Question

如何在Apache HttpClient版本4.3.3中设置套接字缓冲区大小？

Answer 1

HttpClient client = new DefaultHttpClient();
client.getParams().setParameter(CoreConnectionPNames.SOCKET_BUFFER_SIZE, 128 * 1024);

    HttpPost post = new HttpPost(url);
    String res = null;
    try
    {
        post.addHeader("Connection", "Keep-Alive");
        post.addHeader("Content-Name", selectedFile.getName());
        post.setEntity(new ByteArrayEntity(fileBytes));
        HttpResponse response = client.execute(post);
        res = EntityUtils.toString(response.getEntity());
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

Answer 2

使用所需的缓冲区大小创建自定义ConnectionConfig对象，并在创建HttpClient对象时将其作为参数传递。例如：

ConnectionConfig connConfig = ConnectionConfig.custom()
        .setBufferSize(DESIRED_BUFFER_SIZE)
        .build();

try (CloseableHttpClient client = HttpClients.custom()
            .setDefaultConnectionConfig(connConfig)
            .build()) {

    HttpGet get = new HttpGet("http://google.com");
    try (CloseableHttpResponse response = client.execute(get)) {
        // Do something with the response
    } catch (IOException e) {
        System.err.println("Error transferring file: " + e.getLocalizedMessage());
    }
} catch (IOException e) {
    System.err.println("Error connecting to server: " + e.getLocalizedMessage());
}

还有许多其他可配置选项，checkout the API表示完整列表。
