对firebase来说真的是个新手，代码水平很低。我试图找出一个错误，自定义404没有显示，或者当重写更改时，应用程序就不起作用。
"rewrites": [
{
"source": "**",
"function": "app"
}
]
这会将所有内容重定向到应用程序，并且应用程序功能正常。但是，404.html不会显示是否尝试了错误的URL。有一个通用的"；无法获取/asdfasd"；
将其更改为
"rewrites": [
{
"source": "/",
"function": "app"
}
]
这将正确显示自定义404.html。
然而，有了这一点，一个函数会以404响应此配置，从而破坏应用程序。从函数/index.js:
app.post('/sendsmstoconsumer', (request, response) => {
client.messages
.create({body: request.body.message, from: '+15555555555', to: request.body.phone})
.then(message => {
response.send("Your message: " + request.body.message + " has been sent!")
});
})
我已经尝试了许多类似以下的变体，但我只是缺少了一些东西。
{
"source": "/",
"function": "app"
},
{
"source": "/sendsmstoconsumer",
"function": "sms"
}
]
change functions/index.js:
exports.sms = functions.httpsOnRequest((request, response) => {
client.messages
.create({body: request.body.message, from: '+15555555555', to: request.body.phone})
.then(message => {
response.send("Your message: " + request.body.message + " has been sent!")
});
})
如果能以正确的方式构建重写，或更改自定义404和应用程序的功能，我将不胜感激。我似乎被其中一个卡住了。
谢谢。

默认情况下，重写不会"跌倒"；一旦匹配，云功能发送的响应将始终直接返回给用户。实际上有一种方法可以解决这个问题：如果您的响应主体包含X-Cascade: PASS的标头。
在这种情况下，Firebase主机将进入默认404行为(包括自定义404.html(。您应该能够将其添加到您的Express应用程序中，如下所示：
// *AFTER* all other endpoints
app.use((req, res) => {
res.set('X-Cascade', 'PASS');
res.status(404).send('Not Found');
});
感谢Michael Bleigh的回答，我们找到了一个解决方案，但必须指定404.html文件。
app.use((req, res) => {
res.set('X-Cascade', 'PASS')
res.status(404).redirect('404.html')
})
