Amazon S3 Connector 5.8 Examples

The following example shows how to store an image from a URL in Amazon S3, and retrieve and display the image.

Before You Begin

For this example to work in Anypoint Studio, you must provide Amazon Web Services credentials. You can either:

Replace the variables with their values in the code.
Provide the values for each variable in the src/main/resources/mule-artifact.properties file.

Example Steps

Create a new Mule project in Studio.
Drag an HTTP > Listener into the canvas, and select it to open the properties editor.
Add a new HTTP Listener Config global element:
1. In General Settings, click the + button:
2. Configure the following HTTP parameters, retain the default values for the other fields, and click OK.
  
  Field Value
  
  Name
  
  HTTP_Listener_Configuration
  
  Host
  
  127.0.0.1
  
  Port
  
  8081
3. Reference the HTTP Listener Configuration global element. In the General tab, specify the / Path.
Drag an Amazon S3 connector into the flow, and double-click the connector to open its properties editor.
If you don’t have an existing Amazon S3 connector global element to choose, click the + sign next to Extension Configuration field.
Configure the global element properties, and then click OK.

Field	Value
Name	HTTP_Listener_Configuration
Host	127.0.0.1
Port	8081

Configure the connector parameters:

Field Value

Field	Value
Display Name	Name for the connector instance, such as `Create bucket`.
Extension Configuration	Global configuration for the connector.
Bucket Name	`${config.bucket}`
Region	Region, for example US_STANDARD (default).
Canned ACL	PRIVATE (default) access control list. A canned ACL is a predefined grant.

Display Name

Name for the connector instance, such as Create bucket.

Extension Configuration

Global configuration for the connector.

Bucket Name

${config.bucket}

Region

Region, for example US_STANDARD (default).

Canned ACL

PRIVATE (default) access control list. A canned ACL is a predefined grant.

Add an HTTP > Connector to request the MuleSoft logo from MuleSoft.

Field Value

Field	Value
Display Name	Name for the connector instance. In this example, HTTP > Connector is named `Get MuleSoft logo`.
Configuration	Configuration with the Host as `developer.mulesoft.com`, Protocol as `HTTPS`, and Port as `80`.
URL or Path	`/sites/all/themes/muletheme/images/mulesoft_dev_logo_v2.svg`.
Body	`#[payload]`
Target Value	`#[payload]`

Display Name

Name for the connector instance. In this example, HTTP > Connector is named Get MuleSoft logo.

Configuration

Configuration with the Host as developer.mulesoft.com, Protocol as HTTPS, and Port as 80.

URL or Path

/sites/all/themes/muletheme/images/mulesoft_dev_logo_v2.svg.

Body

#[payload]

Target Value

#[payload]

Drag another Amazon S3 connector to create the requested MuleSoft logo in the selected Amazon S3 Bucket.

Field Value

Field	Value
Display Name	Name of your choice. In this example, the S3 connector is named `Create logo object in S3 bucket`.
Extension Configuration	Global configuration that you created.
Bucket Name	`${config.bucket}`
Key	muledevlogo
Content	`#[payload]`
Canned ACL	PRIVATE (default)
Storage Class	STANDARD (default)

Display Name

Name of your choice. In this example, the S3 connector is named Create logo object in S3 bucket.

Extension Configuration

Global configuration that you created.

Bucket Name

${config.bucket}

Key

muledevlogo

Content

#[payload]

Canned ACL

PRIVATE (default)

Storage Class

STANDARD (default)

Add another Amazon S3 connector to get the newly created MuleSoft logo image object from the bucket:

Field Value

Field	Value
Display Name	Name for the connector instance. In this example the S3 connector is called `Get Image`.
Extension Configuration	Global configuration you create.
Bucket Name	`${config.bucket}`
Key	muledevlogo

Display Name

Name for the connector instance. In this example the S3 connector is called Get Image.

Extension Configuration

Global configuration you create.

Bucket Name

${config.bucket}

Key

muledevlogo

Add another Amazon S3 connector to delete the bucket. Because the delete bucket operation’s return type is void, the payload contains the object returned by the get image operation.

Field Value

Bucket Name

${config.bucket}

Force

True

Field	Value
Bucket Name	`${config.bucket}`
Force	True
