在python中处理不成功的请求

try:
    # 处理请求的代码
    response = process_request()
    # 其他处理逻辑
except Exception as e:
    # 异常处理逻辑
    print("请求处理失败:", str(e))

class RequestFailedError(Exception):
    def __init__(self, message):
        self.message = message

try:
    # 处理请求的代码
    response = process_request()
    if response.status_code != 200:
        raise RequestFailedError("请求处理失败")
    # 其他处理逻辑
except RequestFailedError as e:
    # 自定义异常处理逻辑
    print("请求处理失败:", e.message)
except Exception as e:
    # 其他异常处理逻辑
    print("发生异常:", str(e))
