Right before deciding to build **FastAPI** I found **APIStar** server. It had almost everything I was looking for and had a great design.

It was one of the first implementations of a framework using Python type hints to declare parameters and requests that I ever saw (before NestJS and Molten). I found it more or less at the same time as Hug. But APIStar used the OpenAPI standard.

				if err != nil {
					logger.FatalIf(err, "Unable to initialize MinIO server with [%s] invalid entry found in MINIO_PUBLIC_IPS", endpoint)
				}
				for _, addr := range addrs {
					domainIPs.Add(addr)
				}
			}
			domainIPs.Add(endpoint)
		}
		updateDomainIPs(domainIPs)
	} else {
		// Add found interfaces IP address to global domain IPS,
		// loopback addresses will be naturally dropped.

                    .build());
            options.addOption(Option.builder(CACHE_ARTIFACT_NOT_FOUND)
                    .longOpt("cache-artifact-not-found")
                    .hasArg()
                    .desc(
                            "Defines caching behaviour for 'not found' artifacts. Supported values are 'true' (default), 'false'.")
                    .build());

- 客户端没有执行操作的权限
- 客户端没有访问资源的权限
- 客户端要访问的项目不存在
- 等等 ...

遇到这些情况时，通常要返回 **4XX**（400 至 499）**HTTP 状态码**。

**4XX** 状态码与表示请求成功的 **2XX**（200 至 299） HTTP 状态码类似。

只不过，**4XX** 状态码表示客户端发生的错误。

大家都知道**「404 Not Found」**错误，还有调侃这个错误的笑话吧？

## 使用 `HTTPException`

向客户端返回 HTTP 错误响应，可以使用 `HTTPException`。

### 导入 `HTTPException`

```Python hl_lines="1"
{!../../docs_src/handling_errors/tutorial001.py!}

```

	LatestModTime time.Time `msg:"lm"`

	Versions     []FileInfo `msg:"vs"`
	FreeVersions []FileInfo `msg:"fvs"`

// findVersionIndex will return the version index where the version
// was found. Returns -1 if not found.
func (f *FileInfoVersions) findVersionIndex(v string) int {
	if f == nil || v == "" {

	}
	if v == nullVersionID {
		for i, ver := range f.Versions {
			if ver.VersionID == "" {

Setting CC is not necessary if the toolchain is built with CC_FOR_TARGET set.

To use the go tool to run individual programs and tests, put $GOROOT/bin into PATH to ensure
the go_ios_$GOARCH_exec wrapper is found. For example, to run the archive/tar tests:

	export PATH=$GOROOT/bin:$PATH
	GOOS=ios GOARCH=amd64 CGO_ENABLED=1 go test archive/tar

The go_ios_exec wrapper uses GOARCH to select the emulator (amd64) or the device (arm64).
