在Golang中解组数组json

Question

How would I unmarshal something like this:

[
2,
"19223201",
"SomeString",
{
    "SomeField": "FieldValue",
    "SomeField2": "FieldValue2", "SomeFieldN": "FieldValueN",       }
]

Answer 1

You can use interface{} if you have not define any interface and unmarshal into interface type slice.

import (
    "fmt"
    "encoding/json"
)

func main() {

    strBytes := []byte(`[2,"19223201", "SomeString",{"SomeField": "FieldValue","SomeField2": "FieldValue2", "SomeFieldN": "FieldValueN"}]`)
    keys := make([]interface{},0)

    json.Unmarshal(strBytes, &keys)
    fmt.Println(keys)

}
