Question

更新：我已将此问题更改为我遇到的具体问题。这是因为Grails 2.0将支持过滤器的单元测试，因此希望文档会更好。

我正在尝试为我设置的过滤器编写单元测试，以便在我的grails应用程序中实现Shiro安全性。我正在使用Grails 1.3.7并且暂时无法使用2.0（如果有的话）这个特定的项目。

我的过滤器背后的想法是我需要匿名访问数字或控制器/操作组合，但保护访问其他组合。我还希望它安全失败，即如果您忘记明确允许访问，则禁止访问。

过滤类

class SecurityFilters {
    def filters = {

        homeAccess(controller: "home", action: "*") {
            before = {

                // Allow all access
                request.accessAllowed = true
            }
        }

        serverAccess(controller: "server", action: "list") {
            before = {

                // Allow all access
                request.accessAllowed = true
            }
        }

        layerAccess(controller: "layer", action: "list|listBaseLayersAsJson|listNonBaseLayerAsJson|showLayerByItsId") {
            before = {

                // Allow all access
                request.accessAllowed = true
            }
        }

        all(uri: "/**") {
            before = {

                // Check if request has been allowed by another filter
                if (request.accessAllowed) return true            

                // Ignore direct views (e.g. the default main index page).
                if (!controllerName) return true

                // Access control by convention.
                accessControl(auth: false)
            }
        }
    }
}

单元测试

import org.codehaus.groovy.grails.plugins.web.filters.FilterConfig

class SecurityFiltersTests extends FiltersUnitTestCase {

    protected void setUp() {
        super.setUp()
    }

    protected void tearDown() {
        super.tearDown()
    }

    void testHomeControllerFilter() {

        checkFilter('homeAccess')
    }

    void testServerControllerFilter() {

        checkFilter('serverAccess')
    }

    void testLayerControllerFilter() {

        checkFilter('layerAccess')
    }

    void testAllFilter() {

        assertTrue "Write tests", false
    }

    void checkFilter(String filterName) {

        FilterConfig filter = initFilter(filterName)
        assertNotNull filterName + " filter should exist", filter
        assertExistsBefore(filterName)

        assertEquals "accessAllowed should be null to start with", null, filter.request.accessAllowed

        // Run filter
        filter.before()

        assertEquals "accessAllowed should be true now", true, filter.request.accessAllowed
    }
}

例外

问题是当运行这些测试时，我得到以下异常：

No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

    at shiro.SecurityFiltersTests.testLayerControllerFilter(SecurityFiltersTests.groovy:65)

此外，我在单元测试中放置了以下行：

println "filter.request: " + filter.request

打印以下内容：

filter.request: org.codehaus.groovy.grails.plugins.testing.GrailsMockHttpServletRequest@2914cca4

所以它似乎肯定是在使用模拟请求对象。

所以，问题。

我是否正确使用FiltersUnitTestCase来执行我的过滤器？

如果是这样的话：

为什么我遇到此异常？

Answer 1

提醒所有人调试规则：继续删除代码，直到找到问题所在的确切行。即使很明显该行没有引起问题。因为：有时它实际上是。

作为调试工作的一部分，我的过滤器中包含以下代码：

println "controllerName = '${controllerName}', actionName = '${actionName}'"

这是直接在线之前：

request.accessAllowed = true

我已经把它从粘贴到这个问题的代码中拿出来试图保持整洁，但显然我没有尝试在运行测试时将其评论出来。对于那些查看该代码但无法找到问题的人，感到抱歉。你是对的，问题不在我提供的任何代码中。

答案是如果您尝试访问controllerName或actionName变量，则可能会看到此处报告的异常。

解决方案是在执行任何可能引用setControllerName()或setActionName()的过滤器之前，使用FiltersUnitTestCase中的controllerName和actionName方法。

使用FiltersUnitTestCase对Shiro安全过滤器进行单元测试，IllegalStateException
