--- title: RequestContext --- # RequestContext View Source ## Summary A context object that contains information about the current request. Every request handler or middleware in the lifecycle of a request receives the same context object. ## Signature ```ts class RequestContext { constructor(request: Request): RequestContext; // Properties headers: Headers; method: RequestMethod; params: params; request: Request; url: URL; // Accessors get router(): Router>; // Methods get(key: key): ResolveContextEntryValue; has(key: key): boolean; set(key: key, value: ContextValue): void; } ``` ## Constructor Params ### request The incoming request ## Properties ### headers The headers of the request. ### method The request method. This may differ from `request.method` when using the `methodOverride` middleware, which allows HTML forms to simulate RESTful API request methods like `PUT` and `DELETE` using a hidden input field. ### params Params that were parsed from the URL. ### request The original request that was dispatched to the router. Note: Various properties of the original request may not be available or may have been modified by middleware. For example, the request's body may already have been consumed by the `formData` middleware (available as `context.get(FormData)`), or its method may have been overridden by the `methodOverride` middleware (available as `context.method`). You should default to using properties of the `context` object instead of the original request. However, the original request is made available in case you need it for some edge case. ### url The URL of the current request. ## Accessors ### router The router handling this request. ## Methods ### get(key: key): ResolveContextEntryValue Get a value from request context. #### key ### has(key: key): boolean Check whether a value exists in request context. #### key ### set(key: key, value: ContextValue): void Set a value in request context. #### key #### value The value to write
