Prohibit the utilization of application/json in a single request

Below is the code I have written to send a request for uploading a file:

 const uploadReq = new HttpRequest('POST', "https://localhost:44372/api/v1/Upload/UploadNewsPic"
  , formData, { reportProgress: true });
  this.http.request(uploadReq).subscribe(event => {
    if (event.type === HttpEventType.UploadProgress)
      this.progress = Math.round(100 * event.loaded / event.total);
    else if (event.type === HttpEventType.Response)
      this.message = event.body.toString();
  })

I am also using an interceptor to automatically add 'application/json' as a header, but I do not want this header to be added for this specific request.

How can I achieve this?

Answer №1

In situations where you have access to an interceptor, it is possible to inspect the URL and determine whether to include a specific header for a given request:

@Injectable()
export class ModifyHttpHeaderService implements HttpInterceptor {
  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const url = request.url;

    if (url === 'https://example.com/api/v1/endpoint') {
      return next.handle(request);
    }

    // Implement other logic in the interceptor for modifying headers
    ...
