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
