使用Ruby连接到Coinbase API并遇到连接问题。法拉第

正在尝试使用Ruby连接到Coinbase GDAX沙盒API。 目前正在使用法拉第，但欢迎HTTParty或rubycoreapi建议

我很难提出发帖请求，似乎不知道我把事情搞砸了

出现错误的详细列表，但最上面的是：

/System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/Ruby/2.3.0/net/http/header.rb:18:in 初始化\u http\u头中的

块：未定义的方法
1556021965:Fixnum（命名错误）

Coinbase文档：

简而言之，我的api调用

payload = { 
            "data": "DATA"        
        }

        url = 'https://api-public.sandbox.gdax.com/orders'
        conn = Faraday.new      
        response = conn.post do |req|           
            req.url url
            req.headers['REQ-HEADER-1'] = "FOO",
            req.headers['REQ-HEADER-1'] = "BAR",           
            req.body = payload      
        end

        puts response

    def post_buy

        usd = get_usd_available         
        usd = usd / 2

foo.new.post_buy

您可以在以下位置检查代码：它在每个标题上调用
strip
，因此每个标题值都应该是字符串

我认为这是有问题的一行，您在这里提供了一个整数作为标题值：

req.headers['CB-ACCESS-TIMESTAMP'] = Time.now.to_i

将其转换为字符串应该可以修复它：

req.headers['CB-ACCESS-TIMESTAMP'] = Time.now.to_i.to_s

您是否尝试过将时间戳转换为字符串？并发出请求当我尝试将其转换为字符串时，我得到此响应
{“message”=>“User-Agent头是必需的。”}
