Developing WebSpeed Applications

General information exchange

WebSpeed supports several generally useful API functions for information exchange, some of which are most commonly used to handle Web requests. Table 3–7 lists these functions.

Table 3–7: General information exchange API functions 

Function	Return type	Description
get-cgi	CHARACTER	Returns the value of a specified CGI variable, or returns the list of all CGI variables if the specified variable name has the Unknown value (?). Returns blank (“ “) if the name is invalid.
get-field	CHARACTER	Returns the associated value for a specified form field or query string, or returns the list of all form fields in the current request if the specified field name has the Unknown value (?). Returns blank (“ “) if the name is invalid.
get-value	CHARACTER	Returns the first available value associated with the name of a user field, a form field, a query string, or a cookie. If the specified name has the Unknown value (?), returns the list of all user fields, form fields, and cookies. Returns blank (“ “) if the name is invalid. This is the most commonly used API function.
html-encode	CHARACTER	Converts various ASCII characters in a string to their HTML representation. Returns the HTML-encoded string. This function is useful for constructing HTML output from SpeedScript program data. However, do not execute it more than once for a given string to avoid corrupting the encoding.

See install-path/src/web/method/cgiutils.i for definitions of these functions.
