Tips
通过json patch的时候
- 如果key包含
/
, 需要将/
转义成~1
- 如果values是个json字符串,需要将json字符串里的
"
转义成\"
- 如果返回错误
the server rejected our request due to an error in our request
,需要检查一下,父节点是否存在。比如 add "/metadata/annotations/foo",时,需要确认"/metadata/annotations"是否存在,如果不存在,需要添加
[
{"op":"add","path":"/metadata/annotations","value":{}},
{"op":"add","path":"/metadata/annotations/foo","value": "bar"}
]
