FIBOS快速入门 FIBOS快速入门

搭建一个 FIBOS 开发环境需要安装 fibos 和 fibos.js。
本章节示例代码的目录结构：

hello_fibos/ ├── fibos_client │├── call.js//调用合约接口脚本文件 │├── initClient.js//FIBOS连接文件 │├── deploy.js//加载、发布合约脚本文件 │├── hello ││├── hello.abi//合约abi文件 ││└── hello.js//合约代码文件 │└── package.json └── start_fibos └── node.js

本章节示例代码地址：https://github.com/FIBOSIO/sa... 下basic文件夹示例。
启动节点 【FIBOS快速入门】环境配置脚本
创建 start_fibos 文件夹，保存如下代码至 node.js

var fibos = require('fibos'); fibos.load('chain'); fibos.load('chain_api'); fibos.load('history_api'); fibos.load('producer', { 'producer-name': 'eosio', 'enable-stale-production': true }); fibos.load('http', { 'http-server-address': '0.0.0.0:8888' }); fibos.load('net', { 'p2p-listen-endpoint': '0.0.0.0:9876' }); fibos.config_dir = 'fibos_config_dir/'; fibos.data_dir = 'fibos_data_dir/'; fibos.enableJSContract = true; fibos.start();

运行 FIBOS 开发环境

hello_fibos$ fibos start_fibos/node.js

运行结果日志（部分）：

…… 2018-07-30T03:29:01.004 thread-1producer_plugin.cpp:1194produce_block] Produced block 00000002e091c956... #2 @ 2018-07-30T03:29:01.000 signed by eosio [trxs: 0, lib: 0, confirmed: 0]

如果你看到了以上的消息，说明运行成功，fibos 已经开始区块生产。
JavaScript 合约代码

注意：需新建窗口，保证 node.js 节点正常运行

创建文件夹 fibos_client，保存如下代码至 hello/hello.js：

exports.hi = user => console.error('in contract:', user);

合约 ABI 文件保存如下代码至 hello/hello.abi：

{ "version": "eosio::abi/1.0", "structs": [{ "name": "player", "base": "", "fields": [{ "name": "title", "type": "string" }, { "name": "age", "type": "int64" }] }, { "name": "hi", "base": "", "fields": [{ "name": "user", "type": "name" }] }], "actions": [{ "name": "hi", "type": "hi", "ricardian_contract": "" }] }

连接 FIBOS 节点在文件夹fibos_client下，新建 initClient.js，保存如下代码：

var FIBOS = require('fibos.js'); function initClient(_keyProvider) { return FIBOS({ chainId: 'cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f', keyProvider: _keyProvider, httpEndpoint: 'http://127.0.0.1:8888', logger: { log: null, error: null } }); }module.exports = initClient;

加载、发布合约脚本在文件夹fibos_client下，新建 deploy.js，保存如下代码：

var FIBOS = require('./initClient.js') var fs = require('fs'); var config = { 'public-key': 'FO6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV', 'private-key': '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3', 'contractName': 'hello' }; // new FIBOS client var fibos = FIBOS(config['private-key']); // create account hello fibos.newaccountSync({ creator: 'eosio', name: 'hello', owner: config['public-key'], active: config['public-key'] }); //setcode var js_code = fs.readTextFile('./hello/hello.js'); fibos.setcodeSync(config['contractName'], 0, 0, fibos.compileCode(js_code)); //getcode var code = fibos.getCodeSync(config['contractName'], true); console.log('code:', code); //setabi var abi = JSON.parse(fs.readTextFile('./hello/hello.abi')); fibos.setabiSync(config['contractName'], abi);

运行脚本：

hello_fibos$ fibos fibos_client/deploy.js

输出结果（部分）：

code: { "account_name": "hello", "code_hash": "383a12daacaf124eea9afc529822d990853b5b99570401b8394534b746ea3977", "wast": "", "wasm": "504b03042d00000008002cadfe4c6a9400a2360000003900000008001400696e6465782e6a7301001000000000000000000000000000000000004bad28c82f2a29d6cbc854b055282d4e2d52b0b55348cecf2bcecf49d54b2d2aca2fd250cfcc0389941425269758a9eb8055695a0300504b010200001400000008002cadfe4c6a9400a23600000039000000080000000000000001000000000000000000696e6465782e6a73504b0506000000000100010036000000700000000000" }

备注：wasm 是一个低层级的、轻便式的字节码,它致力于实现接近原生的执行速度。
调用合约使用 fibos.js 中的 API 去调用合约。
在文件夹fibos_client下，新建 call.js，保存如下代码：

var FIBOS = require('./initClient.js') var config = { 'public-key': 'FO6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV', 'private-key': '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3', 'contractName': 'hello' }; // new FIBOS client var fibos = FIBOS(config['private-key']); //call abi var ctx = fibos.contractSync(config['contractName']); let i = ctx.hiSync('hello', { authorization: config['contractName'] }); console.log(i)

执行脚本：

hello_fibos$ fibos fibos_client/call.js

控制台打印结果如下：
