如何修复在本地服务器上正常运行但部署到AWS后无法运行的程序？

如何解决如何修复在本地服务器上正常运行但部署到AWS后无法运行的程序？

我对编程比较了解，尤其是在通过亚马逊Web服务运行发布请求和使用API​​请求方面遇到的问题。

我目前在下面编写了一个程序。

from chalice import Chalice
import requests,json
import alpaca_Trade_api as Tradeapi
app = Chalice(app_name='Tradingview-webhook-alerts')
API_KEY = 'API'
SECRET_KEY = 'SECRET'
BASE_URL = "https://paper-api.alpaca.markets"
ORDERS_URL = "{}/v2/orders".format(BASE_URL)
HEADERS = {'APCA-API-KEY-ID': API_KEY,'APCA-API-secret-key': SECRET_KEY}

@app.route('/GDX',methods=['POST'])
def GDX():
    request = app.current_request
    webhook_message = request.json_body
    
    p = 1-(webhook_message['close'] / webhook_message['high'])
    if p<.0175: #if the high price for the 15m candle is 3% higher than the close,thee excution will not occur
        data = {
        "symbol": webhook_message['ticker'],#want it to access whatever the payload message is,payload message I believe is what the alert from Trading_View will send
        "qty": 8,"side": "buy","type": "limit","limit_price": webhook_message['close'],"time_in_force": "gtc","order_class": "bracket",#need to find out the average max profit per Trade
        "take_profit": {
        "limit_price": webhook_message['close'] * 1.0085 #take 0.6%% profit
        },"stop_loss": {
            "stop_price": webhook_message['close'] * 0.95,#stop loss of 6%
            "limit_price": webhook_message['close'] * 0.93
        }
        }
        r = requests.post(ORDERS_URL,json=data,headers=HEADERS)   

        response = json.loads(r.content)
        print(response)
        print(p)

        return {
        'message': 'I bought the stock!','webhook_message': webhook_message
        }
    else:
        return{
            'message': 'stock not purchased','webhook_message': webhook_message
        }

@app.route('/buy_SLV',methods=['POST'])
def buy_stock():
    request = app.current_request
    webhook_message = request.json_body
    
    data = {
    "symbol": webhook_message['ticker'],payload message I believe is what the alert from Trading_View will send
    "qty": 4,"take_profit": {
    "limit_price": webhook_message['close'] * 1.008 #take 1% profit
    },"stop_loss": {
        "stop_price": webhook_message['close'] * 0.95,#stop loss of 2%
        "limit_price": webhook_message['close'] * 0.94
    }
}

    r = requests.post(ORDERS_URL,headers=HEADERS)   

    response = json.loads(r.content)
    print(response)
    print(response.keys())

    return {
        'message': 'I bought the stock!','webhook_message': webhook_message
    }

@app.route('/GDX_UpperBB',methods=['POST'])
def GDX_UpperBB():
    request = app.current_request
    webhook_message = request.json_body

    api = Tradeapi.REST(API_KEY,SECRET_KEY,base_url=BASE_URL)
    ids = []

    orders = api.list_orders(
    limit=100,nested=True  # show nested multi-leg orders
    )
    
    GDX_orders = [o for o in orders if o.symbol == 'GDX']
    for i in GDX_orders:
        ids.append(i.id)
        if len(orders)>0:
            print(ids)
            for i in ids:
                api.cancel_order(i)
        else:
            print('there are no orders')

    return{
        'message': 'I bought the stock!','webhook_message': webhook_message
    }

前两种方法运行良好（通过AWS和在本地服务器上）。第三种方法（GDX_UpperBB）是什么导致一切停止工作。当我在本地服务器上运行该程序并调用GDX_UpperBB方法时，它的执行没有问题。但是当我通过chalice通过亚马逊网络服务API部署程序时，得到了502 BadGateway响应，并返回了"message": "Internal server error"。

当我进入AWS并测试方法时，这是我得到的控制台响应（我删除了响应的前半部分，因为响应时间很长，并且所有内容都说运行成功了）

感谢所有帮助。

解决方法

您需要将依赖项添加到requirements.txt文件管理器中，或将代码添加到主项目目录之外的供应商目录中
