# aio-nameko-proxy
A standalone nameko rpc proxy for asyncio and some wrappers for using nameko rpc proxy with asynchronous web frameworks(Sanic, fastapi).
This project is based on aio-pika and reference the source code of official nameko project and aio-pika.
### install
```shell
pip install aio-nameko-proxy
```
### examples:
#### standalone AIOClusterRpcProxy
If you want most of your messages to be persistent(default). Set the delivery mode parameter as
DeliveryMode.PERSISTENT, Call sw_dlm_call when you need to send a non-persistent message.
```python
import ssl
import asyncio
from aio_nameko_proxy import AIOClusterRpcProxy
from aio_pika import DeliveryMode
config = {
"AMQP_URI": "amqp://guest:guest@127.0.0.1:5672", # Required,
"rpc_exchange": "nameko-rpc",
"time_out": 30,
"con_time_out": 5,
"delivery_mode": DeliveryMode.PERSISTENT,
"serializer": "my_serializer",
"ACCEPT": ["pickle", "json", "my_serializer"],
"SERIALIZERS": {
"my_serializer": {
"encoder": "my_slizer.dumps",
"decoder": "my_slizer.loads",
"content_type": "my-content-type",
"content_encoding": "utf-8"
}
},
# If SSL is configured, Remember to change the URI to TLS port. eg: "amqps://guest:guest@127.0.0.1:5671"
"AMQP_SSL": {
'ca_certs': 'certs/ca_certificate.pem', # or 'cafile': 'certs/ca_certificate.pem',
'certfile': 'certs/client_certificate.pem',
'keyfile': 'certs/client_key.pem',
'cert_reqs': ssl.CERT_REQUIRED
}
}
async def run():
async with AIOClusterRpcProxy(config) as rpc:
# time_out: the time_out of waitting the remote method result.
# con_time_out: the time_out of connecting to the rabbitmq server or binding the queue, consume and so on.
# persistent msg call
result = await rpc.rpc_demo_service.normal_rpc("demo")
reply_obj = await rpc.rpc_demo_service.normal_rpc.call_async("demo")
result = await reply_obj.result()
# non-persistent msg call
result = await rpc.rpc_demo_service.normal_rpc.sw_dlm_call("demo")
reply_obj = await rpc.rpc_demo_service.normal_rpc.sw_dlm_call_async("demo")
result = await reply_obj.result()
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
```
If you want most of your messages to be non-persistent(persistent is default). Set the delivery mode parameter as
DeliveryMode.NOT_PERSISTENT, Call sw_dlm_call when you need to send a persistent message.
```python
import asyncio
from aio_nameko_proxy import AIOClusterRpcProxy
from aio_pika import DeliveryMode
config = {
"AMQP_URI": "pyamqp://guest:guest@127.0.0.1:5672",
"rpc_exchange": "nameko-rpc",
"time_out": 30,
"con_time_out": 5,
"delivery_mode": DeliveryMode.NOT_PERSISTENT
}
async def run():
async with AIOClusterRpcProxy(config) as rpc:
# non-persistent msg call
result = await rpc.rpc_demo_service.normal_rpc("demo")
reply_obj = await rpc.rpc_demo_service.normal_rpc.call_async("demo")
result = await reply_obj.result()
# persistent msg call
result = await rpc.rpc_demo_service.normal_rpc.sw_dlm_call("demo")
reply_obj = await rpc.rpc_demo_service.normal_rpc.sw_dlm_call_async("demo")
result = await reply_obj.result()
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
```
#### AIOPooledClusterRpcProxy
```python
import asyncio
from aio_nameko_proxy import AIOPooledClusterRpcProxy
from aio_pika import DeliveryMode
config = {
"AMQP_URI": "pyamqp://guest:guest@127.0.0.1:5672",
"rpc_exchange": "nameko-rpc",
"time_out": 30,
"con_time_out": 5,
"pool_size": 10,
"initial_size": 2,
"delivery_mode": DeliveryMode.NOT_PERSISTENT
}
async def run():
async with AIOPooledClusterRpcProxy(config) as proxy_pool:
async with proxy_pool.acquire() as rpc:
result = await rpc.rpc_demo_service.normal_rpc("demo")
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
```
#### Sanic Wrapper
