Rewrite JSON value.

You can do this in an irule with the STREAM profile, or collect the payload parse it and rewrite it.

The question is how much parsing of the content is required to make the insertion safe.

Please provide an example of the incoming and outgoing content.

Hi Simon,

Thanks for your kind help.

I have collected some captures to show you how is the flow:

The client request a token:

POST /xxx/v2/tokenrequest/ HTTP/1.1

The client is requesting the formservices:

POST /xxx/formservice HTTP/1.1

Content-Type: application/json; charset=utf-8

{"token":"044VZAliLSXEo2l4Xcv9DFPNLQKbX7p8E3i/Zt+ksskQ+E=MDE5MDA2MjgwOTQzNzQwNjUwMjI4NzM5OUVTU0FwcDE1OTgzNDA4NzQ3NDM=","formActions": [        {      "command": "SetControlValue",      "value": "ESS",      "controlID": "15"    },        {      "command": "SetControlValue",      "value": "Ggtest",      "controlID": "19"    },     {      "command": "SetControlValue",      "value": "90013234",      "controlID": "29"    },    {      "command": "SetControlValue",      "value": "29/08/2020",      "controlID": "21"    },    {      "command": "SetControlValue",      "value": "120000",      "controlID": "25"    },    {      "command": "SetControlValue",      "value": "55",      "controlID": "35"    },        {      "command": "SetControlValue",      "value": "03",      "controlID": "33"    },    {"command": "DoAction",      "controlID": "11"}   ],   "formName": "P59MBLVR_W59MBLVRE",   "returnControlIDs":"39|31|37"  }

The Response from the server is 444 cause i am missing the "deviceName":"ESSApp" in the body:

HTTP/1.1 444 

Date: Tue, 25 Aug 2020 07:46:27 GMT

Content-Length: 162

Content-Type: application/json; charset=UTF-8

Access-Control-Allow-Methods: GET, POST, OPTIONS

Access-Control-Allow-Origin: *

{

 "message" : "Invalid Token: Please Request a New Token",

 "exception" : "java.lang.Exception",

 "timeStamp" : "2020-08-25:10.46.27"

,"deprecated":true }

What i need is to make the F5 inserting the {"deviceName":"ESSApp"} before the   "formName": "P59MBLVR_W59MBLVRE",   "returnControlIDs":"39|31|37" in the JSON body.

Many thanks in advance for your help.

Muhannad

This should be done from f5 side to the server.
