Hyperledger Composer add a new peer

由 不打扰是莪最后的温柔 提交于 2019-12-08 09:14:29
问题 I am modifying existing docker-compose.yml, crypto-config.yaml and configtx.yaml to add a extra peer to the existing hyperledger composer sample, located under hlfv11 folder of the fabric-tools/fabric-scripts. I regenerated required certificates and genesis block and it generates the peer container without any issue. However I am having difficulty adding this peer to a channel. I modified startFabric.sh to join this peer to a channel, however I am getting an error with following message:

transactionId when submitting a transaction

问题 I am trying to submit a transaction using "composer transaction submit...". I get an error stating that transactionId value is missing... the transaction is accepted only if I add a random transactionId, but in Playground the JSON used to submit a transaction does not include transactionId and is executed OK (although I know it is the javascript Fabric emulator embedded in Playground). So, in order to submit transactions using CLI or REST API, how should I generate/know the transaction Id if

问题 Say I just wanted to get a list of all transactions that involved a specific asset (assuming I would need a query for this?). Should I use the TransactionRegistry or the Historian? What's the difference? 回答1: furthermore, to see the transaction data (deltas) for the asset id you're zoning in on - ie available through the transactionInvoked field of the transaction class (eg org.acme.trading.Trade transaction class). you could use REST APIs with loopback filters -eg either (both return a

Composer REST server auth

问题 I have a question about rest-server. In my project I don't won't to use rest server as direct backend, I wanna have one more api, which will send different requests. So, my question is, what kind of auth I need to choose? (auth need for multi-user mode, I want to send transactions from different participants) Thank you) Is it possible to use composer-rest-server not just for log in but for sign up too, if real users will not make requests, but my own api will register them on rest-server

I can also access the application (port 4200), but when I try to interact with it I get the following: Error: Could not connect to REST

Fabric Composer quick-start failing when trying to deploy the bna file on OSX

由 久未见 提交于 2019-12-08 03:47:28
I'm having some problems trying to deploy a bna file using the fabric composer. First I tried using my own HyperLedger 0.6 instance, creating a connection profile and then using the composer-cli to deploy a bna and I got the following error during the composer network deploy command: "TypeError: Cannot read property 'fail' of undefined" Then I removed all my docker images and containers, made sure everything was updated and I tried the getting-started script and I got the exact same error. The steps I followed are the following: I'm using Docker 17.03.1-ce-mac5 stable on OSX 10.12.4 I cloned
