无法用Python-Sentinel卫星数据解压缩下载的文件

Question

我拉不开一个拉链。从哥白尼开放存取中心下载的zip文件。我检索文件并尝试使用以下Python脚本解压缩它：

from sentinelsat.sentinel import SentinelAPI
import zipfile

user = 's5pguest' 
password = 's5pguest' 

api = SentinelAPI(user, password, 'https://s5phub.copernicus.eu/dhus')

api.download("cb078cce-ed6e-46a7-a614-e13830b2a74a")

# The file is succesfully downloaded

zip_ref = zipfile.ZipFile("S5P_NRTI_L2__CO_____20191001T123303_20191001T123803_10188_01_010302_20191001T131513.zip", 'r')
zip_ref.extractall()
zip_ref.close()

文件成功下载，但当它试图解压缩我得到：

BadZipFile                                Traceback (most recent call last)
<ipython-input-3-45c213a35459> in <module>
      9 api.download("cb078cce-ed6e-46a7-a614-e13830b2a74a")
     10 
---> 11 zip_ref = zipfile.ZipFile("S5P_NRTI_L2__CO_____20191001T123303_20191001T123803_10188_01_010302_20191001T131513.zip", 'r')
     12 zip_ref.extractall()
     13 zip_ref.close()

~/anaconda3/lib/python3.6/zipfile.py in __init__(self, file, mode, compression, allowZip64)
   1129         try:
   1130             if mode == 'r':
-> 1131                 self._RealGetContents()
   1132             elif mode in ('w', 'x'):
   1133                 # set the modified flag so central directory gets written

~/anaconda3/lib/python3.6/zipfile.py in _RealGetContents(self)
   1196             raise BadZipFile("File is not a zip file")
   1197         if not endrec:
-> 1198             raise BadZipFile("File is not a zip file")
   1199         if self.debug > 1:
   1200             print(endrec)

BadZipFile: File is not a zip file

如果我尝试使用unzip从终端解压缩此文件，我会得到：

End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of S5P_NRTI_L2__CO_____20191001T123303_20191001T123803_10188_01_010302_20191001T131513.zip or
        S5P_NRTI_L2__CO_____20191001T123303_20191001T123803_10188_01_010302_20191001T131513.zip.zip, and cannot find S5P_NRTI_L2__CO_____20191001T123303_20191001T123803_10188_01_010302_20191001T131513.zip.ZIP, period.

如果我尝试使用7zip，我会得到：

7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
p7zip Version 9.20 (locale=it_IT.UTF-8,Utf16=on,HugeFiles=on,4 CPUs)

Error: Can not open file as archive

似乎文件已损坏，但如果我尝试下载其他文件的错误仍然存在。我也尝试过用“doc.zip”这样简单一点的名字来改，都没有成功。我被卡住了，有什么想法吗？

我在遵循这个教程https://github.com/acgeospatial/Satellite_Imagery_Python/blob/master/SentinelSat_Demo.ipynb

Answer 1

有一个错误：https://github.com/sentinelsat/sentinelsat/issues/270该文件具有不正确的名称。邮政分机。如果我手动将扩展名从更改为。直截了当地说。nc并尝试用查看器脚本打开它，它可以工作。我想知道我链接的教程如何工作。

Answer 2

我想你的文件可能不是zip文件。转到该文件属性并检查其是否正确。zip格式与否。

我还想提一下，我无法打开你提到的存储库。
