Getting URLs

​

Prerequisites

1. Access Permissions: Ensure that the user account has the necessary access rights.
2. Kafka Configuration:

• Verify Kafka Setup: Ensure proper configuration and accessibility of the Kafka messaging system.
• Kafka Topics: Understand the Kafka topics used for these operations.

3. Document Types: Prepare information for updating or deleting files:

• types: A list of document types.

​

Configuring the getting URLs process

1. Create a process with the following nodes:
   • Send Message Task (Kafka) - to send the get URLs request
   • Receive Message Task (Kafka) - to receive the get URLs reply
   • User Task node - where to perform the file upload action
   • Start / End Milestone nodes - to create a page
2. Configure the User Task node:

​

Node Config

• Data stream topics: Add the topic where the response will be sent; in this example ai.flowx.updates.document.html.persist.v1 and its key: uploadedDocument.

​

Actions

• Upload File action with two child actions:
  • Business Rule
  • Send Data to User Interface
• Save Data action

3. Configure the parameters for the Upload Action:

4. Next, configure the Message Event Send node by adding a Kafka Send Action and specifying the ..in Kafka topic to send the request.

Identify defined topics in your environment:

• Navigate to Platform Status > FlowX Components > document-plugin-mngt and press the eye icon on the right side.
• In the details screen, expand the KafkaTopicsHealthCheckIndicator line and then details → configuration → topic → document → get. Here will find the in and out topics for getting URLs for documents.

5. Fill in the body of the request message for the action:

• types: A list of document types.

​

Message request example

{
  "types": [
    "119435",
    "119435"
  ]
}

6. Configure the Receive Message Task (Kafka) by adding the ..out kafka topic on which the response will be sent.

​

Receiving the reply

• success: A boolean indicating whether the document exists and the URL was generated successfully.
• fullName: The full name of the document file, including the directory path.
• fileName: The name of the document file without the extension.
• fileExtension: The extension of the document file.
• url: The full download URL for the document.
