Hi liangl7510 
 I have developed a solution that achieve this dynamically. Below is the code for your reference. 
 a!localVariables( local!input: "[key1:value1,key2:value2,key3:value3,key4:value4]", local!stripText: mid(local!input, 2, len(local!input) - 2), local!tempString: split(split(local!stripText, ","), ":"), local!dict: a!map(), local!updatedMaps: a!forEach( items: local!tempString, expression: if( mod(fv!index, 2) = 0, {}, a!update( local!dict, fv!item, index(local!tempString, fv!index + 1, null()) ) ) ), local!keys: a!flatten( a!forEach( items: local!updatedMaps, expression: a!keys(fv!item) ) ), a!update( a!map(), local!keys, a!forEach( items: local!updatedMaps, expression: index(fv!item, a!keys(fv!item), null) ) ) )

liangl7510 , you can use the below code to convert you input string to a valid list of Map type variable and thn by using simple index function you can get the values based on the keys. 
 a!localVariables(
 local!input: substitute(
 substitute(
 "[key1:value1,key2:value2,key3:value3,key4:value4]",
 "[",
 ""
 ),
 "]",
 ""
 ),
 local!arrayOfText: split(local!input, ","),
 local!finalMap: a!flatten(
 a!forEach(
 items: local!arrayOfText,
 expression: a!localVariables(
 local!temp: split(fv!item, ":"),
 {
 a!map(key: local!temp[1], Value: local!temp[2])
 }
 )
 )
 ),
 index(
 local!finalMap.Value,
 wherecontains("key1", local!finalMap.key),
 ""
 )
)
