This way, the user will see the JSON string with related information.
Squish: Here Comes The Best Url Shortener Free To CommentAnd as always, please feel free to comment andor ask questions.Generally, OAuth provides to clients a secure delegated access to server resources on behalf of a resource owner.It specifies a process for resource owners to authorize third-party access to their server resources without sharing their credentials.
The third party then uses the access token to access the protected resources hosted by the resource server. ![]() It gives me the opportunity to use for the first time the ExecuteScript processor which allows user to execute custom scripts on the fly inside NiFi (you will find a lot of examples on this great site ). The thing is you need to identify yourself when sending the request. But in the case of the Twitter API, you have a nice documentation here. It lets you play around and gives great insights on each request to debug your own implementation of OAuth protocol. Then I use an UpdateAttribute processor to add attributes to my FF. In this case, I only add the parameters related to the specific request I want to execute. At the end, I use a PutFile processor to write the result of my request in a local directory. The first one is an UpdateAttribute to add all the parameters I need as attributes of my FF. Squish: Here Comes The Best Url Shortener Code In TheI set the script engine to Groovy and I put my script code in the script body property. A TreeMap ensures me that it is sorted on keys in alphabetical order. Lets be clear right now, I dont think Apache NiFi is the best option to propose such a service (this is not the idea behind this Apache project) but I believe this is an opportunity to play around with some processorsfunctionalities I never discussed so far. Since this is something we can do with Apache NiFi, it is interesting to see how this can be achieved. I also want to store statistics about the number of times my shortened URL has been used. And, in our use case, I want my shortened URL to be valid at least 24h. Once a request is received, a FlowFile is generated with attributes and content (if any). Handling different services with the same processor can be performed with the addition of a RouteOnAttribute processor (well see that in this implementation). Interaction with this service is typically accomplished via a DistributedMapCacheClient service. This feature is mainly used to share information across a NiFi cluster but can also be used at local level to store data in memory to be used along the flow. Consequently, I use a FetchDistributedMapCache processor to retrieve the JSON data associated to the given key.
