Example 2

$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"}}

Example 3: Pass multiple headers

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

Example 3: Submitting form data

$R = Invoke-WebRequest https://website.com/login.aspx
$R.Forms[0].Name = "MyName"
$R.Forms[0].Password = "MyPassword"
Invoke-RestMethod https://website.com/service.aspx -Body $R.Forms[0]

Example 4: Enumerate returned items on the pipeline

$uri = 'https://api.github.com/repos/microsoftdocs/powershell-docs/issues'
$x = 0
Invoke-RestMethod -Uri $uri | ForEach-Object { $x++ }
$x
1

$x = 0
(Invoke-RestMethod -Uri $uri) | ForEach-Object { $x++ }
$x
30

$x = 0
Invoke-RestMethod -Uri $uri | Write-Output | ForEach-Object { $x++ }
$x
30

Parámetros

-Body

Specifies the body of the request. The body is the content of the request that follows the headers. You can also pipe a body value to Invoke-RestMethod.

The Body parameter can be used to specify a list of query parameters or specify the content of the response.

When the input is a GET request, and the body is an IDictionary (typically, a hash table), the body is added to the URI as query parameters. For other request types (such as POST), the body is set as the value of the request body in the standard name=value format.

-Certificate

Specifies the client certificate that's used for a secure web request. Enter a variable that contains a certificate or a command or expression that gets the certificate.

To find a certificate, use Get-PfxCertificate or use the Get-ChildItem cmdlet in the Certificate (Cert:) drive. If the certificate isn't valid or doesn't have sufficient authority, the command fails.

Conjuntos de parámetros

-CertificateThumbprint

Specifies the digital public key certificate (X509) of a user account that has permission to send the request. Enter the certificate thumbprint of the certificate.

Certificates are used in client certificate-based authentication. Certificates can only be mapped only to local user accounts, not ___domain accounts.

To see the certificate thumbprint, use the Get-Item or Get-ChildItem command to find the certificate in Cert:\CurrentUser\My.

Propiedades del parámetro

Conjuntos de parámetros

-ContentType

Specifies the content type of the web request.

If the value for ContentType contains the encoding format (as charset), the cmdlet uses that format to encode the body of the web request. If the ContentType doesn't specify an encoding format, the default encoding format is used instead. An example of a ContentType with an encoding format is text/plain; charset=iso-8859-5, which specifies the Latin/Cyrillic alphabet.

If you omit the parameter, the content type may be different based on the HTTP method you use:

• For a POST method, the content type is application/x-www-form-urlencoded
• For a PUT method, the content type is application/json
• For other methods, the content type isn't specified in the request

If you are using the InFile parameter to upload a file, you should set the content type. Usually, the type should be application/octet-stream. However, you need to set the content type based on the requirements of the endpoint.

-Credential

Specifies a user account that has permission to send the request. The default is the current user.

Type a user name, such as User01 or Domain01\User01, or enter a PSCredential object generated by the Get-Credential cmdlet.

Credentials are stored in a PSCredential object and the password is stored as a SecureString.

-DisableKeepAlive

Sets the KeepAlive value in the HTTP header to False. By default, KeepAlive is True. KeepAlive establishes a persistent connection to the server to facilitate subsequent requests.

-Headers

Specifies the headers of the web request. Enter a hash table or dictionary.

To set UserAgent headers, use the UserAgent parameter. You cannot use this parameter to specify UserAgent or cookie headers.

-InFile

Gets the content of the web request body from a file. Enter a path and filename. If you omit the path, the default is the current ___location.

You also need to set the content type of the request. For example, to upload a file you should set the content type. Usually, the type should be application/octet-stream. However, you need to set the content type based on the requirements of the endpoint.

-MaximumRedirection

Determines how many times Windows PowerShell redirects a connection to an alternate Uniform Resource Identifier (URI) before the connection fails. The default value is 5. A value of 0 (zero) prevents all redirection.

-Method

Specifies the method used for the web request. The acceptable values for this parameter are:

• Default
• Delete
• Get
• Head
• Merge
• Options
• Patch
• Post
• Put
• Trace

-OutFile

Saves the response body in the specified output file. Enter a path and file name. If you omit the path, the default is the current ___location.

By default, Invoke-RestMethod returns the results to the pipeline.

Conjuntos de parámetros

-PassThru

This parameter is valid only when the OutFile parameter is also used in the command. The intent is to have the results written to the file and to the pipeline.

Propiedades del parámetro

-Proxy

Uses a proxy server for the request, rather than connecting directly to the Internet resource. Enter the URI of a network proxy server.

Propiedades del parámetro

Conjuntos de parámetros

-ProxyCredential

Specifies a user account that has permission to use the proxy server that's specified by the Proxy parameter. The default is the current user.

Type a user name, such as "User01" or "Domain01\User01", or enter a PSCredential object, such as one generated by the Get-Credential cmdlet.

This parameter is valid only when the Proxy parameter is also used in the command. You can't use the ProxyCredential and ProxyUseDefaultCredentials parameters in the same command.

Propiedades del parámetro

Conjuntos de parámetros

-ProxyUseDefaultCredentials

Uses the credentials of the current user to access the proxy server that is specified by the Proxy parameter.

This parameter is valid only when the Proxy parameter is also used in the command. You can't use the ProxyCredential and ProxyUseDefaultCredentials parameters in the same command.

Propiedades del parámetro

Conjuntos de parámetros

-SessionVariable

Creates a variable containing the web request session. Enter a variable name without the dollar sign ($) symbol.

When you specify a session variable, Invoke-RestMethod creates a web request session object and assigns it to a variable with the specified name in your PowerShell session. You can use the variable in your session as soon as the command completes.

Unlike a remote session, the web request session isn't a persistent connection. It's an object that contains information about the connection and the request, including cookies, credentials, the maximum redirection value, and the user agent string. You can use it to share state and data among web requests.

To use the web request session in subsequent web requests, specify the session variable in the value of the WebSession parameter. PowerShell uses the data in the web request session object when establishing the new connection. To override a value in the web request session, use a cmdlet parameter, such as UserAgent or Credential. Parameter values take precedence over values in the web request session.

You can't use the SessionVariable and WebSession parameters in the same command.

-TimeoutSec

Specifies how long the request can be pending before it times out. Enter a value in seconds. The default value, 0, specifies an indefinite time-out.

A Domain Name System (DNS) query can take up to 15 seconds to return or time out. If your request contains a host name that requires resolution, and you set TimeoutSec to a value greater than zero, but less than 15 seconds, it can take 15 seconds or more before a WebException is thrown, and your request times out.

Specifies a value for the transfer-encoding HTTP response header. The acceptable values for this parameter are:

• Chunked
• Compress
• Deflate
• GZip
• Identity

-Uri

Specifies the Uniform Resource Identifier (URI) of the internet resource to which the web request is sent. This parameter supports HTTP, HTTPS, FTP, and FILE values.

This parameter is required. The parameter name (Uri) is optional.

-UserAgent

Specifies a user agent string for the web request.

The default user agent is similar to Mozilla/5.0 (Windows NT 10.0; Microsoft Windows 10.0.15063; en-US) PowerShell/6.0.0 with slight variations for each operating system and platform.

To test a website with the standard user agent string that's used by most internet browsers, use the properties of the PSUserAgent class, such as Chrome, Firefox, InternetExplorer, Opera, and Safari.

-WebSession

Specifies a web request session. Enter the variable name, including the dollar sign ($).

To override a value in the web request session, use a cmdlet parameter, such as UserAgent or Credential. Parameter values take precedence over values in the web request session.

Unlike a remote session, the web request session isn't a persistent connection. It's an object that contains information about the connection and the request, including cookies, credentials, the maximum redirection value, and the user agent string. You can use it to share state and data among web requests.

To create a web request session, enter a variable name, without a dollar sign, in the value of the SessionVariable parameter of an Invoke-RestMethod command. Invoke-RestMethod creates the session and saves it in the variable. In subsequent commands, use the variable as the value of the WebSession parameter.

You can't use the SessionVariable and WebSession parameters in the same command.
