Question

我正在使用Spark编写一个使用Java的API（与我的问题无关，但它提供了一些上下文）。我有以下JSON（完全与我的后端返回）：

{"CfgCampaign":{"callingLists":{"CfgCallingListInfo":{"callingListDBID":{"value":126},"share":{"value":10},"isActive":{"value":2}}},"xmlns":"http://schemas.genesyslab.com/Protocols/Configuration/ConfServer/2005/","DBID":{"value":101},"name":{"value":"WI_Camp_1"},"state":{"value":1},"campaignGroups":{"CfgCampaignGroupInfo":[{"groupType":{"value":5},"dialerDBID":{"value":0},"optMethodValue":{"value":80},"origDNDBID":{"value":0},"numOfChannels":{"value":10},"groupDBID":{"value":826},"isActive":{"value":2},"scriptDBID":{"value":0},"trunkGroupDNDBID":{"value":0},"operationMode":{"value":1},"dialMode":{"value":2},"statServerDBID":{"value":176},"optRecBuffSize":{"value":6},"optMethod":{"value":1},"minRecBuffSize":{"value":4}},{"groupType":{"value":5},"dialerDBID":{"value":0},"optMethodValue":{"value":80},"origDNDBID":{"value":0},"numOfChannels":{"value":10},"groupDBID":{"value":827},"isActive":{"value":2},"scriptDBID":{"value":0},"trunkGroupDNDBID":{"value":0},"operationMode":{"value":1},"dialMode":{"value":2},"statServerDBID":{"value":176},"optRecBuffSize":{"value":6},"optMethod":{"value":1},"minRecBuffSize":{"value":4}}]},"scriptDBID":{"value":0},"tenantDBID":{"value":101}}}

根据https://jsonlint.com/似乎有效我将它作为JSONObject存储在我的代码中（基本上，上面是toString（）的结果）。但是，当我尝试在JSONArray中提取“campaignGroups”时，我得到：

org.json.JSONException: JSONObject["campaignGroups"] not found.

我实际上是因为尝试获取任何密钥而得到此错误，例如调用get（“DBID”）将返回相同的错误。

我对这里发生的事情感到有点困惑，任何帮助都会受到赞赏。

编辑：因为它只是从例外显而易见，我使用的是json.org

谢谢！

Answer 1

我相信您遇到的错误是由于外部JSON对象＆＃34; CfgCampaign＆＃34;，其中包含其余数据。有关如何使用org.json库解决此问题的示例代码如下所示：

// Loads the JSON (assuming you provide it as a string).
JSONObject x = new JSONObject(...);
// Gets and stores a reference to the outer object.
JSONObject y = x.getJSONObject("CfgCampaign");
// Now you can access any of the nested fields as follows.
JSONObject z = y.getJSONObject("campaignGroups");

在该对象上调用toString（）应该返回一个类似＆＃34; [Object Object]＆＃34;的字符串，如果必须在其上调用toString方法，那么您还需要在其上调用JSON.parse（your_object_here）来访问它上面的属性。

此外，您似乎需要寻找your_object_name.CfgCampaign.campaignGroups或your_object_name [＆＃34; CfgCampaign＆＃34;] [＆＃34; campaignGroups＆＃34;，但它已经找到了如果没有您用来访问广告系列组的代码，很难说清楚。

如果设置类似

的内容

const obj = {"CfgCampaign":{"callingLists":{"CfgCallingListInfo":{"callingListDBID":{"value":126},"share":{"value":10},"isActive":{"value":2}}},"xmlns":"http://schemas.genesyslab.com/Protocols/Configuration/ConfServer/2005/","DBID":{"value":101},"name":{"value":"WI_Camp_1"},"state":{"value":1},"campaignGroups":{"CfgCampaignGroupInfo":[{"groupType":{"value":5},"dialerDBID":{"value":0},"optMethodValue":{"value":80},"origDNDBID":{"value":0},"numOfChannels":{"value":10},"groupDBID":{"value":826},"isActive":{"value":2},"scriptDBID":{"value":0},"trunkGroupDNDBID":{"value":0},"operationMode":{"value":1},"dialMode":{"value":2},"statServerDBID":{"value":176},"optRecBuffSize":{"value":6},"optMethod":{"value":1},"minRecBuffSize":{"value":4}},{"groupType":{"value":5},"dialerDBID":{"value":0},"optMethodValue":{"value":80},"origDNDBID":{"value":0},"numOfChannels":{"value":10},"groupDBID":{"value":827},"isActive":{"value":2},"scriptDBID":{"value":0},"trunkGroupDNDBID":{"value":0},"operationMode":{"value":1},"dialMode":{"value":2},"statServerDBID":{"value":176},"optRecBuffSize":{"value":6},"optMethod":{"value":1},"minRecBuffSize":{"value":4}}]},"scriptDBID":{"value":0},"tenantDBID":{"value":101}}}

然后要在campaignGroups中获取数组，您需要看起来像：

obj.CfgCampaign.campaignGroups

试图从JSONObject中获取JSONArray失败
