flu*_*ore 17 javascript connect node.js express
我试图让服务器处理PUT请求.但无济于事.提交表单后,客户端始终收到"无法发送/"消息. 我正在使用Express 4.x.
请注意,如果我在路线中将"put"更改为"post",请求处理得很好......
如何让我的服务器处理'PUT'请求？
服务器:
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.");

可以使用查询值覆盖更简单的方法:
var methodOverride = require('method-override')
// override with POST having ?_method=PUT
app.use(methodOverride('_method'))
使用HTML进行查询覆盖的示例调用:
<form method="POST" action="/resource?_method=PUT">
<button type="submit">Put resource</button>
</form>

从方法覆盖v2.0.0(发布2014-06-01)开始,中间件的默认行为不会检查POST正文中的_method字段; 它只检查X-HTTP-Method-Override标题.
为了使方法覆盖像以前的版本一样操作,您需要提供自定义函数methodOverride,在项目页面上详细说明:

您可以使用函数实现任何类型的自定义逻辑
