如何通过HTTP REST API访问我的Firebase数据库？ [英] How do I access my Firebase Database via HTTP REST API?

问题描述

感谢此答案我可以通过HTTP REST API和电子邮件/密码连接到Firebase 3。使用此API登录会返回用于访问Firebase数据库的访问令牌。此访问令牌在1小时后过期。登录后还会返回一个刷新令牌，我可以使用该令牌刷新我的访问令牌。这是我特别做的：

方法：

$ $ p $ POST


网址：

  https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=<my-firebase-api-key> 
  

有效负载：

 < code $ {
 email：< email>，
 password：< password>，
 returnSecureToken：true 
 
  

回应：



  { 
kind：identitytoolkit＃VerifyPasswordResponse，
localId：< firebase-user-id>，//用来唯一标识用户
email： < email>，
displayName：，
idToken：< provider-id-token>，//将其用作数据库请求中的认证令牌
registered：true，
refreshToken：< refresh-token>，
expiresIn：3600
} 
  

在刷新我的访问令牌的情况下：



URL：

b
$ b

  https://securetoken.googleapis.com/v1/token?key=<my-firebase-api-key> 
  

有效负载：

  {
 grant_type：refresh_token，
 refresh_token：< refresh-token> 
 
 $ / code $ / pre 
 
 $ p 
 
 $ $ 
access_token：< access-token>，
expires_in：3600，
token_type：持票人，
refresh_token：< refresh-token>，
id_token：< id-token>，
user_id：< user-id> ;，
project_id：< project-id> 
 
 
 
 
 
如何通过HTTP REST API访问我的数据库有我的访问令牌？ 
所以在与技术支持沟通后，我的答案是：$ / $> $ / $> 
 
 
在你的数据库规则中，包含一些类似于你正在做的事情的东西： 
 
 
 <$ c 
rules：{
users：{
$ user_id：{
 //授予对此用户帐户所有者的写入权限
 //其uid必须与该键完全匹配（$ user_id）
.write：$ user_id === auth.uid，
.read：$ user_id === auth.uid

} 
} 
} 
  
 
 
在你的数据库中，创建一个 users 表，并在其中创建一个名为< user-id> 您正在使用的验证电子邮件/密码帐户。在该表中，您可以通过 access-key 访问该信息。然后发送这样的请求： 
 
 
  https：//  samplechat.firebaseio-demo.com/users/<user-id>.json?auth=<access-key> 
  
其中 access-key 是关键可以被称为 idToken ， id_Token 或 access_key  in来自Google的JSON响应。  
Thanks to this answer I am able to connect to Firebase 3 via HTTP REST API and an email/password. Logging in with this API returns an access token that is used to access the Firebase Database. This access token expires after 1 hour. A refresh token is also returned after logging in, which I can use to refresh my access token. Here is what I am doing specifically:

Method:
POST
URL:
https://www.googleapis.com/identitytoolkit/v3/relyingparty/verifyPassword?key=<my-firebase-api-key>
Payload:
{
    email: "<email>",
    password: "<password>",
    returnSecureToken: true
}
Response:
{
    "kind": "identitytoolkit#VerifyPasswordResponse",
    "localId": "<firebase-user-id>", // Use this to uniquely identify users
    "email": "<email>",
    "displayName": "",
    "idToken": "<provider-id-token>", // Use this as the auth token in database requests
    "registered": true,
    "refreshToken": "<refresh-token>",
    "expiresIn": "3600"
}
In the case of refreshing my access token:

URL: 
https://securetoken.googleapis.com/v1/token?key=<my-firebase-api-key>
Payload:
{
    grant_type: "refresh_token",
    refresh_token: "<refresh-token>"
}
Response:
{
  "access_token": "<access-token>",
  "expires_in": "3600",
  "token_type": "Bearer",
  "refresh_token": "<refresh-token>",
  "id_token": "<id-token>",
  "user_id": "<user-id>",
  "project_id": "<project-id>"
}
How do I access my database via HTTP REST API given that I have my access token?
解决方案
So after communicating with technical support, here's my answer:

In your database rules, include something like this that is compatible with what you're doing:
{
"rules": {
"users": {
"$user_id": {
// grants write access to the owner of this user account
// whose uid must exactly match the key ($user_id)
".write": "$user_id === auth.uid",
".read": "$user_id === auth.uid"
}
    }
  } 
}
And in your database, create a users table, and within that, create a table with the name of your <user-id> of the authentication email/password account you are using. Within that table is the information you will be able to access via your access-key. 

Then send a request like this:
https://samplechat.firebaseio-demo.com/users/<user-id>.json?auth=<access-key>
Where access-key is the key that can be known as idToken, id_Token, or access_key in JSON responses from Google.
