这里，我们使用 `SessionDep` 依赖项（一个 `Session` ）将新的 `Hero` 添加到 `Session` 实例中，提交更改到数据库，刷新 hero 中的数据，并返回它。

### 读取 Hero 类

我们可以使用 `select()` 从数据库中**读取** `Hero` 类，并利用 `limit` 和 `offset` 来对结果进行分页。

### 读取单个 Hero

我们可以**读取**单个 `Hero` 。

   * To differentiate the two cases we ping the server when a stream times out. If the overall
   * connection is fine the ping will receive a pong; otherwise it won't.
   *
   * The deadline to respond to this ping attempts to limit the cost of being wrong. If it is too
   * long, streams created while we await the pong will reuse broken connections and inevitably
   * fail. If it is too short, slow connections will be marked as failed and extra TCP and TLS

    Authenticators should identify preemptive authentications by the presence of a challenge whose
    scheme is "OkHttp-Preemptive".

 *  **OkHttp now offers full-operation timeouts.** This sets a limit on how long the entire call may
    take and covers resolving DNS, connecting, writing the request body, server processing, and
    reading the full response body. If a call requires redirects or retries all must complete within

- kube-scheduler removed `AzureDiskLimits` ,`CinderLimits` `EBSLimits` and `GCEPDLimits` plugin. Given the corresponding CSI driver reports how many volumes a node can handle in NodeGetInfoResponse, the kubelet stores this limit in CSINode and the scheduler then knows the limit of the driver on the node. Removed plugins AzureDiskLimits, CinderLimits, EBSLimits and GCEPDLimits if you explicitly enabled them in the scheduler config. ([#124003](https://github.com/kubernetes/kubernetes/pull/124003), ...
