PHP Firebase帮助 - 设置JWT [英] PHP Firebase help - Set up JWT

问题描述

在我的服务器上，我正在运行几个读取我的Firebase实时数据库的PHP文件。根据 Firebase的文档，我需要设置自定义令牌来运行我的 Firebase PHP客户端。 Firebase文档说我需要返回这个;

  return JWT :: encode（$ payload，$ private_key，RS256） ; 
  

我如何引用JWT类？我下载了一个智威汤逊图书馆，但我不知道如何实现这个到我的项目。任何帮助将是伟大的，我主要是一个移动开发人员，并没有什么经验与PHP。

解决方案

firebase / php-jwt库使用作曲家。如果你来自android开发背景，Composer是PHP的依赖管理器，与Java中的Maven类似。你将需要知道如何使用php的require / include函数在php中导入类。您需要一些使用PHP的经验来使用作曲家。

为了使用没有作曲者的firebase / php-jwt库，你可以使用下面的示例代码： jwt文件夹中的库）

$ pre $ $ $
$ b require_once'jwt / src / BeforeValidException .PHP';
require_once'jwt / src / ExpiredException.php';
require_once'jwt / src / SignatureInvalidException.php';
require_once'jwt / src / JWT.php';


使用\Firebase\JWT\JWT;

$ key =example_key;
$ token = array（
iss=>http://example.org，
aud=>http://example.com，
iat=> 1356999524，
nbf=> 1357000000
）;

$ jwt = JWT :: encode（$ token，$ key）;
$ encoded = JWT :: decode（$ jwt，$ key，array（'HS256'））;

print_r（$ decode）;

注意：这将成为一个对象而不是关联数组。要得到

On my server I am running a few PHP files that read my Firebase Realtime Database. According to Firebase's documents I need to set up custom token to get my Firebase PHP Client running. The Firebase document says I need to return this;

  return JWT::encode($payload, $private_key, "RS256");

How exactly do I reference the JWT class? I downloaded a JWT library but I am not sure how to implement this into my project. Any help would be great, I am mainly a mobile developer and have little experience with PHP.

解决方案

firebase/php-jwt library uses composer. Composer is a dependency manager for PHP similar to Maven in java if you come from android development background. You would need to know how to import classes in php using require/include functions of php. You would need some experience with php to use composer.

In order to use firebase/php-jwt library without composer you could use the following sample code: (I downloaded the library inside 'jwt' folder)

<?php

require_once 'jwt/src/BeforeValidException.php';
require_once 'jwt/src/ExpiredException.php';
require_once 'jwt/src/SignatureInvalidException.php';
require_once 'jwt/src/JWT.php';


use \Firebase\JWT\JWT;

$key = "example_key";
$token = array(
   "iss" => "http://example.org",
   "aud" => "http://example.com",
   "iat" => 1356999524,
   "nbf" => 1357000000
);

/**
 * IMPORTANT:
 * You must specify supported algorithms for your application. See
 * https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
 * for a list of spec-compliant algorithms.
*/
$jwt = JWT::encode($token, $key);
$decoded = JWT::decode($jwt, $key, array('HS256'));

print_r($decoded);

/*
 NOTE: This will now be an object instead of an associative array. To get
 an associative array, you will need to cast it as such:
*/

$decoded_array = (array) $decoded;

/**
* You can add a leeway to account for when there is a clock skew times   between
* the signing and verifying servers. It is recommended that this leeway should
* not be bigger than a few minutes.
*
* Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef
*/
   JWT::$leeway = 60; // $leeway in seconds
   $decoded = JWT::decode($jwt, $key, array('HS256'));
 ?>
