  </view>
 </view>
</view>

2、js文件

"use strict";
 
Object.defineProperty(exports, "__esModule", {
 value: true
});
exports.default = Page({
 data: {
  name: "",
  pass: "",
  isname: false,
  ispass: false
 },
 ureg: function ureg() {
  wx.navigateTo({
   url: "./../user/reg"
  });
 },
 tlogin: function tlogin() {
  wx.navigateTo({
   url: "./../tlogin/tlogin"
  });
 },
 username: function username(e) {
  this.setData({ name: e.detail.value });
 },
 password: function password(e) {
  this.setData({ pass: e.detail.value });
 },
 submitHandler: function submitHandler() {
  var that = this;
  if (that.data.name == "") {
   wx.showModal({
    title: "错误",
    content: "用户名不能为空"
   });
   that.isname = false;
  } else {
   that.isname = true;
  }
  if (that.data.pass == "") {
   wx.showModal({
    title: "错误",
    content: "密码不能为空"
   });
   that.ispass = false;
  } else {
   that.ispass = true;
  }
  if (that.ispass && that.isname) {
   // 提交
   wx.request({
    url: "http://localhost:8080/Teacher/ulogin.action", //接口地址
    data: {
     username: that.data.name,
     password: that.data.pass
    },
    method: "get",
    header: {
     "content-type": "application/json"
    },
    success: function success(res) {
     var info = res.data;
     if (info == "fail") {
      wx.showModal({
       title: "错误",
       content: "用户名或者密码输入不正确"
      });
     } else {
      //存储数据
      // 同步接口立即写入
      wx.setStorageSync("uname", that.data.name + "");
      wx.setStorageSync("indentity", "user");
      //页面跳转
      //页面跳转
      wx.switchTab({
       url: "/pages/center/center"
      });
      console.log("页面跳转111");
     }
    }
   });
   // 提交
  }
 }
});

3、wxss文件

.frm {
 margin-top: 200rpx;
}

我的后端是用java的ssh框架实现的

package cn.com.service;
import java.io.IOException;
import java.util.List;
import javax.servlet.http.HttpServletResponse;
import net.sf.json.JSONArray;
import org.apache.struts2.ServletActionContext;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.opensymphony.xwork2.ModelDriven;
import cn.com.bean.User;
@Repository(value = "ulogin")
@Scope("prototype")
public class Ulogin implements ModelDriven<User> {
 @Autowired
 private SessionFactory sf;
 @Autowired
 private User u;
 // 注册功能
 @Transactional
 public String regedit() {
 Session session = sf.getCurrentSession();
 session.save(u);
 return null;
 }
 
 // 登录功能
 @Transactional
 public String login() {
 Session session = sf.getCurrentSession();
 String sql = "from User where username=? and password=?";
 Query query = session.createQuery(sql);
 query.setString(0, u.getUsername());
 query.setString(1, u.getPassword());
 User uu = (User) query.uniqueResult();
 String info = null;
 if (uu != null) {
  info = "success";
 } else {
  info = "fail";
 }
 HttpServletResponse response = ServletActionContext.getResponse();
 response.setCharacterEncoding("utf-8");
 try {
  response.getWriter().write(info);
 } catch (IOException e) {
  e.printStackTrace();
 }
 return null;
 }
 
 @Override
 public User getModel() {
 // TODO Auto-generated method stub
 return u;
 }
}
