grpc_requests

GRPC for Humans
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!"}

Features

Create a client easily when connecting to servers implementing grpc reflection
Still support creating a client from stubs when reflection isn't available
All unary and stream methods supported
TLS and compression connections supported
AsyncIO API supported

Install
pip install grpc_requests

Usage
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.
Contributing
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.
Compatibility
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.

ChangeLog
All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog,
and this project adheres to Semantic Versioning.
0.1.20 - 2024-08-15
Added

Noxfile for testing combinations of supported versions Python and protobuf
Specifications around support targets for Python and protobuf for the library

Fixed

Fixed a bug wherein attempting to retrieve a dependency of a FileDescriptor could
result thrown an exception if the dependency was not being served via reflection by
the server.

0.1.19 - 2024-07-18
Added

Tools for developers to measure complexity of the code base
Integrations with mypy

Removed
Support for Python 3.7
0.1.18 - 2024-05-18
Added

Support for lazy loading of services in async clients

0.1.17 - 2024-04-22
Added

Support for custom message parsing in both async and sync clients

Removed

Removed singular FileDescriptor getter methods and Method specific field descriptor
methods as laid out previously.

0.1.16 - 2024-03-03
Added

Additional usage examples

Fixed

Put deprecation warnings in the correct place for old get_descriptor methods, so they do not warn at all times.

0.1.15 - 2024-02-17
Added

Add methods to return FileDescriptors and their transistive dependencies as requested by either a name or symbol

Deprecated

Due to the possibility of transient dependencies being missed, or other name or symbol collisions, methods to access singular FileDescriptors are deprecated and will be removed in version 0.1.17
The method to retrieve fields of a method's descriptor input type alone will be removed in version 0.1.17

0.1.14 - 2024-01-06

Added

Added channel interceptors for standard and async clients

Fixed

Refactored how methods and services are added to description pool to better avoid cases where FileDescriptors may be added twice.

Added

Method to print out a generic descriptor added to utils collection
Helper methods to print out a method's request and responses in a human readable format
