很抱歉，如果这是重复的，但我发现的几个关闭问题对我没有用。我是 Laravel 新手。我正在尝试使用 github 库 https://github.com/google/google-api-php-client使用 laravel 5.6 框架。

我通过运行安装了 api:

Composer 需要 google/apiclient:^2.0

我的 composer.json 看起来是正确的，因为它包括:

"require": {
    "php": "^7.1.3",
    "fideloper/proxy": "^4.0",
    "google/apiclient": "^2.2",
    "laravel/framework": "5.6.*",
    "laravel/tinker": "^1.0"
},

我已经运行了 composer update。我可以在供应商的文件夹中看到 Google 文件夹。

github 自述文件然后说要添加自动加载器包含。但是，根据我的理解，这不是我们为 Laravel 做的方式。我发现 Google_Client 类没有命名空间，所以我不知道如何将它正确添加到 app.php 文件中。或者在我想要的 Controller 中使用它。当我尝试在 Controller 中创建一个新的 Google_Client 时，它说找不到。如果我尝试“使用”它，我不知道在没有命名空间的情况下给它什么路径。

编辑以添加以下评论的更多信息:

我运行'composer require google/apiclient:^2.0

它不是它发现的包之一 - 我认为它应该是。我的 composer.json 文件如下所示:

    "preferred-install": "dist",
    "sort-packages": true,

当我运行程序并调用新的 Google_Client 时，我看到了

所以我错过了让自动加载器发现它的一些东西。
运行命令 'composer dumpautoload' 给我:

vagrant@homestead:~/code/sageAnalytics$ composer dumpautoload

生成优化的自动加载文件

Illuminate\Foundation\ComposerScripts::postAutoloadDump @php artisan package:discover Discovered Package: fideloper/proxy Discovered Package: laravel/scout Discovered Package: laravel/tinker Discovered Package: nunomaduro/collision Package manifest generated successfully.

所以再次没有提到包 google/apiclient。我怎样才能找到它？

最佳答案

如果一个类不在任何命名空间中，您可以通过在命名空间内添加前缀 \ 来引用它，如 $foo = new\Google_Client;

同时，您在 use 语句中指定的字符串本身并不是“路径”，它只是“完全限定类名”，即类名及其命名空间包括在前面。所以对于没有命名空间的类，它只是名称，use Google_Client;

关于php - 没有命名空间时如何在 laravel 5.6 上使用 google-api-php-client，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49639801/
