我使用web推送库发送推送通知 https://github.com/web-push-libs/web-push-php

我在尝试发送推送通知时遇到内部错误

Apache错误日志抛出:

第41行,参考: http://localhost/PWA/web-push-php-example/src/

17:22:36[错误]20232#20232:*46 FastCGI在stderr中发送:“PHP /var/www/html/PWA/web push php示例/vendor/minishlink/web push/src/Subscription.php 第69行PHP消息:PHP致命错误:未捕获类型错误:参数在中调用的类型字符串为null /var/www/html/PWA/web push php示例/vendor/minishlink/web push/src/Subscription.php 第72行,定义见 /var/www/html/PWA/web push php示例/vendor/minishlink/web push/src/Subscription。php:39 堆栈跟踪:抛出上游:“fastcgi://unix:/run/php/php7.2-fpm.sock:“,主机: “localhost”,推荐人: " https://localhost/PWA/web-push-php-example/src/

PHP代码:

<?php
require __DIR__ . '/../vendor/autoload.php';
use Minishlink\WebPush\WebPush;
use Minishlink\WebPush\Subscription;

// here I'll get the subscription endpoint in the POST parameters
// but in reality, you'll get this information in your database
// because you already stored it (cf. push_subscription.php)
$sub =json_decode(file_get_contents('php://input'), true);
$sub_endpoint =$sub['endpoint'];
$sub_publicKey =$sub['publicKey'];
$sub_authToken =$sub['authToken'];
$sub_contentEncoding =$sub['contentEncoding'];
$notifications = [
    [
        'subscription' => Subscription::create([            
            'endPoint' => $sub_endpoint,
            'publicKey' => $sub_publicKey,            
            'authToken' => $sub_authToken,            
            'contentEncoding' => $sub_contentEncoding, // one of PushManager.supportedContentEncodings
        ]),
        'payload' => '{msg:"test"}',
    ],
];

$auth = array(
    'VAPID' => array(

    ),
);
$defaultOptions = array(
    'TTL' => 300, // defaults to 4 weeks
    'urgency' => 'normal', // protocol defaults to "normal"
    'topic' => 'push', // not defined by default - collapse_key
);

$webPush = new WebPush($auth, $defaultOptions);

// send multiple notifications with payload

$webPush->flush();

// send one notification and flush directly
$webPush->sendNotification(
    $notifications[0]['subscription'],
    $notifications[0]['payload'], // optional (defaults null)
    true // optional (defaults false)

@Harish,构造函数“?”应该可以在PHP 7.1版中使用。我发现你的参数值有错误。

__construct()必须是/var/www/html/PWA/web-push-php-example/vendor/minishlink/web-push/src/Subscription.php中调用的字符串类型,为null

由于错误日志指示端点值作为null传递,因此应该将其作为字符串值传递。

在通知中传递的变量 终结点 .

https://github.com/web-push-libs/web-push-php/blob/master/src/Subscription.php#L41-L43

从3v4l代码可以看出,它适用于7.1以上的所有版本:

<?php
class X
{
    public function __construct(
        string $endpoint,
        ?string $publicKey = null,
        ?string $authToken = null,
        ?string $contentEncoding = null
    ) {
        $this->endpoint = $endpoint;

    }
}

$x = new X('blah', 'blahblah');

https://3v4l.org/A1XeN

代码的所有v5迭代都会产生错误:

Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE) in /in/A1XeN on line 6
