问题是您的负载包含内部无效 JSON 负载。可以使用查询语言 "fix" 它（请参阅下面示例中 replace() 的用法），但是最好先编写有效的 JSON 有效负载.

尝试运行这个：

print s = @'{"pipelineId":"63dfc1f6-5a43-5bca-bffe-6a36a435e19d","vmId":"9252382a-814f-4d02-9b1b-305db4caa208/usl-exepipe-dev/westus/usl-exepipe-lab-dev/asuvp306563","artifactResult":{"Id":"execution-job-2","SourceName":"USL Repository","ArtifactName":"install-lcu","Status":"Succeeded","Parameters":null,"Log":"[{\"code\":\"ComponentStatus/StdOut/succeeded\",\"level\":\"Info\",\"displayStatus\":\"Provisioning succeeded\",\"message\":\"2020-06-02T14:33:04.711Z | I | Starting artifact ''install-lcu''\r\n2020-06-02T14:33:04.867Z | I | Starting Installation\r\n2020-06-02T14:33:04.899Z | I | C:\USL\LCU\4556803.msu Exists.\r\n2020-06-02T14:33:04.914Z | I | Starting installation process ''C:\USL\LCU\4556803.msu /quiet /norestart''\r\n2020-06-02T14:43:14.169Z | I | Process completed with exit code ''3010''\r\n2020-06-02T14:43:14.200Z | I | Need to restart computer after hotfix 4556803 installation\r\n2020-06-02T14:43:14.200Z | I | Finished Installation\r\n2020-06-02T14:43:14.200Z | I | Artifact ''install-lcu'' succeeded\r\n\",\"time\":null},{\"code\":\"ComponentStatus/StdErr/succeeded\",\"level\":\"Info\",\"displayStatus\":\"Provisioning succeeded\",\"message\":\"\",\"time\":null}]","DeploymentLog":null,"StartTime":"2020-06-02T14:32:40.9882134Z","ExecutionTime":"00:11:21.2468597","BSODCount":0},"attempt":1,"instanceId":"a301aaa0c2394e76832867bfeec04b5d:0","parentInstanceId":"78d0b036a5c548ecaafc5e47dcc76ee4:2","eventName":"Artifact Result"}'
| mv-expand log = parse_json(replace("\r\n", " ", replace(@"\", @"\\", tostring(parse_json(tostring(parse_json(s).artifactResult)).Log))))
