最满意答案

这应该这样做：

URL url = new URL("http://example.com"); HttpURLConnection connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod("GET"); connection.connect(); int code = connection.getResponseCode(); if (code>=200 && code <= 209){ //... }

This should do it:

URL url = new URL("http://example.com"); HttpURLConnection connection = (HttpURLConnection)url.openConnection(); connection.setRequestMethod("GET"); connection.connect(); int code = connection.getResponseCode(); if (code>=200 && code <= 209){ //... }
