使用VSTS Rest API，如何更新Markdown小部件? [英] Using VSTS Rest API, how do you Update a Markdown widget?

问题描述

我正在尝试使用此REST API 来更新VSTS仪表板上的"Markdown"小部件.

I'm trying to use this REST API to Update a "Markdown" widget on a dashboard in VSTS.

使用下面的JSON主体，按示例获取Value cannot be null(请参见下文)?

Using the below JSON body, per the sample, I'm getting Value cannot be null (see below)?

Invoke-RestMethod:{"$ id":"1"，"innerException":null，"message":"Value 不能为null.\ r \ n参数名称: widget，" typeName:" System.ArgumentNullException，mscorlib，" typeKey:" ArgumentNullException，" errorCode:0，" eventId:0} C:\ Users \ alex \ OneDrive \ Documents \ Scripts \ VSTSPowershell \ VSTSAuthenticateAndInvoke.ps1:36 char:23+ ... $ result =调用RestMethod -Uri $ uri -Method $ method -ContentType ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~ + CategoryInfo:InvalidOperation:(System.Net.HttpWebRequest:HttpWebRequest)[Invoke-RestMethod]， WebException + FullyQualifiedErrorId: WebCmdletWebResponseException，Microsoft.PowerShell.Commands.InvokeRestMethodCommand

Invoke-RestMethod : {"$id":"1","innerException":null,"message":"Value cannot be null.\r\nParameter name: widget","typeName":"System.ArgumentNullException,mscorlib","typeKey":"ArgumentNullException","errorCode":0,"eventId":0}At C:\Users\alex\OneDrive\Documents\Scripts\VSTSPowershell\VSTSAuthenticateAndInvoke.ps1:36 char:23+ ... $result = Invoke-RestMethod -Uri $uri -Method $method -ContentType ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

我的目标仅仅是找到&使用新的显示内容更新Markdown小部件.这是一个新创建的小部件，所以eTag=1是我通过Get Dashboard和WidgetId进行验证的，而eTag=35是Dashboard.

My goal is simply to find & update a Markdown widget with new display content. It's a newly created widget, so eTag=1, which I verified with a Get Dashboard along with the WidgetId, and the eTag=35 is what the Dashboard is.

推荐答案

更改此行:

"size": {"rowSpan":2; "columnSpan":2},

到

"size": {"rowSpan":2, "columnSpan":2},
