Python的請求不能流UTF-8編碼的文件

我試圖利用HTTP流的Unicode字符的文件，但我發現了一個UnicodeEncodeError：Python的請求不能流UTF-8編碼的文件

>>> requests.put(my_url, headers=my_headers, data=open('test.csv', 'r', encoding='utf-8')) 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module>

    self._send_request(method, url, body, headers) 
    File ".../python3.5/http/client.py", line 1152, in _send_request 
    self.endheaders(body) 
    File ".../python3.5/http/client.py", line 1103, in endheaders 
    self._send_output(message_body) 
    File ".../python3.5/http/client.py", line 936, in _send_output 
    self.send(message_body) 
    File ".../python3.5/http/client.py", line 904, in send 
    datablock = datablock.encode("iso-8859-1") 
UnicodeEncodeError: 'latin-1' codec can't encode character '\u2122' in position 6375: ordinal not in range(256)

我得到的錯誤不管我是否包括encoding='utf-8'。我如何以不需要將整個文件加載到內存中但仍能解決unicode編碼問題的方式發送此文件？

至少在我的情況下，所有我需要做的就是以二進制方式打開文件：

>>> requests.put(my_url, headers=my_headers, data=open('test.csv', 'rb'))

通過以二進制模式打開文件，python沒有嘗試對文件進行編碼，而是直接將其傳遞給url。

open(..., encoding="utf-8")不編碼文件內容完全相反 - 用它你告訴open()到您的文件內容進行解碼成正unicode字符串，不能被無損編碼成請求所需latin-1（是的，HTTP像那樣古老）如果它有'特殊'字符。您需要在發送內容之前編碼您的內容。試着用：

requests.put(my_url, headers=my_headers, data=open("test.csv", "r", encoding="utf-8").read().encode("utf-8"))

芹苴，這是一個非常糟糕的形式來處理文件內容...
