Recently, I have been working on a task, regarding AWS S3 bucket file uploading using Angular and preSigned URLs. In that project, I have used HTTP interceptor to handle my request to bind all header parameters. My problem arose while I was trying upload files and found that I wasn’t able to since there were “two Authorization headers” in that request. They were the usual request header with token and the header which auto binds by the presigned Url. To solve this issue, I found a super-easy solution that allowed me to bypass my HTTP interceptor and BOOM! Issue fixed. Let’s dive into what I did.
Before starting the explanation of my trick, let’s get to know what interceptors are and how we can use them.
As I mentioned above, there are occasions where we need to allow for a custom header (or, in other words, to skip the interceptor action in http requests).
BONUS POINT:_ Usually in Angular best practices, it is better to keep our services separate from modules, components and models etc. Please checkout the below folder structure. It is better if you can refer to this structure for your future implementations._
src ┣ app ┃ ┣ common ┃ ┣ customer ┃ ┣ models ┃ ┣ public ┃ ┣ services ┃ ┃ ┣ authentication ┃ ┃ ┃ ┣ guards ┃ ┃ ┃ ┃ ┣ auth.guard.ts ┃ ┃ ┃ ┣ interceptors ┃ ┃ ┃ ┃ ┣ response.interceptor.ts ┃ ┃ ┃ ┗ auth.service.ts ┃ ┃ ┣ directives ┃ ┃ ┣ pipes ┃ ┃ ┣ resolvers ┃ ┃ ┣ services-api ┃ ┃ ┣ services-inter ┃ ┣ app.component.css ┃ ┣ app.component.html ┃ ┣ app.component.spec.ts ┃ ┣ app.component.ts ┃ ┣ app.module.ts ┃ ┣ app.routing.ts ┃ ┗ app.server.module.ts ┣ assets ┣ environments ┣ favicon.ico ┣ index.html
As per the file tree, I kept my interceptors inside the _src/services/interceptors _folder.

Angular has great built-in tools for making web requests. It also contains a great module for testing HTTP communication: HttpClientTestingModule. This module contains full toolbox to ensure web communication happens as intended by the developer.
This step by step guide helps you ascertain the usage, implementation, on top of that, the benefits of HttpClient API in the Angular 11 application. It also enables you to answer how to make HTTP (HTTP POST, GET, PUT, and DELETE) Requests. How to Make HTTP Requests with Angular 11 HttpClient API
Dealing with API based token is sometimes cumbersome. Due to the fact that, on every request, we have to send a token as parameter to be able to reach out the server. In Angular, it becomes easier with the help of HttpClient interceptors. In this…
Angular HttpClient is inbuilt module that helps us to send network requests to any server. Angular HttpClientModule is used to send GET, POST request.
