使用https時未定義字符串'each'

在我的應用程序暫存環境中，當我嘗試通過https訪問頁面時，出現錯誤，網頁正確使用http。我得到的錯誤是：使用https時未定義字符串'each'

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

它失敗是在上線日創業板架的地方：

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

看來，他不能處理通過的身體。我檢查了body，它是一個包含我的頁面所有html代碼的字符串。該參數的數據類型應該是一個數組。

有人有一個想法，爲什麼請求失敗，身體沒有包含和它需要的數組？在這裏你可以看到我的traceroute，但是我不清楚是什麼導致了這個問題，因爲我沒有在其中看到我的應用程序的任何痕跡，也沒有向我的應用程序傳遞任何此功能。

另請參閱我的問題我打開機架寶石，但它似乎不是一個問題。 https://github.com/rack/rack/issues/548

SOLUTION：

發生這種情況，因爲這是恢復身體作爲一個字符串的自定義中間件的，我在一個數組這個包裹身體和問題得到解決！謝謝您的幫助！

它看起來像你的應用程序，或者是一塊您的應用程序和'機架:: Etag'之間的中間件，返回一個字符串作爲響應主體，而不是對「每個」作出響應的東西。你有沒有添加任何中間件？（在Ruby 1.8和更早的版本中，返回一個字符串作爲響應體，但在Ruby 1.9中''''''''''''''''''''''。 – matt 2013-04-23 18:52:19

@matt謝謝！我確實使用了一箇中間件來重寫我的s3資產的路徑，似乎它是爲Ruby 1.8編寫的！非常感謝！ – SteenhouwerD 2013-04-23 19:17:37

你說：

我檢查身體，它是在它我的網頁的所有HTML代碼的字符串。該參數的數據類型應該是一個數組。

body參數來自哪裏？你期望這個數組的元素是什麼？看起來這可能是你想要什麼：

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

這是包括這個的機架寶石，而不是我。我編輯寶石，並將body.inspect放入其中，並看到它是一個字符串。通常它應該是一個有很多東西的數組（標題，...）。就像我在文章中提到的那樣，我不會將其明確地稱爲「明確的」，它被深深地稱爲軌跡，我認爲它無法找到導致此問題的原因。 – SteenhouwerD 2013-04-23 18:33:12

使用https時未定義字符串'each'
