Android：使用HttpClient访问HTTP/HTTPS服务器

网络请求类：

public class NetworkConnector {    private static final int TIMEOUT = 10 * 1000;    private static DefaultHttpClient getHttpClient() {        try {            HttpParams params = new BasicHttpParams();            HttpConnectionParams.setConnectionTimeout(params, TIMEOUT);            HttpConnectionParams.setSoTimeout(params, TIMEOUT);            HttpProtocolParams.setUserAgent(params, null);            SchemeRegistry registry = new SchemeRegistry();            registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));            final SslSocketFactory customSSLSocketFactory = SslSocketFactory.getSocketFactory();            customSSLSocketFactory.setHostnameVerifier(SslSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);            registry.register(new Scheme("https", customSSLSocketFactory, 443));            ClientConnectionManager manager = new ThreadSafeClientConnManager(params, registry);            DefaultHttpClient client = new DefaultHttpClient(manager, params);            return client;        } catch (Exception e) {            e.printStackTrace();            return new DefaultHttpClient();        }    }    public synchronized static ResponseInfo execute(String url, byte[] buff, Map<String, String> headers) {        DefaultHttpClient httpClient = getHttpClient();        int responseCode = 0;        InputStream in = null;        try {            HttpPost request = new HttpPost(url);            if (headers != null && !headers.isEmpty()) {                Iterator it = headers.keySet().iterator();                String key = null;                while (it.hasNext()) {                    key = it.next().toString();                    request.setHeader(key, headers.get(key));                }            }            request.setHeader("Content-Type", "application/octet-stream; charset=utf-8");            HttpEntity entity = new ByteArrayEntity(buff);            request.setEntity(entity);            HttpResponse response = httpClient.execute(request);            responseCode = response.getStatusLine().getStatusCode();            if (responseCode == 200 || responseCode == 201) {                InputStream resIn = response.getEntity().getContent();                int len = (int) response.getEntity().getContentLength();                if (resIn != null && len > 0) {                    BufferedInputStream bufIn = new BufferedInputStream(resIn);                    byte[] data = new byte[len];                    bufIn.read(data, 0, len);                    return new ResponseInfo(0, getHeaders(response.getAllHeaders()), data);                }            }        } catch (Exception e) {            e.printStackTrace();            if (responseCode != 200) {                try {                    if (in != null) {                        in.close();                    }                    httpClient.getConnectionManager().shutdown();                } catch (IOException e1) {                    e1.printStackTrace();                }            }        } finally {            try {                if (in != null) {                    in.close();                }                httpClient.getConnectionManager().shutdown();            } catch (IOException e) {                e.printStackTrace();            }        }        return null;    }    private static Map<String, String> getHeaders(Header[] headerArr) {        Map<String, String> headerMap = new HashMap<>();        if (headerArr != null) {            for (Header header : headerArr) {                headerMap.put(header.getName(), header.getValue());            }        }        return headerMap;    }}

处理网络请求的子线程：

public class RequestRunnable implements Runnable {    private BaseRequest.RequestCallback listener;    private byte[] buf;    private String urlString;    private boolean isRun;    private Map<String, String> headers;    private int apiId;    public RequestRunnable(int apiId, String urlString, byte[] buf, Map<String, String> headers, BaseRequest.RequestCallback listener) {        this.isRun = true;        this.urlString = urlString;        this.buf = buf;        this.headers = headers;        this.listener = listener;        this.apiId = apiId;    }    public void cancelRequest() {        this.isRun = false;    }    @Override    public void run() {        ResponseInfo response = NetworkConnector.execute(urlString, this.buf, headers);        if (response != null) {            response.apiId = apiId;        }        if (isRun) {            Message msg = new Message();            msg.obj = response;            msg.what = 1;            mHandler.sendMessage(msg);        }    }    private Handler mHandler = new Handler(Looper.getMainLooper()) {        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            switch (msg.what) {                case 1:                    if (msg.obj != null) {                        listener.onResponse((ResponseInfo) msg.obj);                    } else {                        listener.onErrorResponse(apiId);                    }                    break;            }        }    };}

线程池工具类：

public class ThreadPoolUtil {    private static int CORE_POOL_SIZE = Runtime.getRuntime().availableProcessors() + 1;    private static int MAX_POOL_SIZE = CORE_POOL_SIZE * 2 + 1;    private static int KEEP_ALIVE_TIME = 60 * 10;    private static BlockingQueue<Runnable> workQueue = new LinkedBlockingQueue<>(128);    private static ThreadPoolExecutor threadPool;    private ThreadPoolUtil() {    }    static {        threadPool = new ThreadPoolExecutor(CORE_POOL_SIZE, MAX_POOL_SIZE, KEEP_ALIVE_TIME, TimeUnit.SECONDS, workQueue, new ThreadFactory() {            private final AtomicInteger integer = new AtomicInteger();            @Override            public Thread newThread(Runnable r) {                return new Thread(r, "thread:" + integer.getAndIncrement());            }        });    }    public static void execute(Runnable runnable) {        threadPool.execute(runnable);    }}

调用：

/** * 调用 * @param apiId 接口id * @param url 服务器url * @param buf 需要上传的字节数组 */protected final void requestData(int apiId, String url, byte[] buf) {    ThreadPoolUtil.execute(new RequestRunnable(apiId, url, buf, getHeaders(), this));}
