如何创建一个JSON对象来显示两个不同的JSON文件中每个键的值的差异？
这将是一个很长的帖子，但主要是由于我使用的JSON文件。请原谅我。
我有一个源文件-original. json

{
  "billLogAnalyticsAsDavisDataUnits": false,
  "billingProvider": "INTERNAL",
  "blockUIDate": 1652572799000,
  "chatEnabled": false,
  "customMetricsLimit": 9223372036854776000,
  "customMetricsOverageLimit": 9223372036854776000,
  "davisDataUnitsAnnualLimit": -1,
  "davisDataUnitsEnabled": false,
  "davisDataUnitsMigrated": false,
  "davisDataUnitsMonthlyLimit": -1,
  "demUnitsAnnualQuota": 0,
  "demUnitsQuota": 0,
  "expirationCounterEnabled": true,
  "expirationTime": 1652572799000,
  "externalApiQuota": 2147483647,
  "hostUnitsCapping": {
    "fullstackHostLimit": 0,
    "hasContainersHostLimit": 0,
    "hostUnitsCappingEnabled": false,
    "infrastructureOnlyHostLimit": 0
  },
  "hostUnitsQuota": 2147483647,
  "ibmSystemZCICSIMSMonitoring": false,
  "infrastructureSupportedTechnologies": {
    "infrastructureOnlySupport": true,
    "logAgent": true,
    "maxInfrastructureOnlyAgents": 9223372036854776000,
    "networkAgent": true,
    "pluginAgent": true
  },
  "iotEntityQuota": 20,
  "iotTsQuota": 10,
  "isConsumption": false,
  "isCreditExhausted": false,
  "isRumEnabled": false,
  "licenseType": "PAYING",
  "logAnalyticsIngressQuota": 9223372036854776000,
  "logAnalyticsIngressQuotaAnnually": 9223372036854776000,
  "logAnalyticsStorageEnabled": false,
  "logAnalyticsStorageQuota": 0,
  "maxActionsPerMinute": 3500,
  "maxAgents": 2147483647,
  "maxHostUnitsQuota": -1,
  "maxPaasAgents": 2147483647,
  "maxWebChecks": 9223372036854776000,

  "overageCustomMetrics": true,
  "overageEnabled": false,
  "replayStorageDomQuotaInMb": 10000,
  "replayStorageDomRetention": 86400000,
  "retentionCode": 864000000,
  "retentionRum": 864000000,
  "retentionService": 1209600000,
  "retentionWebcheck": 864000000,
  "rumAdditionalUserPropertiesEnabled": true,
  "rumAdditionalUserPropertiesLowerLimit": 20,
  "sessionReplayEnabled": false,
  "sessionStorageQuota": 2147483647,
  "suspensionType": "NONE",
  "symbolicationFileStorageQuota": 1024,
  "syntheticEnabled": false,
  "useHostUnitWeighting": false,
  "visitsAnnualQuota": -1,
  "visitsQuota": -1
}

我需要替换存储在template.json文件中的具有新值的一些键

{
    "billLogAnalyticsAsDavisDataUnits": false,
    "billingProvider": "INTERNAL",
    "blockUIDate": 1652572799000,
    "chatEnabled": false,
    "demUnitsAnnualQuota": -1,
    "demUnitsQuota": -1,
    "isRumEnabled": false,
    "licenseType": "PAYING",
    "logAnalyticsIngressQuota": -1,
    "logAnalyticsIngressQuotaAnnually": -1,
    "logAnalyticsStorageEnabled": false,
    "logAnalyticsStorageQuota": 0,
    "overageCustomMetrics": true,
    "overageEnabled": false,
    "replayStorageDomQuotaInMb": 10000,
    "replayStorageDomRetention": 86400000,
    "retentionCode": 864000000,
    "retentionRum": 864000000,
    "retentionService": 1209600000,
    "retentionWebcheck": 864000000,
    "rumAdditionalUserPropertiesEnabled": true,
    "rumAdditionalUserPropertiesLowerLimit": 20,
    "sessionReplayEnabled": false,
    "sessionStorageQuota": 102400,
    "suspensionType": "NONE",
    "symbolicationFileStorageQuota": 1024,
    "syntheticEnabled": true,
    "useHostUnitWeighting": false,
    "visitsAnnualQuota": 0,
    "visitsQuota": -1
}

我正在用jq的下面的电话

jq -n --argfile original.json --argfile template template.json '$original |$original +=$template' >updated.json

获取新的updated. json文件，并将其提交给API服务器。
API服务器处理后发出一个结构完全相同的新文件。但是，某些键值可能会更改。下面是从API服务器下载的文件-downloaded. json

{
  "billLogAnalyticsAsDavisDataUnits": false,
  "billingProvider": "INTERNAL",
  "blockUIDate": 1652572799000,
  "chatEnabled": false,
  "customMetricsLimit": 9223372036854776000,
  "customMetricsOverageLimit": 9223372036854776000,
  "davisDataUnitsAnnualLimit": -1,
  "davisDataUnitsEnabled": true,
  "davisDataUnitsMigrated": false,
  "davisDataUnitsMonthlyLimit": -1,
  "demUnitsAnnualQuota": -1,
  "demUnitsQuota": -1,
  "expirationCounterEnabled": true,
  "expirationTime": 0,
  "externalApiQuota": 2147483647,
  "hostUnitsCapping": {
    "fullstackHostLimit": 0,
    "hasContainersHostLimit": 0,
    "hostUnitsCappingEnabled": false,
    "infrastructureOnlyHostLimit": 0
  },
  "hostUnitsQuota": -1,
  "ibmSystemZCICSIMSMonitoring": false,
  "infrastructureSupportedTechnologies": {
    "infrastructureOnlySupport": true,
    "logAgent": true,
    "maxInfrastructureOnlyAgents": 9223372036854776000,
    "networkAgent": true,
    "pluginAgent": true
  },
  "iotEntityQuota": 20,
  "iotTsQuota": 10,
  "isConsumption": false,
  "isCreditExhausted": false,
  "isRumEnabled": true,
  "licenseType": "PAYING",
  "logAnalyticsIngressQuota": -1,
  "logAnalyticsIngressQuotaAnnually": -1,
  "logAnalyticsStorageEnabled": false,
  "logAnalyticsStorageQuota": 0,
  "maxActionsPerMinute": 3500,
  "maxAgents": 2147483647,
  "maxHostUnitsQuota": -1,
  "maxPaasAgents": 2147483647,
  "maxWebChecks": 9223372036854776000,
  "maxWebChecksAnnual": 9223372036854776000,
  "overageCustomMetrics": true,
  "overageEnabled": false,
  "replayStorageDomQuotaInMb": 10000,
  "replayStorageDomRetention": 86400000,
  "retentionCode": 864000000,
  "retentionRum": 864000000,
  "retentionService": 1209600000,
  "retentionWebcheck": 864000000,
  "rumAdditionalUserPropertiesEnabled": true,
  "rumAdditionalUserPropertiesLowerLimit": 20,
  "sessionReplayEnabled": false,
  "sessionStorageQuota": 102400,
  "suspensionType": "NONE",
  "symbolicationFileStorageQuota": 1024,
  "syntheticEnabled": true,
  "useHostUnitWeighting": false,
  "visitsAnnualQuota": 0,
  "visitsQuota": -1
}

下面是我的任务-我需要找到updated. json和downloaded. json之间的差异
我正在使用diff

diff <(jq -S . update.json) <(jq -S . downloaded.json)

它产生以下结果

<   "davisDataUnitsEnabled": false,
---
>   "davisDataUnitsEnabled": true,
15c15
<   "expirationTime": 1652572799000,
---
>   "expirationTime": 0,
23c23
<   "hostUnitsQuota": 2147483647,
---
>   "hostUnitsQuota": -1,
36c36
<   "isRumEnabled": false,
---
>   "isRumEnabled": true,

我想要的是-用原始文件（来自updated.json）和新文件（来自downloaded.json）创建一个新对象，所以它应该看起来像下面这样：

"Original": {
        "davisDataUnitsEnabled": false,
        "expirationTime": 1652572799000,
        "hostUnitsQuota": 2147483647,
        "isRumEnabled": false
    },
    "Updated": {
        "davisDataUnitsEnabled": true,
        "expirationTime": 0,
        "hostUnitsQuota": -1,
        "isRumEnabled": true
    }
}

我试着用to_entries和from_entries看看更新和下载的区别，用下面的jq命令把所有结合在一起：

jq -n \
--argfile original original.json \
--argfile download downloaded.json \
--argfile template template.json \
'$original |$original +=$template | 
($original | to_entries) as $x | 
($download | to_entries) as $y | 
$y - $x | from_entries'

但是，与diff相比，输出有很大不同：

{
  "davisDataUnitsEnabled": true,
  "demUnitsAnnualQuota": -1,
  "demUnitsQuota": -1,
  "expirationTime": 0,
  "hostUnitsQuota": -1,
  "isRumEnabled": true,
  "logAnalyticsIngressQuota": -1,
  "logAnalyticsIngressQuotaAnnually": -1,
  "sessionStorageQuota": 102400,
  "syntheticEnabled": true,
  "visitsAnnualQuota": 0
}

上面的输出中还列出了七个键，而不是diff中的四个，这七个键在updated.json和downloaded.json中的值完全相同
我的问题是什么原因导致这七个额外的键出现在jq输出中？我可以用jq得到值不同的键的正确输出，并按照我想要的方式格式化输出吗？

  • -P.S.经过一番挖掘，发现comm给了我想要的输出
comm --nocheck-order -13 <(jq -S . updated.json) <(jq -S . downloaded.json)

它产生输出：

"davisDataUnitsEnabled": true,
  "expirationTime": 0,
  "hostUnitsQuota": -1,
  "isRumEnabled": true,

现在，如果我可以通过JQ将输出放在"Updated"对象下，同时忽略后面的逗号，这可能就是最终结果了。

在发布问题并重新检查下面的jq命令之后，我发布了一个声明，我没有将原始文件和模板文件合并在一个变量中，所以原始的、未经修改的文件被分配给var $x。

jq -n \
--argfile original original.json \
--argfile download downloaded.json \
--argfile template template.json \
'$original |$original +=$template | 
($original | to_entries) as $x | 
($download | to_entries) as $y | 
$y - $x | from_entries

相反，产生我想要的结果的正确jq命令如下：

jq -n \
--argfile original original.json \
--argfile download downloaded.json \
--argfile template template.json \
'$original |($original +=$template | to_entries) as $x |
($download | to_entries) as $y | 
($y - $x | from_entries) as $new |
($x - $y | from_entries) as $old |
[{"Original":$old,"Updated": $new}]'

它产生正确的输出：

[
  {
    "Original": {
      "davisDataUnitsEnabled": false,
      "expirationTime": 1652572799000,
      "hostUnitsQuota": 2147483647,
      "isRumEnabled": false
    },
    "Updated": {
      "davisDataUnitsEnabled": true,
      "expirationTime": 0,
      "hostUnitsQuota": -1,
      "isRumEnabled": true
    }
  }
