我正在尝试基于aleph
构建RCP服务器。它通过了所有测试,但当发送或接收的字节数组变大时,字节似乎已损坏。
例如。我试图发送一个长度为2936的字节数组,但服务器上只有1024个字节。
我遵循这个例子,并为nippy
做了自己的修改。编码和解码将由处理程序自己完成。
(defn wrap-duplex-stream
[s]
(let [out (s/stream)]
(s/connect out s)
(s/splice out s)))
(defn client
[host port]
(d/chain (tcp/client {:host host, :port port})
#(wrap-duplex-stream %)))
(defn start-server
[handler port]
(tcp/start-server
(fn [s info]
(handler (wrap-duplex-stream s) info))
{:port port}))
最佳答案
我最终为字节数组制作了自己的编解码器。
这很简单,但是要想知道如何用它来保持光泽和光泽是很费时的。
(defn buffer->byte-array [buf-seq]
(byte-streams/to-byte-array buf-seq))
(defn bytes-codec []
(reify
Reader
(read-bytes [this buf-seq]
(let [buf-seq (dup-bytes buf-seq)
byte-arr (buffer->byte-array buf-seq)]
[true byte-arr nil]))
Writer
(sizeof [x]
nil)
(write-bytes [x y byte-arr]
[(ByteBuffer/wrap byte-arr)])))
(def protocol
(gloss/compile-frame
(gloss/finite-frame
:uint32
(bytes-codec))
#(nippy/freeze %)
#(nippy/thaw %)))
(defn wrap-duplex-stream
[s]
(let [out (s/stream)]
(s/connect
(s/map #(io/encode protocol %) out)
s)
(s/splice
out
(io/decode-stream s protocol))))
(defn client
[host port]
(d/chain (tcp/client {:host host, :port port})
#(wrap-duplex-stream %)))
(defn start-server
[handler port]
(tcp/start-server
(fn [s info]
(handler (wrap-duplex-stream s) info))
{:port port}))
