Since 1.1.0

ZATS Mimic introduces the UploadAgent to simulate file uploading operation with consistent usage. UploadAgent supports single or multiple files uploading as ZK components do.

Upload Files with a Component

The basic way to upload files is using a component such as Fileupload, Button, Menuitem, Toolbarbutton and so on. If we assign the upload attribute to these components, users can click and select a file to upload through the browser dialog, as following image shows:

We can cast these components as a UploadAgent and perform file uploading. Following is a typical example of single file uploading:

@Test
public void test(File file) throws Exception {
	DesktopAgent desktop = Zats.newClient().connect("/upload.zul");
	UploadAgent agent = desktop.query("#btn").as(UploadAgent.class);
	agent.upload(file, null);
	agent.finish();
	agent.upload(file, "text/plain");
	agent.finish();
	FileInputStream is = new FileInputStream(file);
	agent.upload(file.getName(), is, "text/plain");
	agent.finish();
	is.close();
}

• Line 13: Cast component to UploadAgent and keep its reference.
• Line 14: Invoke upload() method to upload a file. We can specify content type through the second argument and null value indicates binary form (application/octet-stream).
• Line 15: Don't forget to invoke finish()method when the uploading is done. Notice that the instance of UploadAgent should be the same one.
• Line 16: It specifies the content of file is a plain text.
• Line 19, 21: The upload(String, InputStream, String) method won't close the input stream, we should close it manually.
