为了依赖的成功安装,采用gitee进行下载与更新。记得需要安装git软件。
安装命令:
在自己指定的目录下,鼠标右键,选择 git Bash Here
打开命令行
git clone -b v1.34.0 https://gitee.com/mirrors/grpc-framework.git grpc
在grpc的目录下修改配置文件:.gitmodules
复制下面内容替换.gitmodules内容:
[submodule "third_party/zlib"]
path = third_party/zlib
#url = https://github.com/madler/zlib
url = https://gitee.com/mirrors/zlib.git
# When using CMake to build, the zlib submodule ends up with a
# generated file that makes Git consider the submodule dirty. This
# state can be ignored for day-to-day development on gRPC.
ignore = dirty

在grpc目录下,在git 上使用更新命令
cd grpc
git submodule update --init
使用cmake对grpc进行编译。
编译结束后,使用vs打开目录中的grpc.sln文件
右键ALL——BUILD,点击重新生成。
新建一个C++控制台项目,新建 demo.proto 文件
文件内容:
syntax = "proto3";
package hello;
service Greeter {
rpc SayHello (HelloRequest) returns (HelloReply) {}
}
message HelloRequest {
string message = 1;
}
message HelloReply {
string message = 1;
}
在资源文件中右键添加现有项,将demo.proto 文件添加进来。
demo.proto里面不能有中文或者utf-8的格式
在自己新建的控制台项目中,按住Shift + 右键 调处控制台
接下来我们利用grpc编译后生成的proc.exe生成proto的头文件和源文件
D:\cpp_grpc\visualpro\third_party\protobuf\Debug\protoc.exe -I="." --grpc_out="." --plugin=protoc-gen-grpc="D:\cpp_grpc\visualpro\Debug\grpc_cpp_plugin.exe" "demo.proto"
D:\cpp_grpc\visualpro\third_party\protobuf\Debug\protoc.exe --cpp_out=. "demo.proto"
生成出来的文件:
将这4个都右键添加现有项的方法添加到C++的控制台项目中去。
开始配置VS
右键项目,点击属性,选择c/c++,选择常规,选择附加包含目录
D:\cpp_grpc\grpc\third_party\re2
D:\cpp_grpc\grpc\third_party\address_sorting\include
D:\cpp_grpc\grpc\third_party\abseil-cpp
D:\cpp_grpc\grpc\third_party\protobuf\src
D:\cpp_grpc\grpc\include
接下来配置库路径, 在链接器常规选项下,点击附加库目录,添加我们需要的库目录。
右键项目,点击属性,选择链接器,选择附加库目录
D:\cpp_grpc\visualpro\third_party\re2\Debug
D:\cpp_grpc\visualpro\third_party\abseil-cpp\absl\types\Debug

另外,我们虽然配置了库目录,但还要将要使用的库链接到项目
点击链接器,选择输入选项,点击附加依赖项,添加依赖的库名字

编写服务端代码:
#include
#include
#include
#include
#include "demo.grpc.pb.h"
using grpc::Server;
using grpc::ServerBuilder;
using grpc::ServerContext;
using grpc::Status;
using hello::HelloRequest;
using hello::HelloReply;
using hello::Greeter;
// Logic and data behind the server's behavior.
class GreeterServiceImpl final : public Greeter::Service {
Status SayHello(ServerContext* context, const HelloRequest* request,
HelloReply* reply) override {
std::string prefix("llfc grpc server has received : ");
reply->set_message(prefix + request->message());
return Status::OK;
}
};
void RunServer() {
std::string server_address("127.0.0.1:50051");
GreeterServiceImpl service;
ServerBuilder builder;
// Listen on the given address without any authentication mechanism.
// 监听给定的地址
builder.AddListeningPort(server_address, grpc::InsecureServerCredentials());
// Register "service" as the instance through which we'll communicate with
// clients. In this case it corresponds to an *synchronous* service.
builder.RegisterService(&service);
// Finally assemble the server.
std::unique_ptr<Server> server(builder.BuildAndStart());
std::cout << "Server listening on " << server_address << std::endl;
// Wait for the server to shutdown. Note that some other thread must be
// responsible for shutting down the server for this call to ever return.
server->Wait();
}
int main(int argc, char** argv) {
RunServer();
return 0;
}
写完使用x64平台运行一下。
右键添加新建项目,grpcclient客户端
为了不重新配置一边,找到当前路径
直接复制过去,就完成了配置。
还要复制以下这4个文件到客户端,再使用右键添加现有项,将这4个添加进去。
客户端代码:
#include
#include
#include
#include
#include "demo.grpc.pb.h"
using grpc::ClientContext;
using grpc::Channel;
using grpc::Status;
using hello::HelloReply;
using hello::HelloRequest;
using hello::Greeter;
// static method : Greeter::NewStub
class FCClient {
public:
FCClient(std::shared_ptr<Channel> channel)
:stub_(Greeter::NewStub(channel)) {
}
std::string SayHello(std::string name) {
ClientContext context;
HelloReply reply;
HelloRequest request;
request.set_message(name);
Status status = stub_->SayHello(&context, request, &reply);
if (status.ok()) {
return reply.message();
}
else {
return "failure " + status.error_message();
}
}
private:
std::unique_ptr<Greeter::Stub> stub_;
};
int main(int argc, char* argv[]) {
auto channel = grpc::CreateChannel("127.0.0.1:50051", grpc::InsecureChannelCredentials());
FCClient client(channel);
// block until get result from RPC server
std::string result = client.SayHello("hello , llfc.club !");
printf("get result [%s]\n", result.c_str());
return 0;
}
运行效果:
