Functions ¶
func AppNameOrPort ¶ added in v0.8.15
AppNameOrPort takes a string and returns either the input string or a port number.
func Forbidden ¶ added in v0.5.10
func Forbidden(rw http.ResponseWriter)
func InternalServerError ¶ added in v0.8.10
func InternalServerError(rw http.ResponseWriter, err error)
func IsWebsocketUpgrade ¶ added in v0.8.10
func ParseCustom ¶ added in v0.7.5
func ParseCustom[T any](parser *QueryParamParser, vals url.Values, def T, queryParam string, parseFunc func(v string) (T, error)) T
ParseCustom has to be a function, not a method on QueryParamParser because generics cannot be used on struct methods.
func Read ¶
func Read(rw http.ResponseWriter, r *http.Request, value interface{}) bool
Read decodes JSON from the HTTP request into the value provided. It uses go-validator to validate the incoming request body.
func RequestHost ¶ added in v0.8.10
RequestHost returns the name of the host from the request. It prioritizes 'X-Forwarded-Host' over r.Host since most requests are being proxied.
func ResourceNotFound ¶ added in v0.7.0
func ResourceNotFound(rw http.ResponseWriter)
ResourceNotFound is intentionally vague. All 404 responses should be identical to prevent leaking existence of resources.
func SplitSubdomain ¶ added in v0.8.15
SplitSubdomain splits a subdomain from the rest of the hostname. E.g.:
- "foo.bar.com" becomes "foo", "bar.com"
- "foo.bar.baz.com" becomes "foo", "bar.baz.com"
An error is returned if the string doesn't contain a period.
func StripCoderCookies ¶ added in v0.8.6
StripCoderCookies removes the session token from the cookie header provided.
func UsernameFrom ¶ added in v0.8.2
UsernameFrom returns a best-effort username from the provided string.
It first attempts to validate the incoming string, which will be returned if it is valid. It then will attempt to extract the username from an email address. If no success happens during these steps, a random username will be returned.
func UsernameValid ¶ added in v0.8.2
UsernameValid returns whether the input string is a valid username.
func WebsocketCloseSprintf ¶
WebsocketCloseSprintf formats a websocket close message and ensures it is truncated to the maximum allowed length.
func Write ¶
func Write(rw http.ResponseWriter, status int, response interface{})
Write outputs a standardized format to an HTTP response body.
Types ¶
type ApplicationURL ¶ added in v0.8.15
type ApplicationURL struct { // Only one of AppName or Port will be set. AppName string Port uint16 AgentName string WorkspaceName string Username string // BaseHostname is the rest of the hostname minus the application URL part // and the first dot. BaseHostname string }
ApplicationURL is a parsed application URL hostname.
func ParseSubdomainAppURL ¶ added in v0.8.15
func ParseSubdomainAppURL(hostname string) (ApplicationURL, error)
ParseSubdomainAppURL parses an ApplicationURL from the given hostname. If the subdomain is not a valid application URL hostname, returns a non-nil error.
Subdomains should be in the form:
{PORT/APP_NAME}--{AGENT_NAME}--{WORKSPACE_NAME}--{USERNAME} (eg. http://8080--main--dev--dean.hi.c8s.io)
func (ApplicationURL) String ¶ added in v0.8.15
func (a ApplicationURL) String() string
String returns the application URL hostname without scheme.
type QueryParamParser ¶ added in v0.7.0
type QueryParamParser struct { // Errors is the set of errors to return via the API. If the length // of this set is 0, there are no errors!. Errors []codersdk.ValidationError }
QueryParamParser is a helper for parsing all query params and gathering all errors in 1 sweep. This means all invalid fields are returned at once, rather than only returning the first error
func NewQueryParamParser ¶ added in v0.7.0
func NewQueryParamParser() *QueryParamParser
type StatusWriter ¶ added in v0.8.10
type StatusWriter struct { http.ResponseWriter Status int Hijacked bool // contains filtered or unexported fields }
StatusWriter intercepts the status of the request and the response body up to maxBodySize if Status >= 400. It is guaranteed to be the ResponseWriter directly downstream from Middleware.
func (*StatusWriter) Hijack ¶ added in v0.8.10
func (w *StatusWriter) Hijack() (net.Conn, *bufio.ReadWriter, error)
func (*StatusWriter) ResponseBody ¶ added in v0.8.10
func (w *StatusWriter) ResponseBody() []byte
func (*StatusWriter) WriteHeader ¶ added in v0.8.10
func (w *StatusWriter) WriteHeader(status int)
