Class RestRequest

java.lang.Object
org.apache.juneau.ContextSession
org.apache.juneau.BeanSession
org.apache.juneau.rest.client.RestRequest
All Implemented Interfaces:
AutoCloseable, Configurable, HttpUriRequest, HttpMessage, HttpRequest
Direct Known Subclasses:
MockRestRequest
public class RestRequest extends BeanSession implements HttpUriRequest, Configurable, AutoCloseable
Represents a request to a remote REST resource.

Instances of this class are created by the various creator methods on the RestClient class.

Example:

// Create a request and automatically close it. try (RestRequest req = client.get("/myResource")) { req .queryData("foo", "bar") .run() .assertStatus().asCode().is(200); }

The close() method will automatically close any associated RestResponse if one was created via run().

Notes:
  • This class is not thread safe.
  • This class implements AutoCloseable and can be used in try-with-resources blocks. The close() method allows unchecked exceptions to propagate for debuggability, while catching and logging checked exceptions to follow AutoCloseable best practices.

    • createInnerRequest

      protected HttpRequestBase createInnerRequest(String method, URI uri, boolean hasBody)
      Constructs the HttpRequestBase object that ends up being passed to the client execute method.

    • json5

      public RestRequest json5()
      Convenience method for specifying Simplified JSON as the marshalling transmission media type for this request only.

      Notes:
      • Calling this method multiple times will return the same original response object.
      • You must close the returned object if you do not consume the response or execute a method that consumes the response.
      • If you are only interested in the response code, use the complete() method which will automatically consume the response so that you don't need to call InputStream.close() on the response body.

      Notes:
      Example:

      // Get the response code. // No need to call close() on the RestResponse object. int rc = client.get(URI).complete().getResponseCode();

      Returns:
      The response object.
      Throws:
      RestCallException - If an exception or non-200 response code occurred during the connection attempt.

      public void close()
      Closes this request and its associated response (if one was created).

      This method is idempotent and can be called multiple times without side effects.

      Implementation Notes:

      This implementation represents a compromise between strict AutoCloseable compliance and debuggability:

      • Unchecked exceptions (RuntimeException and Error) from the response close are allowed to propagate. This ensures programming errors and serious issues are visible during development and testing.
      • Checked exceptions (including RestCallException) are caught and logged but not thrown. This follows AutoCloseable best practices and prevents close exceptions from interfering with try-with-resources cleanup or masking the original exception.
