交易
为了能够在区块链上发送交易和触发操作，你必须具有 Api 实例。
签名提供程序必须包含与执行者和操作权限相对应的私钥。
const {Api, JsonRpc} = require(‘eosjs’);
const JsSignatureProvider = require(‘eosjs/dist/eosjs-jssig’); // development only
const fetch = require(‘node-fetch’); // node only; not needed in browsers
const {TextDecoder, TextEncoder} = require(‘text-encoding’); // node, IE11 and IE Edge Browsers

const privateKeys = [privateKey1];

const signatureProvider = new JsSignatureProvider(privateKeys);
const rpc = new JsonRpc(‘http://127.0.0.1:8888’, { fetch});
const api = new Api({rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder()});
示例
