### Other notable improvements

  * Job was Beta in 1.1 and is GA in 1.2 .
     * <code>apiVersion: batch/v1 </code>is now available.  You now do not need to specify the <code>.spec.selector</code> field — a [unique selector is automatically generated ](http://kubernetes.io/docs/user-guide/jobs/#pod-selector)for you.

你可以**修改**这些操作 ID 的**生成**方式，使之更简单，从而在客户端中得到**更简洁的方法名**。

在这种情况下，你需要用其他方式确保每个操作 ID 依然是**唯一**的。

例如，你可以确保每个*路径操作*都有一个标签，然后基于**标签**和*路径操作***名称**（函数名）来生成操作 ID。

### 自定义唯一 ID 生成函数 { #custom-generate-unique-id-function }

FastAPI 为每个*路径操作*使用一个**唯一 ID**，它既用于**操作 ID**，也用于请求或响应里任何需要的自定义模型名称。

你可以自定义这个函数。它接收一个 `APIRoute` 并返回一个字符串。

例如，这里使用第一个标签（你很可能只有一个标签）和*路径操作*名称（函数名）。

// retrieved from a peer, along with errors if any
type PeerResourceMetrics struct {
	Metrics map[MetricSubsystem]ResourceMetrics
	Errors  []string
}

// ResourceMetrics is a map of unique key identifying
// a resource metric (e.g. reads_per_sec_{node}_{drive})
// to its data
type ResourceMetrics map[string]ResourceMetric

// ResourceMetric represents a single resource metric

   * equivalently, if this inverse view contains a key that is equal to {@code value}).
   *
   * <p>Due to the property that values in a BiMap are unique, this will tend to execute in
   * faster-than-linear time.
   *
   * @param value the object to search for in the values of this BiMap
   * @return true if a mapping exists from a key to the specified value
   */

// conflicting names will be treated as an error. Note that this option has no
// effect if a prefix is set, since the prefix will guarantee all names are
// unique. Defaults to false.
TF_CAPI_EXPORT extern void TF_ImportGraphDefOptionsSetUniquifyNames(
    TF_ImportGraphDefOptions* opts, unsigned char uniquify_names);

   * We already know how much time it takes to serve 3 fresh permits: if the rate is
   * "1 token per second", then this will take 3 seconds. But what does it mean to serve 7 stored
   * permits? As explained above, there is no unique answer. If we are primarily interested to deal
   * with underutilization, then we want stored permits to be given out /faster/ than fresh ones,

你可以**修改**這些操作 ID 的**產生方式**，讓它們更簡潔，並在用戶端中得到**更簡潔的方法名稱**。

在這種情況下，你需要用其他方式確保每個操作 ID 都是**唯一**的。

例如，你可以確保每個 *路徑操作* 都有標籤，接著根據**標籤**與 *路徑操作* 的**名稱**（函式名稱）來產生操作 ID。

### 自訂唯一 ID 產生函式 { #custom-generate-unique-id-function }

FastAPI 會為每個 *路徑操作* 使用一個**唯一 ID**，它會被用於**操作 ID**，以及任何請求或回應所需的自訂模型名稱。

你可以自訂該函式。它接收一個 APIRoute 並回傳字串。

例如，下面使用第一個標籤（你通常只會有一個標籤）以及 *路徑操作* 的名稱（函式名稱）。
