你的问题非常不具体，你没有展示你已经做了什么。
由于我不知道你实际的问题所在，我将只是发布我之前在使用gocql包测试cassandra时编写的WriteRecord函数：
func (cs *cassandra) WriteRecord(table string, fields []string, values ...interface{}) error {
var placeholder []string
for range fields {
placeholder = append(placeholder, "?")
}
querystring := fmt.Sprintf(insertstring, table, strings.Join(fields, ", "), strings.Join(placeholder, ", "))
return cassandraSession.Query(querystring, values...).Exec()
}
如你所见，values 的类型是 interface{}。因此，它们可以是任何类型，包括 []byte 类型。请注意，必须满足以下条件：len(fields) = len(values)。
希望这对你成为 golang 专家的旅程有所帮助

Your question is very unspecific and you do not show us what you have done so far.
Since I don't know where your actual problem lies I will just post my WriteRecord function I wrote a while back when testing cassandra with the gocql package:
func (cs *cassandra) WriteRecord(table string, fields []string, values ...interface{}) error {
var placeholder []string
for range fields {
placeholder = append(placeholder, "?")
}
querystring := fmt.Sprintf(insertstring, table, strings.Join(fields, ", "), strings.Join(placeholder, ", "))
return cassandraSession.Query(querystring, values...).Exec()
}
As you can see the values are of type interface{}. So they can be anything including of type []byte. Note that the following condition must be met: len(fields) = len(values)
I hope this helps you on your journey of becoming a golang expert
