本文介绍了OkHttp 3.11.0版本的EventListener接口，用于监测网络请求的各个阶段，包括DNS解析、连接建立、TLS安全连接等。通过自定义EventListener，可以详细统计每个请求的耗时和状态，提升网络监控能力。

OkHttp 之网络请求耗时统计

OkHttp 3.11.0版本提供了EventListener接口，可以让调用者接收一系列网络请求过程中的事件，例如DNS解析、TSL/SSL连接、Response接收等。通过继承此接口，调用者可以监视整个应用中网络请求次数、流量大小、耗时情况。
使用方法如下：

 public class HttpEventListener extends EventListener {
   
   

    /**
     * 自定义EventListener工厂
     */
    public static final Factory FACTORY = new Factory() {
        final AtomicLong nextCallId = new AtomicLong(1L);

        @Override
        public EventListener create(Call call) {
            long callId = nextCallId.getAndIncrement();
            return new HttpEventListener(callId, call.request().url(), System.nanoTime());
        }
    };

    /**
     * 每次请求的标识
     */
    private final long callId;

    /**
     * 每次请求的开始时间，单位纳秒
     */
    private final long callStartNanos;

    private StringBuilder sbLog;

    public HttpEventListener(long callId, HttpUrl url, long callStartNanos) {
        this.callId = callId;
        this.callStartNanos = callStartNanos;
        this.sbLog = new StringBuilder(url.toString()).append(" ").append(callId).append(":");
    }

    private void recordEventLog(String name) {
        long elapseNanos = System.nanoTime() - callStartNanos;
        sbLog.append(String.format(Locale.CHINA, "%.3f-%s", elapseNanos / 1000000000d, name)).append(";");
        if (name.equalsIgnoreCase("callEnd") || name.equalsIgnoreCase("callFailed")) {
            //打印出每个步骤的时间点
            NearLogger.i(sbLog.toString());
        }
    }

    @Override
    public void callStart(Call call) {
        super.callStart(call);
        recordEventLog("callStart");
    }

    @Override
    public void dnsStart(Call call, String domainName) {
        super.dnsStart(call, domainName);
        recordEventLog("dnsStart");
    }

    @Override
    public void dnsEnd(Call call, String domainName, List<InetAddress> inetAddressList) {
        super.dnsEnd(call, domainName, inetAddressList);
        recordEventLog("dnsEnd");
    }

    @Override
    public void connectStart(Call call, InetSocketAddress inetSocketAddress, Proxy proxy) {
        super.connectStart(call, inetSocketAddress, proxy);
        recordEventLog("connectStart");
    }

    @Override
    public void secureConnectStart(Call call) {
        super.secureConnectStart(call);
        recordEventLog("secureConnectStart");
    }

    @Override
    public void secureConnectEnd(Call call, @Nullable Handshake handshake) {
        super.secureConnectEnd(call, handshake);
        recordEventLog("secureConnectEnd");
    }

    @Override
    public void connectEnd(Call call, InetSocketAddress inetSocketAddress, Proxy proxy, @Nullable Protocol protocol) {
        super.connectEnd(call, inetSocketAddress, proxy, protocol);
        recordEventLog("connectEnd");
    }

    @Override
    public void connectFailed(Call call, InetSocketAddress inetSocketAddress, Proxy proxy, @Nullable Protocol protocol, IOException ioe) {
        super.connectFailed(call, inetSocketAddress, proxy, protocol, ioe);
        recordEventLog("connectFailed");
    }

    @Override
    public void connectionAcquired(Call call, Connection connection) {
        super.connectionAcquired(call, connection);
        recordEventLog("connectionAcquired");
    }

    @Override
    public void connectionReleased(Call call, Connection connection) {
        super.connectionReleased(call, connection);
        recordEventLog("connectionReleased");
    }

    @Override
    public void requestHeadersStart(Call call) {
        super.requestHeadersStart(call);
        recordEventLog("requestHeadersStart");
    }

    @Override
    public void requestHeadersEnd(Call call, Request request) {
