PHP 与 Firebase 的连接如何工作？

How does PHP connection to firebase work?

提问by Lyka San Pedro Hementera

If you have the time to read the firebase-phpdocumentation, you can see there how to use the helper library to "connect" to firebase. But unfortunately, I think that the connection could only be established by phpunit, in other words, output can only be seen in the terminal. Since when you run the php pages in your browser, it will return fatal errors. Does anyone know how to use the helper libraryto connect to the firebasedata without using phpunit? Thank you in advance.

如果您有时间阅读firebase-php文档，您可以在那里看到如何使用帮助程序库“连接”到firebase。但不幸的是，我认为连接只能通过phpunit建立，也就是说，输出只能在终端中看到。因为当您在浏览器中运行 php 页面时，它会返回致命错误。没有人知道如何使用助手库连接到火力点的数据，而无需使用PHPUnit的？先感谢您。

Using the lib is very easy, when you just look at the source code of the tests.

使用 lib 非常简单，只需查看测试的源代码即可。

There are two kinds of tests:

有两种测试：

• a real functionality test, which uses cURL requests to the server and therefore is slow during testing with PHPUnit
• a mocked functionality test (stub), which simulates the connection to and the response from the server, which is faster during testing

• 一个真正的功能测试，它使用对服务器的 cURL 请求，因此在使用 PHPUnit 进行测试时速度很慢
• 模拟功能测试（存根），模拟与服务器的连接和来自服务器的响应，在测试过程中速度更快

Now, in order to use firebase-php, you would simply do the same things as in the real functionality test. Include the lib, prepare the connection object with login credentials and then call the method you want. The interfacedescribes, which methods you can expect in the firebaseLib class - or just look at the lib source itself.

现在，为了使用 firebase-php，您只需执行与实际功能测试相同的操作。包括 lib，准备带有登录凭据的连接对象，然后调用所需的方法。该接口描述了您可以在 firebaseLib 类中使用哪些方法 - 或者只是查看lib 源代码本身。

This piece of code should get you started:

这段代码应该让你开始：

require '/path/to/libs/firebase-php/firebaseLib.php';
$url = '...';
$token = '...';
$firebase = new Firebase($url, $token);
$firebase->get('something/from/somewhere');

If you fetch the library via composer, you might declare an autoloading classmap, too. The author hasn't done this, yet.

如果您通过 获取库composer，您也可以声明一个自动加载类映射。作者还没有做到这一点。

{
    "autoload": {
        "classmap": ["vendor/ktamas77/firebase-php/firebaseLib.php"]
    }
}

Then simply require Composer's Autoloader with require "vendor/autoload.php";and new Firebaseto autoload the class.

然后只需要 Composer 的 Autoloader withrequire "vendor/autoload.php";和new Firebase来自动加载类。
