使用Coldfusion

我需要在HTML中输出JSON结果，以便我可以在Coldfusion中使用它。我正在获取数据，但我不知道如何解析返回的数据，以便我可以使用它。我是个新人，所以对我很轻松。我根本不认识JSON，这是我第一次尝试工作。

    <cfset qpxFields = {
      "request": {
        "passengers": {
          "adultCount": "1"
        },
        "slice": [
          {
            "origin": "JNB",
            "destination": "MRU",
            "date": "2016-12-19"
          }
        ],
        "solutions": "1"
      }
    }/>

    <cfhttp url="https://www.googleapis.com/qpxExpress/v1/trips/search?key=AIzaSyB0NN9WYmrkc2Ikq9TVGzzAD_gGoSBSbP4" method="post" result="httpResp" timeout="60">
        <cfhttpparam type="header" name="Content-Type" value="application/json" />
        <cfhttpparam type="body" value="#serializeJSON(qpxFields)#">
    </cfhttp>

    <cfset getResult = deserializeJSON(httpResp.filecontent)>
    <cfoutput>#httpResp.filecontent#</cfoutput>

输出filecontent时得到的结果如下：

我正在使用CF 10。

2 个答案:

答案 0 :(得分：3)

不要试图处理HTTP响应（httpResp.filecontent），而是查看反序列化的内容（getResult）。当ColdFusion从JSON数据创建结构时，您不能简单地输出该变量。

将这样的反序列化JSON转储出来：

<cfdump var="#getResult#">

查看该输出，您将看到ColdFusion如何为您解析所有信息。您将获得一些结构值和一些数组值。您将需要使用适当的方法（例如，循环数组）来提取每个单独的数据。

回复您的评论

在ColdFusion中循环已有详细记录。为了帮助您入门，您可以查看Adobe文档本身 - cfloop。该页面上的文档显示了如何链接数组，结构等。

另一个好的参考是Learn CF In a Week - looping。

答案 1 :(得分：0)

当您必须遍历一维或二维结构或数组时，循环工作。当数据在3个或更多维度中组合结构和数组时，如在该特定问题中那样，则循环通常不足以作为解决方案。复杂性肯定会压倒大多数初学者。

一个好的解决方案就是愚蠢。从结果开始，结构为getResult。如先前其他人所建议的那样进行转储。然后只需通过眼睛和深入查看值。
