HttpClient中URI和URL之间的区别是什么

Question

在下面的示例代码中，uri何时不等于url？

HttpClient client = new DefaultHttpClient();
String url = "http://domain/path1/path2"
HttpGet get = new HttpGet(toFetchURL);
HttpResponse response = client.execute(get);

String uri = get.getURI.toString();
if (!uri.equals(url)) {
    // when would this happen?
    // some logic
}

Answer 1

URL是URI的子集。所以URL可以转换为URI，但URI不能转换为URL。
