Question

'Uzak uç tepkisi bağlantıyı kapattı' ı

import requests 
url ='http://eutils.ncbi.nlm.nih.gov/entrez/eutils/einfo.fcgi' 
r = requests.get(url) 
r.content 

url 3.5 tarayıcıda herhangi bir sorun ile açılabilir anakonda piton ile url veri getirmek çalışıyorum. ..

Ama (ben denemek bu url ve diğer herhangi bir url için) bir hata alıyorum:

import requests 
MAX_RETRIES = 20 
url ='http://eutils.ncbi.nlm.nih.gov/entrez/eutils/einfo.fcgi' 

session = requests.Session() 
adapter = requests.adapters.HTTPAdapter(max_retries=MAX_RETRIES) 
session.mount('https://', adapter) 
session.mount('http://', adapter) 

r = session.get(url) 
print(r.content)
