Generate Signed URL in S3 using boto3

Question

In Boto, I used to generate a signed URL using the below function.

import boto
conn = boto.connect_s3()
bucket = conn.get_bucket(bucket_name, validate=True)
key = bucket.get_key(key)
signed_url = key.generate_url(expires_in=3600)

How do I do the exact same thing in boto3?
I searched through boto3 GitHub codebase but could not find a single reference to generate_url.
Has the function name changed?

From Generating Presigned URLs:

import boto3
import requests

# Get the service client.
s3 = boto3.client('s3')

# Generate the URL to get 'key-name' from 'bucket-name'
url = s3.generate_presigned_url(
    ClientMethod='get_object',
    Params={
        'Bucket': 'bucket-name',
        'Key': 'key-name'
    }
)

# Use the URL to perform the GET operation. You can use any method you like
# to send the GET, but we will use requests here to keep things simple.
response = requests.get(url)
