 *
 * This example shows a call with a short 500 millisecond read timeout and a 1000 millisecond
 * write timeout. Original configuration is kept, but can be overriden.
 *
 * ```java
 * OkHttpClient eagerClient = client.newBuilder()
 *     .readTimeout(500, TimeUnit.MILLISECONDS)
 *     .build();
 * Response response = eagerClient.newCall(request).execute();
 * ```

我們身為人，常常會犯錯。軟體幾乎總是有藏在各處的「臭蟲（bugs）」🐛

而我們開發者會在發現這些 bug 後持續改進程式碼、實作新功能（也可能順便加進新的 bug 😅）。

### 小錯誤自動處理 { #small-errors-automatically-handled }

使用 FastAPI 建構 Web API 時，如果我們的程式碼出錯，FastAPI 通常會把它限制在觸發該錯誤的單次請求之中。🛡

用戶端會收到「500 Internal Server Error」，但應用會繼續處理之後的請求，而不是整個崩潰。

### 更嚴重的錯誤 - 當機 { #bigger-errors-crashes }

然而，仍可能有一些情況，我們寫的程式碼「讓整個應用當機」，使 Uvicorn 與 Python 都崩潰。💥
