问题定位:凡是系统中出现大量的CLOSE_WAIT,说明你的代码写的有问题,即:没有关闭连接。凡是系统中出现大量的TIME_WAIT,说明TCP连接主动关闭,一般是因为短连接导致的现象。在OkHttpClient中,默认时 HTTP头字段 Connection 设置值为keep-alive,这样会导致服务端断开连接时,客户端不能及时的断开连接,从而出现大量的CLOSE_...
instance.deduplicate(connectionPool, address, this); result = connection; } } closeQuietly(socket); return result; } 这里再简单的说下RealConnection的connect()因为这个方法也很重要。不过大家要注意RealConnection的connect()是StreamAllocation调用的。在RealConnection的connect()的方法里面也是一个while(true)的...

Actually, in all the cases I've seen so far, these errors (Connection reset as well as Unexpected end of stream) were only coming for those connection that were idle at the time when the server was shutting down and got reused for subsequent requests. The only connections that OkHttp remo...
OKHttp使用ConnectionPool来管理HTTP连接的复用和回收。在ConnectionPool的put方法中,会将连接放入连接池。在Connection的closeIfOwnedBy方法中,会关闭连接。 以上是OKHttp的核心源码片段,结合源码可以更加详细地了解其基本原理。实际的源码实现非常复杂,还涉及到线程管理、请求的解析和处理等众多细节。通过深入分析OKHttp的...
而在HTTP/1.1 中,真正引入了Keep-Alive机制,它默认是开启的,可以通过Connection:close进行关闭。在 HTTP 请求结束时,若启动了Keep-Alive机制,则该连接并不会立即关闭,此时如果有新的请求到来,且 host 相同,则会复用这条 TCP 连接进行请求,减少了 TCP 连接的频繁建立与关闭的资源消耗。
经查阅Connection-close解释 HTTP Connection的 close设置允许客户端或服务器中任何一方关闭底层的连接双方都会要求在处理请求后关闭它们的TCP连接。 看到这里之后决定同时在服务端的response中添加header ("Connection":"close") 在此之后暂未出现此异常
增加Connection=false后头部如下: 关于Http头 Connection=close的作用: 在http1.1中request和reponse header中都有可能出现一个connection头字段,此header的含义是当client和server通信时对于长链接如何进行处理。 在http1.1中,client和server都是默认对方支持长链接的, 如果client使用http1.1协议,但又不希望使用长链接,则需...
