Question

在AWS PHP SDK的第2版中，我只需执行以下操作即可设置请求和响应信息的记录：

<?php
use Monolog\Logger;
use Guzzle\Log\MonologLogAdapter;
use Guzzle\Plugin\Log\LogPlugin;
use Aws\S3\S3Client;
$monolog = new Logger('main');
$monolog_adapter = new MonologLogAdapter($monolog);
$log_plugin = new LogPlugin($monolog_adapter);
$s3_client = S3Client::factory(['region' => 'us-east-1']);
$s3_client->addSubscriber($log_plugin);
var_dump($s3_client->doesObjectExist('my-bucket', 'object-that-doesnt-exist'));

# This is the log entry I want in the v3 version:
# [2015-10-30 14:47:20] main.ERROR: myhostname aws-sdk-php2/2.8.20 Guzzle/3.9.3 curl/7.43.0 PHP/5.5.23 - [2015-10-30T14:47:20+00:00] "HEAD /my-bucket/object-that-doesnt-exist HTTP/1.1" 404  ...
# bool(false)

在第3版中，我似乎无法找到解决方案。中间件似乎没有帮助，因为它们只在发送请求之前触发，因此我无法访问响应HTTP代码。

Guzzle v6在其中间件中内置了此功能，但我不知道如何使用aws-php-sdk。 https://github.com/guzzle/guzzle/blob/master/src/Middleware.php#L180

我最接近的是：

<?php
use Monolog\Logger;
use GuzzleHttp\MessageFormatter;
use GuzzleHttp\Middleware;
use GuzzleHttp\HandlerStack;
use Aws\S3\S3Client;
$monolog = new Logger('main');
$guzzle_formatter = new MessageFormatter(MessageFormatter::CLF);
$guzzle_log_middleware = Middleware::log($monolog, $guzzle_formatter);
$guzzle_stack = HandlerStack::create();
$guzzle_stack->push($guzzle_log_middleware);
$s3_client = new S3Client([
    'region' => 'us-east-1',
    'version' => '2006-03-01',
    'http_handler' => $guzzle_stack,
]);
var_dump($s3_client->doesObjectExist('my-bucket', 'object-that-doesnt-exist'));

# [2015-10-30 15:10:12] main.INFO: myhostname aws-sdk-php/3.9.2 - [30/Oct/2015:15:10:12 +0000] "HEAD /my-bucket/object-that-doesnt-exist HTTP/1.1" 404  [] []
# bool(true)

但是，当日志记录工作时，doesObjectExist（）现在返回不正确的值，因为这个处理程序不会抛出404，aws-php-sdk期望发生异常。其他一些简单的请求，比如上传到S3似乎乍一看似乎有效。不确定此方法可能存在哪些问题。

SDK中使用的处理程序与Guzzle中使用的处理程序略有不同。你正确地创建了一个Guzzle处理程序，并将它传递给SDK，你需要创建一个这样的适配器：

<?php

use Aws\Handler\GuzzleV6\GuzzleHandler;
use Aws\S3\S3Client;
use Monolog\Logger;
use GuzzleHttp\Client;
use GuzzleHttp\MessageFormatter;
use GuzzleHttp\Middleware;
use GuzzleHttp\HandlerStack;

$guzzle_stack = HandlerStack::create();
$guzzle_stack->push(Middleware::log(
    new Logger('main'), 
    new MessageFormatter(MessageFormatter::CLF)
));

$handler = new GuzzleHandler(new Client(['handler' => $guzzle_stack]));

$s3_client = new S3Client([
    'region' => 'us-east-1',
    'version' => '2006-03-01',
    'http_handler' => $handler,
]);

var_dump($s3_client->doesObjectExist('my-bucket', 'object-that-doesnt-exist'));

GuzzleHandler对象将HTTP错误转换为异常。
