How to send POST request?
This is a solution without any external pip dependencies, but works only in Python 3+ (Python 2 won't work):
from urllib.parse import urlencode
from urllib.request import Request, urlopen
url = 'https://httpbin.org/post' # Set destination URL here
post_fields = {'foo': 'bar'} # Set POST fields here
request = Request(url, urlencode(post_fields).encode())
json = urlopen(request).read().decode()
print(json)
Sample output:
{
"args": {},
"data": "",
"files": {},
"form": {
"foo": "bar"
},
"headers": {
"Accept-Encoding": "identity",
"Content-Length": "7",
"Content-Type": "application/x-www-form-urlencoded",
"Host": "httpbin.org",
"User-Agent": "Python-urllib/3.3"
},
"json": null,
"origin": "127.0.0.1",
"url": "https://httpbin.org/post"
}
You can't achieve POST requests using urllib
(only for GET), instead try using requests
module, e.g.:
Example 1.0:
import requests
base_url="www.server.com"
final_url="/{0}/friendly/{1}/url".format(base_url,any_value_here)
payload = {'number': 2, 'value': 1}
response = requests.post(final_url, data=payload)
print(response.text) #TEXT/HTML
print(response.status_code, response.reason) #HTTP
Example 1.2:
>>> import requests
>>> payload = {'key1': 'value1', 'key2': 'value2'}
>>> r = requests.post("http://httpbin.org/post", data=payload)
>>> print(r.text)
{
...
"form": {
"key2": "value2",
"key1": "value1"
},
...
}
Example 1.3:
>>> import json
>>> url = 'https://api.github.com/some/endpoint'
>>> payload = {'some': 'data'}
>>> r = requests.post(url, data=json.dumps(payload))
If you really want to handle with HTTP using Python, I highly recommend Requests: HTTP for Humans. The POST quickstart adapted to your question is:
>>> import requests
>>> r = requests.post("http://bugs.python.org", data={'number': '12524', 'type': 'issue', 'action': 'show'})
>>> print(r.status_code, r.reason)
200 OK
>>> print(r.text[:300] + '...')

Use requests
library to GET, POST, PUT or DELETE by hitting a REST API endpoint. Pass the rest api endpoint url in url
, payload(dict) in data
and header/metadata in headers
import requests, json
url = "bugs.python.org"
payload = {"number": 12524,
"type": "issue",
"action": "show"}
header = {"Content-type": "application/x-www-form-urlencoded",
"Accept": "text/plain"}
response_decoded_json = requests.post(url, data=payload, headers=header)
response_json = response_decoded_json.json()
print(response_json)
