firebase putfile在kotlin中

Question

putFile()方法显示kotlin中未解析的引用

 override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if(requestCode==Gallery_Intent && resultCode == Activity.RESULT_OK ) {
            val uri = data!!.data
            val imgstr = FirebaseStorage.getInstance().getReference().child("images")
            uri.putFile(imgstr)
    }

uri.putFile(imgstr)显示错误该怎么办？

Answer 1

putfile()是StorageReference的一种方法。代码应该是：

imgstr.putFile(uri)
