Python http.client.RemoteDisconnected

问题

Trying to run several ids through a webservice using python and I am getting the 'http.client.RemoteDisconnected: Remote end closed connection without response' error. I don't want to try/catch this error, I want to investigate why I am getting this response. I have been able to get 400 and 500 level errors

raise HTTPError(req.full_url, code, msg, hdrs, fp)
    urllib.error.HTTPError: HTTP Error 413:

using the method I am including below, and I understood those errors (so I don't believe the error is related to how I have coded this but who knows)

import pandas as pd
from urllib.parse import urlencode
import urllib.request
contact = ""
url = 'https://www.uniprot.org/uploadlists/'
mouse_ten_tissues = pd.read_csv('Z:\\\mouse_data\\refex\\RefEx_expression_RNAseq10_mouse_PRJNA30467.tsv',
                            delimiter='\t', encoding='utf-8')
mouse_ten_refseq = mouse_ten_tissues['NCBI_RefSeqID'].to_string()
query_mouse_human_refseq_id_params = {
    'from': 'REFSEQ_NT_ID',
    'to': 'GENENAME',
    'format': 'tab',
    'query': mouse_ten_refseq
}

query_mouse_human_refseq_id_data = urlencode(query_mouse_human_refseq_id_params).encode("utf-8")
query_mouse_human_refseq_id_request = urllib.request.Request(url, query_mouse_human_refseq_id_data)
query_mouse_human_refseq_id_request.add_header('User-Agent', 'Python %s' % contact)

query_mouse_human_refseq_id_response = urllib.request.urlopen(query_mouse_human_refseq_id_request)

with query_mouse_human_refseq_id_response as f:
    query_mouse_human_refseq_id_resp = f.read()

The error I get is:

Traceback (most recent call last):

    raise RemoteDisconnected("Remote end closed connection without"
http.client.RemoteDisconnected: Remote end closed connection without response

I've been reading through the documentation but I don't know how to get a more descriptive error or how to debug. Should I assume that it's a time out issue or that the list I am submitting is too large? I haven't been able to find much in the way of explanation through my google exploration of the issue.

回答1:

The best answer was a comment. Most likely I am hitting issues due to my internet speed/spotty internet, as sometime response is received and sometimes no response.
