一次会话后，开始出现两次read ECONNRESET at exports._errnoException (util.js:870:11) at TCP.onread (net.js:544:26) 的异常信息，接着就报出Error: socket hang up at createHangUpError (_http_client.js:200:15) at Socket.socketOnEnd (_http_client.js:285:23) at emitNone (events.js:72:20) at Socket.emit (events.js:166:7) at endReadableNT (_stream_readable.js:905:12) at nextTickCallbackWith2Args (node.js:437:9) at process._tickCallback (node.js:351:17)， 这一般是我在会话中哪个地方没处理好呢？找了好半天，一直没头绪啊，没头绪。。。
