I'm attempting to use Bing's Entity search API, however I need to go through a proxy in order to establish a connection.
My company has giving me a proxy in the following format to use: 'http://username:password#webproxy.subdomain.website.com:8080'
I've tried using HTTPConnection.set_tunnel(host, port=None, headers=None) with no avail. Does anyone have any idea how to run the following Python query below using the proxy I was provided?
import http.client, urllib.parse
import json
proxy = 'http://username:pwd#webproxy.subdomain.website.com:8080'
subscriptionKey = 'MY_KEY_HERE'
host = 'api.cognitive.microsoft.com'
path = '/bing/v7.0/entities'
mkt = 'en-US'
query = 'italian restaurants near me'
params = '?mkt=' + mkt + '&q=' + urllib.parse.quote (query)
def get_suggestions ():
headers = {'Ocp-Apim-Subscription-Key': subscriptionKey}
conn = http.client.HTTPSConnection(host)
conn.request("GET", path + params, None, headers)
response = conn.getresponse()
return response.read()
result = get_suggestions ()
print (json.dumps(json.loads(result), indent=4))
As a side note, I was able to run the following sucessfully with the proxy.
nltk.set_proxy('http://username:pwd#webproxy.subdomain.website.com:8080')
nltk.download('wordnet')
I ended up using the requests package, they make it very simple to channel your request through a proxy, sample code below for reference:
import requests
proxies = {
'http': f"http://username:pwd#webproxy.subdomain.website.com:8080",
'https': f"https://username:pwd#webproxy.subdomain.website.com:8080"
}
url = 'https://api.cognitive.microsoft.com/bing/v7.0/entities/'
# query string parameters
params = 'mkt=' + 'en-US' + '&q=' + urllib.parse.quote (query)
# custom headers
headers = {'Ocp-Apim-Subscription-Key': subscriptionKey}
#start session
session = requests.Session()
#persist proxy across request
session.proxies = proxies
# make GET request
r = session.get(url, params=params, headers=headers)
If you use urlib2 or requests, the easiest way to configure a proxy is setting the HTTP_PROXY or the HTTPS_PROXY environment variable:
export HTTPS_PROXY=https://user:pass#host:port
This way the library handles the proxy configuration for you, and if your code runs inside a container you can pass that information at runtime.
I'm building a small script to test the certain proxies against the API.
It seems that the actual request isn't trigger under the provided proxy. For example, the following request will be valid and I will get an response from the API.
import requests
r = requests.post("https://someapi.com", data=request_data,
proxies={"http": "http://999.999.999.999:1212"}, timeout=5)
print(r.text)
How come I get the response even if the proxy provided was invalid?
You can define the proxies like this;
import requests
pxy = "http://999.999.999.999:1212"
proxyDict = {
'http': pxy,
'https': pxy,
'ftp': pxy,
'SOCKS4': pxy
}
r = requests.post("https://someapi.com", data=request_data,
proxies=proxyDict, timeout=5)
print(r.text)
I want to connect to a website with Proxy and stay connected there, for let's say 10 seconds.
My script:
import requests
url = 'http://WEBSITE.com/'
proxies ={'http': 'http://IP:PORT'}
s = requests.Session();
s.proxies.update(proxies)
s.get(url);
As much as I learnt, I came up with this script which connects to the website but I think it does not stay connected, what should I do so this script connects to the website with proxy and stays connected?
The Session object doesn't necessarily keep the connection alive. To that end this might work:
import requests
url = 'http://WEBSITE.com/'
proxies = {'http': 'http://IP:PORT'}
headers = {
"connection" : "keep-alive",
"keep-alive" : "timeout=10, max=1000"
}
s = requests.Session();
s.proxies.update(proxies)
s.get(url, headers=headers);
See connection, and keep-alive headers :)
edit: after reviewing the requests documentation, I learned that the Session object can also be used to store headers. Here is a slightly better answer:
import requests
url = 'http://WEBSITE.com/'
proxies = {'http': 'http://IP:PORT'}
headers = {
"connection" : "keep-alive",
"keep-alive" : "timeout=10, max=1000"
}
s = requests.Session()
s.proxies.update(proxies)
s.headers.update(headers)
s.get(url)
If I supply None or an empty dict to the proxies parameter, requests will automatically fall back to the proxies configured for the operating system as obtained through urllib.request.getproxies() (Python 3) / urllib.getproxies().
import requests
r = requests.get('http://google.com', proxies = {}) # or = None...
print(r.text)
Specifying proxies = { 'http': False } will even cause requests to hang completely for whatever weird reason.
So how do I direct requests to perform HTTP requests directly, without any proxy ?
Turns out you have to use an empty string for the protocol you want to use a direct connection:
r = requests.get('http://google.com', proxies = { 'http': '', ... })
Weird, but that's life.
Just a short, simple one about the excellent Requests module for Python.
I can't seem to find in the documentation what the variable 'proxies' should contain. When I send it a dict with a standard "IP:PORT" value it rejected it asking for 2 values.
So, I guess (because this doesn't seem to be covered in the docs) that the first value is the ip and the second the port?
The docs mention this only:
proxies – (optional) Dictionary mapping protocol to the URL of the proxy.
So I tried this... what should I be doing?
proxy = { ip: port}
and should I convert these to some type before putting them in the dict?
r = requests.get(url,headers=headers,proxies=proxy)
The proxies' dict syntax is {"protocol": "scheme://ip:port", ...}. With it you can specify different (or the same) proxie(s) for requests using http, https, and ftp protocols:
http_proxy = "http://10.10.1.10:3128"
https_proxy = "https://10.10.1.11:1080"
ftp_proxy = "ftp://10.10.1.10:3128"
proxies = {
"http" : http_proxy,
"https" : https_proxy,
"ftp" : ftp_proxy
}
r = requests.get(url, headers=headers, proxies=proxies)
Deduced from the requests documentation:
Parameters:
method – method for the new Request object.
url – URL for the new Request object.
...
proxies – (optional) Dictionary mapping protocol to the URL of the proxy.
...
On linux you can also do this via the HTTP_PROXY, HTTPS_PROXY, and FTP_PROXY environment variables:
export HTTP_PROXY=10.10.1.10:3128
export HTTPS_PROXY=10.10.1.11:1080
export FTP_PROXY=10.10.1.10:3128
On Windows:
set http_proxy=10.10.1.10:3128
set https_proxy=10.10.1.11:1080
set ftp_proxy=10.10.1.10:3128
You can refer to the proxy documentation here.
If you need to use a proxy, you can configure individual requests with the proxies argument to any request method:
import requests
proxies = {
"http": "http://10.10.1.10:3128",
"https": "https://10.10.1.10:1080",
}
requests.get("http://example.org", proxies=proxies)
To use HTTP Basic Auth with your proxy, use the http://user:password#host.com/ syntax:
proxies = {
"http": "http://user:pass#10.10.1.10:3128/"
}
I have found that urllib has some really good code to pick up the system's proxy settings and they happen to be in the correct form to use directly. You can use this like:
import urllib
...
r = requests.get('http://example.org', proxies=urllib.request.getproxies())
It works really well and urllib knows about getting Mac OS X and Windows settings as well.
The accepted answer was a good start for me, but I kept getting the following error:
AssertionError: Not supported proxy scheme None
Fix to this was to specify the http:// in the proxy url thus:
http_proxy = "http://194.62.145.248:8080"
https_proxy = "https://194.62.145.248:8080"
ftp_proxy = "10.10.1.10:3128"
proxyDict = {
"http" : http_proxy,
"https" : https_proxy,
"ftp" : ftp_proxy
}
I'd be interested as to why the original works for some people but not me.
Edit: I see the main answer is now updated to reflect this :)
If you'd like to persisist cookies and session data, you'd best do it like this:
import requests
proxies = {
'http': 'http://user:pass#10.10.1.0:3128',
'https': 'https://user:pass#10.10.1.0:3128',
}
# Create the session and set the proxies.
s = requests.Session()
s.proxies = proxies
# Make the HTTP request through the session.
r = s.get('http://www.showmemyip.com/')
8 years late. But I like:
import os
import requests
os.environ['HTTP_PROXY'] = os.environ['http_proxy'] = 'http://http-connect-proxy:3128/'
os.environ['HTTPS_PROXY'] = os.environ['https_proxy'] = 'http://http-connect-proxy:3128/'
os.environ['NO_PROXY'] = os.environ['no_proxy'] = '127.0.0.1,localhost,.local'
r = requests.get('https://example.com') # , verify=False
The documentation
gives a very clear example of the proxies usage
import requests
proxies = {
'http': 'http://10.10.1.10:3128',
'https': 'http://10.10.1.10:1080',
}
requests.get('http://example.org', proxies=proxies)
What isn't documented, however, is the fact that you can even configure proxies for individual urls even if the schema is the same!
This comes in handy when you want to use different proxies for different websites you wish to scrape.
proxies = {
'http://example.org': 'http://10.10.1.10:3128',
'http://something.test': 'http://10.10.1.10:1080',
}
requests.get('http://something.test/some/url', proxies=proxies)
Additionally, requests.get essentially uses the requests.Session under the hood, so if you need more control, use it directly
import requests
proxies = {
'http': 'http://10.10.1.10:3128',
'https': 'http://10.10.1.10:1080',
}
session = requests.Session()
session.proxies.update(proxies)
session.get('http://example.org')
I use it to set a fallback (a default proxy) that handles all traffic that doesn't match the schemas/urls specified in the dictionary
import requests
proxies = {
'http': 'http://10.10.1.10:3128',
'https': 'http://10.10.1.10:1080',
}
session = requests.Session()
session.proxies.setdefault('http', 'http://127.0.0.1:9009')
session.proxies.update(proxies)
session.get('http://example.org')
i just made a proxy graber and also can connect with same grabed proxy without any input
here is :

It’s a bit late but here is a wrapper class that simplifies scraping proxies and then making an http POST or GET:

Already tested, the following code works. Need to use HTTPProxyAuth.
import requests
from requests.auth import HTTPProxyAuth
USE_PROXY = True
proxy_user = "aaa"
proxy_password = "bbb"
http_proxy = "http://your_proxy_server:8080"
https_proxy = "http://your_proxy_server:8080"
proxies = {
"http": http_proxy,
"https": https_proxy
}
def test(name):
print(f'Hi, {name}') # Press Ctrl+F8 to toggle the breakpoint.
# Create the session and set the proxies.
session = requests.Session()
if USE_PROXY:
session.trust_env = False
session.proxies = proxies
session.auth = HTTPProxyAuth(proxy_user, proxy_password)
r = session.get('https://www.stackoverflow.com')
print(r.status_code)
if __name__ == '__main__':
test('aaa')
I share some code how to fetch proxies from the site "https://free-proxy-list.net" and store data to a file compatible with tools like "Elite Proxy Switcher"(format IP:PORT):
