Multipart Encoded HTTP Entity Creator
Palladian Nodes for KNIME Workbench version 1.8.0.201907271536 by palladian.ws; Philipp Katz, Klemens Muthmann, David Urbansky.
Combines string and/or binary data to an HTTP multipart/form-data encoded request. The output is a binary cell which contains the combined multipart data and which then can be sent by the “HTTP Retriever” node.
Important: This node creates a dynamic boundary string, e.g. --xoxoxoxoxoxoxoxoxoxo_1512650655272.
This string is appended as separate column to the output table which contains the entity’s content type.
This very string needs to be selected in the HTTP Retriever’s “HTTP entity content type” setting.
We recommend to connect a “Table Row to Variable” node to this node’s out port, which gets connected to
the HTTP Retriever, where you select content type through the flow variable configuration.
Options
- Input column
- Name of the columns with string or binary data.
- Content type
- The content type of the current part, e.g.
text/plainorimage/gif - Name
- The name of the current part
- File name (*)
- File name for the current part
- Name of appended entity column
- The name of the added column which contains the multipart data
Input Ports
Output Ports
- Table with appended HTTP entity and content type column which are created from the selected part columns in the input table.
