我们正在尝试测试和评估来自 Microsoft 认知服务的文本分析 API。我们正在尝试使用 Invoke-RestMethod 让快速而肮脏的 PowerShell 脚本正常工作。经过一些调整后,我们仍然收到 400 个错误返回给我们。我们不确定出了什么问题,因为 JSON 似乎已更正,并且我们输入的 API key 似乎是正确的。我们利用了我们在另一个人的博客上找到的关于使用附加标题的内容,并尝试了一些变体,但仍然没有骰子。有人可以为我们做一个健全性检查吗?

#html tag stripper function
function htmlStrip ($results)
{
#using .NET toString method to ensure PS doesn't interpret same var incorrectly
$results = $results.toString()
$results -replace '<[^>]*(>|$)'
}


Try
{


[string]$sourceUrl = Read-Host "Enter a URL such as https://foobar.com"
}
Catch
{
Write-Host "URL requires http:// or https:// prefix e.g. https://cnn.com"
}


$webClient = New-Object Net.WebClient
[string]$results = $webClient.DownloadString($sourceUrl)


[string]$cleanResults = htmlStrip $results


$body =
[ordered]@{"documents" =
@{ "language" = "en"; "id" = $sourceUrl; "text" = $cleanResults }
}

#>

$body = [ordered]@{
"documents" =
@(
@{ "language" = "en"; "id" = $sourceUrl; "text" = $cleanResults }
)
}

$jsonBody = $body | ConvertTo-Json

#Begin Text Analytics API Call with Invoke-RestMethod wrapper
#[string]$apiUrl = "https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/keyPhrases"
[string]$apiKey = "REDACTED"


$headers = @{ "Ocp-Apim-Subscription-Key" = $apiKey }

$analyticsResults = Invoke-RestMethod -Method Post -Uri $apiUrl -Headers $headers -Body $jsonBody -ContentType "application/json" -ErrorAction Stop

Write-Host $analyticsResults

Write-Host $jsonBody

最佳答案

您放入 text 的数据您请求的属性可能无效。
我用 GitHub 上 TypeScript 存储库的 README.md 的修复 URL 尝试了你的脚本,它可以工作。

您的脚本(略短)

$sourceUrl = 'https://raw.githubusercontent.com/Microsoft/TypeScript/master/README.md'

$webClient = New-Object Net.WebClient
$results = $webClient.DownloadString($sourceUrl)

$body = [ordered]@{
"documents" =
@(
@{ "language" = "en"; "id" = $sourceUrl; "text" = $results }
)
}

$jsonBody = $body | ConvertTo-Json

$apiUrl = "https://westus.api.cognitive.microsoft.com/text/analytics/v2.0/keyPhrases"
$apiKey = "..."

$headers = @{ "Ocp-Apim-Subscription-Key" = $apiKey }

$analyticsResults = Invoke-RestMethod -Method Post -Uri $apiUrl -Headers $headers -Body $jsonBody -ContentType "application/json" -ErrorAction Stop
$analyticsResults.documents.keyPhrases

结果
TypeScript compiler
gulp tests
g typescript
TypeScript source
built compiler
TypeScript users
g gulp
TypeScript directory
cd TypeScript
gulp baseline
gulp lint
gulp local
gulp clean
gulp runtests-browser
gulp LKG
Install Gulp tools
...
