socket.io-redis在redis 3.0.6中获取尾部字节错误

Question

我使用phpredis通过pubsub方法向node.js发送数据。在将node.js升级到稳定版本4.2之后，我从socket.io-redis模块得到了trailing byte错误。

node.js

var pub = redis.createClient(2222, '127.0.0.1',{no_ready_check: true})

pub.auth(redisPassword);

var allsub = redis.createClient(2222, '127.0.0.1',{return_buffers: true,no_ready_check: true})

allsub.auth(redisPassword);

allsub.subscribe('somekey');

io.adapter(RedisStore({pubClient:pub,subClient:allsub}));

错误：

   Error: 256 trailing bytes

为了找出问题所在，我已经将socket.io降级到1.36，但是错误仍然存在。

我遵循了this thread中建议的解决方案，但它们不起作用。

1.添加return_buffers:实例为true不起作用。

重新启动时将导致以下警告：

[nodemon] restarting due to changes...
[nodemon] starting `node node.js`
listening on *:3000
[TypeError: input.split is not a function]

2.更改上一篇文章中建议的msgpack-js-v5的依赖项，但这不起作用，如下所示：

socket.io-redis/index.js

var msgpack = require('msgpack-js-v5');

socket.io-redis/package.json：

 "dependencies": {
 "async": "0.9.0",
 "debug": "2.2.0",
 "msgpack-js-v5": "*",
 "redis": "2.4.2",
 "socket.io-adapter": "github:automattic/socket.io-adapter#de5cba",
 "uid2": "0.0.3"
 },

真是莫名其妙。有人能告诉我怎么修吗？

Answer 1

希望你redis是：

var redis = require('redis');

RedisStore是：

var RedisStore= require(socket.io-redis);

还可以将主机端口添加到io.adapter中的RedisStore中，如下所示：

io.adapter(RedisStore({ pubClient: pub, subClient: allsub, host: '127.0.0.1', port: 222 }));

对我来说很管用。如果你有什么问题，请告诉我。
