我正在使用 nkzawa socket.io android client . 如何将它连接到 sails.js 服务器？ 我尝试了 Sending Socket request from Client (iOS & Android) to Sails.js Server 中的方法和 Simple Sails.js and Android Example但是我的 sails 服务器出现以下错误:

This will start this socket off with an empty session, i.e. (req.session === {})
That "anonymous" section will only last until the socket is disconnected unless you persist the session id in your database,
or by setting the set-cookie response header for an HTTP request that you *know* came from the same user (etc)
Alternatively, just make sure the socket sends a `cookie` header or query param when it initially connects.

这是我的安卓客户端:
JSONArray arr = new JSONArray();
JSONObject obj = new JSONObject();
try {
obj.put("url", "/user/new");
} catch (JSONException e) {
e.printStackTrace();
}
arr.put(obj);
socket.emit("get", arr);
最佳答案
在您构造为发送到服务器的对象中，跳过 JSONArray 包装器应该可以解决该问题。将代码更改为:
JSONObject obj = new JSONObject();
try {
obj.put("url", "/user/new");
} catch (JSONException e) {
e.printStackTrace();
}
socket.emit("get", obj);
如果问题仍然存在，则可以检查另一个区域。
如果客户端 ID 低于 0.11.0，Socket-io 将面临解析虚拟请求的问题。解决此问题的方法是编辑 parse-sdk-metadata.js 文件，该文件位于 /node_modules/sails-hook-sockets/lib/ 或 /node_modules/sails/node_modules/sails-hook-sockets/lib/ 取决于您的 NPM 版本。
在其中，更改以下内容:
if (!(handshake.headers[SDK_META_PARAMS.version] || handshake.query[SDK_META_PARAMS.version])) {
handshake.query[SDK_META_PARAMS.version] = '0.9.0';
}
收件人:
if (!(handshake.headers[SDK_META_PARAMS.version] || handshake.query[SDK_META_PARAMS.version])) {
handshake.query[SDK_META_PARAMS.version] = '0.11.0';
}
这应该可以解决您收到的 Error (SAILS:HOOK:SOCKETS:PARSE_VIRTUAL_REQ)!

最近因为项目需要，需要将Android手机系统自带的某个系统软件反编译并更改里面某个资源，并重新打包，签名生成新的自定义的apk，下面我来介绍一下我的实现过程。APK修改，分为以下几步：反编译解包,修改,重打包,修改签名等步骤。安卓apk修改准备工作1.系统配置好JavaJDK环境变量2.需要root权限的手机（针对系统自带apk,其他软件免root）3.Auto-Sign签名工具4.apktool工具安卓apk修改开始反编译本文拿Android系统里面的Settings.apk做demo,具体如何将apk获取出来在此就不过多介绍了，直接进入主题：按键win+R输入cmd，打开命令窗口，并将路

我有一个ruby脚本可以打开与Apple推送服务器的连接并发送所有待处理的通知。我看不出任何原因，但当Apple断开我的脚本时，我遇到了管道损坏错误。我已经编写了我的脚本来适应这种情况，但我宁愿只是找出它发生的原因，这样我就可以在第一时间避免它。它不会始终根据特定通知断开连接。它不会以特定的字节传输大小断开连接。一切似乎都是零星的。您可以在单个连接上发送的数据传输或有效负载计数是否有某些限制？看到人们的解决方案始终保持一个连接打开，我认为这不是问题所在。我看到连接在3次通知后断开，我看到它在14次通知后断开。我从未见过它能超过14点。有没有人遇到过这种类型的问题？如何处理？
我的意思是之前建立的那个DB=Sequel.sqlite('my_blog.db')或DB=Sequel.connect('postgres://user:password@localhost/my_db')或DB=Sequel.postgres('my_db',:user=>'user',:password=>'password',:host=>'localhost')等等。Sequel::Database类没有名为“disconnect”的公共(public)实例方法，尽管它有一个“connect”。也许有人已经遇到过这个问题。我将不胜感激。 最佳答案
