Azure devops Azure DevOps如何通过REST API编辑Wiki页面

我想通过RESTAPI（Azure DevOps服务器2019.0.1）编辑Azure DevOps wiki页面

运行此PowerShell脚本时：

#VARIABLES
$api = "api-version=5.0"
$root = "http://136.202.18.216:8070/Samples"
$personalToken = "uwawlzqp6j7i1nd5dasspwkwp63tr2w2sxb5563zrla2bivynbza"

#AUTHORIZATION
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($personalToken)"))
$headers = @{
    "Authorization" = ('Basic {0}' -f $token)
    "If-Match"      = '*'
}

#PROJECT VARIABLES
$project = "Framework%20A"
$pageToUpdate = "/Seite2"

#BODY
$body = @"
    {
        "content": "Hello"
    }
"@

#GET
$url = "$root/$project/_apis/wiki/wikis/2e887fde-ce76-4180-aa8d-f26ed4799eb3/pages?version=wikiMaster&path=$pageToUpdate&includeContent=True&$api"
$content = Invoke-RestMethod -Uri $url -Method Get -ContentType "application/json" -Headers $headers
Write-Host "$($content.path) = $($content.content)" -ForegroundColor Yellow

#PUT
$url = "$root/$project/_apis/wiki/wikis/2e887fde-ce76-4180-aa8d-f26ed4799eb3/pages?version=wikiMaster&path=$pageToUpdate&$api"
$update = Invoke-RestMethod -Uri $url -Method Put -ContentType "application/json" -Headers $header -Body $body -Verbose
Write-Host $update.content -ForegroundColor Yellow
exit(0)

/Seite2 = Seite 2 Content

控制台输出为：

#VARIABLES
$api = "api-version=5.0"
$root = "http://136.202.18.216:8070/Samples"
$personalToken = "uwawlzqp6j7i1nd5dasspwkwp63tr2w2sxb5563zrla2bivynbza"

    "If-Match"      = '*'

第一行

/Seite2=Seite2 Content

是从我要编辑的页面成功获取

请求的结果。
put
请求发生错误。我做错了什么

更新：（工作示例）

在
If Match
标题中，您不能只将
'*'
放在那里，您需要将页面的
ETag
放在那里

你是怎么得到的？在第一次
GET
调用use
Invoke WebRequest
（instaed of
Invoke RestMethod
）中，现在在响应中还将得到headers响应，其中存在
ETag
：

$page = Invoke-WebRequest -Uri $url ...........
$etag = $page.Headers.ETag
$headers = @{
    "Authorizaion = ....."
    "If-Match" = $etag
}

现在，第二个
调用rest方法将用于更新页面。
非常感谢Shayki，我用工作示例更新了我的问题。向你问好。
