今天首先是完成了阶段作业中，注册和登录时的输入字符的限制，这样也可以解决很多后续出错的可能。
regis.setOnClickListener(new View.OnClickListener() {
@SuppressLint("SetTextI18n")
@Override
public void onClick(View v) {
if(username_v.getText().toString().isEmpty())
{
message_v.setText("用户名不能为空");
return;
}
if (username_v.getText().toString().length()>20)
{
message_v.setText("用户名长度超过最大限制（20）");
return;
}
if(name_v.getText().toString().isEmpty())
{
message_v.setText("姓名不能为空");
return;
}
if (name_v.getText().toString().length()>20)
{
message_v.setText("姓名长度超过最大限制（20）");
return;
}
if(phone_v.getText().toString().isEmpty())
{
message_v.setText("电话号码不能为空");
return;
}
if(phone_v.getText().toString().length()!=11)
{
message_v.setText("电话号码格式不正确");
return;
}
if (user_class_v.getText().toString().length()>20)
{
message_v.setText("班级长度超过最大限制（20）");
return;
}
if(user_class_v.getText().toString().isEmpty())
{
message_v.setText("班级不能为空");
return;
}
if (password_v.getText().toString().length()>20)
{
message_v.setText("密码长度超过最大限制（20）");
return;
}
if(password_v.getText().toString().isEmpty())
{
message_v.setText("密码不能为空");
return;
}
if(password2_v.getText().toString().isEmpty())
{
message_v.setText("确认密码不能为空");
return;
}
if(!password_v.getText().toString().equals(password2_v.getText().toString()))
{
message_v.setText("两次密码不一致");
return;
}
confirm();
}
});
之后就是再次尝试vue来连接后端spring boot，
初步学会使用js的api来完成异步获取。

//定制请求的实例

const baseURL = '/api';

const instance = axios.create({baseURL})
//添加响应拦截器
instance.interceptors.response.use(
