59.(前端)重置密码实现——如何在前端vue使用后端flask接口重置密码为默认值
1.流程简介
1.1弹窗的设置
- 设置弹窗el-dialog，并且创建弹窗内容，传递选中栏的用户名与昵称
- 创建显示窗口的函数showReset
- 创建重置的图标
- 返回第二步中所用的变量名称，并设置是否默认显示
- 测试1：
1.2确认修改用户密码发送请求
- 发送get请求，传递获取到的id参数
- 判断状态码是否成功
- 关闭弹窗
- 重新获取数据
10.测试2
2.测试
2.1测试1——弹窗测试是否有效
2.2测试2——重置密码是否有效
首先，去到navicat中修改加密过后密码pwd
使用重置密码的按钮发送请求
前端测试结果
数据库测试结果
使用新密码登录测试结果
3.主要代码——弹窗函数与发送重置密码请求函数
// 显示重置密码的弹窗
showReset(row){
this.resetId = row.id
this.resetName = row.name
this.resetNickName = row.nick_name
this.resetDialogVisible = true
},
// 重置密码弹窗中的确认操作
async resetUser(){
const {data: res} = await this.$axios.get('/api/user/reset', {params: {id:this.resetId} })
if (res.status !== 200) return this.$msg.error(res.msg)
this.$msg.success(res.msg)
this.resetDialogVisible = false
this.getUserList()
}
