Detailed Description

The httprequest class provides methods for accessing components of the http request.

Member Function Documentation

◆ getAllValues()

const char *const * httprequest::getAllValues ( )

Returns a null terminated list of the values corresponding to the variables returned from getAllVariables().

◆ getAllVariableCount()

uint64_t httprequest::getAllVariableCount ( )

Returns the total number of variables - environment, parameters, files, and cookies.

◆ getAllVariables()

const char *const * httprequest::getAllVariables ( )

Returns a null terminated list of all variables. The order of the list is the order the variables were received in.

◆ getContentTypeIsAllowed()

virtual bool httprequest::getContentTypeIsAllowed	(	const char *	deniedcontenttypes,
		const char *	allowedcontenttypes )

virtual

Matches the CONTENT_TYPE environment variable against "deniedcontenttypes" and "allowedcontenttypes" (in that order) using regular expression syntax. Returns true if the content type of the data posted by the client is allowed and false otherwise.

This method may be overriden to provide customized content-type-based security.

◆ getCookie()

Returns a null terminated list of values corresponding to the variables returned from getCookieVariables().

◆ getCookieVariables()

const char *const * httprequest::getCookieVariables ( )

Returns a null terminated list of cookie variables. The order of the list is the order the variables were received in.

◆ getEnvironmentValues()

const char *const * httprequest::getEnvironmentValues ( )

Returns a null terminated list of environment variable values.

◆ getEnvironmentVariable()

const char * httprequest::getEnvironmentVariable ( const char * name )

Returns the value of the environment variable "name".

◆ getEnvironmentVariableCount()

uint64_t httprequest::getEnvironmentVariableCount ( )

Returns the number of environment variables.

◆ getEnvironmentVariables()

const char *const * httprequest::getEnvironmentVariables ( )

Returns a null terminated list of environment variables.

◆ getFileCount()

uint64_t httprequest::getFileCount ( )

Returns the number of posted files.

◆ getFileNames()

const char *const * httprequest::getFileNames ( )

Returns a null terminated list of file names. The order of the list is the order in which the file parameters were received.

◆ getFileParameterFileName()

Returns the filename of the local file created when file parameter "name" was passed in.

◆ getIpIsAllowed()

virtual bool httprequest::getIpIsAllowed	(	const char *	deniedips,
		const char *	allowedips )

virtual

Matches the REMOTE_ADDR environment variable against "deniedips" and "allowedips" (in that order) using regular expression syntax. Returns true if the client's IP address is allowed and false otherwise.

This method may be overriden to provide customized ip-based security.

◆ getMethodIsAllowed()

virtual bool httprequest::getMethodIsAllowed	(	const char *	deniedmethods,
		const char *	allowedmethods )

virtual

Matches the REQUEST_METHOD environment variable against "deniedmethods" and "allowedmethods" (in that order) using regular expression syntax. Returns true if the request method used by the client is allowed and false otherwise.

This method may be overriden to provide customized request-method-based security.

Returns all parameters formatted as an escaped get string into "container" with the exception of a NULL terminated list of exceptions. If "container" is NULL, the list is written to the browser.

◆ getParametersAsHiddenVariables()

void httprequest::getParametersAsHiddenVariables	(	output *	container,
		const char const	excepcions )

Returns all parameters formatted as a list of hidden variables into "container" with the exception of a NULL terminated list of exceptions passed in after "container". If "container" is NULL, the list is written to the browser.

◆ getParameterValues()

const char *const * httprequest::getParameterValues ( )

Returns a null terminated list of values corresponding to the variables returned from getParameterVariables().

◆ getParameterVariables()

const char *const * httprequest::getParameterVariables ( )

virtual

Matches the HTTP_REFERER environment variable against "deniedreferers" and "allowedreferers" (in that order) using regular expression syntax. Returns true if the referrer is permitted and false otherwise.

This method may be overriden to provide customized referrer-based security.

◆ getRequiredParametersWereProvided()

bool httprequest::getRequiredParametersWereProvided ( parameterrequirement ** pr )

Reads through the NULL terminated list of parameter requirements. Returns true if the parameters meet the requirements and false if they did not.

Each parameterrequirement contains a parameter variable name and a boolean value indicating whether that variable can be empty or not.

For example. The following call requires that "first", "last", "address", "city", "state" and "phone" be present but allows "address", "city" and "state" to be blank.

parameterrequirement *pr[]={{"first",false}, {"last",false}, {"address",true}, {"city",true}, {"state",true}, {"phone",false}, NULL}; success=requiredParameters(pr);
