java - 类型 SocketFactory 已弃用

Question

我的申请进入绩效审核阶段。所以 Performs 团队告诉我有一些已弃用的方法可用，请编写最新版本。

我的部分代码是:

  private void workAroundReverseDnsBugInHoneycombAndEarlier(HttpClient client) {
    // Android had a bug where HTTPS made reverse DNS lookups (fixed in Ice Cream Sandwich) 
    // http://code.google.com/p/android/issues/detail?id=13117
    SocketFactory socketFactory = new LayeredSocketFactory() {
        SSLSocketFactory delegate = SSLSocketFactory.getSocketFactory();
        @Override 
        public Socket createSocket() throws IOException {
            return delegate.createSocket();
        }
        @Override 
        public Socket connectSocket(Socket sock, String host, int port, InetAddress localAddress, int localPort, HttpParams params) throws IOException {
            return delegate.connectSocket(sock, host, port, localAddress, localPort, params);
        }
        @Override 
        public boolean isSecure(Socket sock) throws IllegalArgumentException {
            return delegate.isSecure(sock);
        }
        @Override 
        public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException {
            injectHostname(socket, host);
            return delegate.createSocket(socket, host, port, autoClose);
        }
        private void injectHostname(Socket socket, String host) {
            try {
                Field field = InetAddress.class.getDeclaredField("hostName");
                field.setAccessible(true);
                field.set(socket.getInetAddress(), host);
            } catch (Exception ignored) {
            }
        }
    };
    client.getConnectionManager().getSchemeRegistry().register(new Scheme("https", socketFactory, 443));
}

这里 SocketFactory ,LayeredSocketFactory,SSLSocketFactory,HttpProtocolParams ... 说

Multiple markers at this line
- The method getParams() from the type HttpClient is deprecated
- The method setUserAgent(HttpParams, String) from the type HttpProtocolParams is 
 deprecated

另一个示例已弃用

- The type LayeredSocketFactory is deprecated
- The type SSLSocketFactory is deprecated
- The type SSLSocketFactory is deprecated

- The type SSLSocketFactory is deprecated

请指导我。我正在使用 HttpClient 4.3.jar 文件。

请告诉我任何想法...

Answer 1

HttpClient 类型的 getParams() 方法已弃用

在 4.3.2 之前，您可以使用 getParams() 方法(现已弃用)向客户端设置参数，在 4.3.2 之后，您可以通过 RequestConfig< 设置请求参数 使用 Builder

的类

Builder requestConfigBuilder = RequestConfig.custom();
requestConfigBuilder.setConnectionRequestTimeout(1000).setMaxRedirects(1);

然后仅设置为 HttpMethod(不像以前那样设置为客户端)

HttpGet request = new HttpGet(builder.build());
request.setConfig(requestConfigBuilder.build());

HttpProtocolParams 类型的方法 setUserAgent(HttpParams, String) 已弃用

CloseableHttpClient httpclient = HttpClients.custom().setUserAgent("Agent").build();

HttpProtocolParams 类型的方法 setContentCharset(HttpParams, String) 已弃用

使用AbstractHttpEntity子类(BasicHttpEntity、ByteArrayEntity、EntityTemplate、FileEntity、InputStreamEntity、SerializableEntity、StringEntity)

HttpPost post = new HttpPost("http://");
post.setEntity(new StringEntity("content", "UTF-8"));

HttpProtocolParams 类型已弃用

(4.3) 使用提供的配置类 'org.apache.http.config' 和 'org.apache.http.client.config'

Builder requestConfigBuilder = RequestConfig.custom();

SocketFactory 类型已弃用 & LayeredSocketFactory 类型已弃用

SSLContext sslcontext = SSLContexts.createSystemDefault();

// Allow TLSv1 protocol only
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        sslcontext,
        new String[] { "TLSv1" },
        null,
        SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);

或

SSLContext sslContext = SSLContexts.custom()
        .useTLS()
        .loadTrustMaterial(myTrustStore)
        .build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);

然后

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();

可以看看HttpClient Tutorial (4.3.x)更多示例和解释

希望对你有帮助
