Initial Checks

• I confirm that I'm using Pydantic V2

Description

Using Pydantic 2.7.1 HttpUrl accepts URLs without TLDs.

From the Pydantic code comment:
A type that will accept any http or https URL.

• TLD required
• Host required
• Max length 2083

Example Code

>>>> from pydantic import BaseModel, HttpUrl, ValidationError
>>>> class MyModel(BaseModel):
...      url: HttpUrl
...
>>>> m = MyModel(url="http://www.example")
>>>> print(m.url)
http://www.example/

@Tom-Camp,

Thanks for reporting this. I think this is more of a docs bug, as we defer to the URL Rust Crate for URL validity decisions. I've added this to the current milestone as a docs issue.

Just as a side note, we'd recommend using a custom validator if you need to enforce the presence of a TLD!
