handle	back to summary
public boolean handle(Request request, Response response, Callback callback) throws Exception Overrides org.eclipse.jetty.server.Handler.Wrapper.handle. Implements org.eclipse.jetty.server.Request.Handler.handle. Doc from org.eclipse.jetty.server.Request.Handler.handle. Invoked to handle the passed HTTP request and response. The request is accepted by returning true, then handling must be concluded by completing the passed callback. The handling may be asynchronous, i.e. this method may return true and complete the given callback later, possibly from a different thread. If this method returns false, then the callback must not be invoked and any mutation on the response reversed. Exceptions thrown by this method may be subsequently handled by an error `Request.Handler`, if present, otherwise a default HTTP 500 error is generated and the callback completed while writing the error response. The simplest implementation is: public boolean handle(Request request, Response response, Callback callback) { callback.succeeded(); return true; } A HelloWorld implementation is: public boolean handle(Request request, Response response, Callback callback) { response.write(true, ByteBuffer.wrap("Hello World\n".getBytes(StandardCharsets.UTF_8)), callback); return true; } Parameters request:Request the HTTP request to handle response:Response the HTTP response to handle callback:Callback the callback to complete when the handling is complete Returns:boolean True if and only if the request will be handled, a response generated and the callback eventually called. This may occur within the scope of the call to this method, or asynchronously some time later. If false is returned, then this method must not generate a response, nor complete the callback. Annotations @Override Exceptions Exception: if there is a failure during the handling. Catchers cannot assume that the callback will be called and thus should attempt to complete the request as if a false had been returned.

public boolean handle(Request request, Response response, Callback callback) throws Exception

Overrides org.eclipse.jetty.server.Handler.Wrapper.handle.

Implements org.eclipse.jetty.server.Request.Handler.handle.

Doc from org.eclipse.jetty.server.Request.Handler.handle.

Invoked to handle the passed HTTP request and response.

The request is accepted by returning true, then handling must be concluded by completing the passed callback. The handling may be asynchronous, i.e. this method may return true and complete the given callback later, possibly from a different thread. If this method returns false, then the callback must not be invoked and any mutation on the response reversed.

Exceptions thrown by this method may be subsequently handled by an error Request.Handler, if present, otherwise a default HTTP 500 error is generated and the callback completed while writing the error response.

The simplest implementation is:

public boolean handle(Request request, Response response, Callback callback)
{
    callback.succeeded();
    return true;
}

A HelloWorld implementation is:

public boolean handle(Request request, Response response, Callback callback)
{
    response.write(true, ByteBuffer.wrap("Hello World\n".getBytes(StandardCharsets.UTF_8)), callback);
    return true;
}

Parameters

request:Request: the HTTP request to handle
response:Response: the HTTP response to handle
callback:Callback: the callback to complete when the handling is complete

Returns:boolean

True if and only if the request will be handled, a response generated and the callback eventually called. This may occur within the scope of the call to this method, or asynchronously some time later. If false is returned, then this method must not generate a response, nor complete the callback.

Annotations

@Override

Exceptions

Exception:: if there is a failure during the handling. Catchers cannot assume that the callback will be called and thus should attempt to complete the request as if a false had been returned.

Method Detail

rehandleWelcome back to summary

protected void rehandleWelcome(Request request, Response response, Callback callback, String welcomeTarget) throws Exception

Overrides org.eclipse.jetty.server.ResourceService.rehandleWelcome.

Doc from org.eclipse.jetty.server.ResourceService.rehandleWelcome.

Rehandles the given welcome target.

Implementations should call Handler#handle(Request, Response, Callback) on a Handler that may handle the welcome target differently from the original request.

For example, a request for /ctx/ may be rewritten as /ctx/index.jsp and rehandled from the Server. In this example, the rehandling of /ctx/index.jsp may trigger a different code path so that the rewritten request is handled by a different Handler, in this example one that knows how to handle JSP resources.

Parameters

request:Request: the request
response:Response: the response
callback:Callback: the callback to complete
welcomeTarget:String: the welcome target to rehandle to

Annotations

@Override

Exceptions

Exception:: if the rehandling fails
