public website with sapui5 and without credentials - sapui5

I want to create public website(actually web page), with some inputs and send the data back to sap. My problem is that the website should be open for everyone and still be connected to sap(which requires username and password).
Is there a way to create sapui5 website without the need to give credentials(and still keep the sap system safe)?

If you do not mean to work with the user information/authentication which I assume is true because you do not want the user to log in, in that case, you can
Create a destination in SCP with basic authentication and store the username and password of the backend system you wish to communicate. An example to refer destination creation in SCP
Deploy the app in the SAP Cloud platform using the destination in your app to post the data.
Hope this should solve your problem.

How to setup google service account authorization in Node.js with JSON key file?

Trying to make use of the Server to Server OAuth flow defined here:
https://developers.google.com/identity/protocols/OAuth2ServiceAccount
Since I'm running from a local dev environment, I've created a service account in GCP and downloaded the JSON file with the private key, but cannot find any Node.js code examples on how to:
1) load the json file
2) set delegated credentials (for G Suite domain-wide authorization)
Places I've looked (besides stackoverflow) are Google's git wiki for the node.js client library, which does talk about server to server auth, but seems to assume you're running from appengine or google cloud and don't need to load a key file:
https://github.com/googleapis/google-api-nodejs-client#service-to-service-authentication
The Admin SDK Activities Reports API has a Node example, but it's using the web-based flow assuming a user is present:
https://developers.google.com/admin-sdk/reports/v1/quickstart/nodejs
Buried deep in the Node.js samples is use of the Directory API, which does seem to take a keyfile as input, but when I try running locally it says getClient is not a constructor, and still this example doesn't show how to set the G Suite admin user for context (which is generally when a refresh token and access token are loaded into the app):
https://github.com/googleapis/google-api-nodejs-client/blob/master/samples/directory_v1/group-delete.js
So... does anybody have an example of this? I really don't want to switch to a Python runtime but Google seems to have left out important examples on this topic.

IBM Cloud API Connect Secure Gateway

Recently, I started seeing an issue when trying to setup secure gateway within API Connect on IBM Cloud, I previously had it working but looks like they changed this wizard interface and its broken since then
here is what I did to recreate the issue:
Setup new APIC instance on IBM Cloud
API connect Manager UI > Admin > Secure Gateways > Add (name & save)
once created, in Secure Gateway Clients section, click on +Set Up
I see no ID or Token generated
no matter what type of client I choose (DataPower, Docker or Installer)
Anyone facing the same issue?
Empty ID and Token when trying to setup Secure Gateway Client
turned out that creating SecureGateway from within the APIC is deprecated feature anyway.
you will need to create standalone SecureGateway resource on Bluemix and call it from your API assembly.
here is the instructions

Retrieve logged user information from cloud foundry web application

We developed a web application using SAP Web-IDE Full Stack; we need to retrieve the details of the user logged into application (as defined in SAP Cloud Platform Identity Authentication Administration), for example display name and assigned groups.
We tried the userapi/currentUser API, but it seems to work only on NEO environment, for this reason is working fine while debugging in Web-IDE, but we get a 404 error when deploying the app on Cloud Foundry.
Do we need to add a new destination to make userapi work also on CF? Or is there some kind of similar solution available on Cloud Foundry?
I highly suggest using the SAP S/4HANA Cloud SDK for such tasks. It is an SDK developed to make building applications for SAP Cloud Platform easy, by providing easy to use mechanisms for all the Cloud Platform mechanisms.
Regarding your task at hand, there is a UserAccessor class that you can use like this:
final Optional<User> user = UserAccessor.getCurrentUser();
This works on Neo as well as on Cloud Foundry, i.e. there is a single interface for both platforms, which allows you to develop your app in a platform agnostic way.
If this sounds like it could solve your problem, I recommend checking out this blog post series to get started.
Alternatively, you can also simply add the following dependency to your project to start testing the SDK:
<dependency>
<groupId>com.sap.cloud.s4hana.cloudplatform</groupId>
<artifactId>scp-neo</artifactId>
<version>2.7.0</version>
</dependency>
For Cloud Foundry use scp-cf instead of scp-neo.
Hope this helps!
P.S.: To answer your question also on a technical level, Cloud Foundry uses so-called JWTs for authentication and authorization. You can check whether a JWT is present by looking at the Authorization header of the request. The JWT should hold the information you're looking for.
In SAP Cloud Foundry if you develop a MTA using XSUAA service to manage User Authentication and Admistration, defined for example in the mta.yaml,
...
resources:
- name: uaa_myapp
parameters:
path: ./xs-security.json
service-plan: application
service: xsuaa
type: org.cloudfoundry.managed-service
...
you can use the UAA API published from XSUAA service self to manage user authentication and authorization (e.g.: retrieve user info, groups assigned, password management etc..). also in the case the application is federated with another IDP.
To consume this API for example to retrieve user info you need to:
Determine the XSUAA endpoint bound to your app (SCP Cockpit > XSUAA service detail > take the value url)
Create a destination (xsuaa_api_destination) of type OAuth2TokenExchange bound to your app with url url took before, and fill OAuth2 authentication parameters with the data contained in XSUAA service detail (step 1).
From your app execute the call xsuaa_api_destination/userinfo, for example using an ajax if you are using JS.
You can find other info in Account and Authentication Service of the Cloud Foundry Environment SAP doc.

Deploy a business network on bluemix

I use this tutorial to deploy a business network on a free bluemix cluster: https://ibm-blockchain.github.io/
I also deploy the REST Server and communicate via Web apps.
All went fine till yesterday. The REST Server was not accessible anymore.
I deleted everything on the cluster using the script delete_all available in the ibm-container-service repository.
I followed the install procedure using the create_all script. I could access the composer playground (port 31080) again but was not really able to deploy an online business network using the "profile" hlfv1. Now it asks at the bottom of the "deploy UI" for credentials.
I don't know what to fill in. I tried to use ID+Password. On this way I was able to deploy but I got access error by clicking on "connect now". I was able to start the REST server then but if i try to access it in the browser (port 31090), I get the feedback that I'm not authorized.
Any ideas?
And do you know which changes have been made in the last month, which could bring these troubles?
Thx
Phil
The tutorial pointed to only covers playground when used with a Web Browser connection not a real fabric. When you deploy to a real fabric you have to provide an initial identity that you want bound to an initial participant in the business network. The initial participant will be of type org.hyperledger.composer.system.NetworkAdmin and given a name of the initial identity name you provide.
This dialog looks like this
To get you started you should select the ID and Secret radio button. Then for Enrollment ID enter admin and for the Enrollment Secret enter adminpw.
This is the name and secret of the bootstrap identity that exists in the fabric-ca server that has been deployed as part of the scripts.
By providing this information that identity will be enrolled and it's public certificate will be bound to a NetworkAdmin participant which will be called admin. This identity admin will then have access to the business network as only identities that are bound to a participant in the business network can have any sort of access.

Google for Work not connected to Google Developers Console

We have been using Google for Work for years now and have a domain setup thru godaddy. We got it so we would have a descent email server without having to worry about it. I then signed up for the Google Developers Console to expand the options we have available and move our local apache/php business software to the cloud. I correctly setup a project with a lamp instance which also works great.
Problem is I cant add projects thru the
https://console.developers.google.com/project?authuser=0
it returns
Error Developers Console has not been activated for your account.
Your account may be suspended or disabled. If you are a Google Apps
user, ask your domain administrator to enable Apphosting Admin on your
account.
But from here I can add new projects
https://code.google.com/apis/console
If I goto the Google for Work console App Engine apps it says
No services have been installed.
Add services to your domain
I click the link to add the service
and goto the Other Services
Google App Engine Provide existing Google App Engine services to your
users.
Enter App ID:*
What is the App ID? I have already authorized the domain we are using for the services.
If I goto Google for Work Domain admin and try to add the other domain we have it says
We are sorry, but you do not have access to Webmaster tool. Please log
in to your Admin Console to enable Webmaster tool. Learn more
Its also adding the domain name to the Project ID: which causes this error in the SDK console

Im really confused
Go to admin.google.com, login with our organisation account, go to Apps -> Additional Google Services -> Enable the services you need.
