SMS with two factor authentification

[oley]

Hi,

I need to send an SMS about a discreet channel change.
I have modems that can send SMS messages, but they work with double authorization: first, a request for a token with access data, and then sending an SMS with the token.
An example PS script looks like this:

$ip = "172.16.1.2:81"
$username = "admin"
$password = "pass"
$phoneNumber = "+48123456789"
$messageText = "Test sms"
$modemId = "2-1"

try {
    $loginUrl = "http://$ip/api/login"
    $loginBody = @{ username = $username; password = $password } | ConvertTo-Json

    $loginResponse = Invoke-RestMethod -Uri $loginUrl -Method Post -Body $loginBody -ContentType "application/json"
    $token = $loginResponse.token
} catch {
    exit 1
}

try {
    $smsUrl = "http://$ip/api/messages/actions/send"
    $smsBody = @{ data = @{ number = $phoneNumber; message = $messageText; modem = $modemId } } | ConvertTo-Json -Depth 3

    $smsResponse = Invoke-RestMethod -Uri $smsUrl -Method Post -Body $smsBody -ContentType "application/json" -Headers @{ Authorization = "Bearer $token" }
} catch {
    exit 1
}

I don’t really see the possibility of standard notification from Rapid SCADA.
I could write this code in C# and use it to send SMS messages.

Please give me some tips on how to approach this.

Best regards
Przemek

Hi,

Check DrvHttpNotif driver. It can send HTTP requests according to commands.
To send a sequence of commands, use Auto Control Module.
Ask for additional info if needed.

[Mikhail]

Probably, the existing driver does not preserve a token returned by the 1st request.

[Mikhail]

Is it possible for you to select an alternative service that needs only one HTTP request to send a message?

[oley]

Thank you,
yes I will provide simple proxy service which can become single request and make two-factor request.

[oley]

Is there a possibility to simply test if this solution works?
If I had the service which works like:

Invoke-RestMethod -Uri "http://localhost:5150/send-sms" -Method Post -Headers @{ "Content-Type" = "application/json" } -Body '{"phoneNumber":"+48111111111","message":"Test API"}'

and put Url into DrvHttpNotif with content type json and so on. How to send a test message?

[oley]

<?xml version="1.0" encoding="utf-8"?>
<NotifDeviceConfig>
  <Uri>http://localhost:5150/send-sms</Uri>
  <Method>Post</Method>
  <Headers>
    <Header name="Content-Type" value="application/json" />
  </Headers>
  <Content>{
  "phoneNumber": "+486011111",
  "message": "SCADA"
}
</Content>
  <ContentType>application/json</ContentType>
  <ContentEscaping>EncodeJson</ContentEscaping>
  <ParamEnabled>false</ParamEnabled>
  <ParamBegin>[</ParamBegin>
  <ParamEnd>]</ParamEnd>
  <AddrSep>;</AddrSep>
</NotifDeviceConfig>

One more request: could you remove the phone number from the configuration I sent? I can’t edit my message.

[oley]

I made it work.
I created a proxy service that accepts POST requests and sends SMS messages with two-factor authentication based on them.
Since the request is in JSON format, I have to use [param] instead of {param} for the parameters.
The Headers tab probably refers to the response, because when I set Content-Type there, I kept getting the error: “Error creating request: Misused header name, ‘Content-Type’. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.”

I will send something like: {CnlName} on {EvDev} at {EvObj} changed value to {CnlVal}

I suppose this should be Channel Data Change Trigger and than Command with code “Request” to my Notifier device.
Now is the question: how to send SMS to a recipient from the address book?

[Mikhail]

I’ve checked the source code of the driver.
Parameters (phone number and text) can be inserted in the request URL and content.
This is so weird that the service requires to insert phone number in the request header. Usually headers contain auth tokens and similar things.
P.S. Phone number in the above was changed.

You wrote
-Body '{"phoneNumber":"+48111111111","message":"Test API"}'
It’s related to the request contents, not headers.

[Mikhail]

Example of the content:

{
    "from": "SCADA",
    "to": [phone], 
    "message": "[text]" 
}

Set ParamEnabled to true.

[Mikhail]

To use a phone book, see the available commands in the driver description on the Drivers page.

Hi Mikhail,

thank you. I can send an SMS from SCADA with simple “Request” command. It works.
Now I want to use it as notifier. So I have some contacts in the address book.
I have Channel Data Change Trigger in ACM.
How to connect this together? Command to device DrvHttpNotif? But how to access this address book?

[oley]

Can’t find any doc for this driver. Can you give me a link to this description?
