Question

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

尝试发送通知时出现内部错误

我检查了两个PHP版本：7.1.22,7.2.9-1
Apache错误日志抛出：

[：error] [客户端:: 1：33302] PHP解析错误：语法错误，意外 '？'，期望变量（T_VARIABLE）在 /PWA/web-push-php-example/vendor/minishlink/web-push/src/Subscription.php 在第41行，引荐来源：http://localhost/PWA/web-push-php-example/src/

我也在Ngnix /错误日志中尝试过：

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(
        'subject' => 'mailto:me@website.com', // can be a mailto: or your website address
        'publicKey' => 'BCmti7ScwxxVAlB7WAyxoOXtV7J8vVCXwEDIFXjKvD-ma-yJx_eHJLdADyyzzTKRGb395bSAtxlh4wuDycO3Ih4', // (recommended) uncompressed public key P-256 encoded in Base64-URL

        //'pemFile' => './keys/private_key.pem' // if you have a PEM file and can link to it on your filesystem        
    ),
);
$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)
);

Answer 1

您完全确定自己实际上在运行PHP 7.21或7.2吗？问题是这里的构造函数中的问号：

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

从3v4l代码可以看到，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

Answer 2

@Harish，构造函数'？'应该从PHP 7.1版本开始工作。我发现您的参数值有误。

__ construct（）必须为字符串类型，给定为null，在/ var / www / html / PWA / web-push-php-example / vendor / minishlink / web-push / src / Subscription中调用。 php

由于错误日志指示端点值以null值传递，因此应将其以字符串值形式传递。

您在通知中以 endPoint 传递的变量，但在lib中它被分配为 endpoint 。
