从telnet向Beanstalkd发送命令时出错

Question

[当我通过telnet发送以下序列时，我得到EXPECTED_CRLF：

$ telnet localhost 11300
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
put 0 0 1 4 
68 6f 6c 61
EXPECTED_CRLF
UNKNOWN_COMMAND

我以为，当我在telnet中按“ Enter”时，它将发送一个“ CR LF”（https://www.freesoft.org/CIE/RFC/1123/31.htm）

此处是Beantalkd协议：https://github.com/beanstalkd/beanstalkd/blob/master/doc/protocol.txt

我尝试像@Alister Bulman所说的那样切换crlf，但是它没有用：

$ telnet
telnet> toggle crlf
Will send carriage returns as telnet <CR><LF>.
telnet> open localhost 11300
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
put 0 0 1 4
68 6f 6c 61
EXPECTED_CRLF
UNKNOWN_COMMAND

Answer 1

这里的问题是：您可以发送文本而无需将其编码为字节。对于文本“ hola”而言，正确的是4个字节，但是对于“ 68 6f 6c 61”而言，其长度必须为“ 11”个字节。我误解了该协议，因为它被描述为<data>的“字节序列”。实际上，TCP传递是字节流！

- <data> is the job body -- a sequence of bytes of length <bytes> from the previous line.

所以正确的命令是：

$ telnet
telnet> open localhost 11300
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
put 0 0 1 4
hola
INSERTED 1
put 0 0 1 11
68 6f 6c 61
INSERTED 2
