我想从服务器(使用laravel)向客户端(使用java)发送广播消息。
我正在使用什么
我在服务器端完成的操作
.env
文件中配置了Pusher凭据。App\Providers\BroadcastServiceProvider::class
文件中未注释的config/app.php
行。config/auth.php
文件中,我添加了以下内容:'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'devices' => [
'driver' => 'session',
'provider' => 'devices',
],
'api' => [
'driver' => 'passport',
'provider' => 'devices',
],
],
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\User::class,
],
// using devices table to authenticate over api guard
'devices' => [
'driver' => 'eloquent',
'model' => App\Device::class,
],
],
App\Providers\BroadcastServiceProvider
类中,我向boot()
函数添加了以下内容:Broadcast::routes(['prefix' => 'api', 'middleware' => 'auth:api']);
routes/channels.php
中,我添加了以下内容:Broadcast::channel('device.{device_id}', function ($device, $device_id) {
return $device->id === $device_id;
});
AdvertisementAdded
创建事件php artisan make:event AdvertisementAdded
,添加implements ShouldBroadcast
,然后将以下内容添加到其broadcastOn()
方法中:return new PrivateChannel('device.'.$this->device_id);
我在客户端所做的事情
因为我现在正在测试,所以我通过发送邮递员的登录请求获得了access_token
和device_id
我将该accessToken复制到我的Java客户端,并将其存储为accessToken
到String
变量中,这是代码:
String accessToken = "Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6ImY3ZTVlMTAzZWE3MzJjMTI5NzY1YTliMmMzOTM0N2ZhOGE4OTU5MjRjNDA5ZjgyOTA4ZDg5NTFjZTBkOGZlNTA2M2M1YTI1MDBlOTdhZDdiIn0.eyJhdWQiOiIxIiwianRpIjoiZjdlNWUxMDNlYTczMmMxMjk3NjVhOWIyYzM5MzQ3ZmE4YTg5NTkyNGM0MDlmODI5MDhkODk1MWNlMGQ4ZmU1MDYzYzVhMjUwMGU5N2FkN2IiLCJpYXQiOjE1NTkwOTYyNDgsIm5iZiI6MTU1OTA5NjI0OCwiZXhwIjoxNTkwNzE4NjQ3LCJzdWIiOiI3Iiwic2NvcGVzIjpbXX0.FKeE9Z-wv2yUNQPl-qsbu9baYGTdbQ6DuzaI1R8azR6l1CIP9uRI4hCaoWvgx0GXWWLPRNhfQl-YD3KP2YOraW16-h4ie_95B9VQrpFxXnlqKojsfh1xSrSNSl5HncslMWQPVjoesBpM5y_cpG19PGgu-SWo0W6s9Fiz_Nm70oyyZB9mSqU8PVQvAOSNr6TMR0aC3iMLFfkyZkTSwj8EoRyD2LGW6v4PFriqx8JLbZASCOiUYBlYnunWrTFDOAenZcoa5Sw7u7kbSvYehjDKRwKjQM6zmPfi0A3Mp0CHjHE599OXb-NG2IMH-wmlT0vEZjP2U97hxmsNW1RtHNXWaRKFL9T-WVmZbJf3fH5hXqTv495L3MQfq_m5YFHyc5NuIqK4K4xMJB956a33ICnH8DmvPmJgderNAhqEX1JHUAsR63K7xbZxRBDS8OlQYcEf-_v75X0kT1s067enSvI8Vs212AVnI6k0FmgQNM8DfJUq6YduD0m2F2ZWpKPrwdd6PdW5ZlZTEv-D8dYIEQ_CwOWohNoENATmTqxDpPBxK5c723MEt8S7Sa9MEGAo56HW3-9pbazbEdY1GqPWKVkov7K_6eBFcWsV67AgJpoKFt6RiBfRvokgiH96WG89qBB_Ucpm8uBahX93FaOXhVLW0VjJH2LQKrGw0bb5LS8Ql5o";
String deviceId = "7";
Map<String, String> authHeaders = new HashMap();
authHeaders.put("Authorization", accessToken);
HttpAuthorizer authorizer = new HttpAuthorizer("http://localhost:8000/api/broadcasting/auth");
authorizer.setHeaders(authHeaders);
PusherOptions options = new PusherOptions();
options.setAuthorizer(authorizer).setCluster(PUSHER_CLUSTER);
Pusher pusher = new Pusher(PUSHER_APP_KEY, options);
pusher.subscribePrivate("private-device." + deviceId, new PrivateChannelEventListener() {
@Override
public void onEvent(String channelName, String eventName, final String data) {
System.out.println(String.format("Received event on channel [%s]", channelName));
}
@Override
public void onSubscriptionSucceeded(String string) {
System.out.println(String.format("Subscribed to channel [%s]", string));
}
@Override
public void onAuthenticationFailure(String string, Exception excptn) {
System.out.println(string);
}
});
pusher.connect(new ConnectionEventListener() {
@Override
public void onConnectionStateChange(ConnectionStateChange change) {
System.out.println("State changed to " + change.getCurrentState() +
" from " + change.getPreviousState());
}
@Override
public void onError(String message, String code, Exception e) {
System.out.println("There was a problem connecting!");
}
});
// Keeping main thread alive
while (true) {
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
运行上面的代码时,它将在控制台上输出以下内容:
State changed to CONNECTING from DISCONNECTED
State changed to CONNECTED from CONNECTING
java.io.IOException: Server returned HTTP response code: 403 for URL: http://localhost:8000/api/broadcasting/auth
我确定auth:api
中间件正在按我的期望在其他请求上正常工作。
这是我的routes/api.php
的摘录:
Route::middleware('auth:api')->group(function () {
Route::prefix('advertisements')->group(function () {
Route::get('/request', 'AdvertisementsController@getDeviceAdvertisements')
->name('advertisements.getDeviceAdvertisements');
});
});
这是从邮递员到该路由的测试(具有与上述相同的访问令牌):
这是从邮递员到api/broadcasting/auth
路由的测试(具有与上述相同的访问令牌):
出什么问题了?为什么auth:api
中间件下的所有api路由都能正常工作,但api/broadcasting/auth
路由却不能正常工作?
注意
我尝试与公共渠道合作,没有问题。
答案 0 :(得分:0)
经过一整天的搜索,终于解决了。
错误发生在授权频道时,而不是在使用auth:api
中间件对请求进行身份验证时。
我在routes/channels.php
中的私人频道授权功能始终返回false
,这意味着它将拒绝对private-device.{device_id}
频道的所有订阅请求:
Broadcast::channel('device.{device_id}', function ($device, $device_id) {
// this always return false, because of inequality of types
return $device->id === $device_id;
});
上面的授权函数总是返回false
,因为$device->id
(属于int
类型)和$device_id
(属于{{1类型)之间的类型不相等}}。
因此,为了解决该问题,我将它们都强制转换为string
,然后检查是否相等。
这是我用来解决问题的代码:
int
