Question

我有以下抛出异常的PowerShell脚本，如下所示。如何Invoke-RestMethod -Method Post授权$bearerHeader？

$content = New-Object System.Net.Http.StreamContent $snapshot;
$content.CopyToAsync($snapshot);
try {
    $encodedPath = [Text.Encoding]::ASCII.GetBytes($this.snapshotPath)
    $hmacsha = New-Object System.Security.Cryptography.HMACSHA512
    $hmacsha.key = [Convert]::FromBase64String($this.apikey);
    $bearerToken = $hmacsha.ComputeHash($encodedPath)

    $bearerToken = [Convert]::ToBase64String($bearerToken)
    $bearerToken = $bearerToken.Split('=')[0]
    $bearerToken = $bearerToken.Replace('*', '-')
    $bearerToken = $bearerToken.Replace('+', '_')

    $bearerHeader = @{ "Authorization" = ("Bearer", $bearerToken -join " ") }
    $url = ($this.baseAddress, $this.snapshotPath -join "");
    $resp = Invoke-RestMethod -Method Post -Uri $this.snapshotPath -ContentType "application/octet-stream" -Body $content -Headers $bearerToken
} catch [Exception] {
    Write-Host "Exception: "$_.Exception.Message -ForegroundColor Red;
}

无法将“System.String”类型的“uZZETvpJdAIqIH_235oFjan3wS_M582332jmiJjm23jJvJxJwHm0JtWSkhg5qj_7jGDI_s3IFx2ozx5wyQXCA”值转换为“System.Collections.IDictionary”类型。

根据评论，这个：

$resp = Invoke-RestMethod -Method Post -Uri $this.snapshotPath -ContentType "application/octet-stream" -Body $content -Headers $bearerToken

需要：

$resp = Invoke-RestMethod -Method Post -Uri $this.snapshotPath -ContentType "application/octet-stream" -Body $content -Headers $bearerHeader

-Headers参数需要一个哈希表作为其输入，您的代码将其创建为$ bearerHeader但是您没有使用它。

为什么此PowerShell Invoke-RestMethod POST会抛出异常？
