Loadrunner随机生成15位数字串 PS:http://www.51testing.com/html/43/6343-19789.html 今天看到一个网友的问题,是想生成一个15位的数字串来进行参数化输入,要求如下:1.前4位均是04362.其余的是11位的随机数原帖地址:http://bbs.51testing.com/viewthread.php?tid=89018&page=1&extra=page%3D1 拿到问题,我思考了一下,前4位使用固定值很好办,唯一的问题就是生成随

python 实现随机生成包8位包含大写字母.小写字母和数字的密码的程序.要求:1用户输入多少次就生成多少条密码,2要求密码必须同时包含大写字母.小写字母和数字,长度8位,不能重复代码如下: import string, random src_upp = string.ascii_uppercase src_let = string.ascii_lowercase src_num = string.digits lis = [] count = input('请输入次数:').strip() #

生成6位随机数字其实很简单,只需一行代码,具体如下: String verifyCode = String.valueOf(new Random().nextInt(899999) + 100000); 具体实现发送短信验证码功能,以注册为例,其实现代码如下: 这里需要用到第三方短信验证码接口,这里用到的是乐信短信验证码接口,乐信接口API文档说明(http://www.lx598.com/apitext.html),乐信java调用短信验证码接口 demo(http://www.lx598.c
