HTTP Result Data Extractor

Palladian for KNIME version 2.4.1.202103282119 by palladian.ws

This node allows to extract the details of an HTTP result into columns which can be processed by other KNIME nodes. The complete HTTP body is either returned as String or Binary value. The status code is returned as a number and optionally all HTTP header fields are returned as individual columns.

Options

HTTP Result input
The column in the input table which holds the HTTP Result.
Append HTTP status code
Appends the HTTP status code.
Append header information
Appends all available HTTP headers as one column per header. If a result does not contain a specific header, a missing cell is inserted.
Append redirected locations
Appends a list cell which contains all URL locations which were requested (in case there were no redirects, the list contains exactly one elements; in case of 301/302 redirects, the list will contain one entry for each requested URL, and the last entry in the list represents the final URL)
Create binary cell
Activate to append a Binary cell with the result’s content (rather than a String cell).
