xmlrpc is still a feasible solution
I. environment
python3.6
II. Installation module
pip3 install grpcio pip3 install protobuf pip3 install grpcio-tools
3. Prepare grpc configuration file grpcdatabase.proto
Directory structure:
The contents are as follows:
syntax = "proto3"; package grpcServer; service Greeter { rpc GetSummary (Request) returns (Return) {} //Define the function to be called (GetSummary)+(Request) accept parameter + (Return) return parameter rpc GetSynonym (Request) returns (Return) {} } message Request { //Parameter data type string content = 1;//text int32 code=2; //Return status 0success; 1failed } message Return { //Return data type string message = 1;//text int32 code=2; //Return status 0success; 1failed } //Execute command + installation steps //python3 -m grpc_tools.protoc -I. --python_out=grpc_base_models/ --grpc_python_out=grpc_base_models/ grpcdatabase.proto
Compile: generate grpcatabase? Pb2.py? Grpcdatabase? PB2? Grpc.py file
python3 -m grpc_tools.protoc -I. --python_out=grpc_base_models/ --grpc_python_out=grpc_base_models/ grpcdatabase.proto
Write server code:

Write client code:
