你能在 JSON 中嵌入 "commands" 吗？

Question

我有一些 JSON（我们称它为 json1），我想将它与其他一些 JSON（json2）结合起来。我不只是想合并或附加数据，我还希望能够通过在 json2 中嵌入“命令”来从 json1 中删除数据。

例子

json1 = { 
  "a": 1,
  "b": "xyz",
  "c": ["foo", "bar"]
}

json2 = {
  "b": "hello world",
  "d": 4,
  "c": ["-foo", "+foobar"],
}

output = combine(json1, json2) 

// Expected result from the fictional "combine()" method
output = {
  "a": 1,
  "b": "hello world",
  "c": ["bar", "foobar"],
  "d": 4
}

当然我可以想出我自己的语法和逻辑，但我很好奇是否有任何现有技术可以使用 JSON?

来操纵 JSON

免责声明：我不是在问 recommendations for books, tools, software libraries (or more). I merely have a practical, answerable problem that is unique to software development pertaining to a specific programming problem and am asking about software tools commonly used by programmers, or possibly a software algorithm。哎呀

使用 jsonpatch，您的示例将转换为 JSON Patch 类似于：

[
  { "op": "replace", "path": "/b", "value": "hello world" },
  { "op": "add", "path": "/d", "value": 4 },
  { "op": "replace", "path": "/c/0", "value": "foobar"}
]
