Re: Is it possible to to create a dynamic Processor through API call from PHP

[ledor473]

Hi, 

I don't think the ListenHTTP can send an HTTP request to another URL, but it 
will most likely send an HTTP response to the sender (to say that it received 
the call)

Otherwise if the URL is in the payload of the call made to ListenHTTP, you 
could extract it in your Flow and then use InvokeHTTP to send another request 
to the callback URL.

Isn't the response returned by ListenHTTP enough? 
Will the callback be used to confirm that the flow is completed or something 
like that?

Hope this helps, 
Louis-Etienne

Re: Is it possible to to create a dynamic Processor through API call from PHP

Hello Kacem,

There are multiple different ways to get information into NiFi. ListenHTTP 
would be the easiest way to start an HTTP Server that is used to receive 
FlowFiles from remote sources. Assuming your PHP code only acts as a router, 
ListenHTTP should allow you to bypass the PHP code entirely and just launch the 
workflow when it receives an HTTP request from the Web Service.

If the PHP code is necessary and it's running on the same box as NiFi then you 
could use the GetFile processor. That mean you write a file via PHP then NiFi 
would grab the file and process it whenever possible. Of course there are 
considerations you have to take into account when you start putting things 
directly onto the file system.
 
There are many other options for getting files into NiFi and if either of these 
options don't fit your use-case just let us know.

Hello everyone,

So i'm subscribing to an API Callback in a Web service that send a post request 
once new data is available. I'm receiving this call through PHP.

Is it possible to trigger a processor to retrieve the whole data and launch the 
workflow of processing for that data through another API Call from my PHP Code?

(Web service send an API Callback --> My PHP code was listening --> Send an API 
call to Nifi to launch a processor with specific attributes)

Another question: It seems like Nifi has ListenHTTP processor. does it allow to 
have an url to be used as a callback (which means is accessible through the 
network to be used as a API Callback url?).

Thanks in advance.

Hello everyone,

So i'm subscribing to an API Callback in a Web service that send a post
request once new data is available. I'm receiving this call through PHP.

Is it possible to trigger a processor to retrieve the whole data and launch
the workflow of processing for that data through another API Call from my
PHP Code?

(Web service send an API Callback --> My PHP code was listening --> Send an
API call to Nifi to launch a processor with specific attributes)

Another question: It seems like Nifi has ListenHTTP processor. does it
allow to have an url to be used as a callback (which means is accessible
through the network to be used as a API Callback url?).

Thanks in advance.

Hello Chakri

I updated the downloads page to provide a convenient link to the
release archives.

Thanks Chris for the pointer to that!
