MeteorJS：很难理解集合

Question

我是 MeteorJS 的新手，我正在构建一个应用程序，该应用程序基于 XML api 服务在 Google 地图上绘制点（使用他们的 API），当单击其中一个点时，将显示详细信息。非常直接。

我正在苦苦挣扎的是我需要存储 API 结果，以便每次加载页面时都不会 ping API，并且由于 Meteor 使用 MongoDB，我想将结果存储在一个集合中，但我是只是不确定我是否了解如何使用它们。

这是 XML 提要的样子：

<api version="1.0">
    <id>597837338</id>
    <time>3/6/2014 11:46:46 PM</time>
    <machine>query://djsearch6/dejobs</machine>
    <query>sales OR marketing</query>
    <recordcount>500</recordcount>
    <startrow>1</startrow>
    <endrow>10</endrow>
    <order>relevance</order>
    <jobs>
    <job>
        <title>
        Customer Service Representative - State Farm Agent Team Member (Property and Casualty Insurance Focus)
        </title>
        <url>http://my.jobs/a897284496c14249a8473d5947d08b4d321</url>
        <company>Cie Taylor - State Farm Agent</company>
        <location>Mesa, AZ</location>

        <jvid>a897284496c14249a8473d5947d08b4d321</jvid>
    </job>
    <job>
        <title>
        Insurance and Financial Services Position - State Farm Agent Team Member (Sales experience preferred)
        </title>
        <url>http://my.jobs/1b717b9492464fbabbd22d3c0e8cf08d321</url>

        <jvid>1b717b9492464fbabbd22d3c0e8cf08d321</jvid>
    </job>
  </jobs>
</api>

我认为这可以给你一个大致的想法，如果我没有以正确的方式理解你的问题，我很抱歉：

用于从 XML 解析为 JSON：http://davidwalsh.name/convert-xml-json

首先将 XML 解析为 JSON，例如想象一下从 XML 中提取的这个 JSON：

var dataFromXML = {
    "company": 597837338,
    "createdAt": "3/6/2014 11:46:46 PM",
    "jobs": [
        {"title": "job1", "url": "job1url", "company": "job1company", "location": "job1location", "dateUpdate": "job1date", "id": "job1id" },
        {"title": "job2", "url": "job2url", "company": "job2company", "location": "job2location", "dateUpdate": "job2date", "id": "job2id" }
    ]
};

现在在服务器脚本上，您可以在集合中插入此数据：

JobsCollection.insert({company: dataFromXML.company ,dataFromAPI: dataFromXML});

如果你的结果是一个数组，你可以在 forEach 循环中运行它：

var dataFromXMLArray = [
    {
        "company": 597837338,
        "createdAt": "3/6/2014 11:46:46 PM",
        "jobs": [
            {"title": "job1", "url": "job1url", "company": "job1company", "location":   "job1location", "dateUpdate": "job1date", "id": "job1id" },
            {"title": "job2", "url": "job2url", "company": "job2company", "location": "job2location", "dateUpdate": "job2date", "id": "job2id" }
        ]
    },
    {
        "company": 597837338,
        "createdAt": "3/6/2014 11:46:46 PM",
        "jobs": [
            {"title": "job1", "url": "job1url", "company": "job1company", "location": "job1location", "dateUpdate": "job1date", "id": "job1id" },
            {"title": "job2", "url": "job2url", "company": "job2company", "location": "job2location", "dateUpdate": "job2date", "id": "job2id" }
        ]
    }
];

dataFromXMLArray.forEach(function (data) {
    JobsCollection.insert({company: data.company, dataFromAPI: data});
});
