python - 如何使用 requests、Python 和 Firebase 添加数据而不是替换数据

Question

我正在使用 requests 模块在 Firebase 中获取和设置数据。假设我有一个现有的火力基地，http://mytest.firebaseio.com ，看起来像这样

|somewhere
  |--test1
    |--exists: 1

我想向其中添加数据，所以它看起来像:

|somewhere
  |--test1
    |--exists: 1
    |--arrived: 1

我的直觉是使用put()，例如:

r = requests.put('http://mytest.firebaseio.com/test1.json',data='{"arrived":1}')

但这会导致删除除了添加arrived: 1之外的exists: 1，例如:

|somewhere
  |--test1
    |--arrived: 1

如何添加 arrived: 1 而不删除 exists: 1？

来自docs :

You can update specific children at a location without overwriting existing data with a PATCH request. Named children in the data being written with PATCH will be written, but omitted children will not be deleted. This is equivalent to the update( ) function.

所以你想使用 requests.patch() 而不是 requests.put()。
