Question

我想将我的Rapsberry配置为SMS Ping Pong播放器。所以我安装了gammu-smsd并按如下方式配置了gammu-smsdrc：

# Configuration file for Gammu SMS Daemon

# Gammu library configuration, see gammurc(5)
[gammu]
# Please configure this!
port = /dev/ttyUSB3
pin= 4135
connection = at
# Debugging
logformat = textall

# SMSD configuration, see gammu-smsdrc(5)
[smsd]
RunOnReceive = sudo /var/spool/gammu/receivesms.sh
service = files
pin = 4135
# Increase for debugging information
debuglevel = 1
logfile = /var/spool/gammu/gammu.log
include_smsc = 491722270333

# Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/

到目前为止，发送短信接收短信工作正常！

所以我尝试了那个无法接受的事情。并写了一个小脚本，应该获取短信发送者号码和文本。如果文本是“ping”，gammu-smsd应该将pong发送给发件人。

reveivessms.sh：

#!/bin/sh
from=$SMS_1_NUMBER
message=$SMS_1_TEXT
reply=""

if test "$message" = "Ping"; then
    reply="Pong!"
else
    reply="Y U NO PLAY PING PONG?"
fi


sudo echo "$reply" | /usr/bin/gammu-smsd-inject -c /etc/gammu-smsdrc TEXT "$from"

gammu.log是：

嗯没有留言回复......

所以我尝试了不传递参数并将receivems.sh更改为：

#!/bin/sh
sudo echo Gude Wie | /usr/bin/gammu-smsd-inject -c /etc/gammu-smsdrc TEXT 49160xxxx

一切正常。似乎，传递给receicesms.sh的变量不起作用。但我不明白为什么？

Answer 1

通过gammu-smsd-inject获取发送短信的接收是一项任务。

对于遇到此问题的其他人。我通过将gammu-smsd-inject命令的stdout和stderr重定向到/ dev / null来解决它。

echo "This somehow works" | gammu-smsd-inject TEXT $from > /dev/null 2>&1

此致

Answer 2

问题是sudo没有将环境变量保留在默认配置中，所以我建议你不要在脚本中使用sudo。以root身份运行SMSD也是潜在的安全风险，因为在SMS解码中出现一些错误时，攻击者直接以root身份运行。

因此，以用户身份运行SMSD并更改/ var / spool / gammu和调制解调器/电话设备的权限会更好。

如果您坚持以root身份运行SMSD，请更改sudo配置以保留环境变量，请参阅How to keep Environment Variables when Using SUDO

Gammu runonreceive没有传递变量
