with open(image.png,"rb") as f: 在打字稿中？

如何打开 png 文件，如 python 的方法： with open(path+im,"rb") as f: 但在打字稿中？如果我有一个包含一些 png 的文件夹，并且我想在 python 中读取它们并将它们转换为 base 64，我会使用该方法，但是 typescript 中的对应方法是什么？ Sameone 可以帮我吗？

我在 python 中有这段代码：

def image_integrity():
    list_of_sha256 = []
    path = "./nft_test/"
    for im in os.listdir(path):
        with open(path+im,"rb") as f:
            f = base64.b64encode(f.read()) # read entire file as bytes
            h = hashlib.new("sha256")
            h.update(f)
            result = h.digest()
            result = base64.b64encode(result).decode("utf-8")
            print(result)
            list_of_sha256.append(result)
    return list_of_sha256

我想用打字稿重写它。

看来你想从目录中读取。

fs.readFile( path.resolve(__dirname, './data.txt' ), 'utf-8', function(err, buf) 
{
    var data= buf.toString();
    console.log('load', 'OK'.green);
});

seems you are want read from dir.

fs.readFile( path.resolve(__dirname, './data.txt' ), 'utf-8', function(err, buf) 
{
    var data= buf.toString();
    console.log('load', 'OK'.green);
});
