Blockchain as a Service:Environment Interface

This document describes how to use Chain to initialize an environment instance.

1. Introduce the JS SDK.

   Use the TLS protocol based on the node environment.

   const Chain = require('@alipay/mychain/index.node')

2. Create a connection instance.

   Take the creation of connection instances in the node environment as an example.

   const Chain = require("@alipay/mychain/index.node") // Use the TLS protocol in the node environment
   const fs = require("fs")
   const accountKey = fs.readFileSync("./certs/user.pem", { encoding: "utf8" })
   const accountPassword = "123abc"  // To be replaced with the user-defined user.pem password
   const keyInfo = Chain.utils.getKeyInfo(accountKey, accountPassword)
   const passphrase = "123abc" // To be replaced with the user-defined client.key password
   //Configuration items
   let opt = {
     host: '127.0.0.1',    //IP of the target blockchain node
     port: 18130,          //Port number
     timeout: 30000,       //Time configuration for the connection timeout period
     cert: fs.readFileSync("./certs/client.crt", { encoding: "utf8" }),
     ca: fs.readFileSync("./certs/ca.crt", { encoding: "utf8" }),
     key: fs.readFileSync("./certs/client.key", { encoding: "utf8" }),
     userPublicKey: keyInfo.publicKey,
     userPrivateKey: keyInfo.privateKey,
     userRecoverPublicKey: keyInfo.publicKey,
     userRecoverPrivateKey: keyInfo.privateKey,
     passphrase: passphrase
   }
   //Initialize a connection instance
   const chain = Chain(opt)
