python POST request and null value - python

I'm using the following code , to do POST request on application level
url = 'http://www.webdev.com/web/POST'
headers = {'content-type': 'application/json'}
payload = {'name': 'name', 'status': 'success', 'newname': 'name'}
r = requests.post(url, data=json.dumps(payload), headers=headers)
r.text
r.status_code
r.connection.close()
from Python logs
send: 'POST /web/POST HTTP/1.1\r\nHost: www.webdev.com\r\nContent-Length: 189\r\nUser-Agent: python-requests/2.8.1\r\nConnection: keep-alive\r\nAccept: */*\r\nAccept-Encoding: gzip, deflate\r\n\r\n'
send: '{"name": "test1", "status": "sucsses", "newname": "name23"}'
reply: 'HTTP/1.1 200 OK\r\n'
but on the application level, it gives null value for the 3 vars.
The application is expecting the following format:
http://www.webdev.com/web/POST?name=test1&status=sucsses&newname=name23
I used curl command to do the post and application got the right value

You aren't passing your params as part of url and sending them in POST body, but server is waiting for GET params.
To pass your payload as GET parameters use params keyword argument:
r = requests.post(url, params=payload, headers=headers)
According to your url format you should ignore passing data, simply pass params.
Good luck!

How to post a request with python specifying the body raw

I am trying to send a JSON object using python but I am getting 422 error. Meanwhile, with postman I am able to post the JSON via the API:
First I enter the authentication in the Authorization and in the body I specify raw and choose JSON then I post the JSON object and get a 200 response.
But with python:
endpoint = "some endpoint"
url = host + endpoint
headers={"Accept": "application/json",
"Authorization": f"Bearer {bearer_token}"}
order = json.dumps(json_object, ensure_ascii=False)
send_data = requests.post(url, json=order, headers=headers)
print(send_data.json())
if send_data.status_code==200:
print("Order successfully sent")
else:
print(f"The following error was encountered. Error: {send_data.status_code}")
What could be wrong? please advise
try
headers={"Accept": "application/json",
"Authorization": f"Bearer {bearer_token}"}
send_data = requests.post(url, data=order, headers=headers)

REST API post request results in successful request but not creation

I've been trying to make a Post Request to my CRM API. The CRM API is very vague:
"You can use POST request when you wish to create records. You POST a JSON encoded string to the servers and it will return a single instance of the record."
POST /{object_name}
Example:
Request URL (POST):
/accounts
Request Body (JSON):
{
"name": "testing API"
}
I've had plenty of success making GET requests regularly, but POST is not working out so easily.
url = "https://apiv4.reallysimplesystems.com/accounts?<KEY>"
payload = {"name":"Ziggy","owner":"XYZ","addresscounty/state":"Awe","source":"Space"}
headers = {
'Content-Type': 'application/json',
'Cookie': 'XSRF-TOKEN=<TOK>; really_simple_systems_session=<KEY>'
}
response = requests.post(url, headers=headers, data=payload)
I get a status code 200 when I run this, but I'm really looking for that 201. The only clue that I've got to follow at this point is that when I run:
response.json()
I get the error:
JSONDecodeError: Expecting value: line 1 column 1 (char 0)
I've tried switching the response parameters to json:
response = requests.post(url, headers=headers, json=payload)
I've tried ensuring that my payload is json by using json.dumps():
payload = {"name":"Ziggy","owner":"XYZ","addresscounty/state":"Awe","source":"Space"}
payload = json.dumps(payload)
And I've tried all sorts of other shenanigans that I can't even recall at this point. Does anyone have any idea where I'm going wrong here? The 200 status code makes me feel painfully close.
Replace <AUTH_TOKEN> with your auth token
url = "https://apiv4.reallysimplesystems.com/accounts/"
payload = {"name":"Ziggy"}
headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer <AUTH_TOKEN>',
}
response = requests.post(url, headers=headers, data=payload)
Problem solved:
import json
import requests
url = "https://apiv4.reallysimplesystems.com/accounts"
payload = {"name":"RSS Test Joe Bloggs","addresscounty/state":"Maryland","source":"Word of Mouth"}
payload = json.dumps(payload)
headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer <AUTH KEY>'
}
response = requests.post(url, headers=headers, data=payload)
Rather than using Postman's code which included the in the URL and used :
'Cookie': 'XSRF-TOKEN=<TOK>; really_simple_systems_session=<KEY>'
I replaced it with a standard Authorization header. Secondly, I found that using json.dumps(payload) and json = payload was resulting in a Bad Request.

request to vCloud via API using python returns 406?

Based on vCloud API documentation user suppose to send the next query
POST https://vcloud.example.com/api/sessions

I am trying to do the same using python, see the method down below
def vcloud_send():
vcloud = requests.Session()
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
result = base64.b64encode(b'user#org:password')
headers = {'Authorization': b"encoded login:password",
'Accept': 'application/*+xml'}
response = vcloud.request('POST', url='https://host/api/session', headers=headers, verify=False)
return response
And I get 406
<Response [406]>
Please tell me why does this happen and what is a reason, because I expect to get a content

Python Request Post with param data

This is the raw request for an API call:
POST http://192.168.3.45:8080/api/v2/event/log?sessionKey=b299d17b896417a7b18f46544d40adb734240cc2&format=json HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: application/json
Content-Length: 86
Host: 192.168.3.45:8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
{"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}
This request returns a success (2xx) response.
Now I am trying to post this request using requests:
import requests
headers = {'content-type' : 'application/json'}
data ={"eventType" : "AAS_PORTAL_START",
"data" : {"uid": "hfe3hf45huf33545",
"aid": "1",
"vid": "1"}
}
url = ("http://192.168.3.45:8080/api/v2/event/log?"
"sessionKey=9ebbd0b25760557393a43064a92bae539d962103&"
"format=xml&"
"platformId=1")
requests.post(url, params=data, headers=headers)
The response from this request is
<Response [400]>
Everything looks fine to me and I am not quite sure what I posting wrong to get a 400 response.
params is for GET-style URL parameters, data is for POST-style body information. It is perfectly legal to provide both types of information in a request, and your request does so too, but you encoded the URL parameters into the URL already.
Your raw post contains JSON data though. requests can handle JSON encoding for you, and it'll set the correct Content-Type header too; all you need to do is pass in the Python object to be encoded as JSON into the json keyword argument.
You could split out the URL parameters as well:
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}
then post your data with:
import requests
url = 'http://192.168.3.45:8080/api/v2/event/log'
data = {"eventType": "AAS_PORTAL_START", "data": {"uid": "hfe3hf45huf33545", "aid": "1", "vid": "1"}}
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}
requests.post(url, params=params, json=data)
The json keyword is new in requests version 2.4.2; if you still have to use an older version, encode the JSON manually using the json module and post the encoded result as the data key; you will have to explicitly set the Content-Type header in that case:
import requests
import json
headers = {'content-type': 'application/json'}
url = 'http://192.168.3.45:8080/api/v2/event/log'
data = {"eventType": "AAS_PORTAL_START", "data": {"uid": "hfe3hf45huf33545", "aid": "1", "vid": "1"}}
params = {'sessionKey': '9ebbd0b25760557393a43064a92bae539d962103', 'format': 'xml', 'platformId': 1}
requests.post(url, params=params, data=json.dumps(data), headers=headers)
Assign the response to a value and test the attributes of it. These should tell you something useful.
response = requests.post(url,params=data,headers=headers)
response.status_code
response.text
status_code should just reconfirm the code you were given before, of course
Set data to this:
data ={"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}

Sending POST request to a webservice from python

I'm trying to send a POST request to a restful webservice. I need to pass some json in the request.It works with the curl command below
curl --basic -i --data '<json data string here>' -H Content-type:"text/plain" -X POST http://www.test.com/api
I need some help in making the above request from Python. To send this POST request from python I have the following code so far:
import urllib
url='http://www.test.com/api'
params = urllib.urlencode... #What should be here ?
data = urllib.urlopen(url, params).read()
I have the following three questions:
Is this the correct way to send the resuest ?.
How should i specify the params value ?
Does content-type need to be specified ?
Please Help
Thank You
The documentation for httplib has an example of sending a post request.
>>> import httplib, urllib
>>> params = urllib.urlencode({'#number': 12524, '#type': 'issue', '#action': 'show'})
>>> headers = {"Content-type": "application/x-www-form-urlencoded",
... "Accept": "text/plain"}
>>> conn = httplib.HTTPConnection("bugs.python.org")
>>> conn.request("POST", "", params, headers)
>>> response = conn.getresponse()
>>> print response.status, response.reason
302 Found
>>> data = response.read()
>>> data
'Redirecting to http://bugs.python.org/issue12524'
>>> conn.close()
Construct a dict of the data you want to be sent as a POST request.
urlencode the dict to get a string.
urlopen the URL you want, passing in the optional data parameter as your encoded POST data.
the question deals with sending the parameters as "json"..
you need to set the Content-Type to application/json in the headers and then send the paramters without urlencoding..
ex:
url = "someUrl"
data = { "data":"ur data"}
header = {"Content-Type":"application/json","User-Agent":"Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1)"}
#lets use httplib2
import httplib2
http = httplib2.Http()
response, send = http.request(url,"POST",headers=header,body=data)
You don't need urllib.urlencode() if Content-Type is not application/x-www-form-urlencoded:
import json, urllib2
data = {"some": "json", "d": ["a", "ta"]}
req = urllib2.Request("http://www.test.com/api", data=json.dumps(data),
headers={"Content-Type": "application/json"})
print urllib2.urlopen(req).read()
import requests
endpoint = 'https://xxxxxxxxxxxxxxxxxxx.com'
headers = {'Content-Type': 'text/plain'}
data = '{ id: 1 }'
result = requests.post(endpoint, headers=headers, data=data)
print(result)
Here's a sample snippet on POST request of json. The results will be printed in your terminal.
import urllib, urllib2
url = 'http://www.test.com/api'
values = dict(data=json.dumps({"jsonkey2": "jsonvalue2", "jsonkey2": "jsonvalue2"}))
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
rsp = urllib2.urlopen(req)
content = rsp.read()
print content
