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)
- 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）
- 支持其它序列化协议
以下示例以使用protobuf序列化为例。其它序列化协议请参考demo。
- 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
from anthunder.discovery.mosn import MosnClient, ApplicationInfo
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
service_reg = MosnClient() # using mosn for service discovery, see https://mosn.io for detail
service_reg.startup(ApplicationInfo(YOUR_APP_NAME))
# service_reg = LocalRegistry({interface: (inf_ip, inf_port)}) # or a service-address dict as service discovery
# 订阅服务, subscribe before client's requests
service_reg.subscribe(interface)
client = AioClient(YOUR_APP_NAME, service_register=service_reg) # will create a thread, and send heartbeat to remote every 30s
interface = 'com.alipay.rpc.common.service.facade.pb.SampleServicePb:1.0'
# 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
