linux - 如何使用 grep 或 awk 查找字符串及其值

Question

这个问题已经有答案了:

Extract a specific field from JSON output using jq (3 个回答)

已关闭 4 年前。

我是 shell 脚本新手，并且刚刚开始接触它。

我最近编写了 shell 脚本来调用 REST API，并且能够毫无问题地执行它。

我已将输出存储在如下变量中

{
  "id": 3184136,
  "name": "XXX TEST API",
  "url": "http://xxxxxxxxxxx/_apis/test/Runs/3184136",

}

从上面的输出中，我试图找到“状态”及其值。但我没能做到这一点。请任何人帮助我。

echo $result | grep -o 'state*'

使用上面的命令，我能够打印状态。但我期待状态及其值。

感谢您的帮助。提前致谢。

我尝试将您的 json 存储在名为 n2.json 的文件中。

cat n2.json
{  
   "id":3184136,
   "name":"XXX TEST API",
   "url":"http://xxxxxxxxxxx/_apis/test/Runs/3184136",
   "isAutomated":true,
   "owner":{  
      "displayName":"XXXX",
      "url":"http://xxxxxxxxxxx/_apis/Identities/dbf722a9-73b0-46d6-a2bd-9835c1f0c221",
      "_links":{  
         "avatar":{  
            "href":"http://xxxxxxxxxxx/_api/_common/identityImage?id=dbf722a9-73b0-46d6-a2bd-9835c1f0c221"
         }
      },
      "id":"dbf722a9-73b0-46d6-a2bd-9835c1f0c221",
      "uniqueName":"xxxxxxxxxxx\\ServiceLaunchpadDev",
      "imageUrl":"http://xxxxxxxxxxx/_api/_common/identityImage?id=dbf722a9-73b0-46d6-a2bd-9835c1f0c221"
   },
   "project":{  
      "id":"6d5e21e7-c75e-464a-9708-90fbff086902",
      "name":"eDellPrograms"
   },
   "startedDate":"2018-10-11T06:36:50.627Z",
   "completedDate":"2018-10-11T07:04:45.153Z",
   "state":"Completed",
   "plan":{  
      "id":"5299555",
      "name":"Smoke Dashboard Peso - DIT",
      "url":"http://xxxxxxxxxxx/_apis/test/Plans/5299555"
   },
   "postProcessState":"Complete",
   "totalTests":5,
   "incompleteTests":0,
   "notApplicableTests":0,
   "passedTests":0,
   "unanalyzedTests":5,
   "createdDate":"2018-10-11T06:36:50.533Z",
   "lastUpdatedDate":"2018-10-11T07:04:45.153Z",
   "lastUpdatedBy":{  
      "displayName":"xxxxxxxxxxx",
      "url":"http://xxxxxxxxxxx/_apis/Identities/8de2a654-063b-48bd-8101-87e4ec2f05e3",
      "_links":{  
         "avatar":{  
            "href":"http://xxxxxxxxxxx/_api/_common/identityImage?id=8de2a654-063b-48bd-8101-87e4ec2f05e3"
         }
      },
      "id":"8de2a654-063b-48bd-8101-87e4ec2f05e3",
      "uniqueName":"xxxxxxxxxxx\\xxxxxxxxxxx",
      "imageUrl":"http://xxxxxxxxxxx/_api/_common/identityImage?id=8de2a654-063b-48bd-8101-87e4ec2f05e3"
   },
   "controller":"xxxxxxxxxxx",
   "revision":5,
   "comment":"Build Definition : xxxxxxxxxxx \nBuild Version : xxxxxxxxxxx_20180925.1\nConfiguration : DIT\nBatch type : Suite\nTest type : Parallel\nTest Controller Name : xxxxxxxxxxx\nPreferred Agents : ADPTAW10A618|ADPTAW10A619|ADPTAW10A621 \nRequested by : xxxxxxxxxxx\nEmail Request : Y\nEmail To : xxxxxxxxxxx\nEmailCc : xxxxxxxxxxx\nEnvironment : DIT\nTest Setting : DIT\nContinue On Failure : false\nDNS Setting : false",
   "dropLocation":"\\\\xxxxxxxxxxx\\DropFolder\\xxxxxxxxxxx_20180925.1",
   "runStatistics":[  
      {  
         "state":"Completed",
         "outcome":"Failed",
         "count":5
      }
   ],
   "webAccessUrl":"http://xxxxxxxxxxx/_TestManagement/Runs#runId=3184136&_a=runCharts"
}

然后在此之上使用jq:

jq -r '.state' n2.json 
Completed
