Question

这是我的代码我正在运行服务器，但我无法获取页面index.html 错误是

x = np.random.randn(100)
y = np.random.randn(100)
line = 0.5*np.linspace(-4, 4, 100)
x_line = np.linspace(-4, 4, 100)

fig, ax = plt.subplots(figsize=(8,5))
df = pd.DataFrame({"x": x, "y":y})
#You pass the wanted axis to the ax argument
df.plot(kind='scatter', x='x', y='y',title="Nice title", grid=True,fontsize=10, ax=ax) 
ax.plot(line, x_line, zorder=-1)

错误是

    app.get('/',function(request,response){
  console.log("/");
   response.sendFile(__dirname+"/views/index.html");
})

我不认为服务器正在收到This 127.0.0.1 page can’t be found No webpage was found for the web address: http://127.0.0.1:5000/home HTTP ERROR 404请求。我没有看到get被叫。

整个代码：

console.log()

Answer 1

在您的错误中， Formtastic::UnknownInputError in Admin::Users#new 表示您未定义http://127.0.0.1:5000/home is not found路线。因此，您需要更新/home路由，如下所示

app.get('/')

Answer 2

试试这个

app.use('/', routes);
app.use('/users', users);
//add your route to get file
app.get('/',function(request,response){
  console.log("/");
response.sendfile('views/index.html', {root: __dirname });
});

请参阅文档正确理解res.sendFile

点击此URL http://127.0.0.1:5000/，将您的文件存入browser

res.sendFile不返回HTML
