Question

Java 测试URL地址是否能正常连接的代码

Answer 1

String url = "你的url地址";

URL uri = new URL(url);
HttpURLConnection conn = (HttpURLConnection) uri.openConnection();
conn.setRequestProperty("Accept-Charset", "utf-8");
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setConnectTimeout(90000);
conn.setReadTimeout(180000);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

OutputStreamWriter osw = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");

这个过程就是请求url跳转的，一般都是post方式，当然，这个可以自己选择get也可以，osw就是请求返回的数据了
