接上篇微信小程序后端搭建:分享:Laravel 微信小程序后端搭建 后端搭建好后第一件事就是用户登录认证,简单实现微信小程序登录认证 1.user 模型 use Laravel\Passport\HasApiTokens; 新增 2. 新增一条路由 3. 在 UserController 控制器里新建 function weappLogin (),别忘了 use 这些 写两个 function weappLogin (),avatarUpyun () 微信的头像 / 0 小头像默认 / 132 4. 后端上面就写好了,再看下小程序端怎么做的哈,打开小程序的 app.json,添加 "pages/auth/auth", 5. 打开 auth.js 6. 打开 auth.wxml 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。use HasApiTokens, Notifiable;protected $fillable = [ 'id', 'name', 'email', 'email_verified_at', 'username', 'phone', 'avatar',//我用来把微信头像的/0清晰图片,存到又拍云上 'weapp_openid', 'nickname', 'weapp_avatar', 'country', 'province', 'city', 'language', 'location', 'gender', 'level',//用户等级 'is_admin',//is管理员];
//前端小程序拿到的地址:https://域名/api/v1/自己写的接口Route::group(['prefix' => '/v1'], function () { Route::post('/user/login', 'UserController@weappLogin');});
use App\User;use Carbon\Carbon;use Illuminate\Http\Request;use Illuminate\Support\Facades\Storage;
public function weappLogin(Request $request) { $code = $request->code; // 根据 code 获取微信 openid 和 session_key $miniProgram = \EasyWeChat::miniProgram(); $data = $miniProgram->auth->session($code); if (isset($data['errcode'])) { return $this->response->errorUnauthorized('code已过期或不正确'); } $weappOpenid = $data['openid']; $weixinSessionKey = $data['session_key']; $nickname = $request->nickname; $avatar = str_replace('/132', '/0', $request->avatar);//拿到分辨率高点的头像 $country = $request->country?$request->country:''; $province = $request->province?$request->province:''; $city = $request->city?$request->city:''; $gender = $request->gender == '1' ? '1' : '2';//没传过性别的就默认女的吧,体验好些 $language = $request->language?$request->language:''; //找到 openid 对应的用户 $user = User::where('weapp_openid', $weappOpenid)->first(); //没有,就注册一个用户 if (!$user) { $user = User::create([ 'weapp_openid' => $weappOpenid, 'weapp_session_key' => $weixinSessionKey, 'password' => $weixinSessionKey, 'avatar' => $request->avatar?$this->avatarUpyun($avatar):'', 'weapp_avatar' => $avatar, 'nickname' => $nickname, 'country' => $country, 'province' => $province, 'city' => $city, 'gender' => $gender, 'language' => $language, ]); } //如果注册过的,就更新下下面的信息 $attributes['updated_at'] = now(); $attributes['weixin_session_key'] = $weixinSessionKey; $attributes['weapp_avatar'] = $avatar; if ($nickname) { $attributes['nickname'] = $nickname; } if ($request->gender) { $attributes['gender'] = $gender; } // 更新用户数据 $user->update($attributes); // 直接创建token并设置有效期 $createToken = $user->createToken($user->weapp_openid); $createToken->token->expires_at = Carbon::now()->addDays(30); $createToken->token->save(); $token = $createToken->accessToken; return response()->json([ 'access_token' => $token, 'token_type' => "Bearer", 'expires_in' => Carbon::now()->addDays(30), 'data' => $user, ], 200); } //我保存到又拍云了,版权归腾讯所有。。。头条闹的 private function avatarUpyun($avatar) { $avatarfile = file_get_contents($avatar); $filename = 'avatars/' . uniqid() . '.png';//微信的头像链接我也不知道怎么获取后缀,直接保存成png的了 Storage::disk('upyun')->write($filename, $avatarfile); $wexinavatar = config('filesystems.disks.upyun.protocol') . '://' . config('filesystems.disks.upyun.domain') . '/' . $filename; return $wexinavatar;//返回链接地址 }
