echo://${returnvalue}
- where return value is a base64
string. const returnvalue = Buffer.from("My return value").toString('base64')
echo+json://name/${returnvalue}
, const returnvalue = Buffer.from('{"name":"Tal Muskal"}').toString('base64')
echo+post+json://timestamp/${body}/${content}
- where body is const body = Buffer.from('{"block_num_or_id":"36568000"}').toString('base64')
. In this example you specify the type of request: echo+post+json
then the key mapping timestamp
then the body of the POST request, encoded in base64, then the URL path const content = Buffer.from('{"timestamp":"2019-01-09T18:20:23.000"}').toString('base64');
