看到socketio正常工作,但是聊天路线不正常
