示例代码(使用Python和腾讯云API):
import requests
def add_to_whitelist(domain):
url = "https://api.example.com/whitelist"
headers = {
"Authorization": "Bearer YOUR_API_KEY",
"Content-Type": "application/json"
}
data = {
"domain": domain
}
response = requests.post(url, headers=headers, json=data)
if response.status_code == 200:
print(f"Added {domain} to whitelist")
else:
print(f"Failed to add {domain} to whitelist")
def remove_from_whitelist(domain):
url = "https://api.example.com/whitelist"
headers = {
"Authorization": "Bearer YOUR_API_KEY",
"Content-Type": "application/json"
}
data = {
"domain": domain,
"action": "remove"
}
response = requests.post(url, headers=headers, json=data)
if response.status_code == 200:
print(f"Removed {domain} from whitelist")
else:
print(f"Failed to remove {domain} from whitelist")
# 示例调用
add_to_whitelist("example.com")
remove_from_whitelist("example.com")
