如果你使用的是。net，那么Json。NET支持JSON之上的LINQ查询。这篇文章有一些例子。它支持过滤、映射、分组等。

我使用SQLite: https://sqlite.org/json1.html

这很好，因为你可以使用实际的SQL语言，SQLite非常快。

首先我创建一个临时表:

create temp table data as select value from json_each(readfile('data.json'))

然后使用SQLite JSON函数:

select value->'$.foo' foo, count(value->'$.bar') nbar from data group by foo 

另一种方法是使用mongoDB，你可以将JSON存储在mongoDB中，然后通过mongoDB查询语法进行查询。

下面是一些简单的javascript库，也可以做到这一点:

Dollar Q is a nice lightweight library. It has a familiar feel to the chaining syntax made popular by jQuery and is only 373 SLOC. SpahQL is a fully featured query language with a syntax similar to XPath (Homepage, Github jFunk is an in progress query language, with a syntax similar to CSS/jQuery selectors. It looked promising, but hasn't had any development beyond its in initial commit. (added 2014): the jq command line tool has a neat syntax, but unfortunately it is a c library. Example usage: < package.json jq '.dependencies | to_entries | .[] | select(.value | startswith("git")) | .key'

如果你想使用纯javascript试试这个:

Var对象= {result: {data: {point1: "x"， value: 2}， foo: {bar: 7}}}， Path = 'result.data.value'， getValue = (o, p) => p.split('.')。Reduce ((r, k) => r[k]， o); console.log (getValue(对象,路径));

我推荐我正在做的项目jLinq。我在寻求反馈，所以我很有兴趣听听你的想法。

如果让你写查询类似于你会在LINQ…

var results = jLinq.from(records.users)

    //you can join records
    .join(records.locations, "location", "locationId", "id")

    //write queries on the data
    .startsWith("firstname", "j")
    .or("k") //automatically remembers field and command names

    //even query joined items
    .equals("location.state", "TX")

    //and even do custom selections
    .select(function(rec) {
        return {
            fullname : rec.firstname + " " + rec.lastname,
            city : rec.location.city,
            ageInTenYears : (rec.age + 10)
        };
    });

它也是完全可扩展的!
