msgpack代替json防止丢失类型

妙音 posted @ 2021年6月30日 15:12 in golang , 1786 阅读
 

描述

 
开发了一个通信协议, 协议对数据类型比较敏感, 根据不同数据数据类型使用不同格式。golang的数据类型能够满足需求。
 
然而,将协议转为http方式时,如果传入json,会发现数据类型不符合预期
 
例如,本来是应该int结果是float64; 本来应该是[]byte,结果是string
 

环境

 
http服务器: gin
 
开发语言: golang
 

解决方法探寻

 
什么传输协议会带上数据类型?
 
* json类型丢失
 
默认情况下gin的BindJSON,可将传入的参数绑定到具体的结构体,产生类型转换。然后,我的结果需要是动态的,不知道参数的具体内容。
 
* 自定义参数格式,将类型带上。例如 marchinery
 
Arg struct{
    Type string
    Value interface{}
}
 
缺点:太麻烦
 
* 常用协议中选择
 
xml         可以用,不理想
 
yaml        不能解决问题
 
protobuf    不能解决问题
 
messagepack 有详细的数据类型,完美
 
 

msgpack替代json

 
gin示例
 
func SendXX(c *gin.Context){
    rawData, _ := c.GetRawData()
    var param interface{}
    msgpack.Unmarshal(rawData, ¶m)

result := struct{
Name string
}{
Name: "xxx",
}
resultData, _ := msgpack.Marshal(result)
c.Data(200, "application/x-msgpack", resultData)
}
 

备注

 
* gin自带的msgpack版本是1.1.7不好用,不会自动进行类型转换。 最好改用  github.com/vmihailenco/msgpack/v5
 
* 替换gin中的部分接口就可以,不用全部改为msgpack
