将android客户端连接到sails.js

我正在使用。 如何将其连接到sails.js服务器？ 我尝试了和的方法，但在我的sails服务器上出现以下错误：

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.

在已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此问题。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，则可以研究另一个领域

如果客户端id低于

0.11.0

，套接字io将面临解析虚拟请求的问题。解决方法是编辑

解析sdk元数据.js

文件，该文件可以在

/node\u modules/sails hook sockets/lib/

或

/node\u modules/sails/node\u modules/sails hook sockets/lib/

中找到，具体取决于您的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';
}

至：

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

错误（SAILS:HOOK:SOCKETS:PARSE\u VIRTUAL\u REQ）

如何创建套接字实例？url看起来怎么样？我不创建或打开任何套接字。通过搜索，我发现sails有一个功能，在常规路线上它支持

socket.io

连接。我遇到了同样的错误，你是否修复了这个错误？@jaumard这可能是由于sails中的一个错误，当时我试图在services.js中打开一个web套接字并手动与客户端对话，从长远来看，sails.js的预算低，开发速度慢，所以我现在使用meteor.js。

if (!(handshake.headers[SDK_META_PARAMS.version] || handshake.query[SDK_META_PARAMS.version])) {
            handshake.query[SDK_META_PARAMS.version] = '0.11.0';
}
