# Context

The **Context** module provides context for abilities or applications. It allows access to application-specific resources, as well as permission requests and verification.

> **NOTE**
>
> The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> The APIs of this module can be used only in the FA model.

## Modules to Import

```ts
import featureAbility from '@ohos.ability.featureAbility';
```

## Usage

The **Context** object is created in a **featureAbility** and returned through its [getContext](js-apis-ability-featureAbility.md#featureabilitygetcontext) API. Therefore, you must import the **@ohos.ability.featureAbility** package before using the **Context** module. An example is as follows:

<!--code_no_check_fa-->
```ts
import featureAbility from '@ohos.ability.featureAbility';

let context: featureAbility.Context = featureAbility.getContext();
context.getOrCreateLocalDir().then((data) => {
    console.info(`getOrCreateLocalDir data: ${JSON.stringify(data)}`);
});
```

## Context.getOrCreateLocalDir<sup>7+</sup>

getOrCreateLocalDir(callback: AsyncCallback\<string>): void

Obtains the local root directory of the application. This API uses an asynchronous callback to return the result.

If this API is called for the first time, a root directory will be created.

**System capability**: SystemCapability.Ability.AbilityRuntime.Core

**Parameters**

| Name      | Type                    | Mandatory  | Description           |
| -------- | ---------------------- | ---- | ------------- |
| callback | AsyncCallback\<string> | Yes   | Callback used to return the local root directory.|

**Example**

<!--code_no_check_fa-->
```ts
import featureAbility from '@ohos.ability.featureAbility';

let context: featureAbility.Context = featureAbility.getContext();
context.getOrCreateLocalDir((error, data)=>{
    if (error && error.code !== 0) {
        console.error(`getOrCreateLocalDir fail, error: ${JSON.stringify(error)}`);
    } else {
        console.log(`getOrCreateLocalDir success, data: ${JSON.stringify(data)}`);
    }
});
```


## Context.getOrCreateLocalDir<sup>7+</sup>

context.getOrCreateLocalDir().then((data) => {
    console.info(`getOrCreateLocalDir data: ${JSON.stringify(data)}`);
});
```

## Context.verifyPermission<sup>7+</sup>

verifyPermission(permission: string, options: PermissionOptions, callback: AsyncCallback\<number>): void

| callback   | AsyncCallback\<number>                  | Yes   | Callback used to return the permission verification result. The value **0** means that the PID and UID have the given permission, and the value **-1** means the opposite.|

**Example**

<!--code_no_check_fa-->
```ts
import featureAbility from '@ohos.ability.featureAbility';
import bundle from '@ohos.bundle.bundleManager';
import { BusinessError } from '@ohos.base';

let context: featureAbility.Context = featureAbility.getContext();
