java - 在 Play 2.0 FakeRequest 中测试 MultipartFormData

Question

我正在尝试为 Play 2 Controller 创建一个功能测试，它将多部分表单数据作为输入。目前 FakeRequest 中没有支持多部分表单 POST 的方法。还有什么其他方法可以测试这个 Controller ？

Map<String, Object> map = new HashMap<String, Object>();
map.put("param1", "test-1");
map.put("param2", "test-2");
map.put("file", file)
Result result = routeAndCall(fakeRequest(POST, "/register").withFormUrlEncodedBody(map));// NO SUCH METHOD

编辑:这是我为测试多部分所做的解决方法。

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://localhost:3333/blobupload");

    FileBody imageFile = new FileBody(new File("test/resources/test-1.jpg"));
    StringBody guid1 = null;
    StringBody guid2 = null;
    try {
        guid1 = new StringBody("GUID-1");

    } catch (UnsupportedEncodingException e1) {
        e1.printStackTrace();
    }

    MultipartEntity reqEntity = new MultipartEntity();
    reqEntity.addPart("key1", imageFile);
    reqEntity.addPart("key2", guid1);

    httppost.setEntity(reqEntity);

    HttpResponse response;
    try {
        response = httpclient.execute(httppost);
        HttpEntity resEntity = response.getEntity();

        assertThat(response.getStatusLine().getStatusCode()).isEqualTo(200);
    } catch (ClientProtocolException e) {
        e.printStackTrace();
} catch (IOException e) {
        e.printStackTrace();
}

你应该使用 callAction 来使用 withFormUrlEncodedBody

@Test
public void testMyAction() {
    running(fakeApplication(), new Runnable() {
        public void run() {                
            Map<String,String> data = new HashMap<String, Object>();
            data.put("param1", "test-1");
            data.put("param2", "test-2");
            data.put("file", file);

            Result result = callAction(
                controllers.whatever.action(),
                fakeRequest().withFormUrlEncodedBody(data)
            )
            ...
         }
     }
}

我只将 Scala api 用于 Play Framework 2，但我认为您不能使用 withFormUrlEncodedBody 测试多部分表单。

在 Scala 中你可以这样做:

import play.api.libs.Files._
import play.api.mvc.MultipartFormData._

class MyTestSpec extends Specification {

    "mytest should bla bla bla" in {
        running(FakeApplication(aditionalConfiguration = inMemoryDatabase())) {
            val data = new MultipartFormData(Map(
                ("param1" -> Seq("test-1")),
                ("param2" -> Seq("test-2"))
            ), List(
                FilePart("payload", "message", Some("Content-Type: multipart/form-data"), play.api.libs.Files.TemporaryFile(new java.io.File("/tmp/pepe.txt")))
    ), List(), List())

            val Some(result) = routeAndCall(FakeRequest(POST, "/route/action", FakeHeaders(), data))
            ...
        }
    }
}

我猜你可以将它翻译成 Java，抱歉，我不知道如何用 Java 编写代码。
