为什么下面的 Couchbase async Python 代码不起作用?
Why following Couchbase async Python code does not work?
考虑以下代码:
import asyncio
from acouchbase.cluster import Cluster
from couchbase.cluster import ClusterOptions
from couchbase.cluster import PasswordAuthenticator
async def do_crud_op():
cb = Cluster.connect("couchbase://localhost", options=ClusterOptions(PasswordAuthenticator("user", "password")))
cb = cb.bucket('customers')
await cb.upsert('id', {'some': 'value'})
return await cb.get('id')
loop = asyncio.get_event_loop()
rv = loop.run_until_complete(do_crud_op())
print(rv.value)
我在 Ubuntu 20.04 上使用 Python 3.0 SDK 和 COuchbase 6.5.1。上面的代码给了我 LCB_ERR_NO_CONFIGURATION
异常。有人可以帮忙吗?
好吧,我发现我们需要使用 on_connect
方法等待存储桶变量使其工作。
import asyncio
from acouchbase.cluster import Cluster
from couchbase.cluster import ClusterOptions
from couchbase.cluster import PasswordAuthenticator
async def do_crud_op():
cb = Cluster.connect("couchbase://localhost", options=ClusterOptions(PasswordAuthenticator("user", "password")))
cb = cb.bucket('customers')
await cb.on_connect()
await cb.upsert('id', {'some': 'value'})
return await cb.get('id')
loop = asyncio.get_event_loop()
rv = loop.run_until_complete(do_crud_op())
print(rv.value)
