AttributeError: 'str' object has no attribute 'items' (python)

Question

I am trying to post data to api of website using this code:

import requests as r
import json


load={"accept": "application/json, text/plain, */*",
"accept-encoding": "gzip, deflate, br",
"accept-language": "en-US,en;q=0.9",
"content-length": "40",
"content-type": "application/json",
"origin": "www.mysite.com",
"referer": "www.mysite.com",
"sec-fetch-dest": "empty",
"sec-fetch-mode": "cors",
"sec-fetch-site": "cross-site",
"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.61 Safari/537.36 Edg/83.0.478.37",
}

pd={"version"="1.0"}
ro = r.post("api.mysite.com", headers=json.dumps(load),data=pd)


print(ro.status_code, ro.reason)

But I keep getting this error:

Traceback (most recent call last):
  File "test.py", line 18, in <module>
    ro = r.post("https://api.mysite.com", headers=json.dumps(load),data=pd)

for header in headers.items():
AttributeError: 'str' object has no attribute 'items'

I checked the type of load and it's dictionary. Any help is appreciated.

The code seems okay, did you try clearing your *.pyc files? — Alexander Santos

Yes I did, same error, I removed json.loads and just passed headers as it is but it's giving 403 code. — Ajay Kumar Chowdary

Since as you say, your load object is already a dictionary (which is json serializable, and has an items attribute) by writing

headers = json.dumps(load)

the json.dumps method is JSON encoding your load object into a string (which does not have an item method)

Try

headers = load

instead

Thank you it worked, but it keeps giving me 403 forbidden. Any idea why?

This is an error returned by the API which typically means that either you do not have access to the method or that you need to pass in some type of authentication in your request.

I passed the api key in header but still same error.
