小編給大家分享一下微信小程序如何實現注冊登錄功能，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
實現效果如下
前端 部分
注冊功能
1、wxml文件

});3、wxss文件
.frm {
margin-top: 200rpx;
}登錄功能
1、wxml文件
<view> <view class="frm"> <view class="ui-row ui-row-border-top ui-row-border-bottom" > <view class="ui-col ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> </view> </view> <view class="ui-col" > <view class="ui-col-content"> <view class="ui-row" > <view class="ui-col ui-col-4 ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> 用戶名 </view> </view> <view class="ui-col ui-col-8 ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> <input name="input" placeholder="請輸入用戶名" bindinput="username"></input> </view> </view> </view> </view> </view> </view> <view class="ui-row ui-row-border-top ui-row-border-bottom" > <view class="ui-col ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> </view> </view> <view class="ui-col" > <view class="ui-col-content"> <view class="ui-row" > <view class="ui-col ui-col-4 ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> 密碼 </view> </view> <view class="ui-col ui-col-8 ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> <input placeholder="設置密碼" password="true" bindinput="password"></input> </view> </view> </view> </view> </view> </view> <view class="ui-row ui-row-border-top ui-row-border-bottom" > <view class="ui-col ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> </view> </view> <view class="ui-col" > <view class="ui-col-content"> <view class="ui-row" > <view class="ui-col ui-col-4 ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> <button type="primary" bindtap="submitHandler">登錄</button> </view> </view> <view class="ui-col ui-col-4 ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> <button bindtap="ureg">用戶注冊</button> </view> </view> <view class="ui-col ui-col-4 ui-col-border-right ui-col-align-center align-center valign-middle" > <view class="ui-col-content align-center valign-middle"> <button bindtap="tlogin">老師登錄</button> </view> </view> </view> </view> </view> </view> </view> </view>
2、js文件
"use strict";
Object.defineProperty(exports, "__esModule", {
value: true
});
exports.default = Page({
data: {

});
} else {
//存儲數據
// 同步接口立即寫入
wx.setStorageSync("uname", that.data.name + "");
wx.setStorageSync("indentity", "user");
//頁面跳轉
//頁面跳轉
wx.switchTab({
url: "/pages/center/center"
});
console.log("頁面跳轉111");
}
}
});
// 提交
}
}
});3、wxss文件
.frm {
margin-top: 200rpx;
}我的后端是用java的ssh框架實現的
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;
// 注冊功能
@Transactional
public String regedit() {
Session session = sf.getCurrentSession();
session.save(u);
return null;
}
// 登錄功能
@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;
}
