json - JSON Patch RFC 中的波浪号转义应该如何操作？

Question

引用https://www.rfc-editor.org/rfc/rfc6902#appendix-A.14 :

A.14. ~ Escape Ordering

An example target JSON document:

{
  "/": 9,
  "~1": 10
}

A JSON Patch document:

[
  {"op": "test", "path": "/~01", "value": 10}
]

The resulting JSON document:

{
  "/": 9,
  "~1": 10
}

我正在编写此 RFC 的实现，但我陷入了困境。这是要实现什么目标，它应该如何工作？

假设第一部分的答案是“允许引用包含/s 的 json 键名称”，您会怎么做？

Answer 1

~字符是JSON指针中的关键字。因此，我们需要将其“编码”为~0。引用jsonpatch.com ,

If you need to refer to a key with ~ or / in its name, you must escape the characters with ~0 and ~1 respectively. For example, to get "baz" from { "foo/bar~": "baz" } you’d use the pointer /foo~1bar~0

本质上，

[
  {"op": "test", "path": "/~01", "value": 10}
]

解码后的结果

[
  {"op": "test", "path": "/~1", "value": 10}
]
