JSONDecodeError: Expecting value: line 1 column 1 (char 0) when using google api

I'm using google api in python. My purpose is find and download any image similar with my image. This my error:
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

What was wrong with my code? I noticed response was return <Response [400]>, i guess it is problem with my code. How to fix it? Any help is appreciated. Below is the code:
import requests
import urllib.request
# Replace YOUR_API_KEY with your actual API key
api_key = "YOUR_API_KEY"
# Load the image you want to search for
# image_data = open("path/to/image.jpg", "rb").read()
image_data = open("C:\\Users\\Administrator\\Downloads\\theme\\3f559715-f407-47de-8540-1cd9e4fdc56c.jpg", "rb").read()
# Send the request to the Google Search API's "similar images" feature
response = requests.post(
"https://www.googleapis.com/customsearch/v1/similar?",
params={
"key": api_key,
# "cx": "YOUR_CX_VALUE", # Replace YOUR_CX_VALUE with your actual CX value
"cx": "d47119ff66e004d6b",
},
headers={
"Content-Type": "image/jpeg",
},
data=image_data,
)
# print(response) -><Response [400]>
# Get the search results from the response
results = response.json()["items"]
# Iterate through the search results and download the images
for result in results:
image_url = result["link"]
image_filename = image_url.split("/")[-1]
urllib.request.urlretrieve(image_url, image_filename)
print(f"Downloaded image: {image_filename}")

I want to automate the login to a website

I wrote the following code in PyCharm to login to a website automatically:
import requests
import json
def Login(username, password):
s = requests.Session()
payload = {
'username': username,
'password': password
}
res = s.post('https://domainNamePostUrl', json=payload)
s.headers.update({'authorization': json.loads(res.content)['token']})
print(res.content)
return s
Session = Login('realUserName', 'realPassword')
Session = Login('realUserName', 'realPassword') <-- This is line 17
When I run it, I get the following error:
/Users/PycharmProjects/pythonProject4/venv/bin/python /Users/PycharmProjects/pythonProject5/main.py
Traceback (most recent call last):
File "/Users/PycharmProjects/pythonProject5/main.py", line 17, in <module>

raise JSONDecodeError("Expecting value", s, err.value) from None

Can someone tell me where am I going wrong and where is the issue coming from?

json.decoder.JSONDecodeError while trying to show json data

I am working on a project where I have to scrape data from a website.I get 200 response while i run the code without json. But i am facing raise JSONDecodeError("Expecting value", s, err.value) from None json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) while displaying the json response.
here is my code:
import requests

In params I wrote True instead of JSON true . Is it causing the problem?

It's not working because the response is not a json. So you can't load it as a json. As simple as that.
Do r.text to see the response yourself.

JSONDecodeError expecting value: line 1 column 1

I've looked for similar questions, but I couldn't find anything what can help me. When i execute this code (which should work) I get "json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)"
TOKEN = '_EXAMPLE_TOKEN_'
def getPagedData(start,size):
url = 'http://EXAMPLE_URL'.format(start, size)
response = requests.get(url, headers={'token': TOKEN}, verify=False)
return response
def getDataInBatches():
start = 0
size = 1000
allData = []
data = getPagedData(start, size)
allData.extend(data.json()['data'])
total = data.json()['count']
for i in range(1, round(total/size) + 1):
print(allData[len(allData) - 1])
allData.extend(getPagedData(i * size, size).json()['data'])
return allData
print(getDataInBatches())

What can it be?

Make sure the response is in json format. The standard way to ensure the response is in json format is to add a headers={'Content-Type': 'application/json'}
But to be sure, check the documentation of an API you're accessing.

HTTPS urllib.request,read into JSON

If I go for example from urlib2
import urllib.request
response = urllib.request.urlopen('http://python.org/')
html = response.read()
then it works fine.
I was suprised to see that my code
req = urllib.request.Request('https://www.tehnomanija.rs/it-shop/laptop-racunari')
response = urllib.request.urlopen(req)
the_page = response.read()
data = json.loads(the_page)
print (data)
produces error like this
data = json.loads(the_page)
File "/home/mm/anaconda3/lib/python3.6/json/__init__.py", line 354, in loads
return _default_decoder.decode(s)
File "/home/mm/anaconda3/lib/python3.6/json/decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/home/mm/anaconda3/lib/python3.6/json/decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Except the other protocol I do not see why this would not work.

json.load() is for loading from file. You need json.loads():
data = json.loads(the_page)
