有没有办法在OkHTTP库上获取当前运行/等待请求的数量？

我发现了类似的内容，但它返回了请求的总数。

Log.d(TAG, String.format("Hit count=%d.", getOkHttpClient().getCache().getHitCount()));
Log.d(TAG, String.format("Network count=%d.", getOkHttpClient().getCache().getNetworkCount()));
Log.d(TAG, String.format("EoRequestSpec count=%d.", getOkHttpClient().getCache().getRequestCount()));

我有意使用拦截器，但想知道更好的方法。

修改

我添加了测试应用的日志输出。您可以看到有1个活动连接，但getConnectionCount()和getHttpConnectionCount()都返回0。

ConnectionPool类的Java文档说：

  

管理HTTP和SPDY连接的重用以减少网络   潜伏。共享相同{@link的HTTP请求   com.squareup.okhttp.Address}可以共享{@link   com.squareup.okhttp.Connection}。这个类实现了策略   哪些连接保持开放以供将来使用。

2 个答案:

答案 0 :(得分：3)

从版本3开始，可以使用queuedCallsCount和runningCallsCount

答案 1 :(得分：1)

您需要检查客户端实例中的ConnectionPool。

int connections = getOkHttpClient().getConnectionPool().getConnectionCount();
int httpConnections = getOkHttpClient().getConnectionPool().getHttpConnectionCount();
