Hyperledger Composer ping on REST multi-user mode: ECONNREFUSED for issued identities from single user REST

问题

Following: https://hyperledger.github.io/composer/v0.19/tutorials/google_oauth2_rest

I have the same problem of:

Hyperledger Composer multi-user mode: ECONNREFUSED for issued identities

Basically, i have two rest server and when i issue a id from port 3001 (admin card single user) then import and try to ping on port 3000 (multi-user), the same error appears. Seems like the card are being imported with the wrong hostname.

But i can't do the same that the user says: " I changed the URLs over there instead of modifying the cards after creating them. This has solved the issue as now the cards are generated with proper container URLs rather than localhost. "

When i do

composer identity issue -c admin@amachains -f restadmin.card -u restadmin -a "resource:org.hyperledger.composer.system.NetworkAdmin#restadmin"

composer card import -f restadmin.card

composer network ping -c restadmin@amachains

cd ..

sed -e 's/localhost:7051/peer0.org1.example.com:7051/' -e 's/localhost:7053/peer0.org1.example.com:7053/' -e 's/localhost:7054/ca.org1.example.com:7054/'  -e 's/localhost:7050/orderer.example.com:7050/'  < $HOME/.composer/cards/restadmin@amachains/connection.json  > /tmp/connection.json && cp -p /tmp/connection.json $HOME/.composer/cards/restadmin@amachains/

and then export this and import in 3000 rest server, the ping works.

That is my script for start my whole project:

# !/bin/bash
sudo kill $(sudo lsof -t -i:3000)

sudo kill $(sudo lsof -t -i:3001)

sudo kill $(sudo lsof -t -i:4200)
