Question

我能够连接到帐户，我也能够创建和访问容器。但是当我尝试使用JOSS库上传对象时，我得到以下异常。文件名是否必须是执行代码的本地计算机上的文件？我认为这将是服务器上的文件名，它将存储在特定容器下。

// Source Code
    public void addObject(String containerName,String objectName,String object) {
        Container container = account.getContainer(containerName);
        StoredObject storedObject = container.getObject(object);
        storedObject.uploadObject(new File(objectName));
    }

// TestCode
@Test
    public void testAddObject() {
        SwiftHandlerFactory instance = SwiftHandlerFactory.getInstance();
        SwiftHandler handler = null;
        try {
            handler = instance.getSwiftHandler(SwiftHandlerType.SwiftJossHandler, propertiesFile);
            handler.addObject("test_container", "/test_object", "Some random data");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

uploadObject有很多变化，我试图在这里上传一个字符串，但它试图在我的本地磁盘上找到一个文件。我将其更改为使用另一个使用byte []的方法。

public void addObject(String containerName,String objectName,String object) {
    Container container = account.getContainer(containerName);
    if(!container.exists())
        container.create();
    StoredObject storedObject = container.getObject(objectName);
    storedObject.uploadObject(object.getBytes());
}
