# gcf-cors-anywhere

An alternative to [Rob--W/cors-anywhere](https://github.com/Rob--W/cors-anywhere).

gcf-cors-anywhere is a Node.js proxy which adds CORS headers to the proxied request running on Google Cloud Functions.

The url to proxy is taken from the search params `?u=`, validated and proxied.

## Deploy to your GCP project

[Tutorial](https://cloud.google.com/functions/docs/quickstart)

1. In the Google Cloud Console, on the project selector page, select or create a Google Cloud project.

2. Make sure that billing is enabled for your Cloud project. [Learn how to confirm that billing is enabled for your project.](https://cloud.google.com/billing/docs/how-to/modify-project)

3. Enable the Cloud Functions and Cloud Build APIs.

4. [Install and initialize the Cloud SDK.](https://cloud.google.com/sdk/docs?hl=zh-tw)

5. Update gcloud components:

    ```bash

    gcloud components update

    gcloud init

    ```

6. Deploy this function. YOU NEED TO CHANGE `PROJECT_ID` AND `GCP_REGION`.

    ```bash

    wget https://github.com/taichunmin/gcf-cors-anywhere/archive/master.zip -O gcf-cors-anywhere.zip

    unzip gcf-cors-anywhere.zip

    # YOU NEED TO CHANGE `PROJECT_ID` AND `GCP_REGION`.

    gcloud functions deploy cors-anywhere --allow-unauthenticated --entry-point=main --gen2 --max-instances=1 --memory=128Mi --no-user-output-enabled --project=PROJECT_ID --region=GCP_REGION --runtime=nodejs18 --timeout=60s --trigger-http --source ./gcf-cors-anywhere-master

    # clean up

    # rm -rf ./gcf-cors-anywhere.zip ./gcf-cors-anywhere-master

    ```

## Usage

Use Axios and LINE Login API as example:

### GET

```js

// YOU NEED TO CHANGE `PROJECT_ID` AND `GCP_REGION`.

const result = await axios.get('https://GCP_REGION-PROJECT_ID.cloudfunctions.net/cors-anywhere', {

  params: {

    u: 'https://api.line.me/v2/profile', // your real url

    // you can add additional params here

  },

  headers: { Authorization: 'Bearer ACCESS_TOKEN' },

})

console.log(result.data)

```

### POST

```js

// YOU NEED TO CHANGE `PROJECT_ID` AND `GCP_REGION`.

const result = await axios.post('https://GCP_REGION-PROJECT_ID.cloudfunctions.net/cors-anywhere', Qs.stringify({

  client_id: 'CLIENT_ID',

  id_token: 'ID_TOKEN',

  nonce: 'NONCE',

  user_id: 'USER_ID',

}), {

  params: { u: 'https://api.line.me/oauth2/v2.1/verify' }, // your real url

})

console.log(result.data)
