Kattle sends post request and kattlepost request

Kattle sends post request and kattlepost request

I. Introduction
Kattle is an open-source ETL Tool written in java. It can be run on Windows, Linux, and Unix, and data extraction is efficient and stable. It allows you to manage data from different databases and describe what we need to do by providing a graphical user environment. The pdi-ce-5.4.0.1-130 is used here. For http://community.pentaho.com/projects/data-integration.

Ii. Example

1. Requirements: A system releases an interface, requests the interface address in post mode, and places the parameters in the Request body. After the interface is processed, the corresponding information is returned. Now we need to use kattle to complete this job.

2. The process is as follows:

Idea: Build parameters --> send post request --> get corresponding data --> subsequent processing (print logs)

The kattle design flowchart is as follows:

1) Table input is as follows:

2) construct parameters

3) HTTP Post requests

The fields tab mainly configures Request Parameters and other information, so no configuration is required if it is not used.

4) obtain result data

5) print logs

The running log result is as follows:
