ColdFusion CFHTTP使用从API返回的数据

Question

我刚刚开始使用Rotten Tomatoes API来检索电影信息，我需要一些帮助来了解如何处理返回的数据。这是我第一次使用这样的API，所以如果这听起来很基本，请原谅我。

使用cfhttp我可以成功连接到API并返回搜索数据，但我真的不知道我要回的格式。我以为它是JSON，但使用isJSON检查它返回false。我希望能够在返回的数据中调用各个字段来填充我可以输出给用户的查询结果集。

我用来拨打电话的代码很简单：

<cfhttp url="#apiURL#movies.json?apikey=#apiKey#&q=#movieName#" method="get" result="httpResp" timeout="120">
    <cfhttpparam type="header" name="Content-Type" value="application/json" />
</cfhttp>
<cfdump var="#httpResp#" />

正在返回的数据：

我不希望有人给我一个关于如何构建我的应用程序的完整演练，但如果有人可以给我一些关于将数据转换为查询结果的正确方法的指示，或者其他我可以使用，我很感激。

编辑：没有意识到图像难以阅读，所以这里是返回数据的剪切和粘贴。

编辑：谢谢，丹。那是我需要的轻推。在我了解了如何获取JSON数据后，我能够找到有关如何将其转换为有用查询的以下说明：Work with remote API JSON data in CF。

Answer 1

需要对数据进行反序列化：

<cfset tomatoData=DeserializeJSON(httpResp.filecontent)>

<cfdump var="#tomatoData#">

看起来第一级别只有结构。所以你可以

<cfdump var="#tomatoData.total#"> <!--- A single item --->
<cfdump var="#tomatoData.movies#"> <!--- An array --->

Answer 2

filecontent看起来像json。您可以使用

来引用它

#httpResp.filecontent#.
