DefaultHttpClient 在多个请求上保持活动连接 [英] DefaultHttpClient keep alive connection on multiple requests

问题描述

我正在使用 DefaultHttpClient 通过基本身份验证向同一个 URL 发出大量请求.

I'm using the DefaultHttpClient to make numerous requests to the same URL with basic authentication.

像这样:

for (String json: listOfItems)
{
    DefaultHttpClient client = new DefaultHttpClient();

    try
    {       
       client.getCredentialsProvider().setCredentials(
                    new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM, "basic"),
                    new UsernamePasswordCredentials(user, pass));

       HttpPost request = new HttpPost(path);
       setHeaders(request);

       StringEntity se = new StringEntity(json, HTTP.UTF_8);
       se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, APPLICATION_JSON));
       request.setEntity(se);

       client.execute(request);    
    }       
    finally
    {
       // close/release connection
       client.getConnectionManager().shutdown();            
    }
}

我的问题是在执行此操作时保持连接活动的最佳方法是什么.所以我不需要在每个 post 请求上关闭连接.

My question is what is the best way to keep alive the connection while doing this. So I don't need to close the connection on each post request.

推荐答案

您可能需要添加 Socket_Timeout 参数并实现 KeepAlive 策略，这里有详细说明 -

You might need to add the Socket_Timeout parameter and implement a KeepAlive strategy, which are detailed over here -
