基于SpringBoot的QQ邮箱登录注册及找回密码有关的操作

基于SpringBoot的登录注册及找回密码有关的邮箱验证码操作

通过输入的邮箱发送验证码，检验输入的验证码是否和后台生成的一致，若一致，将用户数据写入数据库，完成注册；

通过输入用户名和密码与数据库中一条数据进行对比，若一致，则登陆成功

首先校验数据库中是否存在用户名及其密码，存在时，再调用发送验证码进行比对的方式进行修改密码

登录QQ邮箱后，点击左上方的设置，选择账户

然后一直往下滑，看到POP3/SMTP服务，点击开启，应该会让帮定的手机号发个短信，然后会收到一个授权码，一定要好好保存，在appliction.properties配置中会用到。

5使用postman测试 
测试发送邮件 
请求url：http://localhost:8088/sendEmail?email=1223334444@qq.com
 
**请求方式: ** post
 
 
随机生成的验证码
 
[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-w8bnwFWb-1636107494747)(README.assets/image-20211105173824158.png)]
 
发送的邮件验证码
 
 
测试注册 
请求url：http://localhost:8088/register?username=王五&password=123456&email=1223334444@qq.com&code=496300
 
**请求方式: ** post
 
code值是上面已发送的验证码
 
 
测试登录 
请求url：http://localhost:8088/login?username=王五&password=123456
 
**请求方式: ** post
 
 
测试找回密码 
找回密码分为两步: 第一步校验用户名和邮箱是否都存在, 第二步若存在发送邮箱
 
校验用户名和邮箱 
请求url：http://localhost:8088/verify?username=王五&email=1223334444@qq.com
 
**请求方式: ** post
 
 
修改用户密码 
校验到用户名和密码同时存在, 发送邮箱
 
发送邮箱 
 
邮箱中的验证码和idea中的验证码
 
 
修改密码 
 
注意: 在找回密码这一步骤中, 如果没有校验到数据中用户名和邮箱, 是不可以发送邮箱的,这一步骤主要在ajax中体现
