Question

有人可以解释我在这里做错了吗？我试图避免在方法内键入并重新声明帐户的所有变量。

#https://github.com/nukeproof/oanda_api
require 'oanda_api'
#require 'rsruby'
require 'indicators'

def createOrder(instrument="EUR_USD",type="market",units)
    order = $client.$account($acct_id).order(instrument: "EUR_USD",type: "market",side: type,units: units).create
    puts "time: "+order.time+"\nprice: "+order.price+"\nid: "+order.trade_opened.id
    return(order.trade_opened.id)
end

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE #bad practice...anyone who copies this code dont do this!
$acct_id=123456
$acct_token="abcd"

$client = OandaAPI::Client::TokenClient.new(:practice, $acct_token)
$account = client.account($acct_id).get

createOrder(units:1000)

错误

        order = $client.$account($acct_id).order(instrument: ...

Answer 1

这部分代码无效

$client.$account(...)

如果您编写$client.，那么Ruby希望看到的下一件事是方法的名称，方法名称不能以$开头，因此$account无效。尝试从$account那里删除美元符号。

将方法的结果作为全局值传递
