这一行负责解析为int32

dubbo-go-hessian2/decode.go

Line 273 in c18594c

case (0x80 <= tag && tag <= 0xbf) || (0xc0 <= tag && tag <= 0xcf) ||

位置位于解析byte之前：

dubbo-go-hessian2/decode.go

Line 295 in c18594c

case (tag == BC_BINARY) || (tag == BC_BINARY_CHUNK) || (tag >= 0x20 && tag <= 0x2f) ||

而'B' byte 标会优先进入int32的处理分支，被解析为int32，因为'B' == 0x91 ，符合int32的第一个条件。
