FIBOS快速入门

摘要：启动节点环境配置脚本创建文件夹，保存如下代码至运行开发环境运行结果日志部分如果你看到了以上的消息，说明运行成功，已经开始区块生产。

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。

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-1   producer_plugin.cpp:1194      produce_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。

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);

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": ""
    }]
}

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;

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。

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：
