如何使用Java中的Httpunit发送Multipart请求

Question

我基本上是问的确切同样的问题在这里.如您所见,没有可靠的答案.我想要做的就是发送一个文件HTTPUnit来测试java servlet.

所以,我有一个Java Servlet这个代码(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");
         ....
    }
}

这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);

当我运行它时,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)

....

我不知道为什么它不会让我添加文件.

有什么建议？？

编辑:

我试图使用本地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>

更新的测试代码:

    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”。

您需要一个网络表单

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});

您确实需要按照第一篇文章的唯一答案中的建议深入研究测试框架文档。

编辑：getPart()ServletRunner 中的 servlet 实现不支持该方法，这就是为什么您无法获得另一侧的任何部分并获得 AbtractMethodError 的原因。
