当我取消并请求中止或取消连接时，瞄准使用HttpURLConnection内部停止好的，但仍然发送请求并返回来自服务器的值AsyncTaskAsyncTaskAsyncTaskHttpURLConnection
我怎样才能使HttpURLConnection句号取消所有请求或中止请求？
这是我使用的代码
public static String post_string(String url, String urlParameters) throws IOException
{
HttpURLConnection conn = null;
try {
conn = (HttpURLConnection) new URL(url).openConnection();
} catch (MalformedURLException e) {
Log.e(Logger, "MalformedURLException While Creating URL Connection - " + e.getMessage());
throw e;
} catch (IOException e) {
Log.e(Logger, "IOException While Creating URL Connection - " + e.getMessage());
throw e;
}
conn.setDoOutput(true);
conn.addRequestProperty("User-Agent", "Mozilla/5.0");
conn.setRequestProperty("Accept-Charset", "UTF-8");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
//if has Post inputs
conn.setRequestProperty("Content-Length", Integer.toString(urlParameters.length()));
OutputStream os = null;
System.setProperty("http.keepAlive", "false");
try {
os = conn.getOutputStream();
} catch (IOException e) {
Log.e(Logger, "IOException While Creating URL OutputStream - " + e.getMessage());
throw e;
}
try {
os.write(urlParameters.toString().getBytes());
} catch (IOException e) {
Log.e(Logger, "IOException While writting URL OutputStream - " + e.getMessage());
throw e;
}
InputStream in = null;
try {
in = conn.getInputStream();
} catch (IOException e) {
Log.e(Logger, "IOException While Creating URL InputStream - " + e.getMessage());
throw e;
}
String output = null;
try {
output = slurp(in);
} catch (IOException e) {
Log.e(Logger, "IOException While Reading URL OutputStream - " + e.getMessage());
throw e;
} finally {
try {
os.close();
in.close();
} catch (IOException e) {
Log.e(Logger, "IOException While Closing URL Output and Input Stream - " + e.getMessage());
}
}
conn.disconnect();
Log.i("Server output " , output);
return output;
}
private static String slurp(InputStream in) throws IOException
{
StringBuffer out = new StringBuffer();
byte[] b = new byte[4096];
for (int n; (n = in.read(b)) != -1;) {
out.append(new String(b, 0, n));
}
return out.toString();
}
这就是我用来中止连接的方法
conn.disconnect();
任何建议如何中止？
