/*
A command line tool to talk to a grpc server.
Run `grpc_cli help` command to see its usage information.
Example of talking to grpc interop server:
grpc_cli call localhost:50051 UnaryCall "response_size:10" \
--protofiles=src/proto/grpc/testing/test.proto --enable_ssl=false
Options:
1. --protofiles, use this flag to provide proto files if the server does
does not have the reflection service.
2. --proto_path, if your proto file is not under current working directory,
use this flag to provide a search root. It should work similar to the
counterpart in protoc. This option is valid only when protofiles is
provided.
3. --metadata specifies metadata to be sent to the server, such as:
--metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
4. --enable_ssl, whether to use tls.
5. --use_auth, if set to true, attach a GoogleDefaultCredentials to the call
6. --infile, input filename (defaults to stdin)
7. --outfile, output filename (defaults to stdout)
8. --binary_input, use the serialized request as input. The serialized
request can be generated by calling something like:
protoc --proto_path=src/proto/grpc/testing/ \
--encode=grpc.testing.SimpleRequest \
src/proto/grpc/testing/messages.proto \
< input.txt > input.bin
If this is used and no proto file is provided in the argument list, the
method string has to be exact in the form of /package.service/method.
9. --binary_output, use binary format response as output, it can
be later decoded using protoc:
protoc --proto_path=src/proto/grpc/testing/ \
--decode=grpc.testing.SimpleResponse \
src/proto/grpc/testing/messages.proto \
< output.bin > output.txt
