在URL中使用多个参数

本文介绍了在URL中使用多个参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在使用Express with Node，我有一个要求，用户可以在其中请求URL： http：// myhost / fruit / apple / red 。

这样的请求将返回JSON响应。

上述电话之前的JSON数据如下所示：

{fruit：{apple：foo} }

根据上述要求，响应JSON数据应为：

{apple：foo，color：red}

我已经配置了快递路由，如下所示：

app.get（'/ fruit /：fruitName / '，function（request，response）{ / *如上所述使用request.params.fruitName和 request.params.fruitColor返回响应JSON数据，以获取果苹果并将其颜色更新为红色* / }）;

但这不行。我不确定如何传递多个参数，也就是说，我不确定 / fruit /：fruitName /：fruitColor 是否是正确的方法。是吗？

解决方案

app.get（'/ fruit /：fruitName / '，function（req，res）{ var data = {fruit：{apple：req.params.fruitName，color：req。 params.fruitColor } }; send.json（data）; }）;

如果不行，请尝试使用console.log（req.params）查看它正在给你。

I am using Express with Node and I have a requirement in which the user can request the URL as: myhost/fruit/apple/red.

Such a request will return a JSON response.

The JSON data, before the above call looks like:

{ "fruit": { "apple": "foo" } }

With the above request, the response JSON data should be:

{ "apple": "foo", "color": "red" }

I have configured express to route as follows:

app.get('/fruit/:fruitName/:fruitColor', function(request, response) { /*return the response JSON data as above using request.params.fruitName and request.params.fruitColor to fetch the fruit apple and update its color to red*/ });

But this does not work. I am unsure of how to pass multiple parameters, that is, I am unsure if /fruit/:fruitName/:fruitColor is the correct way to do this. Is it?

解决方案

app.get('/fruit/:fruitName/:fruitColor', function(req, res) { var data = { "fruit": { "apple": req.params.fruitName, "color": req.params.fruitColor } }; send.json(data); });

If that doesn't work, try using console.log(req.params) to see what it is giving you.
