json2pb

json2pb

Json2pb是一个可以把json对象转换为Protobuf编码的命令行工具。

• 修复protobufjs整数溢出不报错的问题
• 忽略protobufjs对于optional字段不存在依然报错的问题。
• 增加makefile依赖文件输出的功能。
• Node.js 不支持64位整数的问题依旧木有解决~~

把Json对象用Protobuf打包只需要输入：json2pb -pmotion.proto -mmotion motion.json

想要把csv文件打包的朋友们， 可以先用evalcsv把csv文件转换为json对象。

Install

1. Install node.js

2. Install with npm

    npm install -g json2pb

Example

motion.json:

	{
	      "rows": [
	          {
	              "motion_id": 11001,
	              "name": "跪姿肩部下沉",
	              "privileges": [
	                  "owner",
	                  "admin",
	                  "user",
	                  "guest"
	              ],

	              "category": "胸",
	          },
	          {
	              "motion_id": 11002,
	              "name": "直体肩部下沉",
	              "privileges": [
	                  "owner",
	                  "admin",
	                  "user",
	                  "guest"
	              ],
	              "type": "热身",
	              "category": "胸",
	          }
	      ]
	    }

motion.proto:

	syntax = "proto3";
		message motion_row {
        	int32 motion_id = 1;
         	string name = 2;
  		repeated string privileges = 3;
        	string type = 4;
         	string category = 5;
		}

		message motion {
			repeated motion_row rows = 1;
		}

command line:

	json2pb -pmotion.proto -mmotion motion.json
