金字塔請求：UnicodeDecodeError

我正在與金字塔框架，試圖向其發佈UTF8數據。這裏是我得到的例外。我不知道如何解決這個問題。任何想法爲什麼它發生？金字塔請求：UnicodeDecodeError

我從具有這些屬性定義的HTML表單提交的數據：

<form name="form_reg" id="formtrans" method="post" action="signup" 
     content="text/html; charset=utf-8">

你想要發佈什麼？表單編碼數據中的某些內容是* not * UTF-8。你的'rpc_adduser'嘗試訪問'request.params' multidict結構，觸發表單數據的解碼並且解碼失敗。 –

我正在發佈一個HTML表單。具有該格式的HTML文件的字符集是UTF-8 – KennyPowers

您是否檢查過'request.body'？包含原始POST。 –

玉傢伙，看來我已經找到了問題。問題是表單是基於PHP的服務器。它使用cURL將數據從一臺服務器發佈到另一臺服務器。第二臺服務器有Pyramid應用程序，它接受請求。我加入的iconv（ 'ISO-8859-1'， 'UTF-8'，$ fields_string），這讓它固定

  $fields = $_REQUEST; 

      foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } 
      rtrim($fields_string,'&');     
      //open connection 
      $ch = curl_init(); 
      curl_setopt($ch, CURLOPT_HTTPHEADER, "Content-Type: text/html; charset=utf-8"); 

      curl_setopt($ch, CURLOPT_URL, $url); 
      curl_setopt($ch, CURLOPT_POST, count($fields)); 
      $fields_string = iconv('ISO-8859-1', 'UTF-8', $fields_string); 
      curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string); 

      $result = curl_exec($ch); 
      curl_close($ch);

我不知道爲什麼PHP是總是這樣，在$ _REQUEST應使用UTF-8作爲頁面的字符集（meta也是utf-8）。雖然我不是PHP的忠實粉絲。謝謝大家的幫助！

因此，您的客戶端不是瀏覽器，而是PHP，而您需要明確地發佈UTF-8，否則它會使用Latin-1。 –

不是PHP，而是捲曲。但是，是的，這是我的錯誤，我沒有意識到數據被張貼在cURL – KennyPowers

哇！這在之前提到會有所幫助。我猜想這是金字塔之外的問題，但我不認爲我們中的任何人都會猜到這是您從未提及的PHP中間人的問題。是的，編碼實際上很難做到，尤其是當你將這麼多技術鏈接在一起時。 –
