Stripe Webhooks错误503无效编码:ISO-8859-1 [英] Stripe Webhooks Error 503 Invalid encoding: ISO-8859-1

问题描述

我按照Stripe的建议设置了带有签名验证的Stripe Webhook:

I setup a stripe webhook with signature verification just as recommended by stripe:

<?php

logme("Secure connection: ".isSecure());
logme("I was called at:".time());

require 'vendor/autoload.php';

\Stripe\Stripe::setApiKey('sk_test_ff...');
$endpoint_secret = 'whsec_Ky...';

$payload = @file_get_contents('php://input');

if($payload) {
//request body is set
} else {
//request body is not set
    exit();
}

$sig_header = $_SERVER['HTTP_STRIPE_SIGNATURE'];

$event = null;


try {
    $event = \Stripe\Webhook::constructEvent(
        $payload, $sig_header, $endpoint_secret
    );

} catch(\UnexpectedValueException $e) {
    // Invalid payload
    http_response_code(400);
    exit();
} catch(\Stripe\Exception\SignatureVerificationException $e) {
    // Invalid signature
    http_response_code(400);
    exit();
}

http_response_code(200);

// Handle the event
switch ($event->type) {
    case 'event1':
    // do something 
    break;
    
    // ... handle other event types
    default:
        echo 'Received unknown event type ' . $event->type;
        logme('Received unknown event type ' . $event->type);
}


function logme($msg){

    $log_file = "error.txt";
// logging error message to given log file
    error_log($msg."\n-\n", 3, $log_file);
}
function isSecure() {
    return
        (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off')
        || $_SERVER['SERVER_PORT'] == 443;
}

在条纹仪表板上，我使用 https://example.org/path/to创建了一个Webhook./webhook.php ，但是如果我在测试模式下启动invoice.paid webhook，则会收到以下错误消息:

At stripe dashboard I created a webhook with https://example.org/path/to/webhook.php but if I fire invoice.paid webhook in test mode I receive the following error:

Test-Webhook-Error: 503 
Invalid encoding: ISO-8859-1 

有人知道这种错误吗?

更新
它似乎取决于触发的事件的类型.例如.plan.deleted工程不成功，payment_intent.succeeded

Update
It seems to depend on the type of event that is triggered. E.g. plan.deleted works and payment_intent.succeeded does not

推荐答案

此错误似乎不是来自签名验证，而是来自请求/网络堆栈中的其他位置.请注意，您在 try {} 中引发的错误是 withStatus(403)(不是503).您能否从服务器中提供更详细的日志记录，以识别失败的地方?

This error does not appear to be coming from the signature verification, but rather somewhere else in your request/network stack. Note that the error you throw in the try {} is withStatus(403) (not 503). Can you provide more detailed logging from your server to identify where this fails?

请参见此相关问题并将解决方案连接到HTTP->HTTPS重定向.确保您配置的端点直接进入HTTPS，并且您的SSL证书正确响应.

See this related question and the solution being connected to a HTTP -> HTTPS redirect. Ensure your configured endpoint is going directly to HTTPS and that your SSL certificates are responding correctly.

我还看到您在处理程序开始时甚至在签名检查之前都在调用 $ event = $ request-> getParsedBody(); ，这可能会导致被操纵的主体数据出现问题(签名验证需要请求的原始内容.)

I also see you are calling $event = $request->getParsedBody(); at the start of your handler even before signature checking, which can something cause problems with the body data being manipulated (the signature verification requires the raw body of the request).
