OIC - Create a resuable integration to write or move and delete files from AWS S3 using Rest

Usecase: Here, we will create a reusable integration for example say OIC_FILE_Handler which will do move and delete file from a specified directory of AWS S3 bucket using rest feature.

It will perform the following operations:

1. Write file
2. Delete file
3. Move file (mixed option 1 and option2)

REST trigger Request JSON:

{

"base64FileRef":"",

"sourceFileName":"",

"sourceDirectory":"",

"moveFileFlag":"",

"targetDirectory":"",

"targetFileName":"",

"deleteSourceFileFlag";"",

"deleteDirectory":""

}

REST Response JSON:

{

"jobStatus":"SUCCEEDED",

"fileMoved":"Y",

"fileDeleted":"N",

"exceptionCode":"",

"exceptionReason":"",

"exceptionDetails":""

}

Implemetation logic steps:

1. Create a AWS S3 rest connection
2. Create a App driven orchestration pattern and configure rest to accept the base64 encoded file, source path, delete path, source and delete directories and different flags. 
3. Assign globals:
1. varBasePathAndFile : Concat(deleteDirectory  sourceFileName)
2. varMovePathAndFile : concat(targetDirectory, targetFileName)
3. varFileref: ""
4. varMoveComplete : N
5. varDeletecomplete: N
6. varFileStatus : "error"
7. varCounter : 0.0
4. IF base64FileRef != empty, then decode base64 to file reference using decodebase64ToReference().
5. If moveFileFlag = Y, call S3 rest service to place the file to the specified  directory and map the decoded file ref to stream reference.
1. Resource path: /{pathAndFileName}
2. VERB: put
3. Request payload as Binary - application/zip
4. Also, put a retry logic to place the files to S3 3 times
1. Take a scope
2. While conditon: varFileStatus ="error" and varCounter <3.0
3. If success, assign varFileStaus ="success"
4. Under scope > default fault handler > increment counter +1
5. Update that varMoveComplete = Y if it is success
6. IF deleteSourceFileFlag = Y , Call S3 rest service nad configure below:
1. Resource path: /{pathAndFileName}
2. Verb: Delete
3. Map the varBasePathandFileName 
4. If it is success,  assign deleteComplete =Y
7. Update the response of the rest - fileMoved, fileDeleted and jobStatus.
8. Update the exception scope fault status from main scope fault handler
