* Keep methods with struct name and switch them to default This PR can help fix the following two issues: 1): A set of simplified API (without struct name) was added in https://github.com/google/flatbuffers/pull/6336. It causes name conflict when merging all generated python file into a single one (the primary usage senario in Google). 2): Flatbuffers 2.0 generates absolute import path, which may cause name space conflicts. See more details in https://github.com/google/flatbuffers/issues/5840. The solution for both is to generate the merged Python code, similar C++. The merged code will not contain the simplied API, but only the method with struct name. For issue (1), it will mimic the exactly usage pattern for Google internal. For issue (2), users can generate the merged flatbuffer code, without worrying about the imports. The above idea will be implemented in the following steps: Step 1 (this PR): revert changes in https://github.com/google/flatbuffers/pull/6336 that set the simplified API as default. Remove statements that the original API will be deprecated, and reset the original API as default. Step 2 (the following PR): create a flag to generate the merged code. The Simplified API will be removed from the merged code, otherwise it will cause name conflict. * Update the generated sample code * Update the generated example code * Reverst the changes of GetRootAs * Update examples from grpc/example/generate.sh |

Python
- Assert the type required in your server/client since python is able to receive
Bytes array
orutf8 strings
.
def SayHello(self, request, context):
# request might be a byte array or a utf8 string
r = HelloRequest.HelloRequest().GetRootAs(request, 0)
reply = "Unknown"
if r.Name():
reply = r.Name()
# Issues might happen if type checking isnt present.
# thus encoding it as a `reply.decode('UTF-8')`
return build_reply("welcome " + reply.decode('UTF-8'))
This can be prevented by making sure all the requests coming to/from python are Bytes array
def say_hello(stub, builder):
hello_request = bytes(builder.Output())
reply = stub.SayHello(hello_request)
r = HelloReply.HelloReply.GetRootAs(reply)
print(r.Message())
Go
- Always requires the
content-type
of the payload to be set toapplication/grpc+flatbuffers
example: .SayHello(ctx, b, grpc.CallContentSubtype("flatbuffers"))
