为什么我收到致命错误:未捕获的异常“GuzzleHttp异常客户端异常”，并显示消息“客户端错误:404” - Why I get Fatal error: Uncaught exception 'GuzzleHttpExceptionClientException' with message 'Client error: 404'?

Why I get Fatal error: Uncaught exception 'GuzzleHttpExceptionClientException' with message 'Client error: 404'?

我尝试捕获异常，但我仍然收到"致命错误：未捕获的异常'GuzzleHttp''Exception''ClientException'，并在C：''OS''OpenServer''domains''kinopoisk''parser''php''vendor''guzzlehttp''guzzle''src''Middleware.php：69中收到消息"客户端错误：404">

 <?php
    ini_set('display_errors', 'on');
    error_reporting(E_ALL);
    set_time_limit(0);
    require "vendor/autoload.php";
    use GuzzleHttp'Client;
    use Psr'Http'Message'ResponseInterface;
    use GuzzleHttp'Exception'RequestException;
    use GuzzleHttp'Exception'ClientException;
    $filmsUrl = [297, 298];
    $urlIterator = new ArrayObject($filmsUrl);
    $client = new Client([
        'base_uri' => 'http://example.com',
        'cookies' => true,
    ]);
    foreach ($urlIterator->getIterator() as $key => $value) {
        try {
            $promise = $client->requestAsync('GET', 'post/' . $value, [
                'proxy' => [
                    'http'  => 'tcp://216.190.97.3:3128'
                ]
            ]);
            $promise->then(
                function (ResponseInterface $res) {
                    echo $res->getStatusCode() . "'n";
                },
                function (RequestException $e) {
                    echo $e->getMessage() . "'n";
                    echo $e->getRequest()->getMethod();
                }
            );
        } catch (ClientException $e) {
            echo $e->getMessage() . "'n";
            echo $e->getRequest()->getMethod();
        }
    }
    $promise->wait();

我的代码中有什么问题？

我不确定，但你只在这里抓住ClientException。也试着抓住RequestException。查看Middleware.php:69中使用的异常类的代码，但是如果要捕获所有异常，则需要选择最抽象的异常类，它应该是 RuntimeException或GuzzleException.

尝试这样的事情：

try {
    // your code here
} catch (RuntimeException $e) {
    // catches all kinds of RuntimeExceptions
    if ($e instanceof ClientException) {
        // catch your ClientExceptions
    } else if ($e instanceof RequestException) {
        // catch your RequestExceptions
    }
}

或者您可以尝试以下方法

try {
    // your code here
} catch (ClientException $e) {
    // catches all ClientExceptions
} catch (RequestException $e) {
    // catches all RequestExceptions
}

希望有帮助。

<?php
  
  //some code
  
  try {
    $promise->wait();
  } catch (RequestException $e) {
    echo $e->getMessage();
  }

在 guzzlehttp requestasync 方法中，HTTP 请求是在调用 wait 方法时启动的，而不是在调用 requestasync 方法或 then 方法时启动的。因此，您需要在等待方法中添加 try catch
