Leverage reflection to interact with GRPC in a familiar manner for users of the requests library.
from grpc_requests import Client
client = Client.get_by_endpoint("localhost:50051")
assert client.service_names == ["helloworld.Greeter"]
request_data = {"name": "sinsky"}
say_hello_response = client.request("helloworld.Greeter", "SayHello", request_data)
assert say_hello_response == {"message":"Hello sinsky!"}
pip install grpc_requests
In short:
Instantiate a client using the URL of a GRPC server and any authentication credentials you may need. If the server utilizes SSL (and it probably does) make sure to toggle that flag.
from grpc_requests import Client
metadata = [("authorization", "bearer my.cool.jwt")]
client = Client.get_by_endpoint("cool.servers.arecool:443", ssl=True, metadata=metadata)
The examples page provides more thorough examples of usage scenarioes, and the unit tests are also a useful reference point.
Contributions from the community are welcomed and greatly appreciated.
Before opening a PR, running python -m nox can be used to ensure the contribution passes
linting and unit test checks for all supported versions of Python and protobuf.
You can also run complexity.sh to use
radon to look at the cyclomatic complexity,
maintainability index, and Halstead effort and difficulty of files.
PRs should be targeted to merge with the develop branch. When opening a PR,
please assign it to a maintainer for review. The maintainers will take it from
there.
grpc_requests currently does its best to support versions of Python and
protobuf that are within their support lifetimes. You may find that other versions
of dependencies work with the library, but this should be treated as a happy accident.
For Python, we target versions that are in the security and bugfix phases. For protobuf, we target versions that in their public support phase.
Python's support matrix Protobuf's support matrix
The maintainers of grpc_requests have found that protobuf 4.25.4 is not compatible
with verisons >=1.66.0 of both grpcio and grpcio-reflection. If your use case
needs 4.25.4 of protobuf, we recommend sticking to verison 1.65.x of grpcio and
grpcio-reflection.
The maintainers have also noted that under Python 3.13 grpc_requests will work
only with protobuf version 5.29.4 and above.
