win10系统 C++环境安装编译GRPC

第一步下载源码、更新、cmake编译：

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
在这里插入图片描述

复制下面内容替换.gitmodules内容：

[submodule "third_party/zlib"]path = third_party/zlib#url = https://github.com/madler/zliburl = 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
[submodule "third_party/protobuf"]path = third_party/protobuf#url = https://github.com/google/protobuf.giturl = https://gitee.com/local-grpc/protobuf.git
[submodule "third_party/googletest"]path = third_party/googletest#url = https://github.com/google/googletest.giturl = https://gitee.com/local-grpc/googletest.git
[submodule "third_party/benchmark"]path = third_party/benchmark#url = https://github.com/google/benchmarkurl = https://gitee.com/mirrors/google-benchmark.git
[submodule "third_party/boringssl-with-bazel"]path = third_party/boringssl-with-bazel#url = https://github.com/google/boringssl.giturl = https://gitee.com/mirrors/boringssl.git
[submodule "third_party/re2"]path = third_party/re2#url = https://github.com/google/re2.giturl = https://gitee.com/local-grpc/re2.git
[submodule "third_party/cares/cares"]path = third_party/cares/cares#url = https://github.com/c-ares/c-ares.giturl = https://gitee.com/mirrors/c-ares.gitbranch = cares-1_12_0
[submodule "third_party/bloaty"]path = third_party/bloaty#url = https://github.com/google/bloaty.giturl = https://gitee.com/local-grpc/bloaty.git
[submodule "third_party/abseil-cpp"]path = third_party/abseil-cpp#url = https://github.com/abseil/abseil-cpp.giturl = https://gitee.com/mirrors/abseil-cpp.gitbranch = lts_2020_02_25
[submodule "third_party/envoy-api"]path = third_party/envoy-api#url = https://github.com/envoyproxy/data-plane-api.giturl = https://gitee.com/local-grpc/data-plane-api.git
[submodule "third_party/googleapis"]path = third_party/googleapis#url = https://github.com/googleapis/googleapis.giturl = https://gitee.com/mirrors/googleapis.git
[submodule "third_party/protoc-gen-validate"]path = third_party/protoc-gen-validate#url = https://github.com/envoyproxy/protoc-gen-validate.giturl = https://gitee.com/local-grpc/protoc-gen-validate.git
[submodule "third_party/udpa"]path = third_party/udpa#url = https://github.com/cncf/udpa.giturl = https://gitee.com/local-grpc/udpa.git
[submodule "third_party/libuv"]path = third_party/libuv#url = https://github.com/libuv/libuv.giturl = https://gitee.com/mirrors/libuv.git

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。
在这里插入图片描述

编译结束后，使用vs打开目录中的grpc.sln文件
在这里插入图片描述
右键ALL——BUILD，点击重新生成。

第二步编写 .proto 文件

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

第三步生成头文件与源文件

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"

在这里插入图片描述
生成出来的文件：

第四步配置VS

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

在这里插入图片描述

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
D:\cpp_grpc\visualpro\third_party\abseil-cpp\absl\synchronization\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

第五步编写服务端代码：

编写服务端代码：

#include <iostream>
#include <memory>
#include <string>
#include <grpcpp/grpcpp.h>
#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。

第六步编写客户端代码：

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
在这里插入图片描述

在这里插入图片描述
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 <string>
#include <iostream>
#include <memory>
#include <grpcpp/grpcpp.h>
#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 serverstd::string result = client.SayHello("hello , llfc.club !");printf("get result [%s]\n", result.c_str());return 0;
}
