Express的多个GET参数 [英] Multiple GET parameter with Express

问题描述

我是Node.js和Express的新手， 我一直在进行RESTful API项目，并且正在尝试通过URL发送带有多个参数的GET请求:

I'm new to Node.js and Express, I've been working on a RESTful API project, and I'm trying to send a GET request with multiple parameters in the URL:

这是我的路线:

Here is my route:

/centers/:longitude/:latitude

这是我尝试称呼它的方式:

and here is how I tried to call it:

/centers?logitude=23.08&latitude=12.12

我也尝试过

/centers/23.08/12.12

最终要走这条路线:

/centers/

那么我编写端点的方式是错误的吗?还是我要求的方式?

So is my way of writing the endpoint wrong? or the way I'm requesting it?

推荐答案

您没有正确理解Express中路由定义的工作原理.

You are not correctly understanding how route definitions work in Express.

这样的路由定义:

/centers/:longitude/:latitude

表示它期望这样的URL:

means that it is expecting a URL like this:

/centers/23.08/12.12

---

当您形成这样的URL时:

---

When you form a URL like this:

/centers?longitude=23.08&latitude=12.12

您正在使用查询参数(在?之后的param=value对).要访问这些内容，请参阅以下问题/答案:如何访问在?"之后获取参数在Express中?

You are using query parameters (param=value pairs after the ?). To access those, see this question/answers: How to access the GET parameters after "?" in Express?

为此，您可以为"/centers"创建路由，然后访问req.query.longitude和req.query.latitude来访问那些特定的查询参数.

For that, you could create a route for "/centers" and then you would access req.query.longitude and req.query.latitude to access those particular query parameters.
