How to convert key-value format string to map in golang?

Question

There is a format string like this:

"key1=value1&key2=value2"

How to convert this string to a map elegantly:

{"key1":"value1","key2":"value2"}

Is there any good utils like Guava's MapSplitter?

do you want to parse the keys as string and the values as typed value? Like, k1=5&k2=five => {"k1": 5, "k2": "five"} or {"k1": "5", "k2": "five"}? — Shudipta Sharma

You can use strings.Split() function twice to split the entire string into a key=value pairs by & and then again to split each pair to key and value by =.
