Stream Wrapper

The stream_wrapper settings allow you to register filesystems with a specified domain and then use as a stream wrapper anywhere in your code like: gaufrette://domain/file.txt

Parameters

protocol The protocol name like gaufrette://… (default gaufrette)
filesystem An array that contains filesystems that you want to register to this stream_wrapper. If you set array keys these will be used as an alias for the filesystem (see examples below) (default all filesystems without aliases)

Example 1

Using default settings, the protocol is "gaufrette" and all filesystems will be served

# app/config/config.yml
knp_gaufrette:
    adapters:
        backup: #...
        amazon: #...

    filesystems:
        backup1:
            adapter: backup
        amazonS3:
            adapter: amazon

    stream_wrapper: ~

gaufrette://backup1/...
gaufrette://amazonS3/...

Example 2

We define the protocol as "data", all filesystem will still be served (by default)

# app/config/config.yml
knp_gaufrette:
    filesystems:
        #...

    stream_wrapper:
        protocol: data

data://backup1/...
data://amazonS3/...

Example 3

We define the protocol as data and define which filesystem(s) will be available

# app/config/config.yml
knp_gaufrette:
    filesystems:
        #...

    stream_wrapper:
        protocol: data
        filesystems:
            - backup1

data://backup1/... (works since it is defined above)
data://amazonS3/... (will not be available)

Example 4

We define the protocol as data and define which filesystems will be available using array keys to set domain aliases

# app/config/config.yml
knp_gaufrette:
    filesystems:
        #...

    stream_wrapper:
        protocol: data
        filesystems:
            backup: backup1
            pictures: amazonS3

data://backup/...
data://pictures/...
