MultipartEncodedHttpEntityCreator

Palladian Nodes for KNIME Workbench version 1.7.0.v201807041014 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 HttpRetriever 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 HttpRetriever’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 HttpRetriever, where you select content type through the flow variable configuration.
