在URL中使用多个参数 [英] Using multiple parameters in URL in express

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: http://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.
