You can use the template from the Chrome Developer tool and a PowerShell script to create content.

To capture content for a post request with Chrome Developer tool

1. Using a Chrome browser, create content in AVEVA Historian Client Web.

2. Press F12 to open the Chrome Developer tool.

3. In the Chrome Developer tool:

   1. Select the Network tab.

   2. Click to clear the tool's displayed information.

4. In AVEVA Historian Client Web, save your content.

5. In the Developer tool:

   3. Click the "Content" line to see details.

   4. In the General section, note the Request URL:

      

   5. In the Request Payload section, copy all the content.

      

6. Paste the request payload into a JSON formatter and make any edits.

   • Remove these items: URL property, CreationDate, LastModifiedDate, LastAccessedDate, and SharedDate, the numeric portion of the UserID (retain the email address), and TenantID.

   • Optionally, modify these items as needed: FavoriteName, UserID (email address only), and UserName.

     Thjs is an example of the resulting code:

     {

     "upsert": {

     "LayoutInfo": {

     "DashboardContents": [

     ],

     "Layout": [

     {

     "Type": "Column Chart",

     "Name": "All Numeric",

     "IsActiveGroup": "true",

     "Tags": [

     ],

     "UIProperties": "{\"version\":{\"major\":1,\"minor\":5,\"timestamp\":\"\"},\"selectedOptions\":
     {\"limitLine\":{\"visible\":false,\"position\":10,\"text\":\"Limit Line Text\"},\"legend\":
     {\"visible\":true},\"xAxis\":{\"label\":\"DateTime\"},\"yAxis\":{\"label\":
     \"All Tags\"},\"dates\":{\"from\":
     \"2018-11-15T19:30:00.000Z\",\"to\":\"2018-11-15T20:04:33.099Z\"},\"aggregation\":
     \"Maximum\",\"isChartOptionAvailable\":true,\"isTimeAggregateAvailable\":
     true,\"isValueAggregateAvailable\":true,\"isCSVDownloadAllowed\":true,\"timeAggregate\":\"15MINUTES\"}}"

     },

     {

     "Type": "",

     "Name": "None",

     "IsActiveGroup": "false",

     "Tags": [

     ],

     "UIProperties": ""

     },

     {

     "Type": "",

     "Name": "65F",

     "IsActiveGroup": "false",

     "Tags": [

     ],

     "UIProperties": ""

     }

     ],

     "TagDetails": [

     {

     "TagName": "Weather.Auckland.Daily Cooling Degrees",

     "IsSelected": "false",

     "Order": "",

     "ColorIndex": "undefined",

     "Color": "#eeeeee"

     },

     {

     "TagName": "Weather.Auckland.Weather ID",

     "IsSelected": "true",

     "Order": "0",

     "ColorIndex": "1",

     "Color": "#AD1457"

     }

     ],

     "TimeAggregate": 3,

     "TimePreset": "OffsetInMilliSecs:1700224"

     },

     "ContentType": 1,

     "ChartType": "Column Chart",

     "Name": "Quarterly Report",

     "Keywords": [

     ],

     "Location": "/",

     "SharedMode": 98

     }

     }

7. Paste the resulting code (shown below in blue) in Powershell as a POST request.

   For the -Uri parameter, use the Request URL from step 7 (shown in red below).

   For example:

   $header = @{ "Content-Type"="application/json;charset=UTF-8" }; $postdata='{ "upsert": { "LayoutInfo": { "DashboardContents": [ ], "Layout": [ { "Type": "Status Board", "Name": "All Numeric", "IsActiveGroup": "true", "Tags": [ ], "UIProperties": "{\"version\":{\"major\":1,\"minor\":5,\"timestamp\":\"\"},\"selectedOptions\":{\"dates\":{\"from\":\"2018-12-01T00:00:00.000Z\",\"to\":\"2018-12-01T03:25:52.108Z\"},\"isCSVDownloadAllowed\":true}}" }, { "Type": "", "Name": "Minute", "IsActiveGroup": "false", "Tags": [ ], "UIProperties": "" }, { "Type": "", "Name": "Hour", "IsActiveGroup": "false", "Tags": [ ], "UIProperties": "" }, { "Type": "", "Name": "Second", "IsActiveGroup": "false", "Tags": [ ], "UIProperties": "" } ], "TagDetails": [ { "TagName": "SysTimeHour", "IsSelected": "true", "Order": "0", "ColorIndex": "0", "Color": "#03A9F4" }, { "TagName": "SysTimeMin", "IsSelected": "true", "Order": "1", "ColorIndex": "1", "Color": "#AD1457" }, { "TagName": "SysTimeSec", "IsSelected": "true", "Order": "2", "ColorIndex": "2", "Color": "#F57F17" } ], "TimeAggregate": 2, "TimePreset": 5 }, "ContentType": 1, "ChartType": "Status Board", "Name": "My Content", "Keywords": [ ], "Location": "", "SharedMode": 73 } }' try{ $response = Invoke-WebRequest -Uri http://localhost:32569/Historian/v2/Contents -Method Post -Body $PostData -Headers $header -ErrorVariable RespErr -UseDefaultCredentials $response; } catch [System.Net.WebException] { if($_.Exception.Response.StatusCode -eq "Conflict"){ Write-Host "It's a duplicate Content" }else{ Write-Host "The Request failed."; $respStream = $_.Exception.Response.GetResponseStream() $reader = New-Object System.IO.StreamReader($respStream) $ResponseContent = $reader.ReadToEnd(); $ResponseContent; $RespErr; } }
