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,
and as a flow varaible.
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.
