Android Question [SOLVED] AWS Cognito js Pre-Script

[BillMeyer]

Hi Fellow B4X'ers

A client has request for me to use AWS Cognito. I have no idea of what or how to do it. Can someone help please ???

They have given me the following pre-script I must run then a cURL...

Here is the pre-script (how do I run/convert it to B4A so that I can use it)

var clientId = pm.environment.get("cognitoClientId");
var clientSecret = pm.environment.get("cognitoClientSecret");
var username = pm.environment.get("cognitoUserName");
var password = pm.environment.get("cognitoUserPassword");
pm.sendRequest({
           url: "https://cognito-idp.us-east-2.amazonaws.com/",
           method: 'POST',
           header: {
                    'X-Amz-Target':   'AWSCognitoIdentityProviderService.InitiateAuth',
                    'Content-Type': 'application/x-amz-json-1.1'
                   },
            body: {
                   mode: 'raw',
                   raw: JSON.stringify({
                   "AuthParameters": {
                   "USERNAME": username,
                   "PASSWORD": password
                   },
                  "AuthFlow": "USER_PASSWORD_AUTH",
                  "ClientId": clientId
  }),
options: {
raw: {
language: 'json'
}
}
}
}, function (error, response) {
console.log(response.json());
pm.environment.set("cognitoAccessToken", response.json().AuthenticationResult.AccessToken);
pm.environment.set("cognitoIdToken", response.json().AuthenticationResult.IdToken);
pm.environment.set("token", response.json().AuthenticationResult.AccessToken);
});

Thank you in anticipation...
(Anymore information required - please request - I'll post asap)

Test with valid data to check if it's ok

    Dim Link As String = "https://cognito-idp.us-east-2.amazonaws.com/"
   
    Dim Body As Map = CreateMap("AuthParameters": CreateMap( "username" : "xxx", "password" : "xxx"), "AuthFlow": "USER_PASSWORD_AUTH", "ClientId": "xxx")
    Dim Parameters  As String = Body.As(JSON).ToString
    Log(Parameters)
   
    Wait For (PostURL(Link, Parameters)) Complete (DataResult As String)
   
    Log("---------------")
'    Log(DataResult)
    Log(DataResult.As(JSON).ToMap.As(JSON).ToString)

Public Sub PostURL(URL As String, Parameters As String) As ResumableSub
    Dim Result As String
    Dim j As HttpJob
    Try
        j.Initialize("", Me)
        j.PostString (URL, Parameters)
        j.GetRequest.SetContentType("application/x-amz-json-1.1")
        j.GetRequest.SetHeader("x-amz-target","AWSCognitoIdentityProviderService.InitiateAuth")
        Wait For (j) JobDone(j As HttpJob)
        If j.Success Then
            Result = j.GetString
        Else
            Result = j.Response.ErrorResponse
        End If
    Catch
        Log(LastException)
    End Try
    Log("Status: " & j.Response.StatusCode)
    j.Release
    Return Result
End Sub

Note:
I researched the APIs of AWS services.
and found that member @roumei wrote a class that you can use and modify for the "Cognito" service.

Class : AWSDynamoDB

[B4X] Amazon DynamoDB

Amazon DynamoDB is a NoSQL database service: AWS DynamoDB The attached project (B4J, B4A and B4I) shows how to access Amazon DynamoDB. The relevant code module is 'AWSDynamoDB'. You should first initialize the class with your credentials (put your keys in Main.Process_Globals in order to...

@TILogistic - Thank you so much for the speedy reply and solution - It worked perfectly and thank you also for the further advice on the Class that @roumei made available - I will look into that and modify where I can and repost for the benefit of other members.

This help is greatly appreciated...
