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

问题描述

我在 Node 中使用 Express，我有一个要求，用户可以请求 URL 为:http://myhost/fruit/apple/red.

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.

这样的请求将返回一个 JSON 响应.

Such a request will return a JSON response.

上述调用之前的JSON数据如下所示:

The JSON data, before the above call looks like:

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

有了上面的请求，响应的JSON数据应该是:

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

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

我已将 express 配置为如下路由:

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*/
    });  

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 /fruit/:fruitName/:fruitColor 是否是正确的方法.是吗?

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?

推荐答案

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

    send.json(data);
});

如果这不起作用，请尝试使用 console.log(req.params) 看看它给了你什么.

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