# formfwk子系统ChangeLog

## cl.formfwk.1 @ohos.app.form.formHost.d.ts部分接口移出，接口权限变动

1. @ohos.app.form.formHost.d.ts中涉及监听和获取卡片动态信息的接口移至@ohos.app.form.formObserver.d.ts;
2. 涉及接口需申请权限由ohos.permission.REQUIRE_FORM修改为ohos.permission.OBSERVE_FORM_RUNNING。

**变更影响**

对于已发布的js接口，可能影响三方应用的兼容性。

**关键的接口/组件变更**

涉及接口移动、权限修改前的接口原型：

|     接口      | 修改前所属d.ts | 修改后所属d.ts | 修改前所需权限 | 修改后所需权限 |
|   --------    |   --------    |   --------    | --------      | --------  |
| on('formAdd') | @ohos.app.form.formHost.d.ts | @ohos.app.form.formObserver.d.ts | ohos.permission.REQUIRE_FORM | ohos.permission.OBSERVE_FORM_RUNNING | @ohos.app.form.formHost.d.ts | @ohos.app.form.formObserver.d.ts | ohos.permission.REQUIRE_FORM|ohos.permission.OBSERVE_FORM_RUNNING|

**适配指导**

已使用相关接口开发的应用工程，需要对接口进行适配。从OpenHarmony 4.0.9.5版本起，相关接口使用应导入@ohos.app.form.formObserver.d.ts，并申请ohos.permission.OBSERVE_FORM_RUNNING权限。

**示例：**
```js
import formObserver from @ohos.app.form.formObserver.d.ts;

try {
  formObserver.getRunningFormInfos((error, data) => {
    if (error) {
      console.error(`error, code: ${error.code}, message: ${error.message}`);
    } else {
      console.log('formHost getRunningFormInfos, data: ${JSON.stringify(data)}');
    }
  }, 'com.example.ohos.formjsdemo');
} catch(error) {
  console.error(`catch error, code: ${error.code}, message: ${error.message}`);
}
```
