投稿のオーナーを変更しようとするとAPIコールで500 Internal Server Error

lemonchan · 2024 年 9 月 7 日午後 7:51

こんにちは！API経由で投稿のオーナーを変更しようとしたところ、500 Internal Server Errorが発生しました。正しいエンドポイントを取得するためにhttps://meta.discourse.org/t/reverse-engineer-the-discourse-api/20576を参考にし、正しいパラメータで再現しましたが、HTTP 500しか返ってきませんでした。

Topic IDは159、Post IDは196です（/t/159.jsonより）。以下のPOSTリクエストを/t/159/change-owner.jsonに送信しました。

# ライブラリはaiohttp、言語はPython
session = aiohttp.ClientSession("http://dspacl.itslemonchan.com", headers={
    "Api-Key": "REDACTED",
    "Api-Username": "system",
    "User-Agent": "lemon/0.1"
})
data = {
    "post_ids": [
        196
    ],
    "username": "lemon"
}
async with session.post("/t/159/change-owner.json", data=data) as resp:
    txt = await resp.text()  # メッセージがないか確認するためですが、何もありませんでした
    resp.raise_for_status()

これによりInternal Server Errorが発生し、何も起こりません。ログを確認したところ、以下のエラーが出ています。

こんにちは、試してみてください：

data = {
    "post_ids[]": 196,
    "username": "lemon"
}

興味深いことに、これはPythonからは機能しますがPostmanでは機能しません。しかし、元のデータはPostmanでは機能しますがPythonでは機能しません。
