public class OkHttpClientProvider implements IOkHttpClientProvider {

服务器上的保持活动持续时间为180秒，OkHttp的默认值为300秒

服务器在其头中返回“Connection：Close”，但客户端请求发送“Connection：KeepAlive”

服务器支持TLS 1.0/1.1/1.2，并使用开放式SSL

更新-通过okhttp添加全堆栈跟踪

Answer 1

最近，我在处理一些遗留代码时遇到了这个问题。在谷歌搜索后，我发现这个问题无处不在，但没有任何具体的解决方案。我处理了异常消息的各个部分，并在下面进行了分析。

分析：

1. SSLException:SSL（安全套接字层）发生异常，该层在JDK的javax.net.SSL包(openjdk/oraclejdk/androidsdk)
中实现
2. 读取错误ssl=#I/O错误在系统调用期间:从安全套接字读取时发生错误。它是在使用本机系统库/驱动程序时发生的。请注意，所有的平台solaris、Windows等都有自己的套接字库，由SSL使用。Windows使用WINSOCK库。
3. 由对等方重置连接:系统库报告此消息（Solaris reportseconnreset，Windows reportswsaeconnreset)称，由于远程主机强制关闭现有连接，数据传输中使用的套接字不再可用。需要在主机和客户端之间创建一个新的安全路径

null

null

null

因此，上述参数中没有一个有助于保持网络的活力，从而使其失效。

我发现了一个可能有助于解决这个问题的设置，这就是函数

setKeepAlive(true)
setSoKeepalive(HttpParams params, enableKeepalive="true") 

我是如何解决我的问题的？

null
