节点Express"favicon.ico"找不到错误 [英] Node Express "favicon.ico" not found error

问题描述

我正在尝试通过使用Express作为查询字符串传递的URL下载照片，但是每次尝试使用它时，都会出现错误:无效的URI"favicon.ico" 有没有办法让我的浏览器停止请求收藏夹图标?对于下载图像，我使用的是 image-downloader 软件包( NPM页面)

I'm trying to download a photo through a URL passed as a query string using Express, but every time I try to use it, I get Error: Invalid URI "favicon.ico" Is there a way I can get my browser to stop requesting a favicon? For downloading images, I'm using the image-downloader package (NPM page)

代码:

app.get('/:url', (req, res) => {
let url = req.params.url;
const options = {
    url: url,
    dest: /path'
};
download.image(options)
    .then(({ filename, image }) => {
        console.log('File saved to ', filename);
})
    .catch((err) => {
        console.log(err);
    });
res.send("Done");

});

推荐答案

仅在服务器中为favicon.ico路由可能是最简单的.

It's probably easiest to just make a route for favicon.ico in your server.

app.get('/favico.ico', (req, res) => {
    res.sendStatus(404);
});

当然，如果需要，您实际上也可以发送一个有效的图标，但这至少将使Express服务器不会显示错误.

Of course, you could actually send a valid icon too if you wanted, but this will at least keep your Express server from showing an error.

仅供参考，这与 image-downloader 无关.这与浏览器请求一个favico.ico图标有关，该图标用于显示在URL栏中(以及浏览器UI中的其他位置).如果您的服务器为favicon.ico返回404，则浏览器将在其UI中使用通用图标.

FYI, this has nothing to do with the image-downloader. This has to do with the browser requesting a favico.ico icon that it uses to show in the URL bar (and some other places in the browser UI). If your server returns a 404 for favicon.ico, the browser will use a generic icon in its UI.

如果您想使自己成为一个简单的favico.ico，可以在此处进行操作，它将帮助您生成一个，然后您可以将上述路线更改为:

If you want to make yourself a simple favico.ico, you can go here and it will help you generate one and then you can change the above route to:

app.get('/favico.ico', (req, res) => {
    res.sendFile("myfavico.ico");
});
