1/req.query:
Get:/domo?name=ximiximi&blog=https://home.cnblogs.com/u/ximiximi-blog/
app.get('/domo', function(req, res) {
console.log(req.query.name);
console.log(req.query.blog);
});
2/req.body:
<form action='/domo?name=ximiximi' method='post'>
<input type='text' name='blog' value='https://home.cnblogs.com/u/ximiximi-blog/'>
<input type='submit' value='Submit'>
</form>
var bodyParser = require('body-parser');
app.post('/domo', function(req, res) {
console.log(req.query.name);
console.log(req.body.blog);
});
tips:req.body是POST方法。需要注意的是需要npm body-parser
3/req.params:
app.get('/hello/:name/:blog', function(req, res) { console.log(req.params.name); console.log(req.params.blog); });
取带冒号的参数
借用他人对此req方法的理解,标注了出处:
(顺带补充,还有另一种方法传递参数给 Server,就是使用路径的方式,可以利用 Web Server 的 HTTP Routing 來解析,常见于各种 Web Framework。這不算是传统标准规范的做法,是属于 HTTP Routing 的延伸应用。http://liuxufei.com/blog/jishu/798.html)
