# 手动绑定

### 背景

有一些服务在初始化过程中需要初始化大量数据, 这个时候我们希望服务不要绑定端口对外提供服务, 而是等初始化完毕后, 在绑定端口提供服务, 我们就需要有这个手工绑定的功能.

### 使用方式

我们在服务的`initialize`中执行:

```c++
//注意tarscpp版本,老版本可能没有这个函数
getBindAdapter(getServerBaseInfo().Application + "." + getServerBaseInfo().ServerName +".HelloObj")->enableManualListen();

//如果3.0.19之前的版本, 只能在模板中的<server>域内配置, manualListen = 1 来实现

```

然后你可以放心初始化的数据, 服务不会绑定业务端口, 当你的数据初始化完毕后, 你可以调用:

```c++
getBindAdapter(getServerBaseInfo().Application + "." + getServerBaseInfo().ServerName +".HelloObj")->manualListen();

```

从而完成端口的主动绑定.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tarscloud.gitbook.io/tarsdocs/tarscpp/tars_bind.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
