Fluent Assertions Faces Backlash After Abandoning Open Source Licensing
Fluent Assertions is facing backlash after dropping the Apache license for a commercial model, leaving users blindsided and questioning contributor rights.
Micro-Framwork for gRPC with REST expose support.
pip install cygrpc
git+https://github.com/cuemby/python-cygrpc.git#egg=cygrpc
Params:
if you decide used all values by default, you can setup the server in less lines
from cygrpc.server import Server
server = Server()
server.add_service(calculator_api_pb2_grpc, ServiceImpl)
server.start()
Example using all params:
from cygrpc.server import Server
# Initialization of server definition, 'host', 'port', 'max_threads' has be optionals.
# By default the __init__ function set the same values. if don't you wanna set interceptors only remove the param
server = Server(host="0.0.0.0", port=50051, max_threads=10, interceptors=(MyAuthInterceptor(),))
# attach service to server, repeat for multiple services
server.add_service(calculator_api_pb2_grpc, ServiceImpl)
# finally start server.
server.start()
The implementation is the same.
# import rest decorator
from cygrpc.gateway.http import rest
class ServiceImpl(calculator_api_pb2_grpc.CalculatorAPIServicer):
"""
Service logic implementation.
"""
def Sum(self, request, context):
total = 0
for addend in request.addends:
total += addend
response = pb.SumResponse(sum=total)
return response
for add rest route add the decorator @rest to method definition:
# import rest decorator
from cygrpc.gateway.http import rest
class ServiceImpl(calculator_api_pb2_grpc.CalculatorAPIServicer):
"""
Service logic implementation.
"""
@rest("/v1/calculator/sum", method="POST")
def Sum(self, request, context):
total = 0
for addend in request.addends:
total += addend
response = pb.SumResponse(sum=total)
return response
from cygrpc.middleware import CyGrpcInterceptor
class CustomInterceptor(CyGrpcInterceptor):
def intercept_service(self, continuation, handler_call_details):
# for continue to method implementation
return self.on_success(continuation, handler_call_details)
# for terminate request
return self.on_failed(grpc.StatusCode.UNAUTHENTICATED, "Validate authentication failed.")
from cygrpc.middleware.auth import CyGrpcAuthInterceptor
class MyAuthInterceptor(CyGrpcAuthInterceptor):
def auth_process(self, continuation, handler_call_details):
""""
..... my auth validation process ....
"""
return True
