POST /sapi/v1/c2c/ads/getDetailByNo

Code below

import hmac
import time
import hashlib
import requests
from urllib.parse import urlencode

KEY = ""
SECRET = ""
BASE_URL = "https://api.binance.com"

def hashing(query_string):
    return hmac.new(
        SECRET.encode("utf-8"), query_string.encode("utf-8"), hashlib.sha256
    ).hexdigest()


def get_timestamp():
    return int(time.time() * 1000)


def dispatch_request(http_method):
    session = requests.Session()
    session.headers.update(
        {"Content-Type": "application/json;charset=utf-8", "X-MBX-APIKEY": KEY}
    )
    return {
        "GET": session.get,
        "DELETE": session.delete,
        "PUT": session.put,
        "POST": session.post,
    }.get(http_method, "GET")


# used for sending request requires the signature
def send_signed_request(http_method, url_path, payload={}):
    query_string = urlencode(payload, True)
    if query_string:
        query_string = "{}&timestamp={}".format(query_string, get_timestamp())
    else:
        query_string = "timestamp={}".format(get_timestamp())

    url = (
        BASE_URL + url_path + "?" + query_string + "&signature=" + hashing(query_string)
    )
    print("{} {}".format(http_method, url))
    params = {"url": url, "params": {}}
    response = dispatch_request(http_method)(**params)
    return response.json()


# used for sending public data request
def send_public_request(url_path, payload={}):
    query_string = urlencode(payload, True)
    url = BASE_URL + url_path
    if query_string:
        url = url + "?" + query_string
    print("{}".format(url))
    response = dispatch_request("GET")(url=url)
    return response.json()

params = {
    "adsNo":"11378191646449455104"
}

response = send_signed_request("POST", "/sapi/v1/c2c/ads/getDetailByNo", params)

response = send_signed_request("POST", "/sapi/v1/c2c/ads/updateStatus", params)
print(response)

I got an error

{'code': -1000, 'msg': 'An unknown error occurred while processing the request.'}

Please help. What am I doing wrong?

Looks like you are sending the parameters in your url and also in the body. Remove the parameters from the url and try again. Also try to urlencode the params before sending.
