使用 pandas 读取在线数据时出现 HTTP 错误 413

Question

我正在使用 pandas read_csv 将文件下载并读取到数据帧。

import pandas as pd
df = pd.read_csv('https://some-monitor.com/rest/data', sep=';', thousands='.', decimal=',')

在本地，脚本工作正常，数据被读取到数据框。但是，当我 ssh 进入远程服务器并运行那里的脚本时，我收到以下错误：

  File "/usr/lib/python3/dist-packages/pandas/io/parsers.py", line 678, in parser_f
    return _read(filepath_or_buffer, kwds)
  File "/usr/lib/python3/dist-packages/pandas/io/parsers.py", line 424, in _read
    filepath_or_buffer, encoding, compression)
  File "/usr/lib/python3/dist-packages/pandas/io/common.py", line 195, in get_filepath_or_buffer
    req = _urlopen(filepath_or_buffer)
  File "/usr/lib/python3.7/urllib/request.py", line 222, in urlopen
    return opener.open(url, data, timeout)
  File "/usr/lib/python3.7/urllib/request.py", line 531, in open
    response = meth(req, response)
  File "/usr/lib/python3.7/urllib/request.py", line 641, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib/python3.7/urllib/request.py", line 569, in error
    return self._call_chain(*args)
  File "/usr/lib/python3.7/urllib/request.py", line 503, in _call_chain
    result = func(*args)
  File "/usr/lib/python3.7/urllib/request.py", line 649, in http_error_default
    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 413:

为什么会出现这种情况？为什么脚本在本地有效，而在服务器上却无效？服务器和我本地的 OS 都是一样的：Ubuntu.

感谢@DeadSec 的建议，脚本现在在服务器上也能正常运行。我使用 pretty-downloader 先下载文件，然后在 pandas.

加载它

from pretty_downloader import download
download('https://some-monitor.com/rest/data', file_name='my_file.csv')

import pandas as pd
df = pd.read_csv('my_file.csv', sep=';', thousands='.', decimal=',')
