File

class resources.file.File

Base class: Resource

A file which is stored in Cloudomation.

To store data in a file there are three additional arguments for the save() method available:

import flow_api

def handler(system: flow_api.System, this: flow_api.Execution):
    # store a text (utf8 string)
    system.file('my-file.txt').save_text_content('text content')
    # read as base64
    assert system.file('my-file.txt').get_base64_content() == 'dGV4dCBjb250ZW50'
    # store bytes data
    system.file('my-file.dat').save_bytes_content(b'bytes data äöü')
    # read as text (utf8 string)
    assert system.file('my-file.dat').get_text_content() == 'bytes data äöü'
    # store a base64 encoded string
    system.file('my-file.ext').save_base64_content('Q2xvdWRvbWF0aW9u')
    # read as bytes
    assert system.file('my-file.ext').get_bytes_content() == b'Cloudomation'

    # list files
    for file_ in system.files():
        this.log(file_.get('name', 'size_bytes'))

    # clean up
    system.file('my-file.txt').delete()
    system.file('my-file.dat').delete()
    system.file('my-file.ext').delete()

    return this.success('all done')
