Question

我想在Asterisk中转义\到\\和“到\”。我试过使用REPLACE但是我无法让它工作。我目前的方法如下

exten => sms,1,Set(UNSAFESMSTXT=${REPLACE(SMSTXT,\\,\\\\)})
exten => sms,2,Set(SAFESMSTXT=${REPLACE(UNSAFESMSTXT,",\\")})
; Echo escaped input to terminal safely
exten => sms,n,System(echo "${SAFESMSTXT}")

当我发送echo hi“echo hi时，我收到错误

ERROR[8239]: func_strings.c:804 replace: The characters to search for and the variable name must not be empty.

如果有帮助，我会使用chan_mobile。

功能描述中不清楚的是什么？

Asterisk func REPLACE
Synopsis:
Replace a set of characters in a given string with another character.

Description:
Iterates through a string replacing all the <find-chars> with <replace-ch
ar>. <replace-char> may be either empty or contain one character. If empty,
all <find-chars> will be deleted from the output.
NOTE: The replacement only occurs in the output. The original variable is
not altered.

Syntax:
REPLACE(varname,find-chars[,replace-char])

你有使用\＆＃34;而不是＆＃34;
