I have a JSON hosted somewhere and I want to fetch the content, put it in a context for my leaf template to read.
However, I cannot make it work. I get the code to compile, but I get an error in the localhost
{"error":true,"reason":"Unsupported Media Type"}
Can somebody help me please. Happy holidays for all.
struct WebsiteController: RouteCollection {
func boot(routes: RoutesBuilder) throws {
routes.get(use: indexHandler)
}
func indexHandler(_ req: Request) -> EventLoopFuture<View> {
return req.client.get("https://streeteasydaily.s3.us-west-2.amazonaws.com/streeteasy1.json").flatMap { res in
do {
let json = try res.content.decode([Listing].self)
print(json[0].photos[0])
let context = IndexContext(title: "Homepage", listings: json)
return try req.view.render("index", context)
} catch {
// Handle error
print("cayo en error")
return req.eventLoop.makeFailedFuture(error)
}
}
}
}
struct IndexContext: Encodable {
let title: String
let listings: [Listing]
}
Model
final class Listing: Model {
static let schema = "listings" //basically the table name
@ID
var id: UUID?
@Field(key: "address")
var address: String
@Field(key: "description")
var description: String
@Field(key: "photos")
var photos: [String]
init() {}
//to initialize the db
init(id: UUID? = nil, address: String, description: String, photos: [String]) {
self.id = id
self.address = address
self.description = description
self.photos = photos
}
}
//to make acronym conform to CONTENT, and use it in Vapor
extension Listing: Content {}
This error is because the decode is failing to identify all the fields in your JSON to match against those defined in Listing
and/or the array of such objects. The filenames must match those in the JSON exactly - ie case-sensitive and every field in the structure/model must exist in the JSON. Additional fields in the JSON that are not needed/included in the structure/model are fine.
