使用 REST 将数据保存到 Firebase

Question

I'm using Firebase to store application tokens with names, using the REST api.

This is the data structure I'm using:

This is the data structure after I add a new application.

This is the command I use.

curl -X POST -d "{\"3ba7792jae16328\":{\"name\":\"Test 2\"}}" \ https://xxx.firebaseio.com/apps.json

I don't want the unique ID that the POST request adds to my data structure. I already tried with a PUT request but it override all the data inside the "apps" node. Anyways this is the PUT command I tried.

curl -X POST -d "{\"3ba7792jae16328\":{\"name\":\"Test 2\"}}" \ https://xxx.firebaseio.com/apps.json

Is there another way to add data and preserve my structure?

(Use the auto generated POST tokens as my own application tokens is not a valid answer)

Answer 1

You should put your self-generated ID into the URL:

curl -X POST -d "{\":{\"name\":\"Test 2\"}" \ https://xxx.firebaseio.com/apps/3ba7792jae16328.json

Firebase always overwrites (unless you use PATCH ) the entire node at the URL you indicate. So it's important that you specify the URL up to the level that you want to overwrite data.

There are two ways:

• if you want to add on row:

  method: PUT

  url: https://yourID.firebaseio.com/pages/your_object_name.json

  data:

   { "1": { "id": "5", "name": "page 4" } }

• if you want to add multiple rows:

  methode: PATCH

  url: https://yourID.firebaseio.com/pages.json

  data:

   { "1": { "id": "5", "name": "page 4" }, "2": { "id": "5", "name": "page 4" }, "3": { "id": "5", "name": "page 4" } }
