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;
