Tips for resolving the issue when Chrome is able to load the page but Postman cannot find it

I'm encountering a perplexing situation that is entirely new to me and difficult to comprehend. I find myself unable to decipher what exactly I am witnessing, leading to uncertainty about why it is occurring, not to mention the challenge of determining how to resolve it.

Within my angular application, I have implemented a route as follows:

const routes: Routes = [
  { path: "beep", component: BeepComponent },
  { path: "**", component: LandingComponent }
];

The baffling aspect arises when accessing it through the browser (localhost:4200/beep) results in proper rendering. However, attempting the same request in Postman yields an unexpected outcome shown below.

<!DOCTYPE html>
<html lang="en><
  <head>
    <meta charset="utf-8">
    <title>Error</title>
  </head>
<body>
  <pre>Cannot GET /beep</pre>
</body>
</html>

What might this behavior signify? If unclear, how can I delve deeper into troubleshooting this issue? (The fact that such a scenario occurs has caught me off guard...)

Furthermore, upon running the page on Azure, a momentary 404 error appears before vanishing. This peculiar sequence seems to indicate the initial call fails (Not Found) followed by another request initiating (clearing the Network tab). Although I suspect resolving the Postman query will remedy this, for now, I am concentrating my efforts there.

Answer №1

When using a browser, the main purpose is to render and display HTML pages. On the other hand, Postman is designed for sending and receiving data through HTTP requests to specific service endpoints. This explains why your browser can successfully call a link while Postman may fail in doing so.

It's important to note that an Angular Component is not the same as an HTTP Service. Since the Component is not equipped to handle HTTP Requests, Postman doesn't receive a response and triggers an error message.
