Servant.API

Synopsis

Combinators

data (path :: k) :> (a :: *) infixr 4 Source #

The contained API (second argument) can be found under ("/" ++ path) (path being the first argument).

Example:

>>> -- GET /hello/world
>>> -- returning a JSON encoded World value
>>> type MyApi = "hello" :> "world" :> Get '[JSON] World

type QueryParam = QueryParam' '[Optional, Strict] Source #

Lookup the value associated to the sym query string parameter and try to extract it as a value of type a.

Example:

>>> -- /books?author=<author name>
>>> type MyApi = "books" :> QueryParam "author" Text :> Get '[JSON] [Book]

data QueryFlag (sym :: Symbol) Source #

Lookup a potentially value-less query string parameter with boolean semantics. If the param sym is there without any value, or if it's there with value "true" or "1", it's interpreted as True. Otherwise, it's interpreted as False.

Example:

>>> -- /books?published
>>> type MyApi = "books" :> QueryFlag "published" :> Get '[JSON] [Book]

data QueryParams (sym :: Symbol) (a :: *) Source #

Lookup the values associated to the sym query string parameter and try to extract it as a value of type [a]. This is typically meant to support query string parameters of the form param[]=val1&param[]=val2 and so on. Note that servant doesn't actually require the []s and will fetch the values just fine with param=val1&param=val2, too.

Example:

>>> -- /books?authors[]=<author1>&authors[]=<author2>&...
>>> type MyApi = "books" :> QueryParams "authors" Text :> Get '[JSON] [Book]

Retrieving the IP of the client

data IsSecure Source #

Was this request made over an SSL connection?

Note that this value will not tell you if the client originally made this request over SSL, but rather whether the current connection is SSL. The distinction lies with reverse proxies. In many cases, the client will connect to a load balancer over SSL, but connect to the WAI handler without SSL. In such a case, the handlers would get NotSecure, but from a user perspective, there is a secure connection.

data UVerb (method :: StdMethod) (contentTypes :: [*]) (as :: [*]) Source #

A variant of Verb that can have any of a number of response values and status codes.

FUTUREWORK: it would be nice to make Verb a special case of UVerb, and only write instances for HasServer etc. for the latter, getting them for the former for free. Something like:

type Verb method statusCode contentTypes a = UVerb method contentTypes [WithStatus statusCode a]

Backwards compatibility is tricky, though: this type alias would mean people would have to use respond instead of pure or return, so all old handlers would have to be rewritten.

data NetstringFraming Source #

The netstring framing strategy as defined by djb: http://cr.yp.to/proto/netstrings.txt

Any string of 8-bit bytes may be encoded as [len]":"[string]",". Here [string] is the string and [len] is a nonempty sequence of ASCII digits giving the length of [string] in decimal. The ASCII digits are 30 for 0, 31 for 1, and so on up through 39 for 9. Extra zeros at the front of [len] are prohibited: [len] begins with 30 exactly when [string] is empty.

For example, the string "hello world!" is encoded as 32 3a 68 65 6c 6c 6f 20 77 6f 72 6c 64 21 2c, i.e., "12:hello world!,". The empty string is encoded as "0:,".

Authentication

data BasicAuth (realm :: Symbol) (userData :: *) Source #

Combinator for Basic Access Authentication.

  • IMPORTANT*: Only use Basic Auth over HTTPS! Credentials are not hashed or encrypted. Note also that because the same credentials are sent on every request, Basic Auth is not as secure as some alternatives. Further, the implementation in servant-server does not protect against some types of timing attacks.

In Basic Auth, username and password are base64-encoded and transmitted via the Authorization header. Handshakes are not required, making it relatively efficient.

addHeader :: AddHeader h v orig new => v -> orig -> new Source #

addHeader adds a header to a response. Note that it changes the type of the value in the following ways:

  1. A simple value is wrapped in "Headers '[hdr]":
>>> let example0 = addHeader 5 "hi" :: Headers '[Header "someheader" Int] String;
>>> getHeaders example0
[("someheader","5")]
  1. A value that already has a header has its new header *prepended* to the existing list:
>>> let example1 = addHeader 5 "hi" :: Headers '[Header "someheader" Int] String;
>>> let example2 = addHeader True example1 :: Headers '[Header "1st" Bool, Header "someheader" Int] String
>>> getHeaders example2
[("1st","true"),("someheader","5")]

Note that while in your handlers type annotations are not required, since the type can be inferred from the API type, in other cases you may find yourself needing to add annotations.

lookupResponseHeader :: HasResponseHeader h a headers => Headers headers r -> ResponseHeader h a Source #

Look up a specific ResponseHeader, without having to know what position it is in the HList.

>>> let example1 = addHeader 5 "hi" :: Headers '[Header "someheader" Int] String
>>> let example2 = addHeader True example1 :: Headers '[Header "1st" Bool, Header "someheader" Int] String
>>> lookupResponseHeader example2 :: ResponseHeader "someheader" Int
Header 5
>>> lookupResponseHeader example2 :: ResponseHeader "1st" Bool
Header True

Usage of this function relies on an explicit type annotation of the header to be looked up. This can be done with type annotations on the result, or with an explicit type application. In this example, the type of header value is determined by the type-inference, we only specify the name of the header:

>>> :set -XTypeApplications
>>> case lookupResponseHeader @"1st" example2 of { Header b -> b ; _ -> False }
True

Since: 0.15

noHeader :: AddHeader h v orig new => orig -> new Source #

Deliberately do not add a header to a value.

>>> let example1 = noHeader "hi" :: Headers '[Header "someheader" Int] String
>>> getHeaders example1
[]

Untyped endpoints

data Raw Source #

Endpoint for plugging in your own Wai Applications.

The given Application will get the request as received by the server, potentially with a modified (stripped) pathInfo if the Application is being routed with :>.

In addition to just letting you plug in your existing WAI Applications, this can also be used with functions from Servant.Server.StaticFiles to serve static files stored in a particular directory on your filesystem

class HasLink endpoint where Source #

Construct a toLink for an endpoint.

Associated Types

type MkLink endpoint (a :: *) Source #

Methods

toLink Source #

Arguments

:: (Link -> a) 
-> Proxy endpoint

The API endpoint you would like to point to

-> Link 
-> MkLink endpoint a 

Instances

type family IsElem endpoint api :: Constraint where ... Source #

Closed type family, check if endpoint is within api. Uses IsElem' if it exhausts all other options.

>>> ok (Proxy :: Proxy (IsElem ("hello" :> Get '[JSON] Int) SampleAPI))
OK
>>> ok (Proxy :: Proxy (IsElem ("bye" :> Get '[JSON] Int) SampleAPI))
...
... Could not ...
...

An endpoint is considered within an api even if it is missing combinators that don't affect the URL:

>>> ok (Proxy :: Proxy (IsElem (Get '[JSON] Int) (Header "h" Bool :> Get '[JSON] Int)))
OK
>>> ok (Proxy :: Proxy (IsElem (Get '[JSON] Int) (ReqBody '[JSON] Bool :> Get '[JSON] Int)))
OK
  • N.B.:* IsElem a b can be seen as capturing the notion of whether the URL represented by a would match the URL represented by b, *not* whether a request represented by a matches the endpoints serving b (for the latter, use IsIn).

Equations

IsElem e (sa :<|> sb) = Or (IsElem e sa) (IsElem e sb) 
IsElem (e :> sa) (e :> sb) = IsElem sa sb 
IsElem sa (Header sym x :> sb) = IsElem sa sb 
IsElem sa (ReqBody y x :> sb) = IsElem sa sb 
IsElem (CaptureAll z y :> sa) (CaptureAll x y :> sb) = IsElem sa sb 
IsElem (Capture z y :> sa) (Capture x y :> sb) = IsElem sa sb 
IsElem sa (QueryParam x y :> sb) = IsElem sa sb 
IsElem sa (QueryParams x y :> sb) = IsElem sa sb 
IsElem sa (QueryFlag x :> sb) = IsElem sa sb 
IsElem sa (Fragment x :> sb) = IsElem sa sb 
IsElem (Verb m s ct typ) (Verb m s ct' typ) = IsSubList ct ct' 
IsElem e e = () 
IsElem e a = IsElem' e a 

type family IsElem' a s :: Constraint Source #

You may use this type family to tell the type checker that your custom type may be skipped as part of a link. This is useful for things like QueryParam that are optional in a URI and do not affect them if they are omitted.

>>> data CustomThing
>>> type instance IsElem' e (CustomThing :> s) = IsElem e s

Note that IsElem is called, which will mutually recurse back to IsElem' if it exhausts all other options again.

Once you have written a HasLink instance for CustomThing you are ready to go.

data Link Source #
