mongodb - 如何使用带 Loopback 的 SSL 连接到 MongoDB 数据库

Question

我正在尝试使用环回连接到 Rackspace 中带有 SSL 的 MongoDB 数据库，但它不起作用。似乎连接正常；如果我(故意)输入错误的凭据，我会收到一条错误消息，提示“无法连接”，但是当我使用正确的凭据时，不会显示任何错误，所以我认为我连接正常。但是当我尝试查询数据库时它总是超时，知道发生了什么事吗？

我的 datasources.json 看起来像这样:

"db": {
   "name": "mongodb",
   "url": "mongodb://username:password@iad-mongos2.objectrocket.com:port/dbName?ssl=true",
   "debug": true,
   "connector": "mongodb"
  }

我一直在阅读有关需要证书文件的内容，但不确定这是否适用于这种情况。

如有任何帮助，我们将不胜感激!

如下使用 datasources.env.js

var cfenv = require('cfenv');
var appenv = cfenv.getAppEnv();

// Within the application environment (appenv) there's a services object
var services = appenv.services;

// The services object is a map named by service so we extract the one for MongoDB
var mongodb_services = services["compose-for-mongodb"];

var credentials = mongodb_services[0].credentials;

// Within the credentials, an entry ca_certificate_base64 contains the SSL pinning key
// We convert that from a string into a Buffer entry in an array which we use when
// connecting.
var ca = [new Buffer(credentials.ca_certificate_base64, 'base64')];

var datasource = {
    name: "db",
    connector: "mongodb",
    url:credentials.uri,
    ssl: true,
    sslValidate: false,
    sslCA: ca
};
module.exports = {
    'db': datasource
};
