EOS开发(十一)使用RPC API购买/出售内存

1. 前言

前面的文章陆续提到过EOS中的三种资源:内存、CPU和NET。一个账户如果要进行某些操作,例如转账,必须要有足够的资源,才能进行操作。

这篇文章对内存资源进行一个大概的讲解,并通过实例演示如何通过RPC API,操作内存的购买/出售。

我们依然在测试网络http://jungle.cryptolions.io:18888上,使用Postman对API进行测试。

2. 内存

内存资源是通过使用EOS Token购买获得的,可以由其他账户为你购买,也可以自己购买。不管是前面哪种形式为你购买的内存,都是属于你的,可以出售,获得的EOS Token也都会立刻打入到你的账户。

本质上,购买和出售内存,都是通过eosio.tokentransfer方法,与系统账户eosio.ram相互转账。同时,系统会在每次交易中(包括购买和出售)收取本次交易中EOS总额的5%作为手续费,也就是向eosio.ramfee转账。需要注意的是,内存资源是不可自动恢复的。

3. 购买内存

这里演示的是为自己购买内存。如果需要为他人购买内存,只需要将接收者改为他人的账户

购买内存是可以根据单位调用不同的方法:按bytes购买的buyrambytes和按EOS购买的buyram。我们这里使用buyram

3.1 查看账户内存总量

我们将使用账户testnetyy111为自己购买内存,先查看该账户的内存及EOS情况:

显示内存总量为1919695bytes

3.2 准备钱包和钱包服务

打开钱包服务keosd,这里我们指定其服务IP为8899

yuyangdeMacBook-Pro:keosd yuyang$ keosd --http-server-address=localhost:8899

通过调用钱包的RPC API,我们打开并解锁钱包,保证钱包中有testnetyy111active权限的公私钥。这部分不明白可以先看前面的文章

3.3 生成购买内存的bin字符串

  1. 调用eosio合约的buyram方法

  2. 传入购买者账户名称和接收者账户名称

  3. 购买价值100EOS的内存

api
http://jungle.cryptolions.io:18888/v1/chain/abi_json_to_bin

params
{
   "code": "eosio",
   "action": "buyram",
   "args": {

        "receiver": "testnetyy111",
        "quant": "100.0000 EOS",
    }
 }

return
