在快速URL中使用多个参数

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.

我使用的是Express with Node，我有一个要求，用户可以将URL请求为:http://myhost/fruit/apple/red。

Such a request will return a JSON response.

这样的请求将返回JSON响应。

The JSON data, before the above call looks like:

以上调用前的JSON数据如下:

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

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

对于上述请求，响应JSON数据应该是:

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

I have configured express to route as follows:

我将express配置为以下路线:

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?

但这行不通。我不确定如何传递多个参数，也就是说，我不确定是否/水果/:水果名/:水果色是正确的方法。是吗?

2 个解决方案

#1

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.

如果不行，可以使用console.log(req.params)来查看它提供的内容。

For what you want I would've used

你要什么我就用什么

app.get('/fruit/:fruitName&:fruitColor', function(request, response) {
   const name = request.params.fruitName 
   const color = request.params.fruitColor 
});

or better yet

或者更好的是

  app.get('/fruit/:fruit', function(request, response) {
   const fruit = request.params.fruit
   console.log(fruit)
});

where fruit is a object. So in the client app you just call

水果是物体。在客户端应用中，你只需要调用

https://mydomain.dm/fruit/{"name":"My fruit name", "color":"The color of the fruit"}

and as a response you should see:

作为回应你应该看到:

    //  client side response
    // { name: My fruit name, , color:The color of the fruit}

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

    send.json(data);
});
