HTTPRedirect

HTTPRedirect[uri]

represents an HTTP redirect to the specified uri.

HTTPRedirect[uri,metadata]

represents an HTTP redirect to uri with the specified metadata.

Details

  • The redirect location uri can be either a string representing an explicit URL or a CloudObject.
  • HTTPRedirect is usually stored in a CloudObject or specified as the result in an APIFunction or FormFunction.
  • HTTPRedirect[…] can be deployed to the cloud using CloudDeploy.
  • The metadata in HTTPRedirect is an association including the following possible elements:
  • "StatusCode"302HTTP status code
    "ContentType""text/html"MIME type for content
    "Cookies"{}cookies to set
    "Headers"Automatica list of rules giving HTTP response headers

Basic Examples  (1)

Redirect to a new URL:

Wolfram Language code: CloudDeploy @ Delayed[HTTPRedirect["http://www.wolfram.com/"]]

Use inside APIFunction:

Wolfram Language code: CloudDeploy @ APIFunction[ "url" -> "SemanticURL", Composition[HTTPRedirect, First] ]

Use inside FormFunction:

Wolfram Language code: CloudDeploy @ FormFunction[ "query" -> <|"Hint" -> "Search", "Label" -> None|>, HTTPRedirect[URLBuild["https://en.wikipedia.org/w/index.php", {"search" -> #query}]]& ]

Scope  (1)

By default, HTTPRedirect creates a redirect. A temporary redirect is not cached by the browser:

Wolfram Language code: CloudDeploy @ Delayed[ HTTPRedirect[URLBuild["http://www.wolfram.com", {"noonce" -> RandomInteger[{1, 2000}]}]] ]

Use a permanent redirect and the browser will cache the response:

Wolfram Language code: CloudDeploy @ Delayed[ HTTPRedirect[ URLBuild[ "http://www.wolfram.com", {"noonce" -> RandomInteger[{1, 2000}]} ], <|"StatusCode" -> 301|> ] ]

Neat Examples  (1)

Create a form function that is redirecting to a new URL:

Wolfram Language code: CloudDeploy[FormFunction[{"Website" -> <|"Interpreter" -> "SemanticURL", "Input" -> "Wikipedia"|>}, Composition[HTTPRedirect, First], AppearanceRules -> <|"Title" -> "WebGo!", "Description" -> "Write the name of any website, and we will take you there!", "SubmitLabel" -> "Go!"|>]]
