我正在尝试使用python3和requests从FEMA下载zip文件。当我将URL粘贴到浏览器中以及wget时，URL也会起作用。有一个重定向，我看到它已使用requests成功重定向。但是，返回的内容比我期望的字节少得多，例如格式错误的zip。
以下是网址和代码段：
>>> import requests
>>> url = 'https://hazards.fema.gov/femaportal/NFHL/Download/ProductsDownLoadServlet?DFIRMID=10001C&state=DELAWARE&county=KENT COUNTY&fileName=10001C_20190130.zip'
>>> resp = requests.get(url)
>>> len(resp.content)
2583
>>> resp.headers['content-length']
'66892906'
>>> resp.url
'https://hazards.fema.gov/nfhlv2/output/County/10001C_20190130.zip'
更新：我正在docker容器中运行它。在容器外部，它按预期工作。
