使用Ruby连接到Coinbase API并遇到连接问题。法拉第

Question

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

我很难做出帖子请求，似乎无法告诉我在哪里搞砸了。

出现错误的清单，但最重要的是：

/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）

简而言之，我的api电话。

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

foo.new.post_buy

您可以在http/header.rb上检查代码：它在每个标头上调用strip，因此每个标头值都应该是一个字符串。

我认为这是违规行，你在这里提供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修复它：

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