我得到 BrokenPipeError: [Errno 32] Broken pipe 錯誤 python

Question

對於我的代碼部分，您可以在下面找到，有時我會在標題中看到錯誤。 它可能與大量數據或互聯網連接不良有關嗎？ 我嘗試使用 gspread 從一個谷歌電子表格到另一個電子表格中獲取 14k 行。

有什么辦法可以防止這種情況發生嗎？ 將不勝感激任何幫助。

worksheet1.values_clear("tc id!A:B")

source_tc= client.open('tc_sheet')

source_tc.sheet1.delete_row(1)

new_values_tc = source_tc.values_get('Sheet1!A:B')


worksheet1.values_update(
    "tc id!A:B"
    ,
    params={
        'valueInputOption': 'USER_ENTERED'
    } ,
    body={
        'values': new_values_tc['values']
    }
)

您遇到的問題BrokenPipeError可以在官方 Python 文檔中找到（請參閱此處）。 它通常在連接被切斷時拋出，要么是因為它的另一端故意這樣做，要么是因為連接不穩定。 如果您想避免出現此錯誤，您可以處理異常並在發生時重試。 您的代碼修改如下所示：

from requests.exceptions import ConnectionError

def retry_on_connectionerror(f, max_retries=5):
  retries = 0
  while retries < max_retries:
    try:
      return f()
    except ConnectionError:
      retries += 1
  raise Exception("Maximum retries exceeded")


worksheet1.values_clear("tc id!A:B")

source_tc= client.open('tc_sheet')

source_tc.sheet1.delete_row(1)

new_values_tc = source_tc.values_get('Sheet1!A:B')

def update_values():
  worksheet1.values_update(
      "tc id!A:B"
      ,
      params={
          'valueInputOption': 'USER_ENTERED'
      } ,
      body={
          'values': new_values_tc['values']
      }
  )

retry_on_connectionerror(update_values)

修改點如下：

• 導入ConnectionError以便在執行 function 時捕獲它。
• 創建retry_on_connectionerror() function。 它需要一個 function 作為參數，並且可以選擇它應該發出的最大重試次數（默認為 5）。 它執行 function 的次數與max_retries一樣多，直到它工作或超過此數量。
• 將 values_update function 包裝在另一個 function 或closure中。 這允許我們將此代碼傳遞給新創建的retry_on_connectionerror() function。
• 調用retry_on_connectionerror(update_values)以應用上述行為。
