问题描述
请注意，如果我在路由中更改put到post，则请求被处理只是很好...
我的服务器如何处理'PUT'请求？
SERVER：
var express = require（express）;
var bodyParser = require（body-parser）;
var methodOverride = require（method-override）;
var app = express（）;
app.use（bodyParser（））;
app.use（methodOverride（））;
app.get（/，function（req，res）{
res.render（index.ejs）;
console.log GET。）;
}）;
app.put（/，function（req，res）{
console.log（PUT received：+ req.body.userName + - + req.body.password）;
}）;
app.listen（1337）;
console.log（Listening on 1337.）;
客户
<！DOCTYPE html>
< html>
< head>
< title> TODO提供标题< / title>
< / head>
< body>
< form action =/method =post>
First
< input type =textname =first>
最后
< input type =textname =last>
< input type =hiddenname =_ methodvalue =put>
< button type =submit> Submit< / button>
< / form>
< / body>
< / html>
解决方案
一个更简单的方法可以是使用查询值覆盖：
var methodOverride = require（'method-override'）
//覆盖POST，具有？_method = PUT
app.use methodOverride（'_ method'））
使用HTML进行查询覆盖的示例调用：
< form method =POSTaction =/ resource？_method = PUT>
< button type =submit>将资源< / button>
< / form>
I am attempting to have the server handle a PUT request. But to no avail. The client keeps receiving "Cannot POST /" message after submitting the form. I am using Express 4.x.
Note that if I change "put" to "post" in my route, the request gets handled just fine...
How can I have my server handle the 'PUT' request?
SERVER:
var express = require("express");
var bodyParser = require("body-parser");
var methodOverride = require("method-override");
var app = express();
app.use(bodyParser());
app.use(methodOverride());
app.get("/",function(req,res){
res.render("index.ejs");
console.log("GET received.");
});
app.put("/",function(req,res){
console.log("PUT received: " + req.body.userName + " - " + req.body.password);
});
app.listen(1337);
console.log("Listening on 1337.");
CLIENT
<!DOCTYPE html>
<html>
<head>
<title>TODO supply a title</title>
</head>
<body>
<form action="/" method="post">
First
<input type="text" name="first">
Last
<input type="text" name="last">
<input type="hidden" name="_method" value="put">
<button type="submit">Submit</button>
</form>
</body>
</html>
解决方案
A simpler way could be override using a query value:
var methodOverride = require('method-override')
// override with POST having ?_method=PUT
app.use(methodOverride('_method'))
Example call with query override using HTML :
<form method="POST" action="/resource?_method=PUT">
<button type="submit">Put resource</button>
</form>
