The Request object $content property is a Sapien\Request\Content object.
The Content object has these readonly properties:
?string $body: The content body; see below for the value of this property.
?string $charset: The charset parameter value of $headers['content-type'], if any.
?int $length: The value of $headers['content-length'], if any.
?string $md5: The value of $headers['content-md5'], if any.
?string $type: The value of $headers['content-type'], if any, minus any parameters.
When the $body property is null, Content will read from php://input
instead:
$request = new Request();
$body = $request->content->body; // returns `file_get_contents('php://input')`
If you want to provide a custom content body string instead, pass it as a Request argument ...
$request = new Request(
content: 'custom-php-input-string'
);
... or pass an entire Content object of your own construction:
$body = 'custom-php-input-string';
$request = new Request(
content: new Request\Content(
body: $body,
length: strlen($body),
type: 'text/plain',
charset: 'utf-8',
md5: md5($body),
)
);
Note that the $headers values are not modified when you pass in custom content
bodies or objects.
