Question

我正在尝试使用Guzzle，但我收到以下致命错误：

致命错误：未找到类'GuzzleHttp \ ClientInterface' 第13行/var/www/myapp/vendor/guzzlehttp/guzzle/src/functions.php

我正在使用composer autoloader进行自动加载：

require 'vendor/autoload.php';

use Guzzle\Http\Client;

$client = new Client();

$requests = Array(
    $client->createRequest('GET', 'ams1.myapp.com:8080/api/ffmpeg_make_snapshots.php'),
    $client->createRequest('GET', 'ams2.myapp.com:8080/api/ffmpeg_make_snapshots.php'),
    $client->createRequest('GET', 'ams3.myapp.com:8080/api/ffmpeg_make_snapshots.php')
);

$client->sendAll($requests);

发生了什么事？

修改

我的composer.json：

{
    "require": {
        "guzzlehttp/guzzle": "~4"
    }
}

guzzle 4的命名空间是GuzzleHttp，在guzzle 3中，命名空间只是Guzzle。

composer.json：

{
    "require": {
        "guzzlehttp/guzzle": "~4"
    }
}

应该允许您运行以下的PHP脚本：

require 'vendor/autoload.php';

use GuzzleHttp\Client;

$client = new Client();

$requests = Array(
    $client->createRequest('GET', 'ams1.myapp.com:8080/api/ffmpeg_make_snapshots.php'),
    $client->createRequest('GET', 'ams2.myapp.com:8080/api/ffmpeg_make_snapshots.php'),
    $client->createRequest('GET', 'ams3.myapp.com:8080/api/ffmpeg_make_snapshots.php'),
);

$client->sendAll($requests);

如果自动加载器在更改命名空间后仍然失败，则可能是您的作曲家版本已过期且无法识别PSR4自动加载。如果vendor/composer/autoload_psr4.php中没有文件，请尝试执行composer self-update后跟composer dump-autoload以查看问题是否已解决。

Composer自动加载器未加载GuzzleHttp \ ClientInterface
