Methods

__init__()

Not associated with other mapscript classes. Serves as a message intermediary between an application and MapServer’s OWS capabilities. Using it permits creation of lightweight WMS services.

addParameter(name: char, value: char) → void

Add a request parameter, even if the parameter key was previously set. This is useful when multiple parameters with the same key are required. For example: request.addParameter(“SIZE”, “x(100)”) request.addParameter(“SIZE”, “y(100)”)

getName(index: int) → char

Return the name of the parameter at index in the request’s array of parameter names.

getValue(index: int) → char

Return the value of the parameter at index in the request’s array of parameter values.

getValueByName(name: char const) → char

Return the value associated with the parameter name

loadParams() → int

Initializes the OWSRequest object from the cgi environment variables REQUEST_METHOD, QUERY_STRING and HTTP_COOKIE. Returns the number of name/value pairs collected. Warning: most errors will result in a process exit!

loadParamsFromPost(postData: char, url: char const) → int

Initializes the OWSRequest object with POST data, along with a the provided URL which is treated like a QUERY_STRING. Note that REQUEST_METHOD=POST and the caller is responsible for setting the correct content type e.g. req.contenttype = "application/xml"

loadParamsFromURL(url: char const) → int

Initializes the OWSRequest object from the provided URL which is treated like a QUERY_STRING. Note that REQUEST_METHOD=GET and no post data is assumed in this case.

setParameter(name: char, value: char) → void

Set a request parameter. For example:

request.setParameter(“REQUEST”, “GetMap”) request.setParameter(“BBOX”, “-107.0,40.0,-106.0,41.0”)
