/*
- A command line tool to talk to any grpc server.
+ A command line tool to talk to a grpc server.
Example of talking to grpc interop server:
- 1. Prepare request binary file:
- a. create a text file input.txt, containing the following:
- response_size: 10
- payload: {
- body: "hello world"
- }
- b. under grpc/ run
- protoc --proto_path=src/proto/grpc/testing/ \
- --encode=grpc.testing.SimpleRequest
- src/proto/grpc/testing/messages.proto \
- < input.txt > input.bin
- 2. Start a server
- make interop_server && bins/opt/interop_server --port=50051
- 3. Run the tool
- make grpc_cli && bins/opt/grpc_cli call localhost:50051 \
- /grpc.testing.TestService/UnaryCall --enable_ssl=false \
- --input_binary_file=input.bin --output_binary_file=output.bin
- 4. Decode response
- protoc --proto_path=src/proto/grpc/testing/ \
- --decode=grpc.testing.SimpleResponse src/proto/grpc/testing/messages.proto \
- < output.bin > output.txt
- 5. Now the text form of response should be in output.txt
- Optionally, metadata can be passed to server via flag --metadata, e.g.
- --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
+ grpc_cli call localhost:50051 UnaryCall src/proto/grpc/testing/test.proto \
+ "response_size:10" --enable_ssl=false
+
+ Options:
+ 1. --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.
+ 2. --metadata specifies metadata to be sent to the server, such as:
+ --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2"
+ 3. --enable_ssl, whether to use tls.
+ 4. --use_auth, if set to true, attach a GoogleDefaultCredentials to the call
+ 3. --input_binary_file, a file containing the serialized request. The file
+ 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.
+ 4. --output_binary_file, a file to write binary format response into, 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
