import requests
from requests.exceptions import RequestException

# 设置URL和请求数据
url = 'http://example.com/api/resource'
data = {'key1': 'value1', 'key2': 'value2'}

# 尝试发送POST请求
try:
    response = requests.post(url, json=data, timeout=10)  # 设置超时时间
    response.raise_for_status()  # 如果请求失败，会抛出HTTPError异常
    print(response.json())  # 假设服务器返回JSON响应
except RequestException as e:
    # 处理所有requests库抛出的异常，包括连接错误
    print(f"An error occurred while trying to send the POST request: {e}")
    # 在这里你可以尝试重试逻辑，例如：
    # 重试次数和间隔可以根据实际需求调整
    retries = 5
    retry_interval = 5  # seconds

        try:
