gxRest
The gCube eXtensions to the Rest Protocol (gxRest) is a set of Java libraries designed to provide convenient round-trip interaction between a Restful web application (also known as "service") and its clients.
gxRest has the flexibility for different degrees of exploitation:
- it can be entirely adopted both at client and service side with full benefit of its conventions;
- it can be used to send REST requests based only on plain HTTP;
- it can be used only to return HTTP code/messagess from the service;
- it can be used only to throw Exceptions from the service to the client.
Examples of use
Sending a request:
GXHTTPRequest request = GXHTTPRequest.newRequest("http://host:port/service/").from("GXRequestTest");
//prepare some parameters
String context ="...";
Map<String,String> queryParams = new WeakHashMap<>();
queryParams.put("param name", "param value");
GXInboundResponse response = request.path("context")
.queryParams(queryParams).withBody(context).post();
Returning a success response:
@POST
public Response create(...) {
//Resource successfully created
URI location = ... //URI of the new resource
return GXOutboundSuccessResponse.newCREATEResponse(location)
.withMessage("Resource successfully created.")
.ofType(MediaType.APPLICATION_JSON)
.build();
}
Throwing an exception:
@POST
public Response create(...) {
//Oh no, something failed here
GXOutboundErrorResponse.throwException(new MyCustomException("Resource already exists."));
}
Parsing a response
// invoke the remote method and get a response.
GXInboundResponse response = ...;
if (response.hasException())
throw response.getException();
//assuming a created (200) code was expected
if (response.hasCREATEDCode()) {
System.out.println("Resource successfully created!");
}
//access content as string
String value = response.getStreamedContentAsString();
//unmasharll content as json
Context returnedContext = response.tryConvertStreamedContentFromJson(Context.class);
