anthunder是一个python实现的BOLT协议库,提供BOLT client和server功能,支持使用BOLT + Protobuf方式的RPC调用。
- python3 >= 3.5 (aio classes needs asyncio support)
- python2.7 (limited support, needs extra 3rd party libraries)
- mosn >= 1.3 (to use with version >= 0.6)
- mosn < 1.3 (to use with version < 0.6)
- 支持Bolt+pb调用服务端(client端)
- 支持通过servicemesh的服务发现与服务发布
- 支持使用Bolt+pb提供服务(server端)
- 获取服务方提供的
.proto
文件 - 执行
protoc --python_out=. *.proto
命令,编译protobuf文件获得_pb2.py
文件 - 导入pb类并调用接口
from SampleServicePbResult_pb2 import SampleServicePbResult
from SampleServicePbRequest_pb2 import SampleServicePbRequest
from anthunder import AioClient
spanctx = ctx # ctx is transfered from upstream rpc, which is an object of mytracer.SpanContext, stores rpc_trace_context
# spanctx = SpanContext() # or generate a new context
client = AioClient(my_app_name) # will create a thread, and send heartbeat to mesh every 30s
interface = 'com.alipay.rpc.common.service.facade.pb.SampleServicePb:1.0'
# 订阅服务
client.subscribe(interface)
# 同步调用
content = client.invoke_sync(interface, "hello",
SampleServicePbRequest(name=some_name).SerializeToString(),
timeout_ms=500, spanctx=spanctx)
result = SampleServicePbResult()
result.ParseFromString(content)
# 异步调用
def client_callback(resp):
# callback function, accepts bytes as the only argument,
# then do deserialize and further processes
result = SampleServicePbResult()
result.ParseFromString(content)
# do something
future = client.invoke_async(interface, "hello",
SampleServicePbRequest(name=some_name).SerializeToString(),
spanctx=spanctx, callback=client_callback)
)
参考unittest
from anthunder.listener import aio_listener
class SampleService(object):
def __init__(self, ctx):
# service must accept one param as spanctx for rpc tracing support
self.ctx = ctx
def hello(self, bs: bytes):
obj = SampleServicePbRequest()
obj.ParseFromString(bs)
print("Processing Request", obj)
return SampleServicePbResult(result=obj.name).SerializeToString()
listener = aio_listener.AioListener(('127.0.0.1', 12200), "test_app")
# register interface and its function, plus its protobuf definition class
listener.handler.register_interface("com.alipay.rpc.common.service.facade.pb.SampleServicePb:1.0",
SampleService)
# start server in a standalone thread
listener.run_threading()
# or start in current thread
listener.run_forever()
# publish interfaces to service mesh
listener.publish()
# shutdown the server
listener.shutdown()
