问题描述

我正在尝试设置 Hyperledger Composer Rest Server (

i'm trying to set up the Hyperledger Composer Rest Server (https://hyperledger.github.io/composer/reference/rest-server) in order to work with Cloudant DB on IBM Cloud and store inside it the cards used to interact with the blockchain.

In particular i would like to know how to configure the COMPOSER_DATASOURCES parameter of composer-rest-server.

推荐答案

Composer Rest Server使用回送，因此 COMPOSER_DATASOURCES 是回溯数据源.为了使用cloudant，您需要使用npm安装loopback-conector-cloudant，然后将数据源设置为:

The Composer Rest Server uses loopback, and so the COMPOSER_DATASOURCES are lookback datasources. In order to use cloudant you would need to use npm to install loopback-conector-cloudant, and then set the data source to be something like:

"mydb": {
  "name": "mydb",
  "connector": "cloudant",
  "username": "XXXX-bluemix",
  "password": "YYYYYYYYYYYY",
  "database": "test"
}

此处有很好的详细文档环回.

There is good detailed documentation here from loopback.
