| 1978022687 | I_kwDOBm6k_c515jsf | 2204 | request.post_body() can only be called once | 9599 | open | 0 | 0 | 2023-11-05T23:22:03Z | 2023-11-05T23:23:23Z | OWNER | This code here: https://github.com/simonw/datasette/blob/452a587e236ef642cbc6ae345b58767ea8420cb5/datasette/utils/asgi.py#L127-L135 It consumes the messages, which means if you try to call it a second time you won't be able to get at the body. This is efficient - we don't end up with a `request` object property with potentially megabytes of content that we never look at again - but it's inconvenient for cases like middleware or functions where we don't know if the body has been consumed yet or not. Potential solution: set `request._body` the first time it is called, and return that on subsequent calls. Potential optimization: only do this for bodies that are shorter than a certain threshold - maybe 1MB - and raise an exception if you attempt to call `post_body()` multiple times against one of those larger bodies. I'm a bit nervous about that option though, since it could result in errors that don't show up in testing but do show up in production. | 107914493 | issue | {"url": "https://api.github.com/repos/simonw/datasette/issues/2204/reactions", "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} |
