Python：从RestAPI下载zip文件

Question

第三方RestAPI提供了服务器日志文件，此刻我们正在使用curl命令下载日志文件，例如curl -H "X-Auth-Token: XXXXXXXXXXXXXXXXXXXXXXXXXX" https://host_address/api/v3.0/admin/logs -o logs.zip但是我正在尝试使用Flask / Python创建简单的仪表板，这是我的路线的Python / Flask代码：@app.route('/download/server/logs')def download_log():    import requests    from flask import send_file    res = requests.get('http://<rest_api_host>/v1.2/admin/logs', stream=True)    return send_file(        res.content,        attachment_filename='console_log.zip',        mimetype='application/zip'    )但是，当我从浏览器中访问该网址时，出现以下错误，Traceback (most recent call last):.........  File "/Users/admin/Documents/project/__init__.py", line 940, in download_console_logs    res.content,  File "/Users/admin/Documents/project/venv3/lib/python3.6/site-packages/requests/models.py", line 823, in content    self._content = bytes().join(self.iter_content(CONTENT_CHUNK_SIZE)) or bytes()  File "/Users/admin/Documents/project/venv3/lib/python3.6/site-packages/requests/models.py", line 745, in generate    for chunk in self.raw.stream(chunk_size, decode_content=True):  File "/Users/admin/Documents/project/venv3/lib/python3.6/site-packages/urllib3/response.py", line 436, in stream    data = self.read(amt=amt, decode_content=decode_content)  File "/Users/admin/Documents/project/venv3/lib/python3.6/site-packages/urllib3/response.py", line 384, in read    data = self._fp.read(amt)  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 449, in read    n = self.readinto(b)  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 497, in readinto    self._close_conn()  File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/http/client.py", line 403, in _close_conn    fp.close()AttributeError: 'NoneType' object has no attribute 'close'我使用PyCharm放置了断点/调试器，并能够看到其中res.content包含二进制数据，但是我无法弄清楚这里出了什么问题。这是简单的图表，解释了我要做什么，

我采用了以下方法，它以非常有效的方式解决了我的问题。

@app.route('/download/server/logs')

def download_log():

    import requests

    from flask import Reponse

    res = requests.get('http://<rest_api_host>/v1.2/admin/logs', stream=True)

    return Response(

        res.iter_content(chunk_size=1024),

        direct_passthrough=True

    )
