How to query what the worklight server host information is in hybrid app

Question 1

I did a little more investigation and was able to write a cordova plugin for android and ios to read in the value from the prospective property files that WL generates. Below are the different sources. See WorkLight Getting Started Section 6 for more information on writing a cordova plugin. It was actually fairly easy. Once you get past how... different Objective-C is, it took just a few minutes.

Android code

WorklightPropertiesPlugin.java

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;

import android.content.res.AssetManager;
import android.content.res.Resources;

public class WorklightPropertiesPlugin extends CordovaPlugin {
    @Override
    public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
        boolean handled = false;
        String responseText = "";
        if(action.equalsIgnoreCase("serverURL")) {
            try {
                AssetManager am = this.cordova.getActivity().getApplicationContext().getAssets();
                InputStream is = am.open("wlclient.properties");
                Properties prop = new Properties();
                prop.load(is);
                String wlServerProtocol = prop.getProperty("wlServerProtocol");
                String wlServerHost = prop.getProperty("wlServerHost");
                String wlServerPort = prop.getProperty("wlServerPort");
                String wlServerContext = prop.getProperty("wlServerContext");
                responseText = wlServerProtocol + "://" + wlServerHost + ":" + wlServerPort + wlServerContext;
                handled = true;
            } catch(IOException e) {
                callbackContext.error("Error loading properties " + e.getLocalizedMessage());
            }
        }
        if(handled) {
            callbackContext.success(responseText);
        }
        return handled;
    }
}

iOS code

WorklightPropertiesPlugin.h

#import <Foundation/Foundation.h>
#import <Cordova/CDV.h>

@interface WorklightPropertiesPlugin : CDVPlugin

- (void) serverURL:(CDVInvokedUrlCommand*) command;

@end

WorklightPropertiesPlugin.m

#import "WorklightPropertiesPlugin.h"

@implementation WorklightPropertiesPlugin

- (void) serverURL:(CDVInvokedUrlCommand*)command{
    NSString * response = nil;
    CDVPluginResult *pluginResult = nil;

    NSString* plistLoc =[[NSBundle mainBundle]pathForResource:@"worklight" ofType:@"plist"];
    if(plistLoc == nil){
        [NSException raise:@"[Remote Load Initialization Error]" format:@"Unable to locate worklight.plist"];
    }

    NSDictionary* wlProps = [NSDictionary dictionaryWithContentsOfFile:plistLoc];
    NSString* proto = [wlProps valueForKey:@"protocol"];
    NSString* host = [wlProps valueForKey:@"host"];
    NSString* port = [wlProps valueForKey:@"port"];
    NSString* wlServerContext = [wlProps valueForKey:@"wlServerContext"];

    if(proto == nil || host == nil || port == nil){
        [NSException raise:@"[Remote Load Initialization Error]" format:@"host, port and protocol are all required keys in worklight.plist"];
    }

    response = [NSString stringWithFormat:@"%@://%@:%@%@", proto, host, port, wlServerContext];

    pluginResult = [CDVPluginResult resultWithStatus: CDVCommandStatus_OK messageAsString:response];
    [self.commandDelegate sendPluginResult:pluginResult callbackId:command.callbackId];
}

@end

Question 2

In Worklight, these properties are not exposed to the client-side.
You can submit a feature request.

Some alternatives:

Re-route/Divert some WL.Client Adapter Invocation traffic to WL Server through different URL (for PCI payment and security requirements)?
Detect Worklight Server Hostname/IP Address from Worklight Client code
Is it possible to access to the HTTPRequest in the worklight adapter implementation?
