我认为您的问题是您没有从连接中读取任何内容.如果我将 TIMEOUT_VALUE
设置得太低,则会出现异常.无论我阅读所有响应还是仅阅读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.
I assume your problem is you don't read anything from connection. If I set TIMEOUT_VALUE
too low, I get an exception. Whether I read all response or only one line did not affect the resulting time, I guess it is because I got whole answer in one packet.
这是我使用的测量(没有代理):
Here is the measurement I used (without proxies):
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("
");
}
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.");
}
