error with authorization header angular http-CodePudding

i have backend in node js expree and sequelize im trying to get all my product_types when y made the peticion with postman to my backend this is the answer:

postman http request and header

but when i make the same peticion on my frontend angular i got a error

header Authorization is missing

this is my angular services http request

 getTypes(token:any):Observable<any>{
    let headers = new HttpHeaders().set('Content-Type', 'application/json')
                                   .set('Authorization', token);
    console.log(headers)
    return this._http.post(this.url   'productType/getall', {headers:headers});
    
  }

this is the header that goes to my postman backend

CodePudding user response：

Your HttpClient post params are not in the correct order..

post(url: string, body: any, options: { headers?: HttpHeaders....

The 2nd param is the body of the post, 3rd is the options with headers

Or, maybe you should be using get - in which case you'd keep your params as is
