GenerateHTTPResponse
GenerateHTTPResponse[expr]
gives the HTTPResponse object that is generated when a cloud object containing expr is requested on the web.
GenerateHTTPResponse[expr,req]
gives the response for the HTTP request specified by req.
Details
- GenerateHTTPResponse effectively simulates the behavior of the Wolfram Engine cloud server.
- GenerateHTTPResponse can be used both locally on a desktop system and in the cloud. Certain operations that require extended cloud infrastructure are not supported by GenerateHTTPResponse on local desktop systems.
- The expression expr can contain any of the heads used in CloudDeploy, such as Delayed, FormFunction, etc.
- In GenerateHTTPResponse[expr,req], the request req can be an association of the form returned by HTTPRequestData[] or an explicit URL in the form "url" or URL["url"].

Apply GenerateHTTPResponse to Delayed to locally simulate a cloud server:
GenerateHTTPResponse[Delayed[2 + 2, "WL"]]%["Body"]GenerateHTTPResponse recurses on the expression until it returns an HTTPResponse:
GenerateHTTPResponse[Delayed[If[RandomReal[] < 0.5, APIFunction["x" -> "String", StringLength[#x]&], FormFunction["x" -> "String"]]]]You can use an explicit HTTPResponse to set the StatusCode or the headers of the response:
GenerateHTTPResponse[HTTPResponse[ExportForm[<|"Error" -> True|>, "JSON"], <|"StatusCode" -> 500|>]]Use ResponseForm to get a detailed report on the computation you've run:
GenerateHTTPResponse[ResponseForm[1 / 0, "WL"]]
%["Body"]Scope (3)
You can use the second argument to set the details of the HTTP request:
GenerateHTTPResponse[APIFunction["x" -> "Number", #x ^ 2&], {"Query" -> {"x" -> "2"}}]%["Body"]If the data does not conform to the API specification, the status code is 400:
GenerateHTTPResponse[APIFunction["x" -> "Number", #x ^ 2&], {"Query" -> {"x" -> "f"}}]Use a URL object for the request URL:
GenerateHTTPResponse[2, URL["http://wolfram.com"]]
