ArrayList 字符串 - 使用 Groovy 检索值

Question

Parsing the value from JSON and stored it into a variable using Groovy. below is the value stored in that variable.

[[UserName:usernameX, Password:passwordX]]

The format is Arraylist, how can I retrieve the UserName and Password value like [ usernameX and passwordX ].

Answer 1

Hmmm, double [[]] and no quotes. I don't know how your data gets into an ArrayList, but if you can get the data in a Groovy Map, you can do it like this:

Map a = ['UserName':'usernameX', 'Password':'passwordX']

a.each { k, v ->
    println v
}

prints:

usernameX
passwordX

Answer 2

You can convert the nested array-list straight into a map:

Map map = [[UserName:'usernameX', Password:'passwordX']].collectEntries{ [ it.UserName, it.Password ] }

assert map == [usernameX:'passwordX']
