资源管理changeLog

cl.resourceManager.1 资源API9部分多工程接口命名变更

资源管理从API9开始提供接口的错误码和错误信息返回，涉及API9提供的部分多工程接口需要适配。从API9开始作以下变更：

资源API部分多工程接口需要用新的接口替换，参数不变。

变更影响

基于此前版本开发的应用，涉及下面多工程接口的JS接口需要替换为新的接口。

关键接口/组件变更

涉及接口	对应替换接口
getString(resource: Resource, callback: AsyncCallback<string>): void;	getStringValue(resource: Resource, callback: AsyncCallback<string>): void;
getString(resource: Resource): Promise<string>;	getStringValue(resource: Resource): Promise<string>;
getStringArray(resource: Resource, callback: AsyncCallback<Array<string>>): void;	getStringArrayValue(resource: Resource, callback: AsyncCallback<Array<string>>): void;
getStringArray(resource: Resource): Promise<Array<string>>;	getStringArrayValue(resource: Resource): Promise<Array<string>>;
getMedia(resource: Resource, callback: AsyncCallback<Uint8Array>): void;	getMediaContent(resource: Resource, callback: AsyncCallback<Uint8Array>): void;
getMedia(resource: Resource): Promise<Uint8Array>;	getMediaContent(resource: Resource): Promise<Uint8Array>;
getMediaBase64(resource: Resource, callback: AsyncCallback<string>): void;	getMediaContentBase64(resource: Resource, callback: AsyncCallback<string>): void;
getMediaBase64(resource: Resource): Promise<string>;	getMediaContentBase64(resource: Resource): Promise<string>;
getPluralString(resource: Resource, num: number, callback: AsyncCallback): void;	getPluralStringValue(resource: Resource, num: number, callback: AsyncCallback<string>): void;
getPluralString(resource: Resource, num: number): Promise<string>;	getPluralStringValue(resource: Resource, num: number): Promise<string>;

适配指导

以getMedia修改为getMediaContent的callback调用为例，其promise方式类似，只需修改函数名，且增加错误码和错误信息返回，其它不变。示例代码如下：

变更前：getMedia(resource: Resource, callback: AsyncCallback): void;

let resource = {
bundleName: "com.example.myapplication",
moduleName: "entry",
id: $r('app.media.test').id
};
this.context.resourceManager.getMedia(resource, (error, value) => {
if (error != null) {
  console.log("error is " + error);
} else {
  let media = value;
}
});

变更后：getMediaContent(resource: Resource, callback: AsyncCallback): void;

let resource = {
bundleName: "com.example.myapplication",
moduleName: "entry",
id: $r('app.media.test').id
};
try {
this.context.resourceManager.getMediaContent(resource, (error, value) => {
  if (error != null) {
    console.log("error is " + error);
  } else {
    let media = value;
  }
});
} catch (error) {
console.error(`callback getMediaContent failed, error code: ${error.code}, message: ${error.message}.`)
}
