go json的key为数字怎么解析,如何解析Golang中的JSON字符串？

Given a URL like the following.

http://127.0.0.1:3001/find?field=hostname&field=App&filters=["hostname":"example.com,"type":"vm"]

How do I extract JSON values corresponding to keys for eg: hostname 'example.com' and type 'vm'.

I am trying

filters := r.URL.Query()["filters"]

which gives following output:

[["hostname":"example.com,"type":"vm"]]

解决方案

Use the encoding/json package to parse JSON. The query string in the example URL does not contain valid JSON.

Here's an example show how to use the JSON parser on a slightly different URL.

s := `http://127.0.0.1:3001/find?field=hostname&field=App&filters={"hostname":"example.com","type":"vm"}`

u, err := url.Parse(s)

if err != nil {

log.Fatal(err)

}

var v map[string]string

err = json.Unmarshal([]byte(u.Query().Get("filters")), &v)

if err != nil {

log.Fatal(err)

}

fmt.Println(v)
