3. 获取rawfile下面的文件内容，将其复制到沙箱路径下

	getContext(this).resourceManager.getRawFileContent('simhei.ttf', (_err, value) => {
           let myBuffer: ArrayBufferLike = value.buffer;
           let context = getContext(this); //沙箱路径
           let filePath = context.filesDir + '/copy_simhei.ttf';
           let file = fileIo.openSync(filePath, fileIo.OpenMode.READ_WRITE | fileIo.OpenMode.CREATE);
           let writeLen = fileIo.writeSync(file.fd, myBuffer);
           PhLog.info(' file succeed and size is:' + writeLen);
           fileIo.closeSync(file);
         });
