| 35 | A command line tool to talk to any grpc server. |
| 36 | Example of talking to grpc interop server: |
| 37 | 1. Prepare request binary file: |
| 38 | a. create a text file input.txt, containing the following: |
| 39 | response_size: 10 |
| 40 | payload: { |
| 41 | body: "hello world" |
| 42 | } |
| 43 | b. under grpc/ run |
Yang Gao | 102eccb | 2015-06-16 00:43:25 -0700 | [diff] [blame^] | 44 | protoc --proto_path=test/proto/ \ |
| 45 | --encode=grpc.testing.SimpleRequest test/proto/messages.proto \ |
Yang Gao | ced2b89 | 2015-03-26 22:59:54 -0700 | [diff] [blame] | 46 | < input.txt > input.bin |
| 47 | 2. Start a server |
| 48 | make interop_server && bins/opt/interop_server --port=50051 |
| 49 | 3. Run the tool |
| 50 | make grpc_cli && bins/opt/grpc_cli call localhost:50051 \ |
| 51 | /grpc.testing.TestService/UnaryCall --enable_ssl=false \ |
| 52 | --input_binary_file=input.bin --output_binary_file=output.bin |
| 53 | 4. Decode response |
Yang Gao | 102eccb | 2015-06-16 00:43:25 -0700 | [diff] [blame^] | 54 | protoc --proto_path=test/proto/ \ |
| 55 | --decode=grpc.testing.SimpleResponse test/proto/messages.proto \ |
Yang Gao | ced2b89 | 2015-03-26 22:59:54 -0700 | [diff] [blame] | 56 | < output.bin > output.txt |
| 57 | 5. Now the text form of response should be in output.txt |
Yang Gao | 102eccb | 2015-06-16 00:43:25 -0700 | [diff] [blame^] | 58 | Optionally, metadata can be passed to server via flag --metadata, e.g. |
| 59 | --metadata="MyHeaderKey1:Value1:MyHeaderKey2:Value2" |
