Handling 403 Response in TypeScript and PHP by Showing UI Message and Suppressing Console

Handling 403 Response in TypeScript and PHP by Showing UI Message and Suppressing Console

When working with TypeScript and PHP, it is common to encounter a 403 response from the server when trying to access a resource that requires authentication or authorization. In such cases, it is important to handle the 403 response gracefully by showing a user-friendly message on the UI and suppressing any error messages in the console. In this blog post, we will explore two solutions to achieve this.

Solution 1: Using Fetch API and Promises

The Fetch API provides a modern way to make HTTP requests in JavaScript and TypeScript. We can use it to handle the 403 response and display a UI message. Here’s an example code snippet:

fetch('https://api.example.com/resource', {
  method: 'GET',
})
.then(response => {
  if (response.status === 403) {
    // Show UI message
    const errorMessage = document.createElement('p');
    errorMessage.textContent = 'You are not authorized to access this resource.';
    document.body.appendChild(errorMessage);
  } else {
    // Handle other responses
    // ...
  }
})
.catch(error => {
  console.error(error);
});

In this code snippet, we make a GET request to the resource using the Fetch API. If the response status is 403, we create a new paragraph element with the error message and append it to the body of the document. This will display the message on the UI. For other response statuses, you can add additional logic as needed.

Solution 2: Using XMLHttpRequest and Error Handling

If you prefer to use XMLHttpRequest instead of the Fetch API, you can achieve the same result by handling the 403 response in the error event. Here’s an example code snippet:

const xhr = new XMLHttpRequest();
xhr.open('GET', 'https://api.example.com/resource');
xhr.onload = function() {
  if (xhr.status === 403) {
    // Show UI message
    const errorMessage = document.createElement('p');
    errorMessage.textContent = 'You are not authorized to access this resource.';
    document.body.appendChild(errorMessage);
  } else {
    // Handle other responses
    // ...
  }
};
xhr.onerror = function() {
  console.error('An error occurred.');
};
xhr.send();

In this code snippet, we create a new XMLHttpRequest object and make a GET request to the resource. In the onload event handler, we check if the status is 403 and display the error message on the UI. For other response statuses, you can add additional logic. The onerror event handler is used to handle any network errors that may occur during the request.

By using either of these solutions, you can handle the 403 response in TypeScript and PHP by showing a user-friendly message on the UI and suppressing console errors. Choose the solution that best fits your project requirements and coding style.
