瓶破裂的水管AJAX調用

後重定向時，我有一個JQuery的AJAX調用：瓶破裂的水管AJAX調用

$.getJSON($SCRIPT_ROOT + '/_click_btn?btnId='+$(this).attr("id"), 
      $('form').serialize(), 
      function(data) { 
      // return to send_messages page 
      window.location = 'send_messages'; 
});

它沒有做任何幻想。它只是將一些表單數據保存到數據庫中（使用SQLAlchemy）。我在window.location語句中放置了一個斷點，如果我將重定向延遲了1-2秒，那麼斷開的管道就不會發生。處理這個問題的最佳做法是什麼？

另一個需要注意的事項是在AJAX調用完成後DB會話保持打開狀態。

錯誤消息如下。

請問您可以粘貼錯誤日誌的其餘部分嗎？ – dvnguyen

完成！謝謝！！！ – user800133

作爲臨時解決方案，我在重定向之前添加了500毫秒的延遲。看起來好像有一個更好的方法，但現在這個工作。

我看到這個錯誤太Ubuntu的泊塢容器上Kubernetes在Ubuntu VM：

Error on request: 
Traceback (most recent call last): 
    File "/usr/local/lib/python2.7/dist-packages/werkzeug/serving.py", line 270, in run_wsgi 
    execute(self.server.app) 
    File "/usr/local/lib/python2.7/dist-packages/werkzeug/serving.py", line 261, in execute 
    write(data) 
    File "/usr/local/lib/python2.7/dist-packages/werkzeug/serving.py", line 227, in write 
    self.send_header(key, value) 
    File "/usr/lib/python2.7/BaseHTTPServer.py", line 412, in send_header 
    self.wfile.write("%s: %s\r\n" % (keyword, value)) 
IOError: [Errno 32] Broken pipe

我創建了一個全新的Ubuntu xenial VM跑在Kubernetes Ubuntu的碼頭工人容器相同的代碼，而這個錯誤是不是看到和Python Flask按預期工作。我認爲這是我的主機（Ubuntu VM）的問題。
