@ohos.security.certManager (证书管理模块)(系统接口)

证书管理主要提供系统级的证书管理能力,实现证书全生命周期(安装,存储,使用,销毁)的管理和安全使用。

说明:

  • 本模块首批接口从API version 11开始支持。后续版本的新增接口,采用上角标单独标记接口的起始版本。
  • 当前页面仅包含本模块的系统接口,其他公开接口参见@ohos.security.certManager (证书管理模块)

导入模块

import { certificateManager } from '@kit.DeviceCertificateKit';

CMErrorCode

表示调用证书管理相关API的错误码。

系统能力: SystemCapability.Security.CertificateManager

名称 说明
CM_ERROR_NOT_SYSTEM_APP 202 表示应用程序不是系统应用程序。
系统接口: 此接口为系统接口。

certificateManager.getAllAppPrivateCertificates

getAllAppPrivateCertificates(callback: AsyncCallback<CMResult>): void

表示获取所有私有凭据列表,使用Callback回调异步返回结果。

需要权限: ohos.permission.ACCESS_CERT_MANAGER 和 ohos.permission.ACCESS_CERT_MANAGER_INTERNAL

系统能力: SystemCapability.Security.CertificateManager

系统接口: 此接口为系统接口。

参数

参数名 类型 必填 说明
callback AsyncCallback<CMResult> 回调函数。当获取所有私有凭据列表成功时,err为null,data为CMResult对象中的credentialList属性;否则为错误对象。

错误码:

以下错误码的详细介绍请参见证书管理错误码

错误码ID 错误信息
201 Permission verification failed. The application does not have the permission required to call the API.
202 Permission verification failed. A non-system application calls a system API.
401 Parameter error. Possible causes: 1. Mandatory parameters are left unspecified; 2. Incorrect parameter types; 3. Parameter verification failed.
17500001 Internal error. Possible causes: 1. IPC communication failed; 2. Memory operation error; 3. File operation error.

示例

import { certificateManager } from '@kit.DeviceCertificateKit';

try {
  certificateManager.getAllAppPrivateCertificates((err, cmResult) => {
    if (err != null) {
      console.error(`Failed to get all app private certificates. Code: ${err.code}, message: ${err.message}`);
    } else {
      if (cmResult == undefined) { // 私有凭据个数为0时,返回cmResult为undefined。
        console.info('the count of the app private certificates is 0');
      } else if (cmResult.credentialList == undefined) {
        console.info('The result of getting all app private certificates is undefined.');
      } else {
        let list = cmResult.credentialList;
        console.info('Succeeded in getting all app private certificates.');
      }
    }
  });
} catch (error) {
  console.error(`Failed to get all app private certificates. Code: ${error.code}, message: ${error.message}`);
}

certificateManager.getAllAppPrivateCertificates

getAllAppPrivateCertificates(): Promise<CMResult>

系统接口: 此接口为系统接口。

返回值

类型 说明
Promise<CMResult> Promise对象。表示获取所有私有凭据列表的结果,返回值为CMResult对象中的credentialList属性。
