问尝试检索transloadit中的程序集列表时出现INVALID_SIGNATURE错误

EN

params = {
    'auth': {
        'key': auth_key,
        'expires': expires
    },
    'template_id': template_id
}

# Converts the dictionary into JSON
message = json.dumps(params, separators=(',', ':'))
signature = hmac.new(auth_secret.encode('utf-8'),
                    message.encode('utf-8'),
                    hashlib.sha1).hexdigest()

# URL encodes it
params_encoded = urllib.parse.quote_plus(message)

url = f'https://api2.transloadit.com/assemblies?signature={signature}&params={params_encoded}'

response = requests.get(url)
