Tasks

Implement the following four URLs:

/text

This URL should accept a query string of the form:
```
?content=Your text goes here
```
The value provided under content key of the query string should be encoded in a QR code as plain text.
/url

This URL should accept a query string of the form:
```
?page=https://www.wikipedia.org
```
The value provided under the page key of the query string should be encoded in a QR code as a URL (which is just plain text that begins with http or https).
/wifi

This URL should accept a query string of the form:
```
?ssid=Your network name&pw=secret password
```
The values provided under the ssid and pw keys should be encoded in a QR code as a wifi network. For example:
```
WIFI:T:WPA;S:Your network name;P:secret password;;
```
/sms

This URL should accept a query string of the form:
```
?phone=9876543210&message=Hi Alice! It's me,
```
The values provided under the phone and message keys should be encoded in a QR code as a text message: For example:
```
SMSTO:9876543210:Hi Alice! It's me, 
```
