OkHttp3中设置超时的方法

见网址:http://square.github.io/okhttp/3.x/okhttp/

Method Detail

connectTimeout

public OkHttpClient.Builder connectTimeout(long timeout,
TimeUnit unit)

Sets the default connect timeout for new connections. A value of 0 means no timeout, otherwise values must be between 1 and Integer.MAX_VALUE when converted to milliseconds.

readTimeout

public OkHttpClient.Builder readTimeout(long timeout,
TimeUnit unit)

Sets the default read timeout for new connections. A value of 0 means no timeout, otherwise values must be between 1 and Integer.MAX_VALUE when converted to milliseconds.

writeTimeout

public OkHttpClient.Builder writeTimeout(long timeout,
TimeUnit unit)

Sets the default write timeout for new connections. A value of 0 means no timeout, otherwise values must be between 1 and Integer.MAX_VALUE when converted to milliseconds.

从上面可以看到设置超时移到了OkHttpClient.Builder中，所以最新的设置超时的代码如下：

   public WebApi(){
        client = new OkHttpClient.Builder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .readTimeout(20, TimeUnit.SECONDS)
                .build();
    }

捕获OkHttp3超时

然后捕获异常，加以处理。

     this.serversListEvent = serversListEvent;
     serversLoadTimes = 0;
     Request request = new Request.Builder()
             .url(serversListUrl)
             .build();
     client.newCall(request).enqueue(new Callback() {

         @Override
         public void onFailure(Call call, IOException e) {
             if(e.getCause().equals(SocketTimeoutException.class) && serversLoadTimes<maxLoadTimes)//如果超时并未超过指定次数，则重新连接
             {
                 serversLoadTimes++;
                 client.newCall(call.request()).enqueue(this);
             }else {
                 e.printStackTrace();
                 WebApi.this.serversListEvent.getServers(null);
             }
         }

         @Override
         public void onResponse(Call call, Response response) throws IOException {
             String html = new String(response.body().bytes(), "big5");
             Matcher m = serversListPattern.matcher(html);
             ServersList serverList = new ServersList();
             while (m.find()){
                 serverList.add(new ServerInfo(m.group(1), m.group(2)));
             }

             Matcher mc1 = selectServerCodePattern.matcher(html);
             Matcher mc2 = selectCityCodePattern.matcher(html);
             if(mc1.find())
                 serverList.selectServerCode=mc1.group(1);
             if(mc2.find())
                 serverList.selectCityCode=mc2.group(1);

             WebApi.this.serversListEvent.getServers(serverList);
         }
     });
 }
