使用Dropwizard

标签: java jackson dropwizard

我正在尝试在我的Dropwizard应用程序中编写一个安全资源的测试(我正在使用Dropwizard 0.8.1)。我运行应用程序时授权正常,但我似乎无法编写一个可行的测试。该代码主要基于示例Hello World应用程序,尽管传递了正确的授权标头,但我仍然获得了401。我有以下内容:

HelloWorldResource

package com.example.helloworld.resources;

import com.example.helloworld.core.Saying;
import com.example.helloworld.core.User;
import com.google.common.base.Optional;
import com.codahale.metrics.annotation.Timed;
import io.dropwizard.auth.Auth;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import java.util.concurrent.atomic.AtomicLong;

@Path("/hello-world")
@Produces(MediaType.APPLICATION_JSON)
public class HelloWorldResource {
    private final String template;
    private final String defaultName;
    private final AtomicLong counter;

    public HelloWorldResource(String template, String defaultName) {
        this.template = template;
        this.defaultName = defaultName;
        this.counter = new AtomicLong();
    }

    @GET
    @Timed
    public Saying sayHello(@QueryParam("name") Optional<String> name) {
        final String value = String.format(template, name.or(defaultName));
        return new Saying(counter.incrementAndGet(), value);
    }

    @GET
    @Path("secure")
    @Timed
    public Saying sayHelloSecurely(@Auth User user) {
        final String value = String.format(template, user.getName());
        return new Saying(counter.incrementAndGet(), value);
    }
}

package com.example.helloworld.core;

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import org.hibernate.validator.constraints.Length;

public class Saying {
    private final long id;

    @Length(max = 3)
    private final String content;

    @JsonCreator
    public Saying(@JsonProperty long id, @JsonProperty String content) {
        this.id = id;
        this.content = content;
    }

    @JsonProperty
    public long getId() {
        return id;
    }

    @JsonProperty
    public String getContent() {
        return content;
    }
}

身份验证

package com.example.helloworld.auth;


import com.example.helloworld.core.User;
import com.google.common.base.Optional;
import io.dropwizard.auth.AuthenticationException;
import io.dropwizard.auth.Authenticator;
import io.dropwizard.auth.basic.BasicCredentials;

public class SimpleAuthenticator implements Authenticator<BasicCredentials, User> {
    public Optional<User> authenticate(BasicCredentials credentials) throws AuthenticationException {
        if ("secret".equals(credentials.getPassword())) {
            return Optional.of(new User(credentials.getUsername()));
        }
        return Optional.absent();
    }
}

SecureTest

package com.example.helloworld.resources;

import com.example.helloworld.auth.SimpleAuthenticator;
import com.example.helloworld.core.Saying;
import com.example.helloworld.core.User;
import io.dropwizard.auth.AuthFactory;
import io.dropwizard.auth.basic.BasicAuthFactory;
import io.dropwizard.testing.junit.ResourceTestRule;
import org.glassfish.jersey.server.filter.RolesAllowedDynamicFeature;
import org.glassfish.jersey.test.grizzly.GrizzlyWebTestContainerFactory;
import org.junit.ClassRule;
import org.junit.Test;

import javax.ws.rs.core.HttpHeaders;

public class SecureHelloWorldResourceTest {
    @ClassRule
    public static final ResourceTestRule resources =
            ResourceTestRule.builder()
                    .addProvider(RolesAllowedDynamicFeature.class)
                    .addProvider(AuthFactory.binder(new BasicAuthFactory<User>(new SimpleAuthenticator(),
                            "Authentication Realm",
                            User.class)))
                    .addResource(new HelloWorldResource("Hey There %s", "DefaultName"))
                    .build();

    @Test
    public void testGetPerson() {
        resources
                .client()
                .target("/hello-world/secure")
                .request()
                .header(HttpHeaders.AUTHORIZATION, "Basic Z29vZC1ndXk6c2VjcmV0").get(Saying.class); //Decodes to "good-guy:secret"

    }
}

更新

阅读https://github.com/dropwizard/dropwizard/issues/922后,我开始使用Grizzly容器,现在我收到了与Saying序列化有关的新错误:

安全测试

package com.example.helloworld.resources;

import com.example.helloworld.auth.SimpleAuthenticator;

    @ClassRule
    public static final ResourceTestRule resources =
            ResourceTestRule.builder()
                    .addProvider(RolesAllowedDynamicFeature.class)
                    .setTestContainerFactory(new GrizzlyWebTestContainerFactory())
                    .addProvider(AuthFactory.binder(new BasicAuthFactory<User>(new SimpleAuthenticator(),
                            "Authentication Realm",

                    .addResource(new HelloWorldResource("Hey There %s", "DefaultName"))
                    .build();

                    .header(HttpHeaders.AUTHORIZATION, "Basic Z29vZC1ndXk6c2VjcmV0").get(Saying.class);

    }
}

答案 0 :(得分:1)

我通过使用命名为JsonProperties的构造函数的params注释来解决更新中的序列化错误,这似乎有点多余。

public class Saying {
    private final long id;

    @Length(max = 3)
    private final String content;

    @JsonCreator
    public Saying(@JsonProperty("id") long id, @JsonProperty("content") String content) {//Note the addition of the ("id") and ("content") 
        this.id = id;
        this.content = content;
    }

    @JsonProperty
    public long getId() {
        return id;
    }

    @JsonProperty
    public String getContent() {
        return content;
    }
}

现在测试看起来像这样:

package com.example.helloworld.resources;

import com.example.helloworld.auth.SimpleAuthenticator;
import com.example.helloworld.core.Saying;
import com.example.helloworld.core.User;
import io.dropwizard.auth.AuthFactory;

import io.dropwizard.testing.junit.ResourceTestRule;
import org.glassfish.jersey.test.grizzly.GrizzlyWebTestContainerFactory;
import org.junit.Assert;
import org.junit.ClassRule;
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.ExpectedException;

import javax.ws.rs.NotAuthorizedException;
import javax.ws.rs.core.HttpHeaders;

public class SecureHelloWorldResourceTest {
    @Rule
    public ExpectedException exception = ExpectedException.none();
    @ClassRule
    public static final ResourceTestRule resources =
            ResourceTestRule.builder()
                    .setTestContainerFactory(new GrizzlyWebTestContainerFactory())
                    .addProvider(AuthFactory.binder(new BasicAuthFactory<User>(new SimpleAuthenticator(),
                            "Authentication Realm",
                            User.class)))
                    .addResource(new HelloWorldResource("Hey There %s", "DefaultName"))
                    .build();

    @Test
    public void testAuthorizedRequest() {
        Saying result = resources
                .getJerseyTest()
                .target("/hello-world/secure")
                .request()
                .header(HttpHeaders.AUTHORIZATION, "Basic Z29vZC1ndXk6c2VjcmV0").get(Saying.class);//good-guy:secret

        Assert.assertEquals("Hey There good-guy", result.getContent());
    }

    @Test
    public void testDeniedRequest() {
        exception.expect(NotAuthorizedException.class);
        resources
                .getJerseyTest()
                .target("/hello-world/secure")
                .request()
                .header(HttpHeaders.AUTHORIZATION, "Basic YmFkLWd1eTpwYXNzd29yZA==").get(Saying.class);//bad-guy:password


    }
}
