将ParseLiveQueryServer作为独立运行

Question

我正在使用PM2运行parse-server 2.3.8，我正在尝试使用PM2运行具有相同解析实例的LiveQueryServer。下面是我的ecosystem.json中env的片段，它不起作用。

"env": {
    ...,
    "PARSE_SERVER_LIVE_QUERY_OPTIONS": {
        "classNames": ["MyClass", "MyOtherClass"],
        "appId": "myAppId",
        "masterKey": "myMasterKey",
        "serverURL": "https:://mydomain.com/parse"
    },
}

接下来，我创建了一个index.js并尝试将LiveQueryServer作为独立运行，但也无效。这是index.js的内容：

var express = require('express');
var ParseServer = require('parse-server').ParseServer;

var app = express();

var mount = 'parse';
var port = 1337;

var httpServer = require('http').createServer(app);
httpServer.listen(port);
ParseServer.createLiveQueryServer(httpServer, {
    'appId': 'myAppID',
    'serverURL': 'http:localhost:' + port + '/' + mount,
    'logLevel': 'VERBOSE'
});

这是我根据Parse文档中链接的nginx tutorial配置nginx以允许websockets所添加的内容。

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

upstream websocket {
    server localhost:1337;
}

server {
    listen 443;

    location /parse {
        proxy_pass http://websocket;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }
}
