前面一篇《EOS簡介與環(huán)境搭建》對EOS作了簡單介紹和環(huán)境搭建，并沒有涉及到編譯和部署智能合約。EOS的智能合約是基于C++語言的，感覺門檻稍微有點高吧拯田。不過，本篇還沒有涉及到EOS智能合約的編寫甩十。
本篇的主要目的是記錄下學(xué)習(xí)的過程船庇，避免大家少走彎路少采坑。還有好多不懂的地方侣监，可能會有些描述不當(dāng)?shù)牡胤窖悸郑€請大家多指正。話不多說橄霉，開始帶領(lǐng)大家來一場EOS的開發(fā)入門體驗张弛。
EOS版本說明
EOS的版本特別多，可謂五花八門酪劫，可能會遇到各種坑吞鸭。
EOS官方版本列表
就在今天（6月2日）早上，EOSIO發(fā)布了1.0版本覆糟，對Dawn 4.2做了一些小改動刻剥。該版本加入了一個可選擇的P2P網(wǎng)絡(luò)協(xié)議，能夠支持多線程網(wǎng)絡(luò)傳輸以及更快的同步滩字。
就拿EOS的博客來說造虏，網(wǎng)上的博客有些是直接從官方文檔翻譯過來的御吞，自己可能都沒有試驗過。有些博客上文不接下文漓藕，命令格式都有問題陶珠，或者中途跳過了某些操作，可能到了哪一步都執(zhí)行不了享钞。
比如很多博客講EOS提供的currency智能合約部署揍诽，但是這個currency智能合約在2018年5月11號發(fā)布的DAWN 4.0版本就移除了。于是栗竖，如果Git下載的是最新的EOS源碼暑脆，部署currency合約的時候就會出錯。當(dāng)然狐肢，也可以下載指定的版本來編譯學(xué)習(xí)添吗。
本文是在最新版本上實驗的，這個也是遇到了部署currency合約的坑才發(fā)現(xiàn)的份名〉可以跳轉(zhuǎn)"2、部署B(yǎng)IOS合約"的一節(jié)查看僵腺，發(fā)現(xiàn)里面的"contracts"文件夾沒有"currency"合約鲤孵。
錢包的使用
1、創(chuàng)建錢包
進(jìn)入到"cleos"組件的根目錄想邦，然后執(zhí)行"./cleos wallet create"命令
wenzildeiMac:cleos wenzil$ ./cleos wallet create
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5JiXgmkmpT62QEv8aqX56pG8WT2daXnDM21wzmMKfdHQfbT2eKw"
"PW5JiXgmkmpT62QEv8aqX56pG8WT2daXnDM21wzmMKfdHQfbT2eKw"是隨機(jī)生成的錢包私鑰裤纹，需要記錄下來并保存好委刘。
2丧没、部署B(yǎng)ios合約
EOS自帶了很多智能合約，目錄位于"eos/contracts"目錄下锡移，eosio.bios是其中一個呕童。
確保EOS的區(qū)塊鏈節(jié)點組件nodeos在運行狀態(tài)，否則會提示如下內(nèi)容：
wenzildeiMac:cleos wenzil$ ./cleos set contract eosio ../../contracts/eosio.bios -p eosio
Reading WAST/WASM from ../../contracts/eosio.bios/eosio.bios.wasm...
Using already assembled WASM...

Failed to connect to nodeos at http://localhost:8888/; is nodeos running?
成功的運行結(jié)果：
wenzildeiMac:cleos wenzil$ ./cleos set contract eosio ../../contracts/eosio.bios -p eosio

3淆珊、創(chuàng)建一組密鑰
wenzildeiMac:cleos wenzil$ ./cleos create key
Private key: 5K55ERTgLcR9RK5K7fagwJaHXCvnZJy5cMHh6xmNgLUXvneTTzr
Public key: EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat
4夺饲、導(dǎo)入私鑰到錢包
命令格式為：
./cleos wallet import [private_key]
private_key：為上一步生成的私鑰
操作如下：
wenzildeiMac:cleos wenzil$ ./cleos wallet import 5K55ERTgLcR9RK5K7fagwJaHXCvnZJy5cMHh6xmNgLUXvneTTzr
imported private key for: EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat
賬戶的使用
5、創(chuàng)建用戶賬戶
使用導(dǎo)入私鑰到錢包生成的密鑰來創(chuàng)建用戶賬戶施符，以下演示創(chuàng)建兩個賬戶user1和user2
命令格式為：
./cleos create account eosio [account_name] [owner_key] [active_key]
cleos create 命令需要兩個秘鑰往声，為了方便，這里給它兩個相同的秘鑰戳吝，都是上面生成的私鑰浩销。
account_name：為要創(chuàng)建的賬戶名
owner_key：作用是掌握該賬戶所有控制權(quán)限
active_key：作用是只掌握該賬戶資金訪問權(quán)限
操作如下：
wenzildeiMac:cleos wenzil$ ./cleos create account eosio user1 EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat

wenzildeiMac:cleos wenzil$ ./cleos create account eosio user2 EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat

warning: transaction executed locally, but may not be confirmed by the network yet
6、查看對應(yīng)的賬戶信息
命令格式為：
./cleos get account [account_name]
操作如下：
wenzildeiMac:cleos wenzil$ ./cleos get account user1
privileged: false
permissions:
owner 1: 1 EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat
active 1: 1 EOS6Ps9FM3A6yi5JgVZ7hPzQU4gAgQCgZ2mqra9EoP6JLTi51zzat
memory:
quota: -1 bytes used: 2.66 Kb
net bandwidth: (averaged over 3 days)
used: -1 bytes
available: -1 bytes
limit: -1 bytes
cpu bandwidth: (averaged over 3 days)
used: -1 us
available: -1 us
limit: -1 us
部署和調(diào)用智能合約
7听哭、部署Token合約
命令格式為：
./cleos set contract [account_name] ../../contracts/eosio.token -p [account_name]
[account_name]是要部署的賬戶慢洋，這里替換為"user1"塘雳。
wenzildeiMac:cleos wenzil$ ./cleos set contract user1 ../../contracts/eosio.token -p user1
Reading WAST/WASM from ../../contracts/eosio.token/eosio.token.wasm...
Using already assembled WASM...
Publishing contract...

# eosio <= eosio::setcode {"account":"user1","vmtype":0,"vmversion":0,"code":"0061736d01000000017e1560037f7e7f0060057f7e7e7f7f...

warning: transaction executed locally, but may not be confirmed by the network yet
8、調(diào)用Token合約的create函數(shù)
命令為：
./cleos push action user1 create '{"issuer":"eosio", "maximum_supply":"1000000000.0000 EOS", "can_freeze":0, "can_recall":0, "can_whitelist":0}' -p user1
創(chuàng)建一個名稱為"EOS"的Token（代幣）普筹，總發(fā)行量為10億败明。
wenzildeiMac:cleos wenzil$ ./cleos push action user1 create '{"issuer":"eosio", "maximum_supply":"1000000000.0000 EOS", "can_freeze":0, "can_recall":0, "can_whitelist":0}' -p user1
executed transaction: feef0adec95643f059085f813491b884d2058d7c987e02678ef359524e887e6c 120 bytes 378 us
# user1 <= user1::create {"issuer":"eosio","maximum_supply":"1000000000.0000 EOS"}
warning: transaction executed locally, but may not be confirmed by the network yet
9、發(fā)行代幣
命令為：
./cleos push action user1 issue '["user1", "100.0000 EOS","memo"]' -p eosio
給用戶user1發(fā)100個EOS幣太防，留言是"memo"
wenzildeiMac:cleos wenzil$ ./cleos push action user1 issue '["user1", "100.0000 EOS","memo"]' -p eosio
executed transaction: a1dcff4887555bd037ffad0d2877193ed2f56195b07c5ac220fd13c5846e54d6 128 bytes 33617 us
# user1 <= user1::issue {"to":"user1","quantity":"100.0000 EOS","memo":"memo"}
# user1 <= user1::transfer {"from":"eosio","to":"user1","quantity":"100.0000 EOS","memo":"memo"}
# eosio <= user1::transfer {"from":"eosio","to":"user1","quantity":"100.0000 EOS","memo":"memo"}
warning: transaction executed locally, but may not be confirmed by the network yet
現(xiàn)在user1有100個EOS幣了妻顶。
10、如果出現(xiàn)了如下情況杏头，需要對錢包進(jìn)行解鎖盈包。
Error 3120003: Locked wallet
Ensure that your wallet is unlocked before using it!
Error Details:
You don't have any unlocked wallet!
執(zhí)行如下命令，然后輸入錢包的私鑰醇王，也就是創(chuàng)建錢包時返回的私鑰呢燥。
wenzildeiMac:cleos wenzil$ ./cleos wallet unlock
password:
11、轉(zhuǎn)賬交易
命令為：
./cleos push action user1 transfer '["user1", "user2", "20.0000 EOS", "哥送你20個EOS幣"]' -p user1
通過user1向user2轉(zhuǎn)20個ESO幣
wenzildeiMac:cleos wenzil$ ./cleos push action user1 transfer '["user1", "user2", "20.0000 EOS", "哥送你20個EOS幣"]' -p user1
executed transaction: 4ab89c1618eb90c8a3fd56d6182f13510b9e5ac50f09fe8a61b96ae88346bf51 152 bytes 677 us
# user1 <= user1::transfer {"from":"user1","to":"user2","quantity":"20.0000 EOS","memo":"哥送你20個EOS幣"}
# user2 <= user1::transfer {"from":"user1","to":"user2","quantity":"20.0000 EOS","memo":"哥送你20個EOS幣"}
warning: transaction executed locally, but may not be confirmed by the network yet
12寓娩、查看賬戶信息
wenzildeiMac:cleos wenzil$ ./cleos get table user1 user1 accounts
{
"rows": [{
"balance": "80.0000 EOS"
}
],
"more": false
}
wenzildeiMac:cleos wenzil$ ./cleos get table user1 user2 accounts
{
"rows": [{
"balance": "20.0000 EOS"
}
],
"more": false
}
現(xiàn)在user1有80個EOS代幣叛氨，user2有20個EOS代幣。
