string map with variables including quotes

I'm trying to do some irule manipulation of JSON payload data and in specific cases add a couple of fields to the payload. At this point, I'm simply logging my changes but once I validate that this ...

Look at this in tclsh (shell available on most of linux OS and also on bigip)

 

Your command :

 

 

$ tclsh
% set payload "\{\"parameter1\":\"value1\",\"Phone\":\"7345551212\",\"parameter2\":\"value2\"\}"
{"parameter1":"value1","Phone":"7345551212","parameter2":"value2"}
% set searchvalue "\"Phone\":\"7345551212\","
"Phone":"7345551212",
% set replacevalue "\"Phone\":\"7345551212\",\"TestData\":\"Yes\","
"Phone":"7345551212","TestData":"Yes",
% string map "${searchvalue} ${replacevalue}" ${payload}
list element in quotes followed by ":"7345551212"," instead of space

 

with search / replace strings between curly brackets:

 

 

$ tclsh
% set payload "\{\"parameter1\":\"value1\",\"Phone\":\"7345551212\",\"parameter2\":\"value2\"\}"
{"parameter1":"value1","Phone":"7345551212","parameter2":"value2"}
% set searchvalue {\"Phone\":\"7345551212\",}
\"Phone\":\"7345551212\",
% set replacevalue {\"Phone\":\"7345551212\",\"TestData\":\"Yes\",}
\"Phone\":\"7345551212\",\"TestData\":\"Yes\",
% string map "${searchvalue} ${replacevalue}" ${payload}
{"parameter1":"value1","Phone":"7345551212","TestData":"Yes","parameter2":"value2"}

 

or with string map list created before (with curly brackets)

 

 

$ tclsh
% set payload "\{\"parameter1\":\"value1\",\"Phone\":\"7345551212\",\"parameter2\":\"value2\"\}"
{"parameter1":"value1","Phone":"7345551212","parameter2":"value2"}
% set stringmap {"\"Phone\":\"7345551212\"," "\"Phone\":\"7345551212\",\"TestData\":\"Yes\","}
"\"Phone\":\"7345551212\"," "\"Phone\":\"7345551212\",\"TestData\":\"Yes\","
% string map $stringmap ${payload}
{"parameter1":"value1","Phone":"7345551212","TestData":"Yes","parameter2":"value2"}

 

or with string map list created before (with list command)

 

 

$ tclsh
% set payload "\{\"parameter1\":\"value1\",\"Phone\":\"7345551212\",\"parameter2\":\"value2\"\}"
{"parameter1":"value1","Phone":"7345551212","parameter2":"value2"}
set stringmap [list "\"Phone\":\"7345551212\"," "\"Phone\":\"7345551212\",\"TestData\":\"Yes\","]
{"Phone":"7345551212",} {"Phone":"7345551212","TestData":"Yes",}
% string map $stringmap ${payload}
{"parameter1":"value1","Phone":"7345551212","TestData":"Yes","parameter2":"value2"}
%

 

or with string map list created before (from searchvalue variable)

 

 

$ tclsh
% set payload "\{\"parameter1\":\"value1\",\"Phone\":\"7345551212\",\"parameter2\":\"value2\"\}"
{"parameter1":"value1","Phone":"7345551212","parameter2":"value2"}
% set searchvalue "\"Phone\":\"7345551212\","
"Phone":"7345551212",
% set stringmap [list $searchvalue $searchvalue"\"Phone\":\"7345551212\",\"TestData\":\"Yes\","]
{"Phone":"7345551212",} {"Phone":"7345551212",""Phone":"7345551212","TestData":"Yes","}
% string map $stringmap ${payload}
{"parameter1":"value1","Phone":"7345551212",""Phone":"7345551212","TestData":"Yes",""parameter2":"value2"}
