php is not changing header to application/json ( data sent from python to get json response)

Hi I have this php code:
<?php
$firstname = htmlspecialchars($_GET["firstname"]);
$lastname = htmlspecialchars($_GET["lastname"]);
$password = htmlspecialchars($_GET["password"]);
$result['username']=$firstname;
header('Content-Type: application/json; charset=utf-8');
echo json_encode($result);
exit ;
?>
And this python code:
import requests
def send(firstname,lastname,password):
userdata = {"firstname": firstname, "lastname":lastname , "password": password}
resp = requests.post('http://www.example.com/php.php', params=userdata)
print ( 'Content-Type:' )
print( resp.headers['Content-Type'])
getdata = resp.json()
print (getdata[ 'username' ] )
send('yama','last','password')
My python output is:
Content-Type:
text/html
Traceback (most recent call last):

So you can see in my output that Content-Type:
text/html and it is not application/json, What should I do?
I know this question is dublicated but I tryed everything on stackoverflow answers and my codes still not working for me!

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:

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}")

Unable to read API responce data

I am trying to get data from the below seen URLs
import requests
import json
service_a = requests.get('https:xxxxx')
service_b = requests.get('https:xxxxx')
service_a.json()
service_b.json()
While for the case of service_a, service_a.json() gives me the expected data, for service_b, the call service_b.json() gives me the following error:
Traceback (most recent call last):

raise JSONDecodeError(errmsg, string, idx)
simplejson.errors.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Why is this happening?
ps. I notced that when I try to visit the https link of service_a, the data it contains are shown in the browser, while for sevice_b, no data are shown in the browser, but when I click it a file with its data is downloaded in my computer.

Try to check the Content-Type of service_b response.
import csv
response = requests.get(API_URL)
decoded_data = response.content.decode("utf-8")
csv_data = csv.reader(decoded_data.splitlines(), delimiters=",")
csv_list = list(csv_data)

in most cases your
JSONDecodeError: Expecting value: line 1 column 1 (char 0)
error is due to:
non-JSON conforming quoting
XML/HTML output (that is, a string starting with <), or
incompatible character encoding

Python json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) with Spaces in path name

I am uploading a file to a REST API with a Python 3 script via the windows command line. The filename is an argument passed in to the script. Everything works fine unless there is a space in the path name. i.e. c:\temp\myFolder\1.jpg works, but c:\temp\my Folder\1.jpg throws an error:
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
The code up until the error is as follows:
def upload_photo(filename):
f = open(filename, "rb")
data = f.read()
data_md5 = hashlib.md5(data).hexdigest()
f.close()
r = requests.put('https://upload.mysite.com/{}'.format(filename), data=data)
response = json.loads(r.text)
I'm not sure how to fix it. Thanks for the help.

You need to encode the link properly; escaping the invalid character(s). You can do that with urllib.
>>> import urllib
>>> filename = urllib.parse.quote('c:\temp\my Folder\1.jpg')
>>> 'https://upload.mysite.com/' + filename
'https://upload.mysite.com/c%3A%09emp%5Cmy%20Folder%01.jpg'

python slackclient userslist

I am trying to use python slackclient.
I am getting json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) error for this, print (slack_client.api_call("users.list")) in the below code. I tried like this, but still getting error, print (json.loads(slack_client.api_call("users.list")))
please suggest what could be wrong,
the first 2 api calls works fine and return result. only the users list api call is giving me error
