Massimiliano Nigrelli created NIFI-3435:
-------------------------------------------
Summary: Allow Expression Language for "Trusted Hostname"
attribute in the InvokeHTTP processor
Key: NIFI-3435
URL: https://issues.apache.org/jira/browse/NIFI-3435
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.0.0
Environment: CentOS7 on Virtualised VMs (OpenStack)
Reporter: Massimiliano Nigrelli
Priority: Minor
Attachments: JiraIssueInvokeHttpTrustedHostname.png
To whom it may concern,
I have the following issue: I use Nifi to retrieve some values from different
REST endpoints (HTTPS).
Well, in order to have something easily configurable, I have placed the URL of
each REST Service I need to access in a configuration file (one file per
endpoint). When it comes to configure the InvokeHTTPProcessor there is no way
to have the TrustedHostname varying depending on the configuration file as I
cannot use expression language.
In such a way I should need to duplicate the InvokeHTTP processor for a number
of times that is equal to all the endpoints from which I would need to retrieve
data from (as in the following example):
endpoint 1 ----------------- IP of URL1 ---------------- 1st InvokeHttp -
TrsustedHostname for IP of URL1
....................................................................................................
....................................................................................................
endpoint N ----------------- IP of URLN ---------------- Nth InvokeHttp -
TrsustedHostname for IP of URLN
I would rather have only one single InvokeHTTP processor istantiated:
endpoint 1 ----------------- IP of URL1 ---------------- InvokeHttp -
TrustedHostname = ${property}
....................................................................................................
....................................................................................................
endpoint N ----------------- IP of URLN ---------------- InvokeHttp -
TrustedHostname = ${property}
Hope I have been clear,
Regards,
Massimiliano
