使用PHP设置firebase v3自定义身份验证 [英] Setting up firebase v3 custom auth with php

问题描述

我试图根据以下指南，使用来自Google的新的firebase sdk设置自定义身份验证： https：/ /firebase.google.com/docs/auth/server#use_a_jwt_library

在samble代码中，它表示：

lockquote

从JSON密钥文件中获取您的服务帐户的电子邮件地址和私钥

不幸的是我不知道在哪里得到这个json文件。如果我转到我的Firebase控制台（ https://console.firebase.google.com/ ），我设法阻止了一个json文件，但它不包含任何电子邮件地址和私钥。

我设法在我的谷歌云平台控制台中找到包含电子邮件地址和私钥的json文件（ http://console.cloud.google.com ），然后转到API管理器>凭据菜单。令人惊讶的是，我的firebase应用程序显示在那里。我复制并粘贴了电子邮件和密钥到示例代码，然后我得到这个错误：
$ b

警告：openssl_sign（）：提供的关键参数无法强制转换为/volume1/web/yeti/vendor/firebase/php-jwt/src/JWT.php中的私钥，致183线路致命错误：未捕获的异常DomainException带有消息OpenSSL无法签署数据in / volume1 / web / yeti / vendor / firebase / php-jwt / src / JWT.php：185堆栈跟踪：＃0 /volume1/web/yeti/vendor/firebase/php-jwt/src/JWT.php(154）： Firebase \JWT\JWT :: sign（'eyJ0eXAiOiJKV1Q ...'，NULL，'RS256'）＃1 /volume1/web/yeti/jwt.php(21）：Firebase \JWT\JWT :: encode （Array，NULL，'RS256'）＃2 /volume1/web/yeti/jwt.php(24）：create_custom_token（'1234'，false）＃3 {main}抛入/ volume1 / web / yeti / vendor / firebase /php-jwt/src/JWT.php on line 185

有人知道我做错了什么吗？ / p>

谢谢

解决方案

您是否找到解决方案？仍然遇到同样的问题！适用于HS256，不适用于RS256。它是谷歌云类的限制吗？

问题：使用错误的密钥和电子邮件。这些应该在与Firebase项目相对应的Google Cloud凭据部分中生成。

解决方案：

• 转到console.cloud.google.com 。
  
• 选择相关的Firebase项目。


• 然后'API Manager' - >'Credentials'。 >'Create Credentials' - >'Service Account Key' - >选择JSON。
  
• 创建的文件将包含所需的'private_key'&
  
  
  

  
  $ b

  $ service_account_email =

[e-mail];
$ private_key =----- BEGIN私钥----- \\\\\\\\\\\\\\\\\\\\
$ uid ='UserToUseInFirebaseRules';
$ is_premium_account = $ uid;




您不需要在create_custom_token函数中更改任何内容，也可以根据您的需要更改过期日期/时间。



然后调用函数：

$ $ $ codereate_custom_token（$ uid，$ is_premium_account）;





I'm trying to set up custom auth with the new firebase sdk from google following those guidelines : https://firebase.google.com/docs/auth/server#use_a_jwt_library
In the samble code it says :

Get your service account's email address and private key from the JSON key file

Unfortunately I have not idea where to get this json file. If I go to my firebase console (https://console.firebase.google.com/) I manage to donwload a json file but it does not contain any email adress and private key.

I managed to find a json file that contains an email adress and a private key in my google cloud platform console (http://console.cloud.google.com) by goind into the "API Manager > Credentials" menu. Surprisingly my firebase app was showed there. I copy and pasted the email and key into the sample code, then I got this error :

Warning: openssl_sign(): supplied key param cannot be coerced into a private key in /volume1/web/yeti/vendor/firebase/php-jwt/src/JWT.php on line 183 Fatal error: Uncaught exception 'DomainException' with message 'OpenSSL unable to sign data' in /volume1/web/yeti/vendor/firebase/php-jwt/src/JWT.php:185 Stack trace: #0 /volume1/web/yeti/vendor/firebase/php-jwt/src/JWT.php(154): Firebase\JWT\JWT::sign('eyJ0eXAiOiJKV1Q...', NULL, 'RS256') #1 /volume1/web/yeti/jwt.php(21): Firebase\JWT\JWT::encode(Array, NULL, 'RS256') #2 /volume1/web/yeti/jwt.php(24): create_custom_token('1234', false) #3 {main} thrown in /volume1/web/yeti/vendor/firebase/php-jwt/src/JWT.php on line 185

Does someone has an idea of what I'm doing wrong ?

Thanks

解决方案

Did you find the solution ? Still experiencing the same issue ! Works with HS256 and doesn't with RS256. Is it google cloud kind of limitation ?

Thank you so much ! @dbburgess

Problem: Was using the wrong key and email. These should be generated in the Google Cloud credentials section that corresponds to the Firebase project.

Solution:

• Go to 'console.cloud.google.com'.
• Select the related Firebase project.
• Then 'API Manager' -> 'Credentials'.
• 'Create Credentials' -> 'Service Account Key' -> Choose JSON.
• The created file will contain the needed 'private_key' & 'client_email'.

Fill the values:

$service_account_email = "[e-mail]"; $private_key = "-----BEGIN PRIVATE KEY-----\nSoneVeryVeryLongKey=\n-----END PRIVATE KEY-----\n"; $uid = 'UserToUseInFirebaseRules'; $is_premium_account = $uid;

You shouldn't need to change anything in the "create_custom_token" function, maybe the expiration date/time according to your needs.

Then call the function:

create_custom_token($uid, $is_premium_account);
