如何在json查询中解析键“ array.fruits”。

Answer 1

您可以使用bracket notation property accessor来获得所需的值：

const data = {
    "key" : "value",
    "array.fruits" : [
        { "key" : 1 },
        { "key" : 2, "dictionary": {
                "a": "Apple",
                "b": "Butterfly",
                "c": "Cat",
                "d": "Dog"
            } },
        { "key" : 3 }
    ]
}

console.dir(data["array.fruits"])
