i'm pretty new to nifi, so i'm not sure this worded correctly or possible. i have a flow which ends with an invokehttp process that does a PUT to web server.
my naive understanding of this process is that when the flowfile hits invokehttp, the flow-attributes can be sent as key:value pairs via the http headers and the file-content gets PUT to the remote webserver via the http content-body is there a way to send the flow-attr and the flow-content (ie the entire flowfile) via the PUT? i have nifi on two ends of a connection, but in order to send the data from one to another i have to send it through a proxy like device. the near end of the device receives data from the PUT and far end does a POST to a remote nifi. this process works fine, but on the far end i only receive the file and none of the attributes (as expected). i cannot configure the proxy device to pass key:value pairs in the http headers. i'm presuming all the flow information would have to be sent via the PUT and then decoded by the nifi server on the far end. i'm hoping there's a simple connector to do this rather then having me munge all the data together into something like an xml or json file and send that.
