1. 链接
https://github.com/google/protobuf
下载下面的3个压缩包。
protobuf-cpp-3.4.0.tar.gz
protobuf-cpp-3.4.0.zip
protoc-3.4.0-win32.zip
protobuf-cpp-3.4.0.tar.gz 和 protobuf-cpp-3.4.0.zip 是一样的，都是源代码。
protoc-3.4.0-win32.zip 是一个自动生成代码的工具。
2.编译库
将 protobuf-cpp-3.4.0.zip 解压
在 protobuf-3.2.0\cmake 目录下创建子目录 build/solution
进入目录 protobuf-3.2.0\cmake\build\solution,
执行命令 cmake -G “Visual Studio 14 2015” ../..
下面这是一些其他的Visual Studio版本：
Visual Studio 15 2017 [arch] = Generates Visual Studio 2017 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 14 2015 [arch] = Generates Visual Studio 2015 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 12 2013 [arch] = Generates Visual Studio 2013 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 11 2012 [arch] = Generates Visual Studio 2012 project files.
Optional [arch] can be "Win64" or "ARM".
Visual Studio 10 2010 [arch] = Generates Visual Studio 2010 project files.
Optional [arch] can be "Win64" or "IA64".
Visual Studio 9 2008 [arch] = Generates Visual Studio 2008 project files.
Optional [arch] can be "Win64" or "IA64".
Visual Studio 8 2005 [arch] = Generates Visual Studio 2005 project files.
Optional [arch] can be "Win64".
Visual Studio 7 .NET 2003 = Deprecated. Generates Visual Studio .NET
然后就会在 solution 目录下生成 Visual Studio 的工程。
3. 使用
新建Message.proto文件
syntax = "proto2";
package tutorial;
message Person {
optional string name = 1;
optional int32 id = 2;
optional string email = 3;
enum PhoneType {
MOBILE = 0;
HOME = 1;
WORK = 2;
}
message PhoneNumber {
optional string number = 1;
optional PhoneType type = 2 [default = HOME];
}
repeated PhoneNumber phone = 4;
}
message AddressBook {
repeated Person person = 1;
}
执行命令：
protoc -I=./ --cpp_out=./ Message.proto
然后会自动生成 Message.pb.h 和 Message.pb.cc 这两个文件。
这是测试文件：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <iostream>
#include <string>
#include "Message.pb.h"
using namespace std;
int main()
{
printf("ProtoBuf Demo\n");
GOOGLE_PROTOBUF_VERIFY_VERSION;
tutorial::AddressBook oAddressBook;
printf("oAddressBook.person_size() = %d\n", oAddressBook.person_size());
::tutorial::Person* poPerson = oAddressBook.add_person();
poPerson->set_id(1);
poPerson->set_name("Person 1");
poPerson->set_email("person1@qq.com");
::tutorial::Person_PhoneNumber* poPhoneNumberHome = poPerson->add_phone();
poPhoneNumberHome->set_number("12345678");
poPhoneNumberHome->set_type(::tutorial::Person::HOME);
poPhoneNumberHome->set_type(::tutorial::Person_PhoneType_HOME);
::tutorial::Person_PhoneNumber* poPhoneNumberWork = poPerson->add_phone();
poPhoneNumberWork->set_number("87654321");
poPhoneNumberWork->set_type(::tutorial::Person::WORK);
//poPhoneNumberWork->set_type(::tutorial::Person_PhoneType_WORK);
printf("poPerson->phone_size() = %d\n", poPerson->phone_size());
printf("oAddressBook.person_size() = %d\n", oAddressBook.person_size());
string strOutput;
oAddressBook.SerializePartialToString(&strOutput);
printf("strOutput: [%s]\n", strOutput.c_str());
tutorial::AddressBook oAddressBookOutput;
oAddressBookOutput.ParseFromString(strOutput);
printf("oAddressBookOutput.person_size() = %d\n", oAddressBookOutput.person_size());
google::protobuf::ShutdownProtobufLibrary();
return 0;
}
