微信小程序 自动登陆PHP源码实例

app.js

•     初始化APP自动登陆
•     您也可以在任何地方进行用户登陆验证 
•     用法：首先在js文件中定义 var app = getApp(); app.getUserDataToken();
  

App({
 onLaunch: function () {
  
  this.getUserDataToken();
 },
 getUserDataToken:function(){
   var that = this;
   //获取用户缓存token 此token是服务器作为用户唯一验证的标识，具体请看后端代码
   var utoken=wx.getStorageSync("utoken");
    wx.login({
     success: function (res) {
      var code=res.code;
      wx.getUserInfo({
success: function (res) {
 wx.request({
  //用户登陆URL地址，请根据自已项目修改
  url: 'https://66018954.qcloud.la/WxApp/index.php/UserApi/userAuthSlogin',
  method:"POST",
  data: {
    utoken:utoken,
    code: code,
    encrypteddata:res.encryptedData,
    iv:res.iv
  },
  fail:function(res){
  },
  success: function(res) {
   var utoken=res.data.utoken;
   //设置用户缓存
   wx.setStorageSync("utoken",utoken);
  }
 })
}
      })
     }
   })
 }
})

php代码：

public function userAuthSlogin(){
    $content = file_get_contents ( 'php://input' );
    $content=json_decode($content,true);
    $utoken=$content["utoken"];
    if(!empty($utoken)&&S($utoken)){
      $result["success"]=1;
      $result['utoken']=$utoken;
      echo json_encode($result);
      exit();
    }
    $code=$content["code"];
    $encryptedData=$content["encryptedData"];
    $iv = $content['iv'];
    
    $s_result=$this->getSession($code);
    $WxData = new WXBizDataCrypt($s_result['appid'],$s_result['session_key']);
    
    $errCode = $WxData->decryptData($encryptedData, $iv, $user_data);
    $wxap_key = md5(uniqid(md5(microtime(true)),true));
    $result=array();
    if($errCode==0){
      $user_data=json_decode($user_data,true);
      $result["success"]=1;
      $result['utoken']=$wxap_key;
      $user_id = $this->wxUserAdd($user_data);
      if($user_id < 1 || empty($user_id)){
 $result["success"]=-1;
 $result['errCode']=0;
 $result['msg']="获取用户信息出错！";
 echo json_encode($result);
 exit();
      }
      $user_data['uid']=$user_id;
      S($wxap_key,$user_data,7200);
      echo json_encode($result);
      exit();
    }else{
      $result["success"]=-1;
      $result['errCode']=$errCode;
      $result['msg']="获取用户信息出错！";
      echo json_encode($result);
      exit();
    }
  }
