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
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 ];
2. 新增一条路由
//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’); });
3. 在 UserController 控制器里新建 function weappLogin (),别忘了 use 这些
use App\User; use Carbon\Carbon; use Illuminate\Http\Request; use Illuminate\Support\Facades\Storage;
写两个 function weappLogin (),avatarUpyun ()
public function weappLogin(Request $request) { $code = $request->code; // 根据 code 获取微信 openid 和 session_key $miniProgram = \EasyWeChat::miniProgram(); $data = miniProgram−>auth−>session(miniProgram->auth->session(miniProgram−>auth−>session(code); if (isset($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?request−>country?request->country:‘’; $province = request−>province?request->province?request−>province?request->province:‘’; $city = request−>city?request->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?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(!weappOpenid)->first(); //没有,就注册一个用户 if (!weappOpenid)−>first();//没有,就注册一个用户if(!user) { $user = User::create([ ‘weapp_openid’ => $weappOpenid, ‘weapp_session_key’ => $weixinSessionKey, ‘password’ => $weixinSessionKey, ‘avatar’ => request−>avatar?request->avatar?request−>avatar?this->avatarUpyun($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(avatar; if (avatar;if(nickname) { $attributes[‘nickname’] = KaTeX parse error: Expected 'EOF', got '}' at position 11: nickname; }̲ if (request->gender) { $attributes[‘gender’] = $gender; } // 更新用户数据 user−>update(user->update(user−>update(attributes); // 直接创建token并设置有效期 $createToken = user−>createToken(user->createToken(user−>createToken(user->weapp_openid); createToken−>token−>exp<bstyle="color:transparent">来源gao@dai!搞createToken->token->exp<b style="color:transparent">来源gao@dai!搞createToken−>token−>exp<bstyle="color:transparent">来源gao@dai!搞代^码网ires_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’ => KaTeX parse error: Expected 'EOF', got '}' at position 16: user, ], 200); }̲ //我保存到又拍云了,版权归…avatar) { avatarfile=filegetcontents(avatarfile = file_get_contents(avatarfile=filegetcontents(avatar); filename=′avatars/′.uniqid().′.png−600′;//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 = 'avatars/' . uniqid() . '.png-600';//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=′avatars/′.uniqid().′.png−600′;//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 }
微信的头像 / 0
小头像默认 / 132
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”,
{ “pages”: [ “pages/index/index”, “pages/auth/auth”,//做一个登录页面 “pages/logs/logs” ], “window”: { “backgroundTextStyle”: “light”, “navigationBarBackgroundColor”: “#fff”, “navigationBarTitleText”: “WeChat”, “navigationBarTextStyle”: “black” }, “sitemapLocation”: “sitemap.json”, “permission”: { “scope.userLocation”: { “desc”: “你的位置信息将用于小程序位置接口的效果展示” } } }
5. 打开 auth.js
const app = getApp(); Page({ /** * 页面的初始数据/ data: { UserData: [], isClick: false, }, /* * 生命周期函数–监听页面加载 */ onLoad: function(options) { }, login: function(e) { let that=this that.setData({ isClick: true }) wx.getUserInfo({ lang: “zh_CN”, success: response => { wx.login({ success: res => { let data = { code:res.code, nickname: response.userInfo.nickName, avatar: response.userInfo.avatarUrl, country: response.userInfo.country ? response.userInfo.country : ‘’, province: response.userInfo.province ? response.userInfo.province : ‘’, city: response.userInfo.city ? response.userInfo.city : ‘’, gender: response.userInfo.gender ? response.userInfo.gender : ‘’, language: response.userInfo.language ? response.userInfo.language : ‘’, } console.log(data) app.globalData.userInfo = data; wx.request({ url: ‘你的后端地址’,//我用的valet,http://ak.name/api/v1/user/login method: ‘POST’, data: data, header: { ‘Content-Type’: ‘application/x-www-form-urlencoded’ }, success: function (res) { console.log(res) if (res.statusCode != ‘200’) { return false; } wx.setStorageSync(‘access_token’, res.data.access_token) wx.setStorageSync(‘UserData’, res.data.data ? res.data.data : ‘’) wx.redirectTo({ url: ‘/pages/index/index’, }) }, fail: function (e) { wx.showToast({ title: ‘服务器错误’, duration: 2000 }); that.setData({ isClick: false }) }, }); } }) }, fail: function (e) { that.setData({ isClick: false }) }, }) } })
6. 打开 auth.wxml
微信登录
