I need to have a JSON Formatted Base64 for this, but I am not sure how to change this string to have it as Base64 JSON Format.

public  String requestBody =  '{["Um05dkxFSmhjZz09"]}';

Um05dkxFSmhjZz09 this is already in Base64

  • Why do you need your JSON to be base64?

  • @AdrianLarson its for my test class Fake respond, and I receive String M = (String)JSON.deserializeStrict(responseBody,String.class); b = EncodingUtil.base64Decode(M); in my class, so my test string needs to be in that format

  • I am really confused with data structure inside string, it looks like a Hash Map without key but an array Mar 1, 2016 at 17:41
  • @karthikselva its a fake response

  • do you want to create Base64 encoded value of 'Um05dkxFSmhjZz09'?? or the whole String '{["Um05dkxFSmhjZz09"]}'?

Encoding/Decoding is different from Serialization/Deserialization

  • The JSON you have for fake response is malformed.
  • If all you are getting from the response is Base64 encoded string, you don't need to deserialize
  • So in this case there is no need for JSON at all

Try this instead:

public String requestBody =  'Um05dkxFSmhjZz09';
b = EncodingUtil.base64Decode(requestBody);

    Thank you for the respond I just use this to make it JSON String formatJSON = JSON.serializePretty(requestBody);

A JSON works in a key-value pair.

When you are creating JSON here, I see the value, but not the key. Hence the solution would be to create a key-value pair instead.

Like:

public  String requestBody =  '{"yourkey": "Um05dkxFSmhjZz09"}'  //This is a JSON String

If you intend to use an array of values, use:

public  String requestBody =  '{"yourkeys": ["Um05dkxFSmhjZz09"]}'

and to validate any JSON in future, you could always use JSONLint

in test cases we can actually use Base64 and do

String formatJSON = JSON.serializePretty(requestBody); 

to turn it into Json
