之后，对于你的生产应用程序，你可能会想要使用像 **PostgreSQL** 这样的数据库服务器。

/// tip | 提示

有一个使用 **FastAPI** 和 **PostgreSQL** 的官方项目生成器，其中包括了前端和更多工具： [https://github.com/fastapi/full-stack-fastapi-template](https://github.com/fastapi/full-stack-fastapi-template)

///

这是一个非常简单和简短的教程。如果你想了解一般的数据库、SQL 或更高级的功能，请查看 [SQLModel 文档](https://sqlmodel.tiangolo.com/)。

## 安装 `SQLModel` { #install-sqlmodel }

首先，确保你创建并激活了[虚拟环境](../virtual-environments.md)，然后安装 `sqlmodel`：

          // 1 MiB.
          maxSize = 10L * 1024L * 1024L,
        ),
      ).build()

  fun run() {
    val request =
      Request
        .Builder()
        .url("http://publicobject.com/helloworld.txt")
        .build()

    val response1Body =
      client.newCall(request).execute().use {
        if (!it.isSuccessful) throw IOException("Unexpected code $it")

        .protocols(Collections.singletonList(Protocol.H2_PRIOR_KNOWLEDGE))
        .build();

    Request request = new Request.Builder()
        .url("http://publicobject.com/helloworld.txt")
        .build();

    try (Response response = client.newCall(request).execute()) {
      System.out.println(response.body().string());
    }

    server.shutdown();
    socketFile.delete();
