# class: Route

Whenever a network route is set up with [`method: Page.route`] or [`method: BrowserContext.route`], the `Route` object
allows to handle the route.

## async method: Route.abort

Aborts the route's request.

### param: Route.abort.errorCode
- `errorCode` <[string]>

Optional error code. Defaults to `failed`, could be one of the following:
* `'aborted'` - An operation was aborted (due to user action)
* `'accessdenied'` - Permission to access a resource, other than the network, was denied
* `'addressunreachable'` - The IP address is unreachable. This usually means that there is no route to the specified
  host or network.
* `'blockedbyclient'` - The client chose to block the request.
* `'blockedbyresponse'` - The request failed because the response was delivered along with requirements which are not
  met ('X-Frame-Options' and 'Content-Security-Policy' ancestor checks, for instance).
* `'connectionaborted'` - A connection timed out as a result of not receiving an ACK for data sent.
* `'connectionclosed'` - A connection was closed (corresponding to a TCP FIN).
* `'connectionfailed'` - A connection attempt failed.
* `'connectionrefused'` - A connection attempt was refused.
* `'connectionreset'` - A connection was reset (corresponding to a TCP RST).
* `'internetdisconnected'` - The Internet connection has been lost.
* `'namenotresolved'` - The host name could not be resolved.
* `'timedout'` - An operation timed out.
* `'failed'` - A generic failure occurred.

## async method: Route.continue
* langs:
  - alias-python: continue_

Continues route's request with optional overrides.

```js
await page.route('**/*', (route, request) => {
  // Override headers
  const headers = {
    ...request.headers(),
    foo: 'bar', // set "foo" header
    origin: undefined, // remove "origin" header
  };
  route.continue({headers});
});
```

```python async
async def handle(route, request):
    # override headers
    headers = {
        **request.headers,
        "foo": "bar" # set "foo" header
        "origin": None # remove "origin" header
    }
    await route.continue(headers=headers)
}
await page.route("**/*", handle)
```

```python sync
def handle(route, request):
    # override headers
    headers = {
        **request.headers,
        "foo": "bar" # set "foo" header
        "origin": None # remove "origin" header
    }
    route.continue(headers=headers)
}
page.route("**/*", handle)
```

### option: Route.continue.url
- `url` <[string]>

If set changes the request URL. New URL must have same protocol as original one.

### option: Route.continue.method
- `method` <[string]>

If set changes the request method (e.g. GET or POST)

### option: Route.continue.postData
- `postData` <[string]|[Buffer]>

If set changes the post data of request

### option: Route.continue.headers
- `headers` <[Object]<[string], [string]>>

If set changes the request HTTP headers. Header values will be converted to a string.

## async method: Route.fulfill

Fulfills route's request with given response.

An example of fulfilling all requests with 404 responses:

```js
await page.route('**/*', route => {
  route.fulfill({
    status: 404,
    contentType: 'text/plain',
    body: 'Not Found!'
  });
});
```

```python async
await page.route("**/*", lambda route: route.fulfill(
    status=404,
    content_type="text/plain",
    body="not found!"))
```

```python sync
page.route("**/*", lambda route: route.fulfill(
    status=404,
    content_type="text/plain",
    body="not found!"))
```

An example of serving static file:

```js
await page.route('**/xhr_endpoint', route => route.fulfill({ path: 'mock_data.json' }));
```

```python async
await page.route("**/xhr_endpoint", lambda route: route.fulfill(path="mock_data.json"))
```

```python sync
page.route("**/xhr_endpoint", lambda route: route.fulfill(path="mock_data.json"))
```

### option: Route.fulfill.status
- `status` <[int]>

Response status code, defaults to `200`.

### option: Route.fulfill.headers
- `headers` <[Object]<[string], [string]>>

Response headers. Header values will be converted to a string.

### option: Route.fulfill.contentType
- `contentType` <[string]>

If set, equals to setting `Content-Type` response header.

### option: Route.fulfill.body
- `body` <[string]|[Buffer]>

Response body.

### option: Route.fulfill.path
- `path` <[path]>

File path to respond with. The content type will be inferred from file extension. If `path` is a relative path, then it
is resolved relative to the current working directory.

## method: Route.request
- returns: <[Request]>

A request to be routed.
