1.前端发送网络请求(axios)

请求部分:
{
//发起网络请求,
this.axios.post('http://localhost:3312/sys-user/register', this.ruleForm).then((resp) => {
console.log(resp);
let data = resp.data;
console.log(data);
//检验注册是否成功
if (data.success) {
//清空表单数据
this.ruleForm = {};
//发送成功通知
this.$message({
message: '恭喜你,注册成功,点击去登陆按钮进行登陆吧!!!',
type: 'success'
});
}
})
this.$router.push({ path: '/login' })
}
2.表单验证:
if (this.ruleForm.password != this.ruleForm.checkPass) {
this.$message({
message: '两次输入密码不一致!!!',
type: 'error'
});
}
else if(this.ruleForm.loginName==""){
this.$message({
message: '请输入账户!!!',
type: 'error'
});
}
else if(this.ruleForm.name==""){
this.$message({
message: '请输入昵称!!!',
type: 'error'
});
}
else if(this.ruleForm.password==""){
this.$message({
message: '请输入密码!!!',
type: 'error'
});
}
这个没什么好解释的,就是很简单的验证
如果使用的是组件的表单(比如:element之类的)也可以编辑相应的表单验证方法(规则)
当然,自己手写也没什么问题
补充:数据库建表
(前面好像一直都忘了)
