Hi ,
Here we are going to learn how to encode a string to Base64 format in Apex
Eg:
String urlparam = 'Salesforce Techbook';
String urlString = EncodingUtil.base64Encode(Blob.valueof(urlparam));
System.debug(urlString);
Output: U2FsZXNmb3JjZSBUZWNoYm9vaw==

Hi ,
Here we are going to learn how to generate JSON with the help of Map in apex.
Let's take the following JSON and see how to generate the same with the help of Map in apex.
JSON:
{
"lastname":"SF",
"firstname":"Techbook",
"account":{
"name":"Salesforce Techbook",
"address":{
"shippingstreet":"test_street",
"shippingcity":"test_city"
}
},
"phone":"12454565",
"mailingcity":"test_cont_City"
}
Let's try to generate the above JSON with Map:
//Preparation of outer JSON object
Map<String,Object> jsonGenMap = new Map<String,Object>();
jsonGenMap.put('lastname','SF');
jsonGenMap.put('firstname','Techbook');
jsonGenMap.put('phone','12454565');
jsonGenMap.put('mailingcity','test_cont_City');
//Preparation of "account" JSON object
Map<String,Object> jsonActMap = new Map<String,Object>();
jsonActMap.put('name','Salesforce Techbook');
Map<String,Object> jsonActAddressMap = new Map<String,Object>();
jsonActAddressMap.put('shippingstreet','test_street');
jsonActAddressMap.put('shippingcity','test_city');
jsonActMap.put('address',jsonActAddressMap);
jsonGenMap.put('account',jsonActMap);
//Generation of JSON from the above with the help of "serialize" method under "JSON" class.
string jsonstring = JSON.serialize(jsonGenMap);
System.debug(jsonstring);

Hi,
Here we are going to learn how to get the values from an array that has plain values instead of a list of JSON objects.
Let's take the example below.
Here we have "langaugeskills" array in the following JSON String with the values "English,Hindi, Telugu". To capture those values we have to follow the below approach.
String jsonStr = '{"LastName": "Balu","langaugeskills": ["English","Hindi","Telugu"]}';
Map<String,Object> jsonMap = (Map<String,Object>)JSON.deserializeUntyped(jsonStr);
System.debug('JSON :::'+jsonMap);
List<Object> langSkillsList = (List<Object>)jsonMap.get('langaugeskills');
System.debug('---->'+langSkillsList);
for(Object langStr:langSkillsList){
System.debug((String)langStr);
}
output:
