三、使用Java源码过程中报错

1. 解析时报错：Protocol message tag had invalid wire type 异常 
   原因：二进制的内容不能直接在http协议传输，传输的内容可能有压缩或者base64编码，需要对接收到的二进制数据做解压缩或者base64解码。
2. 解析式报错：Protocol message contained an invalid tag (zero) 
   原因：待解析的二进制数据中不全是pb二进制数据，可能还有其它内容，例如二进制数据头部约定的错误信息长度、错误信息字符串内容等。

 

原因：字段变动

少字段，或者字段顺序发生变化，（并且该字段有值）则会报此异常！

fieldNumber每个字段的标号，wire_type是该字段的数据类型，所有如果我们改变了业务对象类中字段的顺序，或者改变了字段的类型，都会出现反序列化失败；
