New plugin HttpImport could be interesting

[popaserge]

I am not able to code by myself a new plugin but I saw that MqttImport is able to parse a Json string.
I think that for specialists it could be very easy to use the parsing possibilities allready used in MgttImport and apply them in a new plugin using the SendToHttp command feature.
I have a device used before I happened to know EspEasy which is able to answer to a http request by a Json string after easy configuration in it of a cgi file and made a trial.
Answer in a browser : { PuissancePAC :620, IntensitePAC :3, Nappe_Arr :14.06, Exterieur :10.06, PAC_Retour :37.25, PACext_Ret :14.56, Interieur :19.31, PAC_Sortie :37.56, Nappe_Ret :13.25, PACext_Sor :14.75, Air_Pulse :33.75 }

In the tools/command of Espeasy I sent a SendToHttp command to this device and looked to the reaction in the log.
It seems that the data are well received; here is the log data and the way for such a new plugin is maybe not so far

+1 on this, fetch a target URL and parse the JSON response, that's it. No need to interfere with SendToHTTP

I'm currently using a ESP8266 with a relay shield connected to a 12v car horn as an alarm that reads the status of a webcam and sounds the horn if the camera is in an alarm state because of visual movement.
It would be awesome if this could be done with rules.

Current code (partial):

    const String cam_PortariaEsq = "http://192.168.8.221:28021/get_status.cgi?user=myUser&pwd=myPwd";
    HTTPClient http;
    http.begin(wifiClient, cam_PortariaEsq);
    int httpCode = http.GET();
    // httpCode will be negative on error
    if (httpCode > 0) {
      if (httpCode == HTTP_CODE_OK) {
        //HTTP_CODE_OK means code == 200
        String payload = http.getString();     
        int tempindex = payload.indexOf("var alarm_status=1");
        if (tempindex > 0) {
          RelayAlarm(0.5, 0.5, 3);
          delay(30000); // Insures no more beeps until 30s passed
        }
      }
