使用 Ruby 连接到 Coinbase API 并遇到连接问题。法拉第

尝试使用 Ruby 连接到 Coinbase GDAX 沙箱 API。目前使用 Faraday，但欢迎 HTTParty 或 Ruby Core API 建议。

我很难提出帖子请求，似乎无法说出我在哪里搞砸了。

出现了一系列错误，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 block in initialize_http_header': undefined methodstrip' for 1556021965:Fixnum (NoMethodError)

Coinbase 文档：https ://docs.pro.coinbase.com/ ? ruby#signing-a-message

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
