RPC Client

• Each Client corresponds to one specific target/one specific cluster
• Each Client corresponds to one specific network communication protocol
• Each Client corresponds to one specific IDL

Sample

You can follow the detailed example below:

• Following the above example, the client is relatively simple and you can call the method directly.
• Use Example::XXXClient to create a client instance of some RPC. The IP+port or URL of the target is required.
• With the client instance, directly call the rpc function Echo. This is an asynchronous request, and the callback function will be invoked after the request is completed.

• For the usage of the RPC Context, please check RPC Context.

  #include <stdio.h>
  #include "example.srpc.h"
  
  using namespace srpc;
  
  int main()
  {
  Example::SRPCClient client("127.0.0.1", 1412);
  EchoRequest req;
  req.set_message("Hello, sogou rpc!");
  req.set_name("Li Yingxin");
  
  client.Echo(&req, [](EchoResponse *response, RPCContext *ctx) {
      if (ctx->success())
          printf("%s\n", response->DebugString().c_str());
      else
          printf("status[%d] error[%d] errmsg:%s\n",
                  ctx->get_status_code(), ctx->get_error(), ctx->get_errmsg());
  });
  
  pause();
  return 0;
  }
