问题是如何获得"来自"元件?剩下的不是问题
我知道在https://github.com/json-iterator/可以做到,但我无法弄清楚它是如何运作的
JSON:
{
"ab": 123456789,
"cd": [
[
4,
1234,
123456,
1000000001,
1234567890,
"text",
{
"from": "123456"
}
],
[
4,
4321,
654321,
1000000001,
9876543210,
"text",
{
"from": "654321"
}
]
]
}
Golang:
type test struct {
Ab int `json:"ab"`
Cd [][]interface{} `json:"cd"`
}
var testvar test
json.Unmarshal(Data, &testvar)
testvar.Cd[0][6]["from"].(string)
错误:
invalid operation: testvar.Cd[0][6]["from"] (type interface {} does not support indexing)
答案 0 :(得分:0)
很简单:它是map[string]interface{}
因此
m, ok := testvar.Cd[0][6].(map[string]interface{})
fmt.Println(m, ok, m["from"])
