getContent()

Signature

public Blob getContent()

Return Value

Type: Blob

Usage

The content of the returned Blob depends on how the page is rendered. If the page is rendered as a PDF file, it returns the PDF document. If the page isn’t rendered as PDF, it returns HTML. To access the content of the returned HTML as a string, use the toString Blob method. If the Visualforce page has an error, an ExecutionException is thrown.

You can’t use the getContent method in:

• Triggers
• Test methods. If you use getContent in a test method, the test method fails. getContent is treated as a callout in API version 34.0 and later.
• Apex email services

You also can’t use the method to retrieve the output of a different Visualforce page with the same controller and controller extensions. Instead, pass the base URL of the destination page.

1new PageReference(Site.getBaseUrl() + '/apex/VisualforcePageName').getContent();
