The response expected by MinIO, is a JSON body with a boolean:

```json
{
    "result": true
}
```

The following structure is also accepted:

```json
{
    "result": {
        "allow": true
    }
}
```

    assert response.status_code == 200, response.text
    assert response.json() == {
        "sub_items": [{"name": "subitem", "sub_items": []}],
        "name": "item",
    }

    response = client.get("/items/recursive-submodel")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "name": "item",
        "sub_items1": [
            {

    response = client.get(path)
    assert response.status_code == expected_status
    assert response.json() == expected_response

Das Frontend (das im Browser läuft) würde also versuchen, `/openapi.json` zu erreichen und wäre nicht in der Lage, das OpenAPI-Schema abzurufen.

Da wir für unsere Anwendung einen Proxy mit dem Pfadpräfix `/api/v1` haben, muss das Frontend das OpenAPI-Schema unter `/api/v1/openapi.json` abrufen.

```mermaid
graph LR

browser("Browser")

哪怕所有代码都假设只有 `/app`。

代理只在把请求传送给 Uvicorn 之前才会**移除路径前缀**，让应用以为它是在 `/app` 提供服务，因此不必在代码中加入前缀 `/api/v1`。

但之后，在（前端）打开 API 文档时，代理会要求在 `/openapi.json`，而不是 `/api/v1/openapi.json` 中提取 OpenAPI 概图。

因此， （运行在浏览器中的）前端会尝试访问 `/openapi.json`，但没有办法获取 OpenAPI 概图。

这是因为应用使用了以 `/api/v1` 为路径前缀的代理，前端要从 `/api/v1/openapi.json`  中提取 OpenAPI 概图。

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]

我们可以将 OpenAPI JSON 下载到一个名为`openapi.json`的文件中，然后使用以下脚本**删除此前缀的标签**：

```Python
{!../../docs_src/generate_clients/tutorial004.py!}
```

通过这样做，操作ID将从类似于 `items-get_items` 的名称重命名为 `get_items` ，这样客户端生成器就可以生成更简洁的方法名称。

### 使用预处理的OpenAPI生成TypeScript客户端

现在，由于最终结果保存在文件openapi.json中，你可以修改 package.json 文件以使用此本地文件，例如：

```JSON  hl_lines="7"
{
  "name": "frontend-app",

    assert response.status_code == 200, response.text
    assert response.text == "Hello World"


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "openapi": "3.1.0",
        "info": {"title": "FastAPI", "version": "0.1.0"},
        "paths": {
            "/": {
                "get": {
