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.token的transfer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testnetyy111的active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
调用eosio合约的
buyram方法传入购买者账户名称和接收者账户名称
购买价值
