### アプリケーションの作成

- `main.py` を作成し、以下のコードを入力します:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: str = None):
    return {"item_id": item_id, "q": q}
```

  @GwtIncompatible // different overflow behavior; could probably be made to work by using ~~
  public void testConcat_overflow_negative() {
    int dim1 = 1 << 16;
    int dim2 = 1 << 15;
    assertThat(dim1 * dim2).isLessThan(0);
    testConcatOverflow(dim1, dim2);
  }

 *  Fix: Configure the multiplatform artifact (`com.squareup.okhttp3:okhttp:3.x.x`) to depend on the
    JVM artifact (`com.squareup.okhttp3:okhttp-jvm:3.x.x`) for Maven builds. This should work-around
    an issue where Maven doesn't interpret Gradle metadata.
 *  Fix: Make another attempt at supporting Kotlin 1.5.31 at runtime. We were crashing on
    `DurationUnit` which was a typealias in 1.5.x.
