人生苦短_我用Python_Try_Exception异常捕捉_007

        except Exception as e:  # 捕捉异常
            print(‘请求失败,出现的错误是%s ‘ % e)
            # 错误抓起来,然后代码可以继续执行
            # try..Exception把异常信息获取到,并且对异常进行处理
            raise e  # 把异常抛出,因为异常捕捉到,还要将这个异常跑出来,不抛的话程序将异常视为正常,程序继续运行!


if __name__ == ‘__main__‘:
    http_res = HttpRequests(‘http://www.baidu.com‘)
    print(http_res.get_or_post(1))
