response( [status], body, [headers], [statusText] )

Using the response function to return an unauthorized error.

import {fixture, ajax} from "can";

fixture( {url: "/todos/{action}"},
  ( request, response, headers, ajaxSettings ) => {
    response(
      401,
      { message: "Unauthorized" },
      { "WWW-Authenticate": "Basic realm=\"myRealm\"" },
      "unauthorized"
    );
  }
);

// fixture response log {
//   headers: {WWW-Authenticate: "Basic realm='myRealm'"},
//   responseBody: {message: "Unauthorized"},
//   statusCode: 401,
//   statusText: "unauthorized"
// }

ajax( {type:"POST", url: "/todos/delete"} ).catch( error => {
  console.log(error); //-> {message: "Unauthorized"}
} );

The default statusText will be "ok" for statuses between 200 and 300 including 200, and 304. It will "error" for everything else.

response( body )

Using the body object to return a single message. The status will be 200 and statusText will be "ok".

import {fixture, ajax} from "can";

fixture( {url: "/todos"}, ( request, response ) => {
  // Just body
  response( { message: "Hello World" } );
});

ajax( {url: "/todos"} ).then( result => {
  console.log( result ); //-> {message: "Hello World"}
} );

response( [status], body )

Response will always return a 401 status. The statusText will be "error".

import {fixture, ajax} from "can";

fixture( {url: "/todos"}, ( request, response ) => {
  // status and body
  response( 401, { message: "Unauthorized" } );
});

ajax( {url:"/todos"} ).catch( error => {
  console.log( error ); //-> 401, {message: "Unauthorized"}
});

response( body, [headers] )

Response will return the responseBody with custom headers. Because it's not set the status will default to 200, and the statusText to "ok".

import {fixture, ajax} from "can";

fixture( {url: "/todos"}, ( request, response ) => {
  // body and headers
  response(
    "{\"message\":\"Unauthorized\"}",
    { "WWW-Authenticate": "Basic realm=\"myRealm\"" }
  );
});

ajax( {url: "/todos"} ).then( result => {
  console.log( result ); //-> {message: "Unauthorized"}
} );

response( [status], body, [statusText] )

Response will return with the given status and statusText along with the responseBody.

import {fixture, ajax} from "can";

fixture( {url: "/todos"}, ( request, response ) => {
  // status, body, statusText
  response( 401, "{\"message\":\"Unauthorized\"}", "unauthorized" );
});

ajax( {url: "/todos"} ).catch( error => {
  console.log(error); //-> {message: "Unauthorized"}
} );
