## Origin { #origin }

An origin is the combination of protocol (`http`, `https`), domain (`myapp.com`, `localhost`, `localhost.tiangolo.com`), and port (`80`, `443`, `8080`).

So, all these are different origins:

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

Even if they are all in `localhost`, they use different protocols or ports, so, they are different "origins".

## Steps { #steps }

## 源 { #origin }

源是协议（`http`，`https`）、域（`myapp.com`，`localhost`，`localhost.tiangolo.com`）以及端口（`80`、`443`、`8080`）的组合。

因此，这些都是不同的源：

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

即使它们都在 `localhost` 中，但是它们使用不同的协议或者端口，所以它们都是不同的「源」。

## 步骤 { #steps }

假设你的浏览器中有一个前端运行在 `http://localhost:8080`，并且它的 JavaScript 正在尝试与运行在 `http://localhost` 的后端通信（因为我们没有指定端口，浏览器会采用默认的端口 `80`）。

## 확인하기 { #check-it }

이제 `/v1/` 경로에 있는 모든 요청은 Flask 애플리케이션에서 처리됩니다.

그리고 나머지는 **FastAPI**에 의해 처리됩니다.

실행하고 [http://localhost:8000/v1/](http://localhost:8000/v1/)로 이동하면 Flask의 응답을 볼 수 있습니다:

```txt
Hello, World from Flask!
```

그리고 [http://localhost:8000/v2](http://localhost:8000/v2)로 이동하면 **FastAPI**의 응답을 볼 수 있습니다:

```JSON
{
    "message": "Hello World"
}

        assertEquals(exp, transformer.getHostOnFile(url));

        url = "file:";
        exp = "localhost";
        assertEquals(exp, transformer.getHostOnFile(url));

        url = "file://";
        exp = "localhost";
        assertEquals(exp, transformer.getHostOnFile(url));

        url = "file:///";
        exp = "localhost";
        assertEquals(exp, transformer.getHostOnFile(url));

        url = "file://///";

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware

app = FastAPI()

origins = [
    "http://localhost.tiangolo.com",
    "https://localhost.tiangolo.com",
    "http://localhost",
    "http://localhost:8080",
]

app.add_middleware(
    CORSMiddleware,
    allow_origins=origins,
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)


@app.get("/")

And the rest will be handled by **FastAPI**.

If you run it and go to [http://localhost:8000/v1/](http://localhost:8000/v1/) you will see the response from Flask:

```txt
Hello, World from Flask!
```

And if you go to [http://localhost:8000/v2](http://localhost:8000/v2) you will see the response from FastAPI:

```JSON
{
    "message": "Hello World"
}

      with:
        path: ~/go/pkg/mod
        key: ${{ runner.os }}-go-${{ matrix.go }}-${{ hashFiles('tests/go.mod') }}

    - name: Tests
      run: GITHUB_ACTION=true GORM_DIALECT=mysql GORM_DSN="gorm:gorm@tcp(localhost:9910)/gorm?charset=utf8&parseTime=True" ./tests/tests_all.sh

  mariadb:
    strategy:
      matrix:
        dbversion: [ 'mariadb:latest' ]
        go: ['stable', 'oldstable']
        platform: [ ubuntu-latest ]

## チェック { #check-it }

これで、パス `/v1/` 配下へのすべてのリクエストは Flask アプリケーションが処理します。

それ以外は **FastAPI** が処理します。

実行して [http://localhost:8000/v1/](http://localhost:8000/v1/) にアクセスすると、Flask からのレスポンスが表示されます:

```txt
Hello, World from Flask!
```

さらに [http://localhost:8000/v2](http://localhost:8000/v2) にアクセスすると、FastAPI からのレスポンスが表示されます:

```JSON
{
    "message": "Hello World"
}
