/// warning | 警告

可在一个*路径操作*中声明多个 `Form` 参数，但不能同时声明要接收 JSON 的 `Body` 字段。因为此时请求体的编码是 `application/x-www-form-urlencoded`，不是 `application/json`。

这不是 **FastAPI** 的问题，而是 HTTP 协议的规定。

## 小结

    private val HTTP_URL_SCHEMES = listOf("http", "https")
    private val KNOWN_FAILURES =
      listOf(
        "Parsing: <http://example\t.\norg> against <http://example.org/foo/bar>",
        "Parsing: <http://f:0/c> against <http://example.org/foo/bar>",
        "Parsing: <http://f:00000000000000/c> against <http://example.org/foo/bar>",
        "Parsing: <http://f:\n/c> against <http://example.org/foo/bar>",

Наприклад, такі адреси вважаються різними джерелами:

* `http://localhost`
* `https://localhost`
* `http://localhost:8080`

Навіть якщо вони всі містять `localhost`, вони мають різні протоколи або порти, що робить їх окремими "джерелами".
