import json

# URL to Annotation Lab
API_URL = "https://123.45.67.89"
# Add user credentials
USERNAME = "user"
PASSWORD = "password"
# The above video shows how to get CLIENT_ID and CLIENT_SECRET
CLIENT_ID = "..."
CLIENT_SECRET = "..."

PROJECT_NAME = "sample_project"


IDENTITY_MANAGEMENT_URL = API_URL + "/auth/"
IDENTITY_MANAGEMENT_REALM = "master"
HEADERS = {
    "Host": API_URL.replace("http://", "").replace("https://", ""),
    "Origin": API_URL,
    "Content-Type": "application/json",
}


def get_cookies():
    url = f"{IDENTITY_MANAGEMENT_URL}realms/{IDENTITY_MANAGEMENT_REALM}/protocol/openid-connect/token"
    data = {
        "grant_type": "password",
        "username": USERNAME,
        "password": PASSWORD,
        "client_id": CLIENT_ID,
        "client_secret": CLIENT_SECRET,
    }
    auth_info = requests.post(url, data=data).json()
    cookies = {
        "access_token": f"Bearer {auth_info['access_token']}",
        "refresh_token": auth_info["refresh_token"],
    }
    return cookies


def create_project():
    # GET THIS FROM SWAGGER DOC
    url = f"{API_URL}/api/projects/create"
    data = {
        "project_name": PROJECT_NAME,
        "project_description": "",
        "project_sampling": "uniform",
        "project_instruction": "",
    }
    r = requests.post(
        url, headers=HEADERS, data=json.dumps(data), cookies=get_cookies()
    )
    return r
