func Request ¶

func Request() (*http.Request, error)

Request returns the HTTP request as represented in the current environment. This assumes the current program is being run by a web server in a CGI environment. The returned Request's Body is populated, if applicable.

func RequestFromMap ¶

func RequestFromMap(params map[string]string) (*http.Request, error)

RequestFromMap creates an http.Request from CGI variables. The returned Request's Body field is not populated.

func Serve ¶

func Serve(handler http.Handler) error

Serve executes the provided Handler on the currently active CGI request, if any. If there's no current CGI environment an error is returned. The provided handler may be nil to use http.DefaultServeMux.

type Handler ¶

Handler runs an executable in a subprocess with a CGI environment.

type Handler struct {
    Path string // path to the CGI executable
    Root string // root URI prefix of handler or empty for "/"

    // Dir specifies the CGI executable's working directory.
    // If Dir is empty, the base directory of Path is used.
    // If Path has no base directory, the current working
    // directory is used.
    Dir string

    Env        []string    // extra environment variables to set, if any, as "key=value"
    InheritEnv []string    // environment variables to inherit from host, as "key"
    Logger     *log.Logger // optional log for errors or nil to use log.Print
    Args       []string    // optional arguments to pass to child process
    Stderr     io.Writer   // optional stderr for the child process; nil means os.Stderr

    // PathLocationHandler specifies the root http Handler that
    // should handle internal redirects when the CGI process
    // returns a Location header value starting with a "/", as
    // specified in RFC 3875 § 6.3.2. This will likely be
    // http.DefaultServeMux.
    //
    // If nil, a CGI response with a local URI path is instead sent
    // back to the client and not redirected internally.
    PathLocationHandler http.Handler
}
