json - 将 curl 命令转换为 Powershell

Question

我可以使用 curl 调用 REST api

curl  -H 'Authorization: Bearer <token>' \
      -H 'Accept: application/json' \
      -H 'Content-Type: application/json' \
      -X POST \
      -d '<json>' \
      https://api.dnsimple.com/v2/1010/zones/example.com/records

并且 json 需要采用以下格式:

{
  "name": "",
  "type": "MX",
  "content": "mxa.example.com",
}

如何使用 Invoke-WebRequest 调用此 API？我正在尝试以下(当然我在这里使用变量)当我调用它时，我收到错误 400

$uri =  [string]::Format("https://api.dnsimple.com/v2/{0}/zones/{1}/records",$account,$domain)
$headers = @{}
$headers["Authorization"] = [string]::Format("Bearer {0}", $token)
$headers["Accept"] = "application/json"
$headers["Content-Type"] = "application/json"

$json = @{}
$json["name"] = $subdomain
$json["type"] = "A"
$json["content"] = $ip

Invoke-WebRequest -Uri $uri -Body $json -Headers $headers -Method Post

问题似乎是您将原始哈希表传递给 -Body参数，而不是实际有效的 JSON 字符串。使用ConvertTo-Json为了这。此外，无需使用 [string]::Format()明确地，您可以使用 -f而是运营商!

$uri = 'https://api.dnsimple.com/v2/{0}/zones/{1}/records' -f $account,$domain
$headers = @{
  Authorization = 'Bearer {0}' -f $token
  Accept        = 'application/json'
  Content-Type  = 'application/json'
}
$json = @{
  name    = "$subdomain"
  type    = "A"
  content = "$ip"
} |ConvertTo-Json
Invoke-WebRequest -Uri $uri -Body $json -Headers $headers -Method Post
