Question

我基本上是在问同一个问题here。如您所见，没有可靠的答案。我想要做的就是使用HTTPUnit发送一个文件来测试java servlet。

所以，我有Java Servlet这段代码（dumbed down）：

@WebServlet("/properties/StorePropertyAttachment")
@MultipartConfig
public class StorePropertyAttachment {

    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException{
        final Part p = req.getPart("propertyImage");
         ....
    }
}

以下是我的测试用例的重要部分：

    ServletRunner servletRunner = new ServletRunner();
    servletRunner.registerServlet("StorePropertyAttachment", StorePropertyAttachment.class.getName());

    WebRequest webRequest = new PostMethodWebRequest(WEB_REQUEST_BASE_URL + STORE_PROPERTIES_ENDPOINT);
    UploadFileSpec spec = new UploadFileSpec(new File("C:/test.jpg"), "multipart/form-data");
    webRequest.setParameter("propertyImage", new UploadFileSpec[] {spec});
    ^^^^^  line 68  ^^^^^

    ServletUnitClient servletClient = servletRunner.newClient();
    WebResponse webResponse = servletClient.getResponse(webRequest);

当我运行时，我收到此错误：

com.meterware.httpunit.IllegalNonFileParameterException: Parameter 'propertyImage' is not a file parameter and may not be set to a file value.
    at com.meterware.httpunit.WebRequest.setParameter(WebRequest.java:232)
    at com.amsgeo.mspworkmanager.services.properties.PropertyAttachmentTest.test(PropertyAttachmentTest.java:68)
    ....

只是为了踢，如果我将第68行更改为此（正常参数）：

webRequest.setParameter("propertyImage", "some string");

我得到了这个错误（从我的servlet中我的方式）：

java.lang.AbstractMethodError: com.meterware.servletunit.ServletUnitHttpRequest.getPart(Ljava/lang/String;)Ljavax/servlet/http/Part;
at com.amsgeo.mspworkmanager.services.properties.StorePropertyAttachment.doPost(StorePropertyAttachment.java:40)

at com.amsgeo.mspworkmanager.services.properties.PropertyAttachmentTest.testNoParam(PropertyAttachmentTest.java:70)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
....

我不知道为什么它不会让我添加文件。

有什么建议吗？

编辑：

我正在尝试使用本地html文件中的表单提交此内容。我正在成功加载表单但是我得到了404.这是我的表单声明。

<form method="POST" action="http://localhost/StorePropertyAttachment" enctype="multipart/form-data" name="propertyImageTest">
    <input type="file" name="propertyImage" />
    <input type="submit" />
</form>

更新了测试代码：

    ServletRunner servletRunner = new ServletRunner();
    servletRunner.registerServlet("StorePropertyAttachment", StorePropertyAttachment.class.getName());

    WebConversation conversation = new WebConversation();
    WebRequest  request = new GetMethodWebRequest("file:/C:/test.html");
    WebResponse response = conversation.getResponse(request);
    WebForm form = response.getFormWithName("propertyImageTest");   
    UploadFileSpec uploadFileSpec = new UploadFileSpec(new File("C:/test.jpg"), "image/jpeg"); 
    form.setParameter("propertyImage", new UploadFileSpec[] {uploadFileSpec});

    WebResponse webResponse = form.submit();

Answer 1

第三个UploadFileSpec构造函数参数不应该是内容类型而不是消息类型吗？在你的情况下将是“image / jpeg”。

你需要一个WebForm

WebConversation conversation = new WebConversation();
WebRequest  request = new GetMethodWebRequest("http://your-site-to-test.com/path-to-your-upload-form");
WebResponse response = conversation.getResponse(request);
WebForm form = response.getFormWithName("stockImageUpload");   
UploadFileSpec uploadFileSpec = new UploadFileSpec("test.jpg",new File("C:/test.jpg"), "image/jpeg"); 
form.setParameter("propertyImage", new UploadFileSpec[] {uploadFileSpec});

您确实需要深入了解第一篇文章中唯一答案中建议的测试框架文档。

编辑：ServletRunner中的servlet实现不支持getPart()方法，这就是为什么你不能在另一方获得任何部分并获得AbtractMethodError。
