更新帖子ID时出现500内部服务器错误

开发
1

我阅读并遵循了 https://meta.discourse.org/t/reverse-engineer-the-discourse-api/20576，发现端点实际上是 /posts/{id} 而不是 /posts/{id}.json，但我两者都试过了。

Discourse 运行在 Docker 中。以下 Python 代码返回 500 内部错误，我有点不知所措。其他读取操作运行正常（获取主题和帖子等）。API 密钥具有全局读/写权限。

有人能看出哪里出错了？如果不能，我该如何实际调试它？

endpoint = '/posts/6451'  # 也尝试了 /posts/6451.json
api_url = self.base_url + endpoint
headers = {'Api-Username': 'system', 'Api-Key': self.api_key}
raw = "... 这里是足够长且有效的 markdown ..."
data = {
    "post": {
        "raw": raw,
        "edit_reason": "API update",
        "topic_id": self.topic_id,  # 也尝试过注释掉这一行
        "original_text": original_raw,  # 也尝试过注释掉这一行
        "locale": "",  # 也尝试过注释掉这一行
    }
}
response = requests.put(api_url, headers=headers, data=data, timeout=10)
response.raise_for_status()

/logs 显示：TypeError (no implicit conversion of Symbol into Integer) app/controllers/posts_controller.rb:248:in '[]' app/controllers/posts_controller.rb:248:in 'update' app/controllers/application_controller.rb:

app/controllers/posts_controller.rb 的第 248 行在这里（here）（我的本地 discourse 文件是相同的），那是解析 “raw” 字符串的行。我看不出哪里错了……

抱歉。把这个留在这里，以防其他人遇到同样的问题。

调试实际发送的 HTTP 请求时，我注意到 python 发送的 PUT 数据是 \"post=raw\u0026post=edit_reason\"……将 requests.put() 调用中的 data=data 替换为 json=data 就解决了问题。
