HarmonyOS 鸿蒙Next JS开发camera拍摄的照片拷贝到internal://cache/里报错 call fail callback fail, code: 202, data: illegal uri:xxxxxxxx 这是拍照的代码，拍摄成功会输出照片路径

##拍照成功路径==>file:///data/data/com.example.http/files/cache_images/IMG_20220916_215355047.jpg

var camera_take = this;
var camera = this.$element('camera');
camera.takePhoto({
    quality:'high',
    success(result){
        console.info('##-------------拍照成功回调------'+result)
        camera_take.src = result.uri
        console.log("##拍照成功路径==>"+camera_take.src);
    },
    fail(result){
        console.info('##-------------拍照失败回调------'+result)
    },
    complete(result){
        console.info('##-------------拍照结束回调------'+result)
    }
})

这是拷贝的代码，

file.copy({
    srcUri: this.src,
    dstUri: 'internal://cache/photo_copy.jpg',
    success: function(uri) {
        console.log('call success callback success');
    },
    fail: function(data, code) {
        console.error('call fail callback fail, code: ' + code + ', data: ' + data);
    },
});

运行后报错

app Log: call fail callback fail, code: 202, data: illegal uri:file:///data/data/com.example.http/files/cache_images/IMG_20220916_215355047.jpg

意思就是照片的路径不合法，但是照片的路径是不能自定义的，怎么才能实现将拍摄的照片拷贝到临时目录里面呢？
