[PHP知识库]小程序登录问题解决(php接口）

php代码

后台判断用户信息，入库操作

   public static function content(){
        $m_id=input('m_id');
        $content=input('content');
        $uid=(new Token)->getUserStatus('id');
        $content=self::sensitive($content);
        if (empty($uid)){
            return json_encode(['code'=>400,'msg'=>"用户状态出错",'data'=>$uid]);
        }else{
            $data=[];
            $data['m_id']=$m_id;
            $data['uid']=$uid;
            $data['content']=$content;
            $user = new MovieModel();
            $user->data($data);
            $res=$user->save();
            if ($res){
                return json_encode(['code'=>200,'msg'=>"评论成功",'data'=>null]);
            }else{
                return json_encode(['code'=>500,'msg'=>"评论失败",'data'=>null]);
            }
        }
    }

js代码

getUserProfile:function() {
      wx.getUserProfile({
        desc: '用户信息',
        success:res=>{
            wx.login({
                success:e=>{
                   if(e.code){
                      wx.request({
                        url: '',
                        data:{
                            code:e.code,
                            nickname:res.userInfo.nickName,
                            avatar:res.userInfo.avatarUrl
                        },
                        success:result=>{
                          wx.setStorageSync('userInfo',result.data.data,'3600*24*6');
                          wx.setStorageSync('token',result.data.token,'3600*24*6');
                          wx.navigateBack({
                            delta: 1
                          })
                        }
                      })
                   }else{
                       console.log('登陆失败'+res.errMsg)
                   }
                }
            })
           
        }
      })
  },

验证用户（php)

public static function getUserStatus($key){
        $token=\think\Request::instance()->header('token');
        $user=\think\Cache::get($token);
        if (is_object($user)){
            $user=$user->toArray();
        }
        $data=$user[$key];
        return $data;
    }

简单说实现微信小程序的登录其实很简单，大家要合理使用噢！
