I got recommended in another thread that I should use ServiceClient when using a ServiceStack API.
I would like to create a template function that can post any type of objects like this:
public Post2<T>(object: T, url: string, httpOptions)
{
try
{
var client = new JsonServiceClient(`${environment.apiEndpoint}` + url)
client.headers = httpOptions;
client.post<T>(object);
}
catch(e)
{
}
}
The problem is that it tells me that "argument of type T is not assignable to parameter of type IReturn.
typescript-ref http://techstacks.io generated the following DTO's (for this purpose)
// @Route("/Equipments", "POST")
export class CreateEquipment
{
public name: string;
}
// @Route("/Equipments/{Name}", "GET")
export class GetEquipment implements IReturn<Equipment>
{
public name: string;
public createResponse() { return new Equipment(); }
public getTypeName() { return 'GetEquipment'; }
}
// @Route("/Equipments", "GET")
export class GetEquipments implements IReturn<Equipment[]>
{
public createResponse() { return new Array<Equipment>(); }
public getTypeName() { return 'GetEquipments'; }
}
// @Route("/Equipments/{Name}", "DELETE")
export class DeleteEquipment
{
public name: string;
}
I tried to use the following code to create the Post request.
var request = new CreateEquipment();
request.name = equipment.name;
var client = new JsonServiceClient(environment.apiEndpoint);
var response = await client.post(request);
This gives an error in the VS17; argument of type 'CreateEquipment' is not assignable to parameter of type 'IReturn<{}>'.Property createResponse is missing in type'CreateEquipment'
Which I presume means that I am missing something in my ServiceModel
ServiceStack's TypeScript Service Client should only be constructed with the BaseUrl for where your ServiceStack Host is located, or if you don't specify an argument it will use /
by default:
var client = new JsonServiceClient(environment.apiEndpoint);
You also need to use it with the TypeScript generated DTOs from your ServiceStack Service which you can generate by installing the @servicestack\cli
npm util:
$ npm install -g @servicestack/cli
Then using it to generate your Server DTOs from the BaseUrl (should be the same as environment.apiEndpoint):
$ typescript-ref http://example.org
Then you can use it to send populated Request DTOs:
var request = new MyRequest();
var response = await client.post(request);
Note your ServiceStack Services should be annotated with the IReturn<T>
(or IReturnVoid) interface marker specifying the Services Response DTO.
You can also make API Requests using URLs, but you'll need to specify the Response DTO Type it returns, e.g:
client.get<GetTechnologyResponse>("/technology", { Slug: "ServiceStack" })
