【问题描述】：

我的帖子似乎到达了主机，但是它的格式可能不正确？不以 JSON 格式输入？

主持人的结果是给我一个错误代码：invalid_request 消息：请求验证失败。

主机文档：

这意味着自动订购没有足够的信息来下订单。这几乎总是发生，因为你没有完全在您的自动订购中填写您的亚马逊账户信息部分。

我的错误结果包括以下内容：

【问题讨论】：

你为什么要在你的视图中进行 API 调用？那是你应该进行 API 调用的最后一个地方。
你想在这里做什么？
@ThomasRoss 和 Max 我正在尝试使用上述主体调用“api.zinc.io/v0/order”API。我可以在 Python 中做到这一点，但现在正试图让它在 Ruby 上运行。我现在把它作为一种方法放在控制器中。但是，我在调用该方法时仍然收到上述错误。非常感谢您看一看，我一直在努力解决这个问题。

【解决方案1】：

根据Zinc Docs，您应该在正文中发送 json 对象，但您正在发送 json 数组。要发送 JSON 对象，您应该以花括号“{}”而不是方括号“[]”开始您的正文

@ZincResult=HTTParty.post(zincUrl,
    :body => {.........}.to_json,
    :headers => { 'Content-Type' => 'application/json' } )
