Let’s continue the migration of the BizTalk Mapper Extensions UtilityPack project and provide an overview of another set of libraries available for BizTalk Server 2020: Encoder Functoids.
📝 One-Minute Brief
Introduces the Encoder Functoids in the BizTalk Mapper Extensions UtilityPack for BizTalk Server 2020, enabling developers to encode and decode data (such as BASE64) directly within BizTalk maps to ensure safe and compatible data exchange.
Encoder Functoids
This library includes a suite of functoids that encode data directly inside the BizTalk mapper.
In practice, encoding transforms data so that different systems can safely and correctly consume it. However, the goal is not to keep information secret. Instead, encoding ensures data compatibility across systems.
Specifically, encoding converts data into another format using a publicly available scheme that systems can easily reverse. For example, you can encode and decode data using ASCII, BASE64, or UNICODE.
Finally, decoding performs the opposite operation. It converts the encoded data back into its original sequence of characters.
This project includes the following Custom Functoids:
- BASE64 Encoder Functoid: This functoid allows you to convert a string type into a BASE64 encoded string.
- The functoid takes one mandatory input parameter:
- A string that represents the text that you want to encode to BASE64
- The output of the functoid is a string. Example: U2FuZHJvIFBlcmVpcmE=
- The functoid takes one mandatory input parameter:
- BASE64 Decoder Functoid: This functoid allows you to decode BASE64-encoded text strings into the original sequence of characters.
- The functoid takes one mandatory input parameter:
- BASE64 string representation that you want to decode to a text string
- The output of the functoid is a string. Example: Sandro Pereira
- The functoid takes one mandatory input parameter:
BizTalk Mapper Extensions Utility Pack
BizTalk Mapper Extensions Utility Pack is a set of libraries that includes several useful functoids to include in a map, extending BizTalk Mapper’s capabilities.
