Emilien Chauvet	c3d4126eb1	community[minor]: add user agent for web scraping loaders (#22480) ... **Description:** This PR adds a `USER_AGENT` env variable that is to be used for web scraping. It creates a util to get that user agent and uses it in the classes used for scraping in [this piece of doc](https://python.langchain.com/v0.1/docs/use_cases/web_scraping/). Identifying your scraper is considered a good politeness practice, this PR aims at easing it. **Issue:** `None` **Dependencies:** `None` **Twitter handle:** `None`	4 months ago
Kefan You	24b5c27bb1	community[patch]: raise_for_status logic missing in async _fetch of WebBaseLoader (#21948) ... ## 'raise_for_status' parameter of WebBaseLoader works in sync load but not in async load. In webBaseLoader: Sync load is calling `_scrape` and has `raise_for_status` properly handled. ``` def _scrape( self, url: str, parser: Union[str, None] = None, bs_kwargs: Optional[dict] = None, ) -> Any: from bs4 import BeautifulSoup if parser is None: if url.endswith(".xml"): parser = "xml" else: parser = self.default_parser self._check_parser(parser) html_doc = self.session.get(url, **self.requests_kwargs) if self.raise_for_status: html_doc.raise_for_status() if self.encoding is not None: html_doc.encoding = self.encoding elif self.autoset_encoding: html_doc.encoding = html_doc.apparent_encoding return BeautifulSoup(html_doc.text, parser, **(bs_kwargs or {})) ``` Async load is calling `_fetch` but missing `raise_for_status` logic. ``` async def _fetch( self, url: str, retries: int = 3, cooldown: int = 2, backoff: float = 1.5 ) -> str: async with aiohttp.ClientSession() as session: for i in range(retries): try: async with session.get( url, headers=self.session.headers, ssl=None if self.session.verify else False, cookies=self.session.cookies.get_dict(), ) as response: return await response.text() ``` Co-authored-by: kefan.you <darkfss@sina.com>	4 months ago

João Carlos Ferra de Almeida	3e87b67a3c	community[patch]: Add Cookie Support to Fetch Method (#16673) ... - **Description:** This change allows the `_fetch` method in the `WebBaseLoader` class to utilize cookies from an existing `requests.Session`. It ensures that when the `fetch` method is used, any cookies in the provided session are included in the request. This enhancement maintains compatibility with existing functionality while extending the utility of the `fetch` method for scenarios where cookie persistence is necessary. - **Issue:** Not applicable (new feature), - **Dependencies:** Requires `aiohttp` and `requests` libraries (no new dependencies introduced), - **Twitter handle:** N/A Co-authored-by: Joao Almeida <joao.almeida@mercedes-benz.io>	8 months ago
