trpc_attachment

Attachment Demo.

The server invocation relationship is as follows:

client <---> server

client send msg to server with attachment data.

Usage

We can use the following command to view the directory tree.

$ tree examples/features/trpc_attachment/
examples/features/trpc_attachment/
├── client
│   ├── BUILD
│   ├── client.cc
│   └── trpc_cpp_fiber.yaml
├── CMakeLists.txt
├── README.md
├── run_cmake.sh
├── run.sh
└── server
    ├── BUILD
    ├── demo_server.cc
    └── trpc_cpp_fiber.yaml

We can use the following script to quickly compile and run a program.

$ ./examples/features/trpc_attachment/run.sh

• Compilation

Run the following command to compile the client, proxy and server programs.

$ bazel build //examples/features/trpc_attachment/...

Alternatively, you can use cmake.

# build trpc-cpp libs first, if already build, just skip this build process.
$ mkdir -p build && cd build && cmake -DCMAKE_BUILD_TYPE=Release .. && make -j8 && cd -
# build examples/features/trpc_attachment
$ mkdir -p examples/features/trpc_attachment/build && cd examples/features/trpc_attachment/build && cmake -DCMAKE_BUILD_TYPE=Release .. && make -j8 && cd -

• Run the server program

Run the following commands to start the server program.

CMake build targets can be found at build of this directory, you can replace below server&client binary path when you use cmake to compile.

$ ./bazel-bin/examples/features/trpc_attachment/server/demo_server --config=./examples/features/trpc_attachment/server/trpc_cpp_fiber.yaml

• Run the client program

Run the following command to start the client program.

$ ./bazel-bin/examples/features/trpc_attachment/client/client --client_config=./examples/features/trpc_attachment/client/trpc_cpp_fiber.yaml

The content of the output from the client program is as follows:

response: msg: "hello, attachment msg"

response attachment: return attachment data
