本文主要是介绍微信小程序的登录和注册-前后端交互（springboot)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

<form bindsubmit='loginForm'>
  <input type='text' name='accountNumber' placeholder="请输入账号" value=""></input>
  <input type='password' name='password' placeholder="请输入密码" value=""></input>
  <view class='ligin-button'>
    <button formType="submit" type='primary'>点击提交</button>
    <view style="margin-top: 30px;"></view>
    <button formType="reset" type='primary'>重置数据表单</button>
  </view>
</form>

 data: {
    DataList:{
      accountNumber:'',
      password:''
    }
  },
  loginForm: function(data) {
    console.log(data.detail.value)
    //数据的双向绑定;
    this.setData({
      'DataList.accountNumber':data.detail.value.accountNumber,
      'DataList.password': data.detail.value.password
    })
    // this.data.DataList.accountNumber = data.detail.value.accountNumber;
    // this.data.DataList.password = data.detail.value.password;
    wx.request({
      url: 'http://localhost:8080/login',
      method: 'POST',
      header: { 'Content-Type': 'application/x-www-form-urlencoded' },
      data:this.data.DataList,
      success(res){
        console.log("请求成功！"+JSON.stringify(res.data));
        //==='{}' 用于判断js对象是否为空;
        if(JSON.stringify(res.data)==='{}'){
          wx.navigateTo({
            url: '/pages/login/login',
          })
        }
        else{
          wx.navigateTo({
            url: '/pages/main/main',
          })
        }
        // JSON.stringify()此方法将后端传过来的list集合对象转换成json格式。
        // 若不写则将显示[object,object]
      },
      fail(res){
        console.log("请求失败！");
      }
    })
  },

后端的接口调用如下：

package com.aynu.handler;

import com.aynu.beans.People;
import com.aynu.service.ILoginService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
@CrossOrigin
public class LoginController {
    @Autowired
    private ILoginService iLoginService;

    @RequestMapping("login")
    public People JudgeLogin(People people) {
        System.out.println(people.getAccountNumber()+"<----->"+people.getPassword());
//        String accountNumber = people.getAccountNumber();
//        String password = people.getPassword();
        People people2 = iLoginService.JudgeLogin(people);
        System.out.println("people2="+people2);
        if(people2!=null) return people2;
        else return null;
    }
}
