目前，我从云存储桶下载图像，在base64中对其进行编码，然后将其传递到img标记的router.post('/images', function(req, res, next) {
var image = bucket.file(req.body.image);
image.download(function(err, contents) {
if (err) {
console.log(err);
} else {
var resultImage = base64_encode(contents);
var index = req.body.index;
var returnObject = {
image: resultImage,
index: index
}
res.send(returnObject);
}
});
});
属性中的数据uri。
还有其他办法吗？

图片是否可公开阅读？如果是这样，你可以使用
<img src="http://<bucket>.storage.googleapis.com/<object>">
否则，您需要为GET操作生成signed URL，可以在图像标记中使用。
