// CreateHeader adds a file to the zip archive using the provided [FileHeader]

// This returns a [Writer] to which the file contents should be written.

使用 `check_same_thread=False` 可以让 FastAPI 在不同线程中使用同一个 SQLite 数据库。这很有必要，因为**单个请求**可能会使用**多个线程**（例如在依赖项中）。

不用担心，我们会按照代码结构确保**每个请求使用一个单独的 SQLModel *会话***，这实际上就是 `check_same_thread` 想要实现的。

### 创建表

然后，我们来添加一个函数，使用 `SQLModel.metadata.create_all(engine)` 为所有*表模型***创建表**。

### 创建会话（Session）依赖项

**`Session`** 会存储**内存中的对象**并跟踪数据中所需更改的内容，然后它**使用 `engine`** 与数据库进行通信。

* Use GCE metadata proxy v0.1.4-r1 to pick up security fixes. ([#60245](https://github.com/kubernetes/kubernetes/pull/60245), [@ihmccreery](https://github.com/ihmccreery))

# v1.8.10

                .max(Comparator.comparingInt(c -> c.getRemoteInterface().getLinkSpeed()))
                .orElseThrow();
        }
        
        if (isMetadataOperation(message)) {
            // For metadata operations, prefer low-latency channels
            return selectLeastLoaded(channels);
        }
        
        // Default to weighted random for general operations
        return selectWeightedRandom(channels);

걱정하지 마세요. 코드가 구조화된 방식으로 인해, 이후에 **각 요청마다 단일 SQLModel *세션*을 사용**하도록 보장할 것입니다. 실제로 그것이 `check_same_thread`가 하려는 것입니다.

### 테이블 생성하기

그 다음 `SQLModel.metadata.create_all(engine)`을 사용하여 모든 *테이블 모델*의 **테이블을 생성**하는 함수를 추가합니다.

### 세션 의존성 생성하기

		if rec.Code == http.StatusNoContent {
			objInfo, err := obj.GetObjectInfo(context.Background(), bucketName, testCase.objectName+"/upload.txt", opts)

 * Update NPN dependency to target `jdk7u60-b13` and `Oracle jdk7u55-b13`.
 * Ensure SPDY variants support zero-length DELETE and POST.
 * Prevent leaking a cache item's InputStreams when metadata read fails.
 * Use a string to identify TLS versions in routes.
 * Add frame logger for HTTP/2.
 * Replacing `httpMinorVersion` with `Protocol`. Expose HTTP/1.0 as a potential protocol.
 * Use `Protocol` to describe framing.
