我正在非常频繁地(> = 1 /秒)对API端点进行HTTP POST,我想确保我正在有效地进行操作。我的目标是尽快成功或失败,特别是因为我有单独的代码来重试失败的POST。有一个不错的页面HttpClient performance tips,但我不确定是否全面实施它们都会带来真正的好处。这里是我的代码现在:如何有效地重用HttpClient连接?
public class Poster {
private String url;
// re-use our request
private HttpClient client;
// re-use our method
private PostMethod method;
public Poster(String url) {
this.url = url;
// Set up the request for reuse.
HttpClientParams clientParams = new HttpClientParams();
clientParams.setSoTimeout(1000); // 1 second timeout.
this.client = new HttpClient(clientParams);
// don't check for stale connections, since we want to be as fast as possible?
// this.client.getParams().setParameter("http.connection.stalecheck", false);
this.method = new PostMethod(this.url);
// custom RetryHandler to prevent retry attempts
HttpMethodRetryHandler myretryhandler = new HttpMethodRetryHandler() {
public boolean retryMethod(final HttpMethod method, final IOException exception, int executionCount) {
// For now, never retry
return false;
}
};
this.method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER, myretryhandler);
}
protected boolean sendData(SensorData data) {
NameValuePair[] payload = {
// ...
};
method.setRequestBody(payload);
// Execute it and get the results.
try {
// Execute the POST method.
client.executeMethod(method);
} catch (IOException e) {
// unable to POST, deal with consequences here
method.releaseConnection();
return false;
}
// don't release so that it can be reused?
method.releaseConnection();
return method.getStatusCode() == HttpStatus.SC_OK;
}
}
是否有意义,禁用旧的连接检查?我应该看看使用MultiThreadedConnectionManager?当然,实际的基准测试会有所帮助,但我想检查我的代码是否在正确的轨道上。
尽管没有答案,但我赢得了热门问题徽章(1000多个视图),这很具有讽刺意味。如果你有一些建议,回答这个问题可能是赢得声誉的好方法。 ;-) – pr1001
