DevEco Studio端云协同开发之云存储

在DevEco Studio中使用云存储服务，首先需要在项目的config.json文件中配置云存储的权限。以下是一个配置示例：

{
  "module": {
    "package": "com.huawei.codelab.deveco",
    "name": "codelab",
    "type": "entry",
    "deviceType": [
      "phone"
    ],
    "distribute": {
      "module": "entry"
    }
  },
  "app": {
    "bundleName": "com.huawei.codelab.deveco",
    "vendor": "huawei",
    "version": {
      "code": 1000000,
      "name": "1.0.0"
    }
  },
  "deviceConfig": {},
  "permission": {
    "desc": [
      "This is example for cloud storage usage"
    ],
    "permission": [
      {
        "name": "com.huawei.hms.cordova.scan.permission.READ_EXTERNAL_STORAGE",
        "desc": "read external storage permission",
        "usage": [
          "CAMERA_SERVICE"
        ],
        "level": "normal",
        "reason": "To scan barcode"
      },
      {
        "name": "com.huawei.hms.cordova.scan.permission.WRITE_EXTERNAL_STORAGE",
        "desc": "write external storage permission",
        "usage": [
          "CAMERA_SERVICE"
        ],
        "level": "normal",
        "reason": "To scan barcode"
      },
      {
        "name": "com.huawei.hms.cordova.scan.permission.ACCESS_FINE_LOCATION",
        "desc": "access fine location permission",
        "usage": [
          "LOCATION_SERVICE"
        ],
        "level": "normal",
        "reason": "To get location information"
      }
    ]
  },
  "sdk": {
    "compileSdkVersion": 29,
    "targetSdkVersion": 29
  }
}

在这个配置中，我们为应用添加了读写外部存储和访问位置的权限。

接下来，在代码中使用云存储服务，你需要先初始化云存储实例，然后调用相关的API进行文件的上传、下载等操作。以下是一个简单的示例代码：

// 引入华为云存储服务
import { HMSAgent } from '@hmscore/service-cloud-storage-web-sdk';
 
// 初始化华为云存储服务
const hmsInstance = new HMSAgent();
 
// 上传文件到华为云存储
async function uploadFile(filePath) {
  try {
    const result = await hmsInstance.putFile(filePath);
    console.log('File uploaded:', result);
  } catch (error) {
    console.error('Upload failed:', error);
  }
}
 
// 从华为云存储下载文件
async function downloadFile(filePath) {
  try {
    const result = await hmsInstance.getFile(filePath);
    console.log('File downloaded:', result);
  } catch (error) {
    console.error('Download failed:', error);
  }
}
 
// 使用示例
uploadFile('/path/to/your/file.jpg');
downloadFile('/path/to/your/file.jpg');

请注意，上述代码仅为示例，实际使用时需要确保你已经正确安装了华为云存储服务的SDK，并且已经在项目的config.json文件中配置了必要的权限。此外，具体的API调用方法和参数可能会随SDK版本而变化，请参考
