我正在尝试排序SOCKS代理列表,并找出哪些连接和读取时间小于1000毫秒,这是我的代码
for(Proxy p : proxies) {
try {
URLConnection testConnection = testUrl.openConnection(p);
testConnection.setConnectTimeout(TIMEOUT_VALUE);
testConnection.setReadTimeout(TIMEOUT_VALUE);
success.add(p);
} catch(SocketTimeoutException ste) {
System.out.println("Proxy " + p.address().toString() + " timed out.");
}
}
但是,即使我做TIMEOUT_VALUE = 1,他们中的每一个都通过了测试;我究竟做错了什么?谢谢你的帮助.
最佳答案
我假设你的问题是你没有从连接中读取任何内容.如果我将TIMEOUT_VALUE设置得太低,我会得到一个例外.无论我是读取所有响应还是仅读取一行都不会影响结果时间,我想这是因为我在一个数据包中得到了完整的答案.

int TIMEOUT_VALUE = 1000;
try {
URL testUrl = new URL("http://google.com");
StringBuilder answer = new StringBuilder(100000);
long start = System.nanoTime();
URLConnection testConnection = testUrl.openConnection();
testConnection.setConnectTimeout(TIMEOUT_VALUE);
testConnection.setReadTimeout(TIMEOUT_VALUE);
BufferedReader in = new BufferedReader(new InputStreamReader(testConnection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null) {
answer.append(inputLine);
answer.append("\n");
}
in.close();
long elapsed = System.nanoTime() - start;
System.out.println("Elapsed (ms): " + elapsed / 1000000);
System.out.println("Answer:");
System.out.println(answer);
} catch (SocketTimeoutException e) {
System.out.println("More than " + TIMEOUT_VALUE + " elapsed.");
}
