google protobuf 各个语言的使用

protobuf

https://github.com/google/protobuf

generate

protoc --cpp_out=D:/Workspace/visualstudio/protobuf/protobuf typhoon.proto
protoc -I=. --go_out=D:/Workspace/golang/src/webservice/lib/typhoon typhoon.proto

::--js_out: The add_require_for_enums, testonly, library, error_on_name_conflict, extension, and one_output_file_per_input_file options should only be used for import_style=closure

pause

golang

c/c++

使用nmake编译源码

Any类型的用法

python

javascript

注意：javascript必须设置每一个字段的值，否则会和其他语言无法正常解析，因为javascript会少字段

Closure Imports

protoc --js_out=library=myproto_libs,binary:. messages.proto base.proto

CommonJS imports

protoc --js_out=import_style=commonjs,binary:. messages.proto base.proto

安装 google-protobuf

npm install google-protobuf

demo

var typhoon = require("./typhoon_pb.js");
