Method Detail

create

static CorsHandler create(String allowedOriginPattern)

Create a CORS handler using a regular expression to match origins. An origin follows rfc6454#section-7 and is expected to have the format: <scheme> "://" <hostname> [ ":" <port> ]

Parameters:

allowedOriginPattern - the allowed origin pattern

Returns:

the handler

create

static CorsHandler create()

Create a empty CORS handler that allows * origin.

Returns:

the handler

addOrigin

CorsHandler addOrigin(String origin)

Add an origin to the list of allowed Origins. An origin follows rfc6454#section-7 and is expected to have the format: <scheme> "://" <hostname> [ ":" <port> ]

Parameters:

origin - the well formatted static origin

Returns:

self

addOrigins

CorsHandler addOrigins(List<String> origins)

Set the list of allowed origins. An origin follows rfc6454#section-7 and is expected to have the format: <scheme> "://" <hostname> [ ":" <port> ]

Parameters:

origins - the well formatted static origin list

Returns:

self

allowedMethod

CorsHandler allowedMethod(HttpMethod method)

Add an allowed method

Parameters:

method - the method to add

Returns:

a reference to this, so the API can be used fluently

allowedMethods

CorsHandler allowedMethods(Set<HttpMethod> methods)

Add a set of allowed methods

Parameters:

methods - the methods to add

Returns:

a reference to this, so the API can be used fluently

allowedHeader

CorsHandler allowedHeader(String headerName)

Add an allowed header

Parameters:

headerName - the allowed header name

Returns:

a reference to this, so the API can be used fluently

allowedHeaders

CorsHandler allowedHeaders(Set<String> headerNames)

Add a set of allowed headers

Parameters:

headerNames - the allowed header names

Returns:

a reference to this, so the API can be used fluently

exposedHeader

CorsHandler exposedHeader(String headerName)

Add an exposed header

Parameters:

headerName - the exposed header name

Returns:

a reference to this, so the API can be used fluently

exposedHeaders

CorsHandler exposedHeaders(Set<String> headerNames)

Add a set of exposed headers

Parameters:

headerNames - the exposed header names

Returns:

a reference to this, so the API can be used fluently

allowCredentials

CorsHandler allowCredentials(boolean allow)

Set whether credentials are allowed. Note that user agents will block requests that use a wildcard as origin and include credentials. From the MDN documentation you can read:

Important note: when responding to a credentialed request, server must specify a domain, and cannot use wild carding.

Parameters:

allow - true if allowed

Returns:

a reference to this, so the API can be used fluently

maxAgeSeconds

CorsHandler maxAgeSeconds(int maxAgeSeconds)

Set how long the browser should cache the information

Parameters:

maxAgeSeconds - max age in seconds

Returns:

a reference to this, so the API can be used fluently
