## Languages known issues

|
|
### Python
|
|
|
|
- Assert the type required in your server/client since python is able to receive `Bytes array` or `utf8 strings`.
|
|
|
|
```python
|
|
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`
|
|
|
|
```python
|
|
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 to `application/grpc+flatbuffers`
|
|
|
|
example: `.SayHello(ctx, b, grpc.CallContentSubtype("flatbuffers"))` |
