通过 Netcat 向 Memcached 发送 UDP 数据包

我正在尝试stats通过 netcat 将命令发送到 memcached，但是，我没有从 memcached 得到任何返回...

我努力了

echo "stats" > commands.txt
nc -u 127.0.0.1 11211 < commands.txt

我也试过

echo stats | nc -u 127.0.0.1 11211

根据我在Memcached 文档底部的第1176 行阅读的内容，发送时的命令可能必须包括

Each UDP datagram contains a simple frame header, followed by data in the
same format as the TCP protocol described above. In the current
implementation, requests must be contained in a single UDP datagram, but
responses may span several datagrams. (The only common requests that would
span multiple datagrams are huge multi-key "get" requests and "set"
requests, both of which are more suitable to TCP transport for reliability
reasons anyway.)

The frame header is 8 bytes long, as follows (all values are 16-bit integers 
in network byte order, high byte first):

0-1 Request ID
2-3 Sequence number
4-5 Total number of datagrams in this message
6-7 Reserved for future use; must be 0

我的问题是，如何stats使用 netcat 通过 udp 将命令发送到 Memcached？
