"Content String Enrichment" in "Network Request" question

[kurogedelic]

Hello.
I want to use the Network Request for my PHP, but I am having trouble with the expansion of #HAA@aacc'. I am writing it in the URL, not in the content.
My PHP that logs temperature and humidity sensor data sent via URL GET queries.
The following cURL command succeeds in doing so.
So, is it possible that the expansion of #HAA@aacc is only happening within the 'contents'?

cURL command (success) :
http://host.com/data.php?write=true&key=xxxxxtemp2=25.0&hum2=99

MEPLHAA Script (Nothing happens):

.....
"a": [
        {
            "t": 24,
            "n": 2,
            "g": 4,
            "k": 10,
            "j": 30,
            "y0": [
                {
                    "v": 0,
                    "r": 1,
                    "0": {
                        "h": [
                            {
                              "h": "host.com",
                              "u": "data.php?write=true&key=xxxxx&temp2=#HAA@0000&hum2=#HAA@0001"
                            }
                          ]
                    }
                }
            ]
        },
        .....
 ]

Thanks!

This is not documented, but there are 2 major issues in HAA:

1. you must use POST method to send parameter
2. you must send specific header
   Here's the example which works for me:

        "h": [{
          "h": "192.168.1.1",
          "m": 2,
          "e": "Content-type: application/x-www-form-urlencoded\r\n",
          "u": "write_data.php",
          "c": "t1=#HAA@0100&t2=#HAA@0200&t3=#HAA@0300"
          }] 

hope that helps

I tried changing it like that, but it doesn't seem to work.

         "h": [
                            {
                              "h": "host.com",
                              "m": 2,
                              "e": "Content-type: application/x-www-form-urlencoded\r\n",
                              "u": "data.php",
                              "c": "write=true&key=xxxx&temp2=#HAA@0100&hum2=#HAA@0200"
                            }
                          ]

However, using the code I posted at the very beginning,
If #HAA@aabb is not used, the data is sent to PHP.
So I think #HAA@aabb is not converted to a string well.
What does aabb refer to?

Thanks.

If the string contains the magic expression #HAA@aacc then the expression will be replaced by the characteristic cc value from the service aa e.g. #HAA@0100 will be replaced with the value held by characteristic 0 from service 1.

debug the log with "o":4 option in config, it should help

If connect with serial and look at the serial port,Found this:
! <1> TCP (-3)

I set it to "m":2 and also changed PHP to receive POST.
This is an error, isn't it?
