Question

我正在尝试使用nodejs和expressjs进行重定向，但是当我单击按钮时，仅URL更改没有任何反应。我使用的是表格，表格中有一个按钮，该表格具有“ / failure”操作

const express = require("express")
const bodyparser = require("body-parser")
const request = require("request")

const app = express()

app.use(express.static("public"))
app.use(bodyparser.urlencoded({
  extended: true
}))

app.get("/", function (req, res) {
  res.sendFile(__dirname + "/signup.html")
})

app.post("/failure", function(req, res){
   res.redirect("/")
})

app.listen(3000, function () {
  console.log("Server is running on port 3000")
})

Answer 1

您尝试过

res.redirect(307, '/test');

}）；

这将保留send方法，有关更多信息，您可以检查http://www.alanflavell.org.uk/www/post-redirect.html

Answer 2

此行为是正确的。您正在发布到'/failure'路由，并且在该路由的处理程序内，它正在重定向以获取'/'路由处理程序，该处理程序将返回signup.html-这是您的起点。

您要发布到此：

app.post("/failure", function(req, res){
   res.redirect("/") // this is redirecting your route handler '/' which serves 'signup.html
})

为什么这个“ res.redirect（）”不重定向？
