在here-string标题之后但在行结束之前不允许使用任何字符

Question

我使用它作为我脚本的基础：

https://www.nwcadence.com/blog/vststfs-rest-api-the-basics-and-working-with-builds-and-releases

我的脚本如下

Param(
   [string]$vstsAccount = "abc",
   [string]$projectName = "abc",
   [string]$user = "",
   [string]$token = "xyz"
)

# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))

$verb = "POST"


$body = @"{

    "definition": {
         "id": 20
    }
}"@


$uri = "https://$($vstsAccount).visualstudio.com/DefaultCollection/$($projectName)/_apis/build/builds?api-version=4.1"
$result = Invoke-RestMethod -Uri $uri -Method $verb -ContentType "application/json" -Body (ConvertTo-Json $body)  -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}

但是我在上面的博客文章中使用的身体定义上有语法错误。

Answer 1

错误消息为您提供了线索：＆＃34;在here-string标题之后但在结束之前不允许使用任何字符＆＃34;

更改代码，以便here-string开头/结尾标记不会立即跟随/先于任何内容：

$body = @"
{

    "definition": {
         "id": 20
    }
}
"@

Answer 2

您可以通过多种方式更改here-string（$body变量的值）：

选项1：

$body = @{
definition = @{
id = 20    
}
}

选项2：

$body = @"
{

    "definition": {
         "id": 20
    }
}
"@

作为boxdog意思。

选项3：

$body = '
{

    "definition": {
         "id": 20
    }
}
'
