捡个七
调试遇到的问题与解决方法
-
httplib模块的导入
也是百度了才知道python3.x不用httplib这个名字改用http.client这个名字了。 -
接口用例表的设计
这一块也是百度查找了Navicat 如何用sql脚本创建表的相关知识后,创建完成了接口用例表,并添加了数据进去。 -
报错:TypeError:string indices must be intergers(字符串索引必须是整数)
看了 @倔强的潇洒小姐 的发送http问题汇总的文章,也有类似的报错。 看了下她的解决方法,发现我在mysql.py文件里已经设置过了
cur = conn.cursor(cursorclass=pymysql.cursors.DictCursor)
,所以只能从其他地方下手查找错误。接着看到了红字下面的数据库的报错才发现代码里把params_interface写成了param_interface了,修改完成后,就不报错了。
课程内容备忘
- config.py的作用:
这个py文件是配置文件,用来存储固定的数据 - __http_code前面两个下划线的作用:
前面添加两个下划线是说明该方法是静态的,被隐藏的,不能被除它所在的py文件外的任何方法调用。而它自身所在py文件下的方法调用它的话,得在前面加个self,如:self.__http_code
完整源码:
# coding:utf-8
import requests
import http.client
import os
import logging
import json
import config
import mysql
class RequestInterface(object):
# 判断接口地址HTTP状态是否200
def __http_code(self, url): ## __该方法被隐藏不能被py文件外的其他方法调用
try:
if url != '':
r = requests.get(url)
code = r.status_code
else:
code = '1000' # 请求参数错误
except Exception as error: # 记录日志到log.txt文件

感谢
超感谢大婶和川叔提供的学习接口自动化的测试课程,确实颠覆了我的很多想法,也在以结果为导向反推的课程教学模式下,能够更多地去自查自学自我总结和分享反馈。
