Question

我的GWT前端位于端口8888. REST后端是8080.默认情况下，cookie不起作用。如果我将为请求调用RequestBuilder.setIncludeCredentials（），似乎应该传递cookie。在这种情况下，我需要将DefaultRequestBuilderFactory替换为我自己的实现，因为我需要将cookie发送到服务器。

SecuredRequestBuilderFactory.java：

public class SecuredRequestBuilderFactory extends DefaultRequestBuilderFactory {
    public SecuredRequestBuilderFactory(HttpRequestBuilderFactory httpRequestBuilderFactory, BodyFactory bodyFactory, HeaderFactory headerFactory, UriFactory uriFactory, @RequestTimeout Integer requestTimeoutMs) {
        super(httpRequestBuilderFactory, bodyFactory, headerFactory, uriFactory, requestTimeoutMs);
    }

    @Override
    public <A extends RestAction<?>> RequestBuilder build(A action, String securityToken) throws ActionException {
        RequestBuilder builder = super.build(action, securityToken);
        builder.setIncludeCredentials(true);
        return builder;
    }
}

我已添加到我的gwt.xml：

<replace-with class="com.example.rest.SecuredRequestBuilderFactory">
    <any>
        <when-type-is class="com.gwtplatform.dispatch.rest.client.core.RequestBuilderFactory"/>
        <when-type-is class="com.gwtplatform.dispatch.rest.client.core.DefaultRequestBuilderFactory"/>
    </any>
</replace-with>

我从调试器（带有IDEA插件的Chrome）中发现，SecuredRequestBuilderFactory类没有映射，并且未包含凭据。

那么，任何想法如何使其发挥作用？

我找到了通过REST请求传递所有cookie的解决方案：

<强> SecuredRequestBuilderFactory.java：

public class SecuredRequestBuilderFactory extends DefaultRequestBuilderFactory {

    @Inject
    public SecuredRequestBuilderFactory(HttpRequestBuilderFactory httpRequestBuilderFactory, BodyFactory bodyFactory, HeaderFactory headerFactory, UriFactory uriFactory, @RequestTimeout Integer requestTimeoutMs) {
        super(httpRequestBuilderFactory, bodyFactory, headerFactory, uriFactory, requestTimeoutMs);
    }

    @Override
    public <A extends RestAction<?>> RequestBuilder build(A action, String securityToken) throws ActionException {
        RequestBuilder builder = super.build(action, securityToken);
        builder.setIncludeCredentials(true);
        return builder;
    }
}

<强> MyRestDispatchModule.java：

public class MyRestDispatchModule extends AbstractGinModule {

    static class MyCoreModuleBuilder extends CoreModuleBuilder {
        MyCoreModuleBuilder(BaseRestDispatchModuleBuilder<?> baseBuilder) {
            super(baseBuilder);
            requestBuilderFactory(SecuredRequestBuilderFactory.class);
        }
    }

    static class MyBuilder extends RestDispatchAsyncModule.Builder {
        @Override
        public CoreModuleBuilder core() {
            return new MyCoreModuleBuilder(this);
        }
    }

    @Override
    protected void configure() {
        install(new MyBuilder().build());
    }
}
