Using Angular 6 to pass basic authentication in httpClient's httpOptions

I am currently working on an Angular 6 service where I am attempting to modify a record, but the system is indicating that I do not have authorization.

At this moment, my code looks like this:

const httpOptions = {
  headers: new HttpHeaders({'Content-Type': 'application/json'})
};

  update(id, title, content) {
    const updateData = { id: id, title: title, content: content };
      return this.http.put(`http://myurl/${id}`, updateData, httpOptions);
  }

Here is my query:

How can I implement basic authorization in my httpOptions or should I directly add it to the update method?

Answer №1

If you need to include basic authorization, you can do so by adding it to the headers like this:

let headersObject = new HttpHeaders();
headersObject.append('Content-Type', 'application/json');
headersObject.append("Authorization", "Basic " + btoa("username:password"));

const httpOptions = {
  headers: headersObject
};

After reviewing the angular.io documentation, it seems quite simple.

const httpOptions = {
  headers: new HttpHeaders({
    'Content-Type':  'application/json',
    'Authorization': 'Basic my-auth-token'
  })
};

You can utilize the httpOptions constant in the same way as demonstrated.

For further details: https://angular.io/guide/http#adding-headers

Note: While this approach works well for small or quick applications, for more robust apps, consider implementing an HTTP interceptor to automatically add the Authorization header dynamically.

Answer №3

To include your token or authorization in the headers, follow this code snippet:

const httpHeaders = new HttpHeaders()
              .set('authorization', this.authorizationHeaderValue)
              .set('Content-Type', 'application/json');

Both set and append methods are available. The set method creates a new body with a specified value, while the append method adds a value to the existing body.

Note: Make sure to adjust the value of the variable (this.authorizationHeaderValue) to match the required format such as Bearer or Basic.

Implementing basic authentication in httpOptions with httpClient has changed in Angular 6

let customHeaders = new HttpHeaders();
customHeaders.append('Content-Type', 'application/json');
customHeaders.append("Authorization", "Basic " + btoa("username:password"));

const httpRequestOptions = {
  headers: customHeaders
};

updateData = (id, title, content) => {
    const dataToUpdate = { id: id, title: title, content: content };
      return this.http.put(`http://exampleurl/${id}`, dataToUpdate, httpRequestOptions);
  }

To ensure safe operations, many servers require additional headers. For instance, a server may need an authorization token or a "Content-Type" header to specify the MIME type of the request body explicitly. In your situation, you can implement basic authorization using the following code:

import { HttpHeaders } from '@angular/common/http'; 
const httpOptions = {headers: new HttpHeaders({
'Content-Type':  'application/json',
Authorization: 'my-auth-token' })};

You can modify the authorization header before sending the next request:

httpOptions.headers =  httpOptions.headers.set('Authorization', 'my-new-auth-token');
