Should I add some plugin, or some option into protoc, or call something special instead SerializeTo/ParseFrom? Is it someone who use that feature? 回答1: I'm using Protobuf 3.3.0, which does have a built-in JSON serializer and parser. You can use 2 functions from google/protobuf/util/json_util.h called MessageToJsonString() and JsonStringToMessage() to make your C++

On Linux the Protobuf library is found by: find_package( Protobuf REQUIRED ) CMake knows where to look for the library. How though do I get this to work in Windows? Is there an environment variable I should create, such as PROTOBUF_LIB ? I have looked in FindProtobuf.cmake but cannot work out what is required. 回答1: I also struggled with this. To be more clear. On Windows (7, similar on older windows): Start --> Control Panel --> System --> Advanced System Settings --> Environment Variables Then either

I am on Win64 and have MinGW with installed the mingw-developer-toolkit , mingw32-base , mingw-gcc-g++ , msys-base and additionally mingw32-phtreads-w32 . Under MinGW/msys/1.0 I create the folder /home/<username> and paste the protobuf-3.1.0 source downloaded from github . I open an MSYS shell, cd into the protobuf dir and run ./autoconfig : the log is here . Now, the first thing I don't like

前两天想在微博上发表一个观点：在现在的技术体系中，能用于描述通讯协议的方式很多，xml,json,protobuf，thrift，如果在有如此众多选择的基础上，在设计系统时，还自造协议，自己设计协议类型和解析方式，那么我只能说，您真的落后了，不是技术上，而是思想上。对于xml,和json我们不做过多描述了，参考相关文档就可以了。特别是json，如今在 web系统，页游系统的前后台通讯中，应用非常广泛。 本文将重点介绍两种目前在大型系统中，应用比较普遍的两种通讯框架，thrift和Protobuf ，为什么叫通讯框架，而不叫通讯协议？因为这两种技术，如果仅仅当作协议解析用，对于其强大的功能，就大打了折扣。 对于 两种利器而言，首推的应该是thrift ，因为其不仅有对于协议封装和解析的处理，而且有完备的通讯框架的实现，完全封装了底层通讯 ，对于使用者，只要在框架的客户端和服务器接口回调中，处理逻辑就可以了 。对于其确切的描述，我们还是引用官方的说法吧，这样更准确些，以免由于我自己的想法，影响了大家的理解。 Thrift是一个跨语言的服务部署框架，最初由Facebook于2007年开发，2008年进入Apache开源项目。Thrift通过一个中间语言(IDL, 接口定义语言)来定义RPC的接口和数据类型，然后通过一个编译器生成不同语言的代码（目前支持C++,Java, Python,
