说明

Invoke-RestMethod cmdlet 将 HTTP 和 HTTPS 请求发送到返回丰富结构化数据的代表性状态传输 （REST） Web 服务。

Windows PowerShell 基于数据类型设置响应的格式。 对于 RSS 或 ATOM 源，Windows PowerShell 返回 Item 或 Entry XML 节点。 对于 JavaScript 对象表示法（JSON）或 XML，Windows PowerShell 会将内容转换为对象（或反序列化）。

此 cmdlet 在 Windows PowerShell 3.0 中引入。

示例

示例 1：获取 PowerShell RSS 源

Invoke-RestMethod -Uri https://blogs.msdn.microsoft.com/powershell/feed/ |
  Format-Table -Property Title, pubDate

Title                                                                pubDate
-----                                                                -------

此命令使用 Invoke-RestMethod cmdlet 从 PowerShell 博客 RSS 源获取信息。 该命令使用 Format-Table cmdlet 显示 标题 的值，并 pubDate 表中每个博客的属性。

示例 2

在以下示例中，用户运行 Invoke-RestMethod，在用户的组织中 Intranet 网站上执行 POST 请求。

$Cred = Get-Credential

# Next, allow the use of self-signed SSL certificates.

[System.Net.ServicePointManager]::ServerCertificateValidationCallback = { $True }

# Create variables to store the values consumed by the Invoke-RestMethod command.
# The search variable contents are later embedded in the body variable.

$Server = 'server.contoso.com'
$Url = "https://${server}:8089/services/search/jobs/export"
$Search = "search index=_internal | reverse | table index,host,source,sourcetype,_raw"

# The cmdlet handles URL encoding. The body variable describes the search criteria, specifies CSV as the output mode, and specifies a time period for returned data that starts two days ago and ends one day ago. The body variable specifies values for parameters that apply to the particular REST API with which Invoke-RestMethod is communicating.

$Body = @{
    search = $Search
    output_mode = "csv"
    earliest_time = "-2d@d"
    latest_time = "-1d@d"
}

# Now, run the Invoke-RestMethod command with all variables in place, specifying a path and file name for the resulting CSV output file.

Invoke-RestMethod -Method Post -Uri $url -Credential $Cred -Body $body -OutFile output.csv

{"preview":true,"offset":0,"result":{"sourcetype":"contoso1","count":"9624"}}

{"preview":true,"offset":1,"result":{"sourcetype":"contoso2","count":"152"}}

{"preview":true,"offset":2,"result":{"sourcetype":"contoso3","count":"88494"}}

{"preview":true,"offset":3,"result":{"sourcetype":"contoso4","count":"15277"}}

示例 3：传递多个标头

$headers = @{
    'userId' = 'UserIDValue'
    'token' = 'TokenValue'
}
Invoke-RestMethod -Uri $uri -Method Post -Headers $headers -Body $body

API 通常需要通过的标头进行身份验证、验证等。

此示例演示了如何将多个标头从 hash-table 传递到 REST API。

参数

-Body

-Certificate

-CertificateThumbprint

-ContentType

-Credential

-DisableKeepAlive

-Headers

-InFile

-MaximumRedirection

-Method

-OutFile

-PassThru

-Proxy

-ProxyCredential

-ProxyUseDefaultCredentials

-SessionVariable

-TimeoutSec

-TransferEncoding

-Uri

-UseBasicParsing

-UseDefaultCredentials

-UserAgent

-WebSession

输入

Object

可以通过管道将 Web 请求的正文传递给 Invoke-RestMethod。

输出

System.Xml.XmlDocument, Microsoft.PowerShell.Commands.HtmlWebResponseObject, System.String

cmdlet 的输出取决于检索的内容的格式。

PSObject

如果请求返回 JSON 字符串，Invoke-RestMethod 返回表示字符串的 PSObject。
