Golang将SQL多行查询结果写入Map

var list []map[string]interface{}

for rows.Next() {

	// 构造缓冲并接收

	buffer := make([]interface{}, len(columns))

	for key := range buffer {

		buffer[key] = &buffer[key]

	}

	rows.Scan(buffer...)

	// 将缓冲映射到行Map

	row := make(map[string]interface{})

	for key, val := range columns {

		row[val] = buffer[key]

	}

	// 加入帖子列表

	list = append(list, row)

}
