單會話多個發布/獲取python請求

Question

我正在嘗試編寫一個搜尋器以使用python請求模塊自動下載某些文件。 但是，我遇到了一個問題。

我初始化了一個新的請求會話，然后使用post方法登錄網站，之后，只要我嘗試使用post / get方法（下面的簡化代碼）：

s=requests.session()
s.post(url,data=post_data, headers=headers)
#up to here everything is correct, the next step will report error 
s.get(url) or s.post(url) even repeat s.post(url,data=post_data, headers=headers) will report error 

它將報告錯誤，如下所示：

我完全不知道為什么會這樣，有人可以幫助我嗎？

Answer 1

請求使用urllib3的內部版本。 我的印象是，內部urllib3與請求本身之間存在某種形式的不匹配。

httplib_response = conn.getresponse（buffering = True）TypeError：getresponse（）得到了意外的關鍵字參數'buffering'

似乎表明請求正在調用urllib3（內部版本，而不是Python的版本），但希望指定不存在的“緩沖”。

其他問題與我所經歷的相似。

最新的請求版本（2.6。*）還有其他一些問題，這些問題現在正在解決中。 我懷疑您正在使用該版本。 嘗試使用先前的2.4.1甚至2.2.1版本。 如果在程序頂部指定要使用的版本，則可以保留最后安裝的版本：

__requires__ = ["requests==2.2.1"]
import pkg_resources

（至少在導入請求本身之前）

解決方案 ：上周，我與開發團隊交換了幾封郵件，看來他們很快就生成了2.7版本的修復程序！ （實際上，我看到它是昨天才上傳的）。 因此，如果您遇到類似的問題，請下載最新版本！

通過將請求升級到最新版本已解決了該問題，這可能是2.6中的錯誤（也許是此版本，尚不確定）。
