Set for each entry in array #112
Description
Activity
Hi,
I am looking for the same, which allows to replace some entry in array on the fly. My app just receives json data from server as following and want to modify it in place:
"content":
...
"list": [
{
"name": "abc",
...
},
{
"name": "xyz",
...
}
...
]I can get the name from array, with the follow code snippet. If I dump the return byte slice val, it looks Set has taken effect but I can't set it back to the original slice (body). Any suggestion? Thanks
jsonparser.ArrayEach(body, func(value []byte, dataType jsonparser.ValueType, offset int, err error) { log.Println(string(value)) v, rErr := jsonparser.GetString(value, "name") if rErr == nil { log.Println(offset, v) } else { log.Println(rErr) } val, wErr := jsonparser.Set(value, []byte("An example"),"name") if wErr == nil { value = val } else { log.Println(wErr) } }, "content", "list")@Nighthawk22 , @ajeecai
What about do it like:data := `[{"key":123}]` byteData := []byte(data) i := 0 jsonparser.ArrayEach(byteData, func(value []byte, dataType jsonparser.ValueType, offset int, err error) { byteData, _ = jsonparser.Set(byteData, []byte("124"), fmt.Sprintf("[%d]", i), "key") i++ })- added a commit that references this issue

Hello!
Would it be possible to add the possibility to set the value for each element in the array like this:
jsonparser.Set(jsonBody, []byte("\"\""), "issuesData", "issues", "[]", "extraFields", "[]", "html")Thanks in advance,
