Hyperledger-Composer REST Authentication - hyperledger-composer

Request assistance with hyperledger composer. I have created a network and web app around the REST API that was built with the composer-rest-server. I am able to add participants, assets and execute transaction with the default settings. I am now trying to add authentication to the REST server as well as add identities to new participants. However I got stuck. I have reviewed the information at
https://hyperledger.github.io/composer/integrating/enabling-rest-authentication.html
But I'm not sure where I should place the export COMPOSER_PROVIDERS='{.... information to continue the setup.
Any assistance, tips and tricks are much appreciated.

Ok so I figured it out. The problem was that I was running off an older version of composer-rest-server.
I installed the developer tool back in Sep 17 and did the tutorial soon after. I tried the tutorial again and noticed that the deployment command was different and it would not let me deploy my network.
So I updated the composer-rest-server and component cli and it deployed fine. I then followed the steps on the authentication webpage that I referenced above and it worked as intended. I deployed my personal network with the new command and it worked as intended.
Lesson learned this stuff is still being updated and I should be more aware on what changes. Thank you very much #nilakantha singh deo

Open a new terminal from inside the project folder.Format your COMPOSER_PROVIDERS in notepad according to the document you mentioned and copy the whole message and paste it in the terminal.Then you can echo it (see it) by typing the following.
echo $COMPOSER_PROVIDERS
It should ideally return the same json file.
Then make sure that the compopser-rest-server is running with multiuser mode and authentication enabled in the same terminal where you echoed and saw the COMPOSER_PROVIDERS.
In browser now type
localhost:3000/auth/github
It should ask for authentication .Rest of the steps are listed in the document you mentioned.
Cheers!

On the google cloud console website in the APIs & Services I can't change a credential package in to an old package name?

This is the screen I get when I try to change the credentials:
I had made previously a credential using that package name:"com.CavernHead.MostAnnoyingChat" and then later deleted because I wanted to start over making my credentials on a clean slate. It seems that something about the old credentials still remain and is stopping me from changing my package name to the old one. I'm not even sure if it's essential for what i'm doing but it could be so I want to change the package name to com.CavernHead.MostAnnoyingChat.
just for context I ran in to this issue while trying to follow this tutorial and implement google sign in with playfab: https://learn.microsoft.com/en-us/gaming/playfab/features/authentication/platform-specific-authentication/google-sign-in-unity
Any help would be highly appreciated
thanks.

how to debug during API with laravel

I run my laravel app #localhost.
```php artisan serve --host=localhostIP```
On top I run an Andoid app with the same base URL.
Could anyone tell me how can I debug incoming API´s calls
like if BASEURL/users is called?
Furthermore, how can I log the happening events in the console
I am developing API's with laravel too, i do it this way:
composer require laravel/homestead to have it all in a vm 😉 see https://laravel.com/docs/master/homestead for more information, i use the "per project" installation
Download postman to have the best tool for sending querys to your api and to test your api quick -> https://www.getpostman.com (i use it free)
configure and run your homestead (it's not that complicated).
your homestead is fit with php and xdebug enabled
i am using phpStorm and have my vagrant setup as deployment target
"listen to debug" with phpstorm
to your GET requests, add a queryparam XDEBUG_SESSION_START=PHPSTORM
i can debug my api now 😉
i also wrote https://logcrawler.de to receive the log informations of all my api's and all my server 🤩
I hope, i could help you a little bit
This is my way, but I think it's not good!
Create router api in config/web, Eg:
router/api: Route::post('/check_api', [CheckController::class, 'testFunc'])->name('api.check_api');
web/api: Route::post('test/check_api', [CheckController::class, 'testFunc'])->name('test.check_api');
Create a post by form or ajax in one resource/view like index
Go to page, and debug with phpstorm
You can use logging feature of Laravel. Apply Logs on entry point of application to test whether API url is hitting or not.
use postman

it's an excellent thing very much usefull

Google Sheets API Java program, works on one machine and not the other - 401 Au

I've got a working basic Java App that uploads some data to a google sheets file of mine.
I uploaded it to a git client, pulled it to my other computer, and it doesn't work on that with a 401
Exception in thread "main" com.google.api.client.auth.oauth2.TokenResponseException: 401 Unauthorized

Any idea what could be different between the two machines? I understand it that if I'm using the same client_secret.json, it should be irrelevant which machine I'm on?
UDPATE 1:
ok, some extra info - i just tried my project at work on my work laptop and it worked fine! On first run it opened a browser window and asked me which google account I wanted to use, I chose the correct one, and that worked. On the laptop I have that didn't work, I wasn't given that option (that I remember) so how can I reset the google account that has been used to authenticate against?
I saw this in my cmd line
Please open the following address in your browser:
https://accounts.google.com/o/oauth2/auth?access_type=offline&client_id=blah-notputtingmyrealid.apps.googleusercontent.com&redirect_uri=http://localhost:42299/Callback&response_type=code&scope=https://www.googleapis.com/auth/spreadsheets
Attempting to open that address in the default browser now...
Since it's working on your previous computer, the issue might be concerning the location of your client_secret.json. If you check the Java Quickstart setup, there's a part where you need to download the JSON file and place it on your working directory. Since, you're on a new machine, that file is now missing.
g. Click the file_download (Download JSON) button to the right of the
client ID.
h. Move this file to your working directory and rename it
client_secret.json.
Or the access token has expired.

"New version available" with service worker and sw-precache

I'm trying to use sw-precache, but I must be doing something wrong!
I'm mostly using the demo code available from the github repo and can't seem to get updates to the app to come through. Once it's cached the first time, it never checks for new versions.
I was expecting that when I publish a new service worker, the browser would request the new service worker and update the cache accordingly in the background. Then using the registration code in the example, I would be able to prompt the user to refresh and get the latest version from their newly refreshed cache.
Would really appreciate if someone could please point me in the right direction.
Example
To demonstrate the problem, I've created an isolated example here:
https://github.com/stevenocchipinti/sw-precache-demo
The example uses a basic skeleton from create-react-app which has a built in build task which take care of fingerprinting the filenames, etc.
I suspect the problem is with me caching everything by using the following sw-precache config:
{
"staticFileGlobs": [ "build/**/*.*" ],
"stripPrefix": "build/"
}
There are more accurate steps in the repo's readme, but the basic steps I'm taking to reproduce the problem are as follows (with my probably incorrect expectations).
Steps and Assumptions
Browse to the app for the first
I should see Content is now available offline! in the console
Reload the page
The message in the console should not appear again because the service worker is installed, but the page should still work.
Go offline and reload the page
The page should still work
Make a visible change to the source code
Rebuild (run the build task and sw-precache)
This is where my understanding must be wrong
Reload the page
The service worker should update the cache in the background
When its done, you should see New or updated content is available. in the console
The actual visible changes should not be visible until the next reload
Reload the page again
The browser will use the new cache this time around
The changes should be visible now!
There shouldn't be any messages in the console
The problem
Once the app has been cached initially, it will never update unless you unregister the service worker or force a reload.
I'm not sure how to make this work - any help would be greatly appreciated!
After replicating your development hosting environment, I can see that you're serving your service-worker.js file with a browser HTTP cache lifetime of one hour:
There's more information as to why this is leading to the behavior you're seeing, along with best practices, in this previous answer. As mentioned at the top of that answer, browsers plan on changing their behavior to stop honoring the HTTP cache for the service worker file by default, mainly due to the type of confusion that you're experiencing here. For the time being, though, the production versions of both Chrome and Firefox continue to honor those headers.

Error 404 for rest webservice request in offline app in GeneXus Ev3 U9

I'm developing an offline Android app with Genexus Ev3 U9 and when I try the app in the device I see there is no initial synchronization, even when I try to execute a manual sync the app shuts down. The cat log shows that request made to URLs like http://192.168.12.17/MyAppSmartDevicesEnvironment/gxmetadata/MyApp.android.json
worked fine but when the app tries to get this URL http://192.168.12.17/MyAppSmartDevicesEnvironment/rest/MyAppOfflineDatabase?fmt=json&event=gxchecksync returns 404 I tried the same link in my laptop and it's like the requested resource was not created by GeneXus.
What could be wrong?
There are actually a couple of things you might want to check.
When you accessed http://192.168.12.17/MyAppSmartDevicesEnvironment/gxmetadata/MyApp.android.json you got data but that just means that the virtual directory was successfully created. (which is good of course)
Then you need to check if the WCF module is installed correctly, in order to do that you could try to go to http://192.168.12.17/MyAppSmartDevicesEnvironment/MyAppOfflineDatabase.svc/rest or any other service in your KB. That goes straight to the service implementation. (you can check you web.config file in order to see the actual rewriting rules)
If that works it's certainly a URL Rewrite problem like Sandro and Guscarr suggested.
You can download and install the module from here: http://www.iis.net/downloads/microsoft/url-rewrite
Gcastano,
It seems that you're generating to .net, right?
If so, it could be some problem with iis rewrite module.
Anyway you might check gx software requirements...
It seems that REST services cannot be run on your IIS, as Sandro said, try installing URLRewrite.
