Nodejs基础之method-override

method-override（扩展 http请求）

app.user(function (req,res){
let req.method = req.query._menthod // 通过取query里面的伪方法_menthod（客户端传过来的），然后重新设置req.method
})

var xhr = new XMLHttpRequest();
xhr.open('post', '/', true);
xhr.setRequestHeader('X-HTTP-Method-Override', 'delete');
xhr.send();

const method-overrider = require('method-overrider')

app.use(methodOverride('X-HTTP-Method-Override'))
...
app.use(/)

<form method="get" action='./'>
<input type="hidden" name="_method" valud="delete"/>
<input type="submit"/>
</form>

const method-overrider = require('method-overrider')

app.use(methodOverride('_method'), {methods: ['post', 'get']}) // 如果不设置，只能接受post
