在上一课中，我们介绍了如何在OceanOne交易比特币。OceanOne支持交易任何Mixin Network上的token，包括所有的ERC20和EOS token，不需要任何手续和费用，直接挂单即可。下面介绍如何将将一个ERC20 token挂上OceanOne交易！在掌握了ERC20 token之后，就可以把任何token在Ocean上买卖。
此处我们用一个叫做Benz的ERC20 token为例。这个token已经被充值进Mixin Network，你可以在区块链浏览器看到这个token在Mixin Network内部的总数和交易
预备知识:
先将Benz币存入你的钱包，然后使用getAssets API读取它的UUID.
取得该币的UUID
调用 getAssets API 会返回json数据, 如:
- asset_id 币的UUID.
- public_key 该币的当前钱包的地址.
- symbol 币的名称. 如: Benz.
if cmd == "aw"
assetsInfo = walletAccount.read_assets()
p "--------The Wallet Assets List-----------------"
assetsInfo["data"].each { |x| puts x["symbol"] + " " +
x["balance"] + " " + x["public_key"] +
x["account_name"] + " " + x["account_tag"]}
p "----------End of Wallet Assets --------------"
end调用 read_assets API的完整输出如下:
"--------The Wallet Assets List-----------------"

-------------------------------------------------------------------------限价挂单
- 挂限价买单 低于或者等于市场价的单.
- 挂限价卖单 高于或者是等于市场价的单.
OceanOne支持三种基类价格: USDT, XIN, BTC, 即: Benz/USDT, Benz/XIN, Benz/BTC, 这儿示范Benz/USDT.
限价挂卖单.
新币挂单后,需要等一分钟左右，等OceanOne来初始化新币的相关数据.
if ocmd == "s3"
p "Input the price of ERC/USDT: "
bprice = gets.chomp
p "Input the amount of ERC20_BENZ: "
amount = gets.chomp
memo = Utils.GenerateOceanMemo(USDT_ASSET_ID,"A",bprice)
p memo
assetsInfo = walletAccount.read_asset(ERC20_BENZ)
if assetsInfo["data"]["balance"].to_f > 0 && assetsInfo["data"]["balance"].to_f >= amount.to_f
transInfo = walletAccount.create_transfer(walletAccount.encrypt_pin(DEFAULT_PIN),
{
asset_id: ERC20_BENZ,
opponent_id: OCEANONE_BOT,
amount: amount,
trace_id: SecureRandom.uuid,
memo: memo
})
p transInfo
p "The Order id is " + transInfo["data"]["trace_id"] + " It's needed by cancel-order!"
else
p "Not enough ERC20_BENZ"
end
end限价挂买单.

p "Input the amount of USDT: "

})
p transInfo
p "The Order id is " + transInfo["data"]["trace_id"] + " It's needed by cancel-order!"
else
p "Not enough USDT"
end
end读取币的价格列表
读取币的价格列表，来确认挂单是否成功!
if ocmd == "3"
Utils.OceanOneMarketPriceRequest(ERC20_BENZ, USDT_ASSET_ID)
end
def self.OceanOneMarketPriceRequest(asset_id, base_asset_id)
full_url = "https://events.ocean.one/markets/" + asset_id + "-" + base_asset_id + "/book"
data = HTTP.get(full_url).body
body = ""
redData = data.readpartial
while redData != nil
body = body + redData
redData = data.readpartial
end
result = ActiveSupport::JSON.decode(body).with_indifferent_access
result["data"]["data"]["asks"].each { |x|
puts x["side"] + " " + x["price"] + " " +
x["amount"] + " " + x["funds"]
}
result["data"]["data"]["bids"].each { |x|
puts x["side"] + " " + x["price"] + " " +
x["amount"] + " " + x["funds"]
}
