mllp_send
- MLLP network client¶
python-hl7 features a simple network client, mllp_send
, which reads HL7
messages from a file or sys.stdin
and posts them to an MLLP server.
mllp_send
is a command-line wrapper around
hl7.client.MLLPClient
. mllp_send
is a useful tool for
testing HL7 interfaces or resending logged messages:
$ mllp_send --file sample.hl7 --port 6661 mirth.example.com
MSH|^~\&|LIS|Example|Hospital|Mirth|20111207105244||ACK^A01|A234244|P|2.3.1|
MSA|AA|234242|Message Received Successfully|
Usage¶
Usage: mllp_send [options] <server>
Options:
-h, --help show this help message and exit
--version print current version and exit
-p PORT, --port=PORT port to connect to
-f FILE, --file=FILE read from FILE instead of stdin
-q, --quiet do not print status messages to stdout
--loose allow file to be a HL7-like object (\r\n instead of
\r). Requires that messages start with "MSH|^~\&|".
Requires --file option (no stdin)
Input Format¶
By default, mllp_send
expects the FILE
or stdin input to be a properly
formatted HL7 message (carriage returns separating segments) wrapped in a MLLP
stream (<SB>message1<EB><CR><SB>message2<EB><CR>...
).
However, it is common, especially if the file has been manually edited in
certain text editors, that the ASCII control characters will be lost and the
carriage returns will be replaced with the platform’s default line endings.
In this case, mllp_send
provides the --loose
option, which attempts
to take something that “looks like HL7” and convert it into a proper HL7
message..
