getAttribute
```
public Object getAttribute(String name)
```
Description copied from interface: jakarta.servlet.ServletRequest

Returns the value of the named attribute as an Object, or null if no attribute of the given name exists.
Attributes can be set two ways. The servlet container may set attributes to make available custom information about a request. For example, for requests made using HTTPS, the attribute jakarta.servlet.request.X509Certificate can be used to retrieve information on the certificate of the client. Attributes can also be set programmatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.
Attribute names should follow the same conventions as package names. Names beginning with jakarta.* are reserved for use by the Jakarta EE platform.

Specified by:

getAttribute in interface ServletRequest

Parameters:

name - Name of the request attribute to return

Returns:

the specified request attribute if it exists; otherwise, return null.

getContentLengthLong
```
public long getContentLengthLong()
```
Description copied from interface: jakarta.servlet.ServletRequest

Returns the length, in bytes, of the request body and made available by the input stream, or -1 if the length is not known. For HTTP servlets, same as the value of the CGI variable CONTENT_LENGTH.

Specified by:

getContentLengthLong in interface ServletRequest

Returns:

a long integer containing the length of the request body or -1 if the length is not known

getAttributeNames
```
public Enumeration<String> getAttributeNames()
```
Return the names of all request attributes for this Request, or an empty Enumeration if there are none. Note that the attribute names returned will only be those for the attributes set via setAttribute(String, Object). Tomcat internal attributes will not be included although they are accessible via getAttribute(String). The Tomcat internal attributes include:
- Globals.DISPATCHER_TYPE_ATTR
- Globals.DISPATCHER_REQUEST_PATH_ATTR
- Globals.ASYNC_SUPPORTED_ATTR

IOException - if an input/output error occurs

getLocale
```
public Locale getLocale()
```
Description copied from interface: jakarta.servlet.ServletRequest

If you use this method with a multivalued parameter, the value returned is equal to the first value in the array returned by getParameterValues.
If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via ServletRequest.getInputStream() or ServletRequest.getReader() can interfere with the execution of this method.

Specified by:
