'GuzzleHttp\Collection' 未找到

Question

我正在尝试 use this Google Analytics API tutorial，但这取决于 Guzzle。我收到此错误：

Fatal error: Class 'GuzzleHttp\Collection' not found in ../google-api-php-client/src/Google/Client.php on line 93

但我已经安装了 Guzzle：

>>php composer.phar require guzzlehttp/guzzle:~5.2
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing react/promise (v2.2.1)

  - Installing guzzlehttp/streams (3.0.0)

  - Installing guzzlehttp/ringphp (1.1.0)

  - Installing guzzlehttp/guzzle (5.3.0)

Writing lock file
Generating autoload files

这是我的 composer.json:

"require": {
        "php": ">=5.4",
        "google/auth": "v0.3",
        "monolog/monolog": "^1.17",
        "phpseclib/phpseclib": "~2.0",
        "guzzlehttp/guzzle": "5.3.*"
    },

Answer 1

您必须包含 Composer 的自动加载文件，如下所述：https://getcomposer.org/doc/01-basic-usage.md#autoloading

在您的主文件中，在顶部添加以下行（在需要这些文件的任何代码之前）：

require __DIR__ . '/vendor/autoload.php';
