使用备用API或更改代码。

如果api.ipify.org api一直返回错误，可能是该API停止运行或出现问题。解决此问题的一种方法是使用备用API。以下是使用备用API的代码示例：

import requests
  
ip = ""
url = "https://api.ipify2.org/"
response = requests.get(url)
if response.status_code == 200:
    ip = response.text
else:
    # 备用API
    url = "https://api.ipify.org/"
    response = requests.get(url)
    if response.status_code == 200:
        ip = response.text

print(ip)

另一种解决方法是更改代码以处理ipify.org的错误。以下是使用try-except块处理错误的示例：

import requests
  
ip = ""
url = "https://api.ipify.org/"
try:
    response = requests.get(url)
    if response.status_code == 200:
        ip = response.text
except requests.exceptions.RequestException as e:
    # 发生错误
    print(str(e))
    # 使用备用API
    url = "https://api.ipify2.org/"
    response = requests.get(url)
    if response.status_code == 200:
        ip = response.text

print(ip)
