在我的应用程序暂存环境中，当我尝试通过 https 访问页面时出现错误，该网页可以正确使用 http。我得到的错误是：

 undefined method `each' for #<String:0x00000009371f28>

失败的地方在线上的宝石架上：

body.each { |part| parts << part }

在

def digest_body(body)
    parts = []
    body.each { |part| parts << part }
    string_body = parts.join
    digest = Digest::MD5.hexdigest(string_body) unless string_body.empty?
    [digest, parts]
end

看来，他无法处理通过的身体。我检查了正文，它是一个字符串，其中包含我页面的所有 html 代码。这个参数的数据类型应该是一个数组。

有人知道为什么请求失败并且正文没有像它需要的那样包含和数组？在这里您可以看到我的跟踪路由，我不清楚是什么导致了问题，因为我没有在其中看到我的应用程序的任何痕迹，并且我没有从我的应用程序向该函数传递任何内容。

另请参阅我在 rack gem 上打开的问题，但这似乎不是他们的问题。https://github.com/rack/rack/issues/548

解决方案：

发生这种情况是因为自定义中间件将主体作为字符串返回，我将这个主体包装在一个数组中，问题就解决了！谢谢您的帮助！

你说：

我检查了正文，它是一个字符串，其中包含我页面的所有 html 代码。这个参数的数据类型应该是一个数组。

body参数从哪里来？你期望这个数组的元素是什么？看起来这可能是您想要的：

def digest_body(body)
    parts = body.split("\n")
    string_body = parts.join
    digest = Digest::MD5.hexdigest(string_body) unless string_body.empty?
    [digest, parts]
end
