標題[問題] java 1.6 vs 1.8 ssl socket連線問題
時間Thu Mar 26 11:34:25 2015
各位好，我想請教一個java 1.6 vs 1.8的問題
我目前有一支程式要跟主機用SSL溝通，丟一些資料
底下是我連線，收送的部分
我在jre1.6環境下跑
不用disconnect，只要socket建通，直接write and read
不管送收幾次都可以
但是只要環境切到1.8下,第一次執行收送是成功的，
但只要在馬上執行一次同樣動作
主機那邊似乎就收到他們解碼不出來的東西，所以沒有回應我
我client就會timeout
我疑惑的是
"socket建立起來，第一次收送，成功正常，但socket沒有斷，只是再第二次送資料，結
果就是主機收到解不出來的東西"
不知道有沒有人可以給我一點方向去查問題呢
感謝回答

1F：推 reon: 我沒用過1.8 但是Server端在收封包的時候 最好指定array大小 04/24 23:44
