Question

我正在尝试在python应用程序中使用try catch方法。我不确定我是在缩进问题还是其他问题上犯了什么错误

这是我的代码。

try:
            ivurl = f'{api}/company/{id}/contacts?'
            payload: Dict[str, Union[bool, int]] = {'id': True}
            response = get_iv_response(url=ivurl, payload=payload)
            email_contact_totalresult: int = response.get('totalResults')
            email = int(email_contact_totalresult)
            payload: Dict[str, Union[bool, int]] = {'name': True}
            response = get_iv_response(url=ivurl, payload=payload)
            phone_contact_totalresult: int = response.get('totalResults')
            phone = int(phone_contact_totalresult)
            print ("here")
            if email > 0 or phone > 0:
                print (f"{id} has contacts")
                update_query = f"""update section 
                                set has_contact = true ,
                                updated = '{cur_date}'      
                            where name = '{id}'
                            """
                print(update_query)
                insert_query = f"""insert into quota(name,age)
                                values ('{name}',
                                        '{age}')"""
                print (insert_query)
                cursor.execute(update_query)
                cursor.execute(insert_query)
            
                conn.commit()
            else :
                print (f"{id} doesnot  has contacts")

        except:requests.RequestException as error1:
            print ("error1:",error1)
        # except requests.exceptions.HTTPError as error2:
        #     print ("error1:",error2)
        # except requests.exceptions.ConnectionError as error3:
        #     print ("error3:",error3)
        # except requests.exceptions.Timeout as error4:
        #     print ("error4:",error4)

    print ("job done")
    print(end_time)
    print('Duration: {}'.format(end_time - start_time))

我在“ as”无效语法附近遇到错误

语法应如下所示：

try:
    #this expression was not defined anywhere, hence the NameError
    print(leromipsum) 
except NameError as error1:
    print("meh")

因此，在您的代码中，我认为您应在删除标识之前：

except:requests.RequestException as error1:
    print ("error1:",error1)

并在除去以下内容后除去结肠：

except requests.RequestException as error1:
    print ("error1:",error1)

欢呼

编辑：

try:
    print("this code runs")
    raise requests.HTTPError
    print("this code is skipped, if an error occurs")
except requests.RequestException as error1:
    print ("error1:",error1)
except requests.exceptions.HTTPError as error2:
    print ("error1:",error2)
except requests.exceptions.ConnectionError as error3:
    print ("error3:",error3)
except requests.exceptions.Timeout as error4:
    print ("error4:",error4)

这个最小的示例对我有用。
