About Predix SDK for Hybrid The Predix SDK for Hybrid includes Reference App Containers for various platforms, the pm command-line tool, and several services that help you to extend the container. A Mobile Reference App Container is a native application that includes the Predix Mobile Client Core Services framework that enables you to load, display, and run your Predix Mobile applications. • For Android, you build the Predix Mobile Reference App Container for Android. • For iOS, you build the Predix Mobile Reference App Container for iOS. • For MacOS, you build the App Container for MacOS. The Predix Mobile (pm) command-line tool allows you to manage your Predix Mobile apps and your mobile back-end processes. The pm CLI commands depend on the Cloud Foundry and UAAC command-line tools, so make sure they are installed and properly configured prior to installing the pm tool. See Predix Mobile Command-Line Interface (pm CLI) Commands on page 3. The SDK for Hybrid provides several services as REST APIs to provide functionality to hybrid or native Mobile applications. The Client SDK consuming application (Predix Mobile App Container) can interact with these local services following this general URL structure: http://pmapi//. The Predix Mobile Reference App Container interprets URL requests and delegates them to the services in the Predix Mobile Client Core Services framework , which respond with a JSON payload describing the result of the call. See Predix Mobile Client Core Services Framework on page 14.

Predix Mobile Command-Line Interface (pm CLI) Commands Predix Mobile command-line interface (pm CLI) is a set of command line utility tools Use the pm CLI to manage your Predix Mobile apps and Mobile Service processes. The pm CLI includes a set of commands that are invoked through the pm command-line interface. The pm CLI commands use the following syntax:

pm [options] [command]

Installing the pm Command-Line Interface Use the pm CLI to manage Predix mobile users, roles, Predix mobile applications, and their web app dependencies.

Before You Begin The pm CLI depends on both the Cloud Foundry (CF) and UAAC command-line tools. • Install Cloud Foundry's cf CLI. See https://github.com/cloudfoundry/cli#downloads. • Install Cloud Foundry's cf-uaac CLI. See https://github.com/cloudfoundry/cf-uaac and Troubleshooting UAA Service on page 25.

About This Task Install the pm CLI:

Procedure • Download the pm .zip file from https://github.com/PredixDev/predix-mobile-cli/releases/latest. ◦ For iOS and MacOS platforms, unpack the pm-v1.x.x-Mac.zip file in your workspace. ◦ On the Windows platform, unpack the pm-v1.x.x-win.zip file in your workspace. pm api Use this command to display the current target, set the target, or change the target Predix Mobile Client API Gateway service. In a typical application-development workflow, you begin by targeting the Predix Mobile Client API Gateway service. The Client API Gateway and the UAA Service work together to ensure that all clients that access the Predix Mobile service possess a valid authentication token. In this example, the command returns an empty target.

The pm publish command takes a –webapp parameter that specifies the path to a webapp.json file. This file defines the web application to be published. The publish command grants access permission to the current authenticated user so you can load the app initially with the user account used for publishing. See the pm grant command for information on granting access to additional users.

© 2020 General Electric Company 9 pm revoke Use this command to revoke access to a Predix Mobile app for a specified user account. The pm revoke command requires a single parameter specifying a Predix Mobile app by name or a path to an app.json file. By default it operates on the current authenticated user. However, it also takes a -- user parameter where you can specify a different user for access revocation.

pm routes Use this command to list all defined routes that the Predix Command Router is aware of. These routes are used to route commands to individual command processors, which are microservices that you deploy using Cloud Foundry cf tools. Any document created from your Predix Mobile web app with a type equal to command can be routed to a command processor and processed. A command router is a microservice that is tasked with routing pending command documents to configured command processors. A command document is a JSON document with a type field value as command and a status field. The command document format is similar to an HTTP request, with a request and response section contained in the same document. The Command Router manages the state of a given command from the time the document arrives on the server until the router writes the result from an invoked Command Processor to the response section of the document. The Command Router translates a command document into an equivalent HTTP request to a Command Processor. The HTTP response from the Command Processor is serialized and placed in the response section of the originating command document.

Configuration Preferences and Properties The Predix Mobile SDK has two types of on-device configuration storage: Preferences and Properties. Application users can change Preferences on a device, whereas a developer sets Properties at compile- time.

Preferences Preferences consist of developer-set defaults, user-changeable current values, and a user interface to change those values. For iOS, the Preferences defaults are stored in the Mobile applications root.plist file in Xcode. The Preferences defaults are used to populate the iOS and the macOS’s standard UserDefaults object. In iOS, the user can manipulate those values using the standard iOS Settings app. For macOS, since there is no standard Settings app, the reference app container includes a Preferences user interface that you can mimic to construct your own UI for these values, and then that UI can update those values in the UserDefaults object. For Android, the default values are stored in assets/preference_defaults.properties file in the application's Android Studio project, and the storage implementation uses the Android SharedPreferences object, along with a sample UI provided in the reference app container. By default, the server endpoint and default logging level is stored in Preferences, however again, this can be changed using the PredixMobileConfiguration class. The defaults are shown in the table below.

Properties Because properties are set by the developer at compile-time, they are read-only configuration elements for users, and are not expected to change. In the iOS and macOS implementations of the Predix Mobile SDK, Properties are stored in the application project’s info.plist file. For Android, properties are expected to be in the resources/config.properties file; although this filename can be changed by updating the configurationPropertiesFilename property of the PredixMobileConfiguration class. By default the pm-app name and version configuration is stored in Properties on the iOS, macOS, and the Android implementations of the Predix Mobile SDK. However, this can be changed by updating the appropriate properties in the PredixMobileConfiguration object. The defaults are shown in the table below.

Configuration element Key Name Property Location Property

Predix Mobile app name pmappDocumentNameKey pmappDocumentNameConfig Location

Predix Mobile app version pmappDocumentVersionKey pmappDocumentVersionCon figLocation

Server endpoint serverEndpointConfigKey ServerEndpointConfigLoc ation

Logging level loggingLevelConfigKey loggingLevelConfigLocat ion

Other values may be stored in Preferences and Properties as needed, depending on the platform implementation. Refer to the exposed properties of the platform’s configuration control class.

Example Configuration Changes

Change App Document Name Key To change the key used to extract the Predix Mobile app name from configuration from the default pmapp_name toPredixMobileAppName: iOS/MacOS PredixMobilityConfiguration.pmappDocumentNameKey = "PredixMobileAppName" Android/Java PredixMobileConfiguration.pmappDocumentNameKey = "PredixMobileAppName";

Change App Name Configuration Location To change the location used to retrieve the Predix Mobile app name from the default Properties configuration to the Preferences configuration: iOS/MacOS PredixMobilityConfiguration.pmappDocumentNameConfigLocation = ConfigurationLocation.settings Android/Java PredixMobileConfiguration.pmappDocumentNameConfigLocation = PredixMobileConfiguration.ConfigurationLocation.PREFERENCES;

Troubleshooting UAA Service The following are general troubleshooting tips and issues you may experience when using Security services. • Troubleshooting UAA Command Line Interface (UAAC) Installation Issues • Troubleshooting Oauth2 Issues

Troubleshooting UAA Command Line Interface (UAAC) Installation Issues There are a number of ways you can install UAAC. The procedure lists recommended installation steps for Windows and Linux users. Windows 1. Install Ruby from http://rubyinstaller.org/downloads. Use the stable version of Ruby (version 2.1.x). Note: The 64-bit versions of Ruby are relatively new and not all the packages have been updated to be compatible with it. To use the 64-bit version you will require compiler knowledge, and you will need to be prepared to solve dependency issues. 2. Install the Ruby development kit. Follow the installation steps at https://github.com/oneclick/rubyinstaller/wiki/Development-Kit. 3. Download Gem for UAAC, cf-uaac*.gem, from https://rubygems.org/gems/cf-uaac. 4. Install the cf-uaac*.gem gem.

gem install cf-uaac*.gem 5. Test if the installation was successful.

uaac help

Linux Installation of UAAC on Linux or Mac is easier if you use the bundler gem to install all the required dependencies for cf-uaac gem install. 1. Verify that the Ruby version of Ruby is a stable version (version 2.1.x).

ruby --version 2. Download Gem for Bundler, bundler.gem, from https://rubygems.org/gems/bundler. 3. Install the bundler gem.

gem install bundler 4. Generate a Gemfile with the default rubygems.org source.

bundle init

The Gemfile is created in the same location as the bundler gem.

# A sample Gemfile source "https://rubygems.org"

# gem "rails" gem 'nokogiri' gem 'rack', '~>1.1' gem 'rspec', :require => 'spec' gem 'cf-uaac' 6. Install all of the required gems from your specified sources.

bundle install 7. Install the cf-uaac gem.

gem install cf-uaac 8. Test to see if the installation was successful.

Troubleshooting Oauth2 Issues Predix platform services use OAuth2 for authentication. Errors related to OAuth2 include the HTTP 401 Authorization error. To troubleshoot an OAuth2 issue, check the claims in a user or application token. For example, if you receive an HTTP 401 authorization error, you need to make sure that the token was issued from the correct UAA (iss claim) with the required scopes (scope). Caution: Using online tools to decode tokens comes with several risks. If a token is stolen, it can be used by anyone to access protected resources without any other credentials. Even after a token expires, its claims information exposes internal details about Predix applications and systems, which can be used to help in other attacks. Use the following tools to decode tokens on your local machine: • UAAC Use the following command to decode a token:

uaac token decode

Example:

uaac token decode eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJodHRwczovLzEyMzQxMzQz MTI 0MTMubXktZG9tYWluLmNvbS9vYXV0aC90b2tlbiIsInNjb3BlIjoidGVzdCIsInN1YiI6 Imp vZUBleGFtcGxlLmNvbSJ9.KGzJ12fOqBF2sxi9F3oFG3FDWBmNES9TU2j7yc_XyP0

Note: no key given to validate token signature

iss: https://1234134312413.my-domain.com/oauth/token scope: test sub: [email protected]

26 © 2020 General Electric Company Note: As indicated in the UAAC output message, you can provide a public key to validate the issuer of the token. • Base64 The JWT claims are Base64-encoded JSON. If you do not need to validate the JWT issuer, use a tool that can decode the token claims section. A JWT token uses the following format:

base64encoded_header.base64encoded_claims.signature

Use the following command to list the claims:

echo | cut -f 2 -d . | base64 --decode

Example:

~/dev$ echo 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJodHRwczovLzEyMzQxM zQzMTI0MTMubXktZG9tYWluLmNvbS9vYXV0aC90b2tlbiIsInNjb3BlIjoidGVzdCIsIn N1Y iI6ImpvZUBleGFtcGxlLmNvbSJ9.KGzJ12fOqBF2sxi9F3oFG3FDWBmNES9TU2j7yc_Xy P0' | cut -f 2 -d . | base64 --decode {"iss":"https://1234134312413.my-domain.com/oauth/ token","scope":"test","sub":"[email protected]"}

~/dev$

SSLException while targeting a UAA instance using UAAC When targeting multiple UAA instances using UAAC, the client is able to authenticate some UAA instances successfully, but for others it generates an SSLException. Cause One probable cause of this issue is your proxy settings. Additionally the versions of UAAC, Ruby, and OpenSSL that you are using do not support a new GE certificate and you need to be able to accept TLS1.2 connections. Solution As a workaround, you can use the --skip-ssl-validation flag. Use the following command to check the SSL certificate:

openssl ciphers -v | awk '{print $2}' | sort | uniq

Use the latest versions of UAAC, Ruby and OpenSSL.

Condition When adding a user to authenticate as part of granting rights to use your app using the pm grant command, you receive a message that user account is not found.

Cause The username is not valid.

Solution When you grant access using the pm grant command, the user name entered must match the user account set up in a corresponding UAA instance. For more information on creating a user in UAA, see Creating Users in a UAA Instance.

User Token Invalid - Expired When adding a user to use a Predix Mobile app, you receive a message that the user token has expired.

Condition When adding a user to authenticate as part of granting rights to use your app, you receive a message that the user token is expired:

{ "error": "invalid_token", "error_description": "Invalid access token (expired): ... expired at Sat Nov 14 15:51:53 UTC 2015" }

Cause The user has been added, but the token ID (id.url) for the user has expired.

Solution Use the following pm-cli command to fetch the correct token for the user (where "admin" is the example user you are trying to add):

uaac token client get admin -s PredixMobile

The command returns the target and context for the user. The following sample shows a successful response:

Successfully fetched token via client credentials grant. Target: https://894c559b-430a-4d10-83e8-b6ded9e46ced.

Authentication Not Valid when Creating User

Condition When you run the pm-add-developer script to create a developer user on the UAA server and grants them access to the pm.admin group, you get an authentication error.

Cause The user has been added, but the token ID (id.url) for the user has expired.

Solution Try re-logging into the UAA server, using the standard uaac commands, and then execute the user creation operation again:

$> uaac target --skip-ssl-validation $> uaac token client get (enter UAA admin password when prompted)

Running pm CLI in Debug Mode Use debug mode to troubleshoot pm CLI commands that produce error messages.

Condition When running a pm command, you receive an error message.

Solution Run the command in debug mode. The following example shows the syntax for running the pm auth command in debug mode:

pm auth --debug user password

You should see output similar to the following:

HTTP-Util: GetResource: request options: { "method": "GET", "url": "617421.grc-apps.svc.ice.ge.com/login", "headers": { "User-Agent": "pm-cli 1.0", "Accept": "application/json", "Content-Type": "application/json" }, "json": true}

Developing Apps for Apple Devices

Build an App with Native iOS Components Use this sample code as a model for creating a native iOS app. This example shows how to create a native iOS app that is similar to the hybrid issues-tracking Sample app. It uses a native UI instead of a hybrid one. Native apps can be used to create entire iOS apps, or components of larger native or hybrid apps that require a particular native look and feed, or for performance reasons, and so on. This example demonstrates a number of techniques, including creating database views, calling services from native Swift code, and using properties from the web app document to determine what native components to load. To learn how to create a non-hybrid, native iOS app with the Mobile SDK see https://github.com/ PredixDev/MobileExample-iOS-NativeIssuesListApp.

Submitting a Predix Mobile Container to the Apple App Store Use the Apple Enterprise license program to publish apps for general consumption.

About This Task Many companies that develop mobile software use internal IT groups and procedures to publish apps in the Apple App Store. If your app’s audience is exclusively composed of company employees, your company may qualify for the Apple Enterprise license program. This program allows you to internally publish apps without going through the App Store and making your app available to the general public. Because an app distributed through the Enterprise license program does not get published to the App Store, the app is not subject to the strict review requirements that public App Store apps must pass. See the Apple developer site for more details: https://developer.apple.com/programs/enterprise/. If your app is intended for a larger audience than company employees, then it must be published in the App Store for distribution. Software development for devices must meet specific Apple iOS requirements. The App Store Distribution Tutorial is a key starting point in the Apple content repository. Follow these general steps to register your app in the App Store:

Procedure 1. Register as an Apple Developer: https://developer.apple.com/programs/. 2. Create your app’s bundle ID, App Store distribution certificate, and provisioning profile on the Apple Developer site. 3. Build and sign your app in XCode. 4. Create the app entry in iTunesConnect, including your screenshots, description, keywords, support URL, and any other required information. 5. Upload your app binary files to iTunesConnect.

© 2020 General Electric Company 31 Apple reviews your app, generally within two weeks. New apps are automatically published after approval. If Apple rejects your app, the rejection email includes details. You can then address the problem and resubmit.
