Question

您好，我正在尝试通过websocket将数据js发送到django，但无法正常工作。您能帮我哪里做错了吗？

ps：我能够将数据从服务器发送到客户端

错误：

提高ValueError（“传入的WebSocket框架没有文本部分！”）

传入的WebSocket框架没有文本部分！

WebSocket断开连接/ ws / [127.0.0.1:64282]

js

document.addEventListener('DOMContentLoaded', function () {
        let webSocketBridge = new WebSocket("ws://127.0.0.1:8000/ws/");

        webSocketBridge.onopen = function(action) {
            console.log(action);
            webSocketBridge.send(JSON.stringify({
                "id": "client1"
            }));

        };

        webSocketBridge.onmessage = function(event) {
           let message = event.data;
            as += message + "\r\n";
            $('#messages').html(as);

        };

consumer.py

import asyncio
from channels.generic.websocket import AsyncJsonWebsocketConsumer

class TickTockConsumer(AsyncJsonWebsocketConsumer):
    async def connect(self):
        await self.accept()

        while 1:
            await asyncio.sleep(0.1)
            await self.send_json("tick")
            await asyncio.sleep(0.1)
            await self.send_json(".......tock")
            await self.receive()

我找到了


import Web3 from 'web3';

const web3 = new Web3(window.web3.currentProvider);

export default web3;

或带有异步json

class TickTockConsumer(WebsocketConsumer):
    def connect(self):
        self.accept()
        self.send("tick")
        self.send(".......tock")

    def receive(self, text_data):
        print(text_data)
