如何解析在ColdFusion中返回的JSON [英] How to Parse JSON Returned in ColdFusion

问题描述

我相信这是一个相对简单的问题，但我不能在任何地方找到一个简单的答案。

I'm sure this is a relatively simple question, but I can't seem to find a simple answer anywhere online.

我有几行JSON由cfhttp POST返回，其中包含我想要解析并显示在ColdFusion页面中的图片网址：

I have a few lines of JSON returned by a cfhttp POST with an image URL that I'd like to parse out and display in my ColdFusion page:

{
    "href": "http://server.arcgisonline.com/arcgis/rest/directories/arcgisoutput/ESRI_StreetMap_World_2D_MapServer/_ags_map734a6ad322dd493e84499d78f027d841.png",
    "width": 854,
    "height": 493,
    "extent": {
        "xmin": -8285407.015562119,
        "ymin": 4944008.4197687358,
        "xmax": -8220129.7934066672,
        "ymax": 4981691.8747132765,
        "spatialReference": {
            "wkid": 102100,
            "latestWkid": 3857
        }
    },
    "scale": 288895.27714399656
}

如何使href的值成为变量，和/或可能有一个按钮链接到下载它？

How can I make "href"'s value a part of a variable in ColdFusion, and/or potentially have a button linked to downloading it?

编辑：我忘了提到我使用ColdFusion MX - 也称为版本6 - 因此为什么我无法使用反序列化

I forgot to mention that I'm using ColdFusion MX - also known as version 6 - and hence why I cannot use the DeserializeJSON listed on Adobe's page

推荐答案

转换JSON（JavaScript Object Notation）字符串数据
表示为CFML数据，例如CFML结构或数组。

Converts a JSON (JavaScript Object Notation) string data representation into CFML data, such as a CFML structure or array.
