Google Place Api No Access Control Allow Origin Header Is Present On The Requested Resource Origin Null Is Therefore Not Allowed Access Duplicate

Have you ever encountered the error message "No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access" when working with the Google Places API in your web development projects? This issue can be a common stumbling block when trying to fetch data from the Google Places API using JavaScript. But fear not, as we have a solution to help you navigate and resolve this problem.

If you are developing a website or web application that interacts with the Google Places API, you might have faced this error because of the security restrictions imposed by the browser. This error occurs when the browser blocks requests made from a different domain (origin) than the one hosting the JavaScript code. The lack of the 'Access-Control-Allow-Origin' header in the response from the API server triggers this error.

To fix this issue and enable your application to access the Google Places API successfully, you need to set up a proxy server. A proxy server acts as an intermediary between your web application and the Google Places API server, allowing you to bypass the 'same-origin policy' enforced by browsers.

To set up a proxy server, you can use tools like CORS Anywhere or create your custom server-side script using Node.js, Python, PHP, or any other server-side technology you are comfortable with. Let's walk through a simple example using CORS Anywhere:

1. Go to the CORS Anywhere repository on GitHub (https://github.com/Rob--W/cors-anywhere/) and follow the instructions to deploy your instance of the proxy server.

2. Once your proxy server is up and running, modify your JavaScript code to make API requests through the proxy by appending the proxy server URL before the Google Places API endpoint. For example:

const proxyUrl = 'https://your-proxy-server-url/';
const apiUrl = 'https://maps.googleapis.com/maps/api/place/details/json?place_id=YOUR_PLACE_ID&amp;key=YOUR_API_KEY';

fetch(proxyUrl + apiUrl)
  .then(response =&gt; response.json())
  .then(data =&gt; console.log(data))
  .catch(error =&gt; console.log(error));

By sending your API requests through the proxy server, the necessary 'Access-Control-Allow-Origin' header will be included in the response, resolving the CORS issue and allowing your application to access the Google Places API data securely.

Remember to replace 'YOUR_PROXY_SERVER_URL,' 'YOUR_PLACE_ID,' and 'YOUR_API_KEY' placeholders with your actual server URL, Google Places API parameters, and API key, respectively.

In conclusion, handling the "No 'Access-Control-Allow-Origin' header" error when working with the Google Places API involves setting up a proxy server to bypass CORS restrictions imposed by browsers. By following the steps outlined above, you can ensure seamless communication between your web application and the Google Places API, enabling you to integrate location-based services effortlessly. Happy coding!
