request.body vs request.params vs request.query [英] request.body vs request.params vs request.query

问题描述

我有一个客户端JS文件，其中包含：

I have a client side JS file that has:

agent = require（'superagent'）; request = agent.get（url）;

agent = require('superagent'); request = agent.get(url);

然后我有类似

request.get(url) 
//or
request.post(url)
request.end( function( err, results ) {
        resultCallback( err, results, callback );
    } );

在后端Node端我有
request.body 和 request.params ，有些还有 request.query

On the backend Node side I have request.body and request.params and some has request.query

正文，参数和查询之间有什么区别？

What are the difference between the body, params and query?

推荐答案

req.params 是路由参数， req.body 是请求的实际主体， req.query 是任何查询参数。

req.params is route parameters, req.body is the actual body of the request, and req.query is any query parameters.

例如，如果我声明此路线：

For example, if I declare this route:

router.get('/user/:id', function(req, res) {});

request.params 将包含 id 。

如果我将遗体传递到此路线：

If I pass a body to this route:

{
  name: 'josh'
}

这将在 request.body 。

如果我将一些查询参数传递给 http://myserver.com/api/user?name=josh， request.query 将 {name：'josh'} 。

If I pass some query parameters to http://myserver.com/api/user?name="josh", request.query will be { name: 'josh' }.
