如何使用sentry处理fastapi错误

Question

我有以下函数，我正在尝试处理错误，并将其发送给哨兵

import sentry_sdk
...
...
...
def create_orders(
orders: orders_schema.OrderCreate
):
try:
query = "INSERT INTO orders VALUES (nextval('orders_id_seq'), :price, :currency, :created_on, :note)"
values = {
"price": orders.price,
"currency": orders.currency,
"created_on": datetime.utcnow(),
"note": orders.note
}
except Exception as err:
sentry_sdk.capture_exception(err)
return database.execute(query, values=values)

这是调用函数的路由器端点

@router.post("/orders/create", response_model=orders_schema.OrderCreate)
async def create_new_order(
orders: orders_schema.OrderCreate
):
await crud.create_orders(orders)
return {**orders.dict()}

Sentry集成的工作原理就像我测试接收其他一些未处理的错误事件一样，但现在我想实际使用Sentry来满足我的需要；这是为了帮助管理已处理的错误

但是，当我试图向api端点发送错误的值或错误的密钥时，不会向sentine 发送任何内容

我是不是遗漏了什么，或者我该怎么做才能发送错误？

Answer 1

捕获sentry错误的行可能永远不会被执行，因为对DB的访问是在return语句上。。。换言之，try/except块中的内容没有失败，因此except没有运行，然后代码转到可能失败的返回行，但此时哨兵不再捕获

Answer 2

def create_orders(
orders: orders_schema.OrderCreate
):
try:
result = None
query = "INSERT INTO orders VALUES (nextval('orders_id_seq'), :price, :currency, :created_on, :note)"
values = {
"price": orders.price,
"currency": orders.currency,
"created_on": datetime.utcnow(),
"note": orders.note
}
result = database.execute(query, values=values)
except Exception as err:
sentry_sdk.capture_exception(err)
finally:
return result

您可以直接引发错误：

from fastapi import FastAPI, HTTPException
@router.post("/orders/create", response_model=orders_schema.OrderCreate)
async def create_new_order(orders: orders_schema.OrderCreate):
try:
await crud.create_orders(orders)
return {**orders.dict()
except Exception as e:
raise HTTPException(status_code=400,detail=e)
