Hi
I am using loopback 4 for backend and react for front end.
when I make a request on API, it gives me blocked Cors.
I tried this :
let config = {
mode: 'cors',
cache: 'no-cache',
credentials: 'same-origin',
headers: {
'Access-Control-Allow-Origin': '*',
'Content-Type': 'application/json',
},
redirect: 'follow',
referrerPolicy: 'no-referrer',
}
const response = await axios.post(${API}/signUppatient, obj, config);
but it didn't work
const config = {
name: 'ipfs',
connector: 'rest',
baseURL: 'http://localhost:5001/api/v0/',
crud: false,
operations: [
{
template: {
method: 'POST',
url: 'http://localhost:5001/api/v0/add',
headers: {
'content-type': 'multipart/form-data;'
},
query: {
'only-hash': true,
},
form: {
file: '{file}',
},
},
functions: {
getCID: ['file'],
},
},
{
template: {
method: 'POST',
url: 'http://localhost:5001/api/v0/bootstrap/list',
},
functions: {
getPeers: [],
},
},
],
};export interface Ipfs {
getCID(file: Buffer): Promise<CID>,
getPeers(): Promise<unknown>

allowArray in an option somewhere. However, I have not found where this option should be inserted. In the model json description I assume, but where?

Hey Guys, slowly I'm getting frustrated, maybe you can help me out. My problem might be more of a TypeScript problem than a lb4 problem, but maybe you ran into this too.
I built a controller to download a file, like described here: https://loopback.io/doc/en/lb4/File-upload-download.html
Thus I'm injecting the response into my function. Now I'm trying to write a unit test for the controller and am trying to create a stubInstance for the response object which is expected by the function with sinon, but Typescript is not capable of create a stub for an interface. (Type 'SinonStubbedInstance<Response>' is missing the following properties from type 'Response<any, Record<string, any>>': sendStatus, links, send, jsonp, and 77 more.)
Long story short: Any ideas how to unit-test a controller with a injected response object?

i) Implement global interceptors for Authentication, authorization as global interceptors
ii) Controllers, services for CRUD operations on URI /data and apply authentication and authorization on this.
iii) Implement a local interceptor for a controller for particular URI say /forward to invoke middleware provided by node module http-proxy-middleware, to forward the requests to external URLs with headers and body.
Is this a good solution for this problem? What could be a better approach?
How to avoid authentication interceptors getting invoked for requests beling forwarded
Do we need to do any additional to avoid CORS issues as cors is the first middleware called in the sequence
app.use('/authentication', checkAuthentication)
app.use ('/authorization', checkAuthrorization)
app.use('/protectedResource', protectedResourceController)

Hi, I have created a model and trying to cast/validate the post req body. But, loopback is ignoring the model definition.
Model Definition :
import {Entity, model, property} from '@loopback/repository';
import {company, customer} from '../interfaces';
@model()
export class BulkCompany extends Entity {
@property({
type: 'number',
id: true,
generated: true,
})
id?: number;
@property({
type: 'object',
required: true,
})
company: company;
@property({
type: 'object',
required: true,
})
customer: customer;
constructor(data?: Partial<BulkCompany>) {
super(data);
}
}
export interface BulkCompanyRelations {
// describe navigational properties here
}
export type BulkCompanyWithRelations = BulkCompany & BulkCompanyRelations;
Interfaces :
export interface beneficialOwners {
name: string;
title: string;
ownershipPercentage: number;
}
export interface company {
name: string;
state: string;
type: string;
designator: string;
website: string;
description: string;
industry: string;
beneficialOwners: beneficialOwners[];
alternateName: string;
}
export interface customer {
email: string;
name: string;
phone: string;
addressLine1: string;
addressCity: string;
addressState: string;
addressZip: string;
}
Route :
async createBulkCompanies(
@requestBody({
content: {
'application/json': {
schema: {
type: 'array',
additionalProperties: false,
items: getModelSchemaRef(BulkCompany, {
title: 'BulkCompany',
exclude: ['id'],
}),
},
},
},
})
company: [Omit<BulkCompany, 'id'>],
): Promise<any> {}
Problem is i am not getting a validation on company.beneficialOwners
