Protect REST URL with same path and different http methods - rest

I have a situation that I need some assistance with. I have four REST URL with same path and different http methods
/api/users/** GET,POST,PUT,DELETE
I want to use Shiro to protoct the PUP, POST, DELETE and keep GET is anonymous. I configured the following URLs but with out luck
/api/users/** =rest[user:update,user:delete,user:create]
/api/users/** =anon

Maybe you could do something like this:
/api/users/**=rest[user]
Then, it kind of depends on how you are creating the REST APIs. With a JAX-RS implementation, like Jersey for example, you could do the following:
#Path("/api/users")
public class SomeResource {
#RequiresPermissions("user:read")
#GET
public Response getResource() {..}
#RequiresPermissions("user:create")
#PUT
public Response putResource() {..}
#RequiresPermissions("user:update")
#POST
public Response postResource() {..}
#RequiresPermissions("user:delete")
#DELETE
public Response deleteResource() {..}
}
This is assuming that you are going with the Annotations based authorization. You could also use the SecurityUtils.getSubject() mechanism.

How to Pass object to REST Get Method

I am using Jersey Rest implementation. There are one Rest Services Called HelloWorld. See the below code.
Please consider this code as reference not as compiled code.
#Path("helloWorld")
public class HelloWorld{
#Path("test")
#Produces(...)
#Consum(...)
#GET
public Response test(Person person){
System.out.println(person);
}
}
I am using Jersey client to sent the request.
Here My question is apart from POST method is there any way to send the object to GET method directly. Instead of QueryString.
Please let me if there is any way to do so.
Thanks
So the problem shouldn't be with the server. I did a few tests on different servers (not weblogic as I don't use it) and all of them seem to have no problems accepting a body in the GET request. The problem seem to be with the client. To test I used the following code
ClientBuilder.newClient()
.target("http://localhost:8080/api/get-body")
.property(ClientProperties.SUPPRESS_HTTP_COMPLIANCE_VALIDATION, true)
.request()
.method(HttpMethod.GET, Entity.text("Hello World"));
The SUPPRESS_HTTP_COMPLIANCE_VALIDATION allows us to pass a body to the request. If we didn't use this, then we would get an error.
The problem with this code, is that even though we set this override property, the client completely overrides the GET method and automatically makes it a POST method, so I would get back a 405 Method Not Allowed.
The solution I came up with is to just allow the client to set a header, e.g. X-GET-BODY-OVERRIDE, and then use a #PreMatching filter on the server side to check for this header. If the header is present, then just change the method to a GET
#Provider
#PreMatching
public class GetWithBodyFilter implements ContainerRequestFilter {
#Override
public void filter(ContainerRequestContext request) throws IOException {
String getOverride = request.getHeaderString("X-GET-BODY-OVERRIDE");
if (getOverride != null && "true".equalsIgnoreCase(getOverride)) {
request.setMethod(HttpMethod.GET);
}
}
}
Then just register the filter with the server side. On the client, you would simply need to add the header
ClientBuilder.newClient()
.target("http://localhost:8080/api/get-body")
.property(ClientProperties.SUPPRESS_HTTP_COMPLIANCE_VALIDATION, true)
.request()
.header("X-GET-BODY-OVERRIDE", "True")
.method(HttpMethod.GET, Entity.text("Hello World"));
This solution is good because it takes into account more than just the Jersey client, in regards with being able to send a body in the GET request.

PathParam Layer check REST

First of all have a nice weekend for those who are! For the other good luck :)
I am creating an app using rest architecture.
I just have a simple question but I don't know how to explain it.
So let's take an example and maybe the question will come after.
Imagine you have a path element called Car. If I do a GET on it it returns the carInformation
So I would define:
#GET
#Path("/car/{carid}/display")
public Response getCar(#PathParam("carid")String carID)
If I define actions to perform on this car like open, close, start etc:
#POST
#Path("/car/{carid}/startup")
public Response startup(#PathParam("carid")String carID)
#POST
#Path("/car/{carid}/open")
public Response open(#PathParam("carid")String carID)
#POST
#Path("/car/{carid}/close")
public Response close(#PathParam("carid")String carID)
Is there a common check done at /car/{carid} like "is it my car?" "is it in the garage?" or do I have to implement it with abstraction for example between the process which will be called after
In fact I am not understanding the real goal of path param. Why don't do simply
#GET
#Path("/car/displayCar")
public Response getCar(#QueryParam("carid")String carID)
#POST
#Path("/car/startup")
public Response startup(String carID)
#POST
#Path("/car/{carid}/open")
public Response open(String carID)
#POST
#Path("/car/{carid}/close")
public Response close(String carID)
Thanks all for you answer in advance
Best regards

There are a lot of ways to go at this, both REST and RPC - and I'm not here to say which is better (you need to evaluate which would be easier/better/etc for the consumers of your API [IMO]). For this I am going to go at it using a REST approach.
For displaying a single car's info there is no need for an endpoint ending in 'display'. A GET request to /car/{car id} is sufficient. That document can have things like the car's current state (open, closed, running, exploded, etc . . .) The GET is your action, the /car/{car id} is your thing, and the document it returns (and excepts via POST or PUT are the protocol of your API)

Complex (non string) return type for Jersey REST method

I'm having trouble setting something up that I'm pretty sure /should/ be easy, so I thought I'd throw it to the crowd. I can't seem to find what I'm looking for elsewhere on the web or on SE.
I am simplifying my project of course, but basically I have a JAX-WS annontated Jersey resource class that looks something like this:
#Path("myresource")
public class MyResource {
#Autowired
MyComplexObjectDAO daoInstance;
#Path("findObject/{id}")
#GET
public MyComplexObject findObject( #PathParam(value="id") String id ) {
return daoInstance.findObject( id );
}
#Path("saveObject")
#PUT
public MyComplexObject saveObject( MyComplexObject objectToSave ) {
MyComplexObject savedObject = daoInstance.saveObject( objectToSave );
return savedObject;
}
}
So you can see I'm autowiring a DAO object using spring, and then I use the DAO methods in the REST handlers.
The 'findObject' call seems to work fine - so far it works exactly as I expect it to.
The 'saveObject' call is not working the way I want and that's what I need some advice on.
You can see that I'm trying to directly take an instance of my complex object as a parameter to the REST method. Additionally I would like to return an instance of the complex object after it's been saved.
I put together some 'client' code for testing this out.
#Test
public void saveTest() {
WebResource wsClient = createWebServiceClient();
MyComplexObject unsavedInstance = createMyComplexObject();
MyComplexObject savedInstance =
wsClient
.path("saveObject")
.accept(MediaType.APPLICATION_XML)
.put(MyComplexObject.class, unsavedInstance);
assertNotNull(savedIntent);
}
Which is returning the following error:
com.sun.jersey.api.client.UniformInterfaceException: PUT http://localhost:8081/rest/myresource/save returned a response status of 400 Bad Request
I don't see why this isn't working and I think I've tried just about everything I can think of. Any help or direction would be very much appreciated.
Thanks so much!
I see that you call the accept() method in your test client (which means that a "Accept:" header is added to the request, indicating the server what type of representation you would like). However, you don't call the type() method to add a "Content-type:" header and inform the server that you are sending XML data. See http://jersey.java.net/nonav/documentation/latest/client-api.html#d4e644 for examples.
Side remark: your URLs are not RESTful - you should avoid verbs in your path:
So, instead of:
/api/findObject/{id}
/api/saveObject
You should use:
/api/objects/{id}
/api/objects
Last note: to create an object on calling /api/objects, you should do a POST and not a PUT to adhere to REST best practices and widely adopted patterns.
switching to the 'concrete class' solution I alluded to in my earlier comment is what fixed things up for me.

create a Jax-RS RESTful service that accepts both POST and GET?

I'm converting one of my existing service to become RESTful and I've got the basic things working with RestEasy. Some of my client apps should be able to execute both GET and POST requests to several services. I'm just seeking if there is any easy way around jax-rs to specify that API should accept both GETs and POSTs. Following you can find a test method, let me know if you see any way around without duplicating this in another class with #GET and #QueryParam.
#POST
#Path("/add")
public Response testREST(#FormParam("paraA") String paraA,
#FormParam("paraB") int paraB) {
return Response.status(200)
.entity("Test my input : " + paraA + ", age : " + paraB)
.build();
}
Just put your method body in another method and declare a public method for each HTTP verb:
#Controller
#Path("/foo-controller")
public class MyController {
#GET
#Path("/thing")
public Response getStuff() {
return doStuff();
}
#POST
#Path("/thing")
public Response postStuff() {
return doStuff();
}
private Response doStuff() {
// Do the stuff...
return Response.status(200)
.entity("Done")
.build();
}
}
As wikipedia says, an API is RESTful if it is a collection of resources with four defined aspects:
the base URI for the web service, such as http://example.com/resources/
the Internet media type of the data supported by the web service. This is often XML but can be any other valid Internet media type providing that it is a valid hypertext standard.
the set of operations supported by the web service using HTTP methods (e.g., GET, PUT, POST, or DELETE).
The API must be hypertext driven.
By diminishing the difference between GET and POST you're violating the third aspect.
If this scenario fits for all your resources you could create a ServletFilter which wraps the request and will return Get or Post everytime the method will be requested.

adding http headers in call to SoapHttpClient service

I have to consume a service provided by one of our partners. I was given little direction, but was told the security was to be PasswordDigest. I looked it up and immediatly saw lots of references to WSE, so off I went. It was very easy to implement and in no time I had a standard WSE user token using PasswordDigest sitting in the SOAP headers of my messages.
When we started testing today I was immediatly told (by the error message) that things weren't right. Turns out, out partner doesn't look in the SOAP header, but rather wants the security info in the http header.
I have seen lots of articles on how to add custom http headers to a proxy class, but my proxy inherits from SoapHttpClientProtocol which doesn't have a headers collection to add to. I was looking at making a raw httpWebRequest, but I have a specific method to access that has some complex parameters to deal with (and besides it feels like going backwords).
What is the best way to add custom http headers to a service proxy class that doesn't have a GetWebRequest method?
For reference:
Proxy class decleration:
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Web.Services", "2.0.50727.3053")]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Web.Services.WebServiceBindingAttribute(Name="MtomServiceSoap11", namespace="http://ws.xxxxxxx.com/")]
public partial class MtomServiceService : System.Web.Services.Protocols.SoapHttpClientProtocol {
Target method I need to call:
[System.Web.Services.Protocols.SoapDocumentMethodAttribute("", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Bare)]
[return: System.Xml.Serialization.XmlElementAttribute("uploadDocumentResponse", Namespace="http://ws.edsmtom.citizensfla.com/")]
public uploadDocumentResponse uploadDocument([System.Xml.Serialization.XmlElementAttribute(Namespace="http://ws.xxxxxxx.com/")] uploadDocumentRequest uploadDocumentRequest) {
object[] results = this.Invoke("uploadDocument", new object[] {
uploadDocumentRequest});
return ((uploadDocumentResponse)(results[0]));
}
}
The actual call to the Service is simple. The objects being pass in are not:
request.criteria = docCriteria;
request.document = document;
var result = service.uploadDocument(request);
Thanks.
It figures that 30 minutes after posting I would stumble across the answer. While the proxy class decelaration does not create a GetWebRequest method, its base class System.Web.Services.Protocols.SoapHttpClientProtocol has it and it can be overridden.
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
var request = base.GetWebRequest(uri);
request.Headers.Add("blah", "blah"); // <----
return request;
}
