ubuntu|grpc安装与简单demo测试 ubuntu|grpc

grpc安装：
由于工作需要，最近在学google的rpc开源框架；由于本人菜鸟一枚，而且是从Windows开发转到Linux；由于之前版本控制使用的是svn，没有使用过git，所以从GitHub上下载代码是通过浏览器下载zip格式的压缩文件，折腾了好几天了，发现了各种坑，各种缺少库，各种不知道怎么把这个库给装机器上。对于一个不熟悉Linux的人来说，这个体验简直糟糕透了。没办法了又在机器上装了git，按照下面这个链接从新安装，但惊喜就这么发生了，特么的居然可以安装上grpc！！！
grpc安装请参考该链接：https://blog.csdn.net/u012023606/article/details/54584282
其中有个文件我改了一下，因为之前装的时候碰到过缺少openssl这个库

上述链接中的Makefile文件第10行有问题，由于本人菜鸟，不知该怎么修改，故从githum上下载来的代码中的hello例子中拷贝了一个makefile过来并简单修改了一下。
example.proto：

syntax = "proto3"; message SearchRequest { string Request = 1; }message SearchResponse { string Response = 2; }service SearchService { rpc Search (SearchRequest) returns (SearchResponse); }

client.cpp：

#include #include #include#include #include #include "example.grpc.pb.h"using grpc::Channel; using grpc::ClientAsyncResponseReader; using grpc::ClientContext; using grpc::CompletionQueue; using grpc::Status; class ExampleClient { public: explicit ExampleClient(std::shared_ptr channel) : stub_(SearchService::NewStub(channel)) {}std::string Search(const std::string& user) { SearchRequest request; request.set_request(user); SearchResponse reply; ClientContext context; CompletionQueue cq; Status status; std::unique_ptr rpc( stub_->AsyncSearch(&context, request, &cq)); rpc->Finish(&reply, &status, (void*)1); void* got_tag; bool ok = false; GPR_ASSERT(cq.Next(&got_tag, &ok)); GPR_ASSERT(got_tag == (void*)1); GPR_ASSERT(ok); if (status.ok()) { return reply.response(); } else { return "RPC failed"; } }private: std::unique_ptr stub_; }; int main(int argc, char** argv) { ExampleClient client(grpc::CreateChannel( "localhost:50051", grpc::InsecureChannelCredentials())); std::string user("world"); std::string reply = client.Search(user); // The actual RPC call! std::cout << "client received: " << reply << std::endl; return 0; }

server.cpp：

#include #include #include#include #include #include #include #include #include "example.grpc.pb.h"using grpc::Server; using grpc::ServerBuilder; using grpc::ServerContext; using grpc::Status; class SearchRequestImpl final : public SearchService::Service { Status Search(ServerContext* context, const SearchRequest* request, SearchResponse* reply) override { std::string prefix("Hello "); reply->set_response(prefix + request->request()); return Status::OK; } }; void RunServer() { std::string server_address("0.0.0.0:50051"); SearchRequestImpl service; ServerBuilder builder; builder.AddListeningPort(server_address, grpc::InsecureServerCredentials()); builder.RegisterService(&service); std::unique_ptr server(builder.BuildAndStart()); std::cout << "Server listening on " << server_address << std::endl; server->Wait(); }int main(int argc, char** argv) { RunServer(); return 0; }
