How can i decode the following json-array (which is part of a http-request)



[ 
"id": 0, "name": "darth maul" ,
"id": 1, "name": "darth sidious"
]


in swift vapor 3 with the decode function?



vapor code:



struct User: Content 
var id: Int
var name: String


router.put("user") request -> Future<HTTPStatus> in
return try request.content.decode(User.self).map( (user) -> (HTTPStatus) in
// process ...
return .ok
)

  • No, I mean the client (e.g. an iphone) send a http request to the server (implemented with vapor). The server defines the route "user" and must use a decode function.

Your code is pretty close already, only a tiny change is needed: instead of decoding a single User, decode an array of them. Note the square brackets in decode.



router.put("user") request -> Future<HTTPStatus> in
return try request.content.decode([User].self).map( (users) -> (HTTPStatus) in
// process ...
return .ok
)

  • Your answer was useful and the request-decoding works! But when i am starting the vapor service, the following error occurs: DecodingError.typeMismatch: Value of type 'Array<Any>' required for key ''. (ErrorMiddleware.swift:26). Can you help?
