HarmonyOS raw音频文件读取转为字节流？

Question

raw音频文件读取转为字节流，Int8Array。请问代码怎么写

Answer 1

raw音频文件读取转为字节流:

通过resourceManager 来读取：

代码：

try {
  this.context.resourceManager.getRawFileContent("test.xml").then(value => {
    let rawFile = value;
  }).catch(error => {
    console.log("getRawFileContent promise error is " + error);
  });
} catch (error) {
  console.error(`promise getRawFileContent failed, error code: ${error.code}, message: ${error.message}.`)
}
