однако это тоже не принесло никаких результатов, ошибка все та же
Искал решение проблемы, но все они для макоси, в то время как у меня это все происходит на винде. Питон версии 3.7.3

One solution is to set the value of when a program continues, which typically stores the response as a default. Regarding handling exceptions in Python library Requests, if there is a network issue such as a refused connection or an internet problem, a ConnectionError exception will be raised.

Verification states that the server can access Google, and a successful curl result was obtained.
Solution:
The second website, identified by
https://web1.com/
, is no longer functioning and as a result, requests is raising an exception. To rectify this issue, you must intercept and investigate it.
import requests
dns = ['www.google.com', 'web1.com']
for obj in dns:
url = "https://" + obj
try:
response = requests.get(url, verify=False, timeout=5)

Question:
I am attempting to establish communication between two files, namely
Django
and
Python
, but encountering an error message as follows:
The following error occurred while making a request:
httpconnectionpool
(host=’127.0.0.1′, port=8000). The error was caused by
newconnectionerror
(‘:
Failed to establish a new connection
:
[winerror 10061] no connection could be made because the target machine actively refused it
‘), and it resulted in reaching the maximum
retries exceeded
for the URL /api/1/.
Having developed a Python application, marked as
file named
, I am attempting to establish communication between
test.py
and
Django
. Specifically, the code in my
Pytho
file is as follows:
import requests
BASE_URL='http://127.0.0.1:8000/'
ENDPOINT='api/'
def get_resource(id):
resp=requests.get(BASE_URL+ENDPOINT+id+'/')
print(resp.status_code)
print(resp.json())
id=input("Enter some ID: ")
get_resource(id)

contains:-
from django.db import models
# Create your models here.
class Employee(models.Model):
eno=models.IntegerField()
ename=models.CharField(max_length=70)
esal=models.FloatField()
eaddr=models.CharField(max_length=100)

]
Getting error like :
The code threw an exception due to a connection error while attempting to establish a connection with the API at host ‘127.0.0.1’ and port 8000. The error message indicates that a new connection could not be established because there was no network connection available.
Can any techies assist me? I appreciate your help in advance.
Solution 1:
The actual cause of the failure was due to running only py test.py from a single terminal to access
python file
, which was not possible as the server was not running at that time. However, after opening a separate terminal and running the Dev server, my Python file was able to communicate with the Django file, and the issue was resolved. Currently, everything is working perfectly.
Solution 2:
Try this :
import requests
# BASE_URL='http://127.0.0.8000' <<< Url with port malformed
BASE_URL='http://127.0.0.1:8000'
ENDPOINT='api/'
def get_resource():
# resp=requests.get(BASE_URL+ENDPOINT) <<< Request url malformed
resp=requests.get(BASE_URL+"/"+ENDPOINT)
print(resp.status_code)
print(resp.json())
get_resource()
Solution 3:
All you have to do is launch a distinct terminal and execute your Python code.
make sure your server is running at that time
Solution 4:
The problem was resolved by changing the port number, which was the same issue faced earlier.

Python requests — Exception Type: ConnectionError
Question:
I am relying on a web service to fetch information for my website, but occasionally the URL fails, causing the site to be inaccessible. Can you advise me on how to manage this exception and ensure that the website continues to function even if the web service is unavailable?
Django Version: 1.3.1
Exception Type: ConnectionError
Exception Value:
HTTPConnectionPool(host='test.com', port=8580): Max retries exceeded with url:
I used
try:
r = requests.get("http://test.com", timeout=0.001)
except requests.exceptions.RequestException as e: # This is the correct syntax
print e
sys.exit(1)
but nothing happens
Solution:
Avoid exiting your worker instance and ensure you are capturing the correct Error. Additionally, review your
sys.exit(1)
carefully.
One example of what you could do is:
from requests.exceptions import ConnectionError
try:
r = requests.get("http://example.com", timeout=0.001)
except ConnectionError as e: # This is the correct syntax
print e
r = "No response"
In this scenario, your program will proceed by assigning the value of
r
, which generally stores the default response.
Requests.exceptions.ConnectionError: (‘Connection, you might already figured this out. Any way, I had a similar problem while making post requests in a for loop, which run 400 times, each loop run with two requests and a last request after exiting the loop. I found out while making API requests the server (check_mk) was not ready, still compiling some hots and …
Python requests exception handling
Question:
What is the process of using the Python library requests to
handle exceptions
?
As an instance, how can one determine if
PC connected
has internet connectivity?
When I try
try:
requests.get('http://www.google.com')
except ConnectionError:
# handle the exception
An error occurs stating that
ConnectionError
is undefined.
Solution 1:
If
import requests
is completed, the objective is to obtain
requests.ConnectionError
. An API documentation is provided here for
ConnectionError
, which is a specific case defined by
requests
.
Thus the code should be :
try:
requests.get('http://www.google.com')
except requests.ConnectionError:
# handle the exception
Solution 2:
In accordance with the documentation, the following items have been included:
-
If there is a problem with the network, such as a connection refusal due to an internet issue, Requests will generate an exception called ConnectionError.
try: requests.get('http://www.google.com') except requests.ConnectionError: # handle ConnectionError the exception -
Requests have a mechanism to handle invalid HTTP responses, where an HTTPError exception is raised. The method Response.raise_for_status() is responsible for detecting unsuccessful status codes and triggering an HTTPError exception.
try: r = requests.get('http://www.google.com/nowhere') r.raise_for_status() except requests.exceptions.HTTPError as err: #handle the HTTPError request here -
If a request times out, an exception called Timeout will be triggered.
It is possible to set a timeout argument in Requests, which allows you to specify the number of seconds that the program should wait for a response before stopping.
requests.get('https://github.com/', timeout=0.001) # timeout is not a time limit on the entire response download; rather, # an exception is raised if the server has not issued a response for # timeout seconds -
A base handler can have the appearance of inheriting all exceptions that Requests explicitly raises from requests.exceptions.RequestException.
try: r = requests.get(url) except requests.exceptions.RequestException as e: # handle all the errors here
Solution 3:
In fact,
requests.get()
can produce numerous exceptions beyond
ConnectionError
. Below are some examples I have observed during production:
from requests import ReadTimeout, ConnectTimeout, HTTPError, Timeout, ConnectionError
try:
r = requests.get(url, timeout=6.0)
except (ConnectTimeout, HTTPError, ReadTimeout, Timeout, ConnectionError):
continue
Solution 4:
for clarity, that is
except requests.ConnectionError:
NOT
import requests.ConnectionError
It is possible to capture a general exception, but experts suggest avoiding this approach.
