    Name string `json:"name"`
}

func TestAnything3(t *testing.T) {
    var s = `[

        ]
    ]`
    var ps []*Person
    err := jsoniter.Unmarshal([]byte(s), &ps)
    fmt.Printf("ps: len:%v\n", len(ps))
    fmt.Printf("ps: value:\n")
    for k, v := range ps {
        fmt.Printf("k:%v, v:%v\n", k, v)
    }
    fmt.Printf("err: %v\n", err)
}

result: === RUN TestAnything3 ps: len:1 ps: value: k:0, v:&{0 } err: nil --- PASS: TestAnything3 (0.00s) PASS
