尝试通过 Python 代码、本地主机和 Ngrok 将 Trading View 的警报 Webhook 连接到盈透证券时出错

Question

我正在尝试找到一些简单的设置来将交易从 TradingView 的警报发送到盈透证券。我已经设置了本地主机，运行了 ngrok，并且通过观看一些 YTB 视频创建了下面的代码。我还在交易视图的警报中添加了 webhook 的 URL。问题是每次出现警报时，我都会在 ngrok 中收到 500 内部服务器错误消息。并且交易不会执行。

**这是我尝试过的代码： **

`#imports
from datetime import datetime
from sanic import Sanic
from sanic import response
from ib_insync import *

#Create Sanic object called qpp
app = Sanic(__name__)
#app.ib = None
app.ctx.ib = None

#Create root / homepage
@app.route('/')
async def root(request):
return response.text('online')

#Listen for signals and submit BUY orders (webhook)
@app.route('/buy', methods=[ 'POST' ]) 
async def buy(request):
if request.method == 'POST':
#Check if we need to reconnect
await checkIfReconnect()
#Parse signal data
data = request.jason
order = MarketOrder('BUY', 0.00015)
contract = Crypto('BTC', 'PAXOS', 'USD')
trade = app.ib.placeOrder(contract,order)
#Wait for the order to be processed and check status
app.ctx.ib.sleep(1)
print(trade)

#Listen for signals and submit SELL orders (webhook)
@app.route('/sell', methods=[ 'POST' ]) 
async def sell(request):
if request.method == 'POST':
#Check if we need to reconnect
await checkIfReconnect()
#Parse signal data
data = request.jason
order = MarketOrder('SELL', 0.00015)
contract = Crypto('BTC', 'PAXOS', 'USD')
trade = app.ib.placeOrder(contract,order)
#Wait for the order to be processed and check status
app.ctx.ib.sleep(1)
print(trade)

#Reconnect to IB if connection is lost
async def checkIfReconnect():
if not app.ib.isDisconnected() or not app.ib.isConnected():
app.ib.disconnect()
app.ib = IB()
app.ib.connect('127.0.0.1',7496,clientId=1)

#Run app
if _name_ == '__main__':
#Connect to IB
app.ctx.ib = IB()
app.ctx.ib.connect('127.0.0.1',7496,clientId=1)
app.run(port=8080)`

**这是我得到的错误： ** { "description": "内部服务器错误", “状态”：500， "message": "应用程序遇到意外错误，无法继续。" }

**我还在终端中看到这些错误： **

ERROR:    Exception occurred while handling uri: 'http://MYURL/buy'
Traceback (most recent call last):

if TYPE_CHECKING:
                  
File "/Users/MYURL/#imports.py", line 26, in buy
await checkIfReconnect()
File "/Users/MYURL/#imports.py", line 56, in checkIfReconnect
if not app.ib.isDisconnected() or not app.ib.isConnected():
       ^^^^^^
AttributeError: 'Sanic' object has no attribute 'ib'

**我正在使用： **

MacOS High Sierra 10.13.6
Visual Studio Code Version: 1.85.2 (Universal)
Trader Workstation Version: Stable (10.19.2o) 20240612
Ngrok: 3.15.1

来自ngrok的PM在这里。根据错误，

Sanic

对象（

app

）没有

id

属性，根据文档它没有：https://sanic.readthedocs.io/en/stable/sanic /api/app.html#module-sanic.app
