让HttpDefaultClient很慢的execute（）

问题描述

我与HttpDefaultClient的execute（）方法的执行方法，大量的性能问题。

I have massive performance problems with the execute method of the execute() method of the HttpDefaultClient.

我目前使用这种将数据发布到服务器，接收JSON和反序列化的数据。呼叫拿我的手机上787-8到30秒。如果我切换到无线（它的pretty快，相同的呼叫需要300ms的我的电脑）需要3秒8秒。至少90％的，时间是在执行方法花费。

I'm currently using this to post data to a Server, receiving JSON and deserialize the data. A call takes 8s to 30s on my phone. If I switch to Wifi (it's pretty fast, the same call takes 300ms on my PC) it takes 3s to 8s. At least 90% of that time is spend in the execute method.

时使用code：

    HttpPost post = new HttpPost(DEST_URL);
    HashMap<String, String> params = req.getPostParams();
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

    for (String key : params.keySet()) {
        nameValuePairs.add(new BasicNameValuePair(key, params.get(key)));
    }

    post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    post.setHeader(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
    HttpResponse response = httpClient.execute(post); // very slow!

    return response;

我们还开发了iOS应用，它能够在1做同样的2秒。是否有针对http更快的方法（在未来HTTPS）？

We also develop an iOS app which is able to do the same within 1 to 2s. Is there a quicker way for http (https in the future)?

创建客户端是这样的：

        HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER;
        final SSLSocketFactory socketFactory = SSLSocketFactory
                .getSocketFactory();
        socketFactory
                .setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", socketFactory, 443));
        HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

        HttpClient client = new DefaultHttpClient(params);

应用：HTC野火的Andr​​oid 2.2.1

Using: HTC Wildfire, Android 2.2.1

推荐答案

$ C $以上的CS正常工作。

codes above works fine.

如果我创建一个HttpClient的方式如​​下：

if i create an httpclient the following way:

        DefaultHttpClient httpClient = new DefaultHttpClient();
    // httpclient
    httpClient.getParams().setParameter(
            CoreConnectionPNames.CONNECTION_TIMEOUT, mConnectionTimeOut);
    httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,
            mSocketTimeOut);

首次发布数据到服务器并得到响应时，它花了我10--20秒。

for first time to post data to server and got response , it cost me 10--20 seconds.

但如果我创建一个HttpClient的按照上面的答案。
   当第一次发布数据到服务器并得到响应，它的成本只有4秒钟，我认为它工作正常。

but if i create an HttpClient following the answer above. when first time to post data to server and got response , it cost just 4 seconds,and i think it works fine .
