VisualizaçõesHandling different URL paths while hitting a single endpoint (Nodejs)
I am using express nodejs to hit an endpoint:
app.use("/number", numberRouter);
Now I have to handle URL in which the path is different. Here we have three different paths in the same URL:
- https://localhost:8080/number/one
- https://localhost:8080/number/two
- https://localhost:8080/number/three
The file in which the numberRouter is handled:
numberRouter.post("/", async (req:Request, res:Response) => {
var url = req.protocol + '://' + req.get('host') + req.originalUrl;
//what I want to do
if (req.path == "one") {
//do something
}
else if (req.path == "two") {
//do something
}
});
What I want to achieve is that once I hit the number endpoint, I fetch the full URL, extract out it's path and based on the path I do further processing instead of hitting three different endpoints (/number/one, /number/two, /number/three).
Is this possible?
I am using postman for testing and if I send a post request with the following URL:
localhost:8080/number/one the post request fails. I want something like this in the code:
numberRouter.post("/variablePath", async (req:Request, res:Response) => { ... }
where the variablePath is set via postman (one, two or three) and then processed here.
SOLUTION (following @traynor's answer):
app.use("/number", numberRouter);
numberRouter.post("/:pathNum", async (req:Request, res:Response) => {
if (req.path === "/one") {
//do something
}
else if (req.path === "/two") {
//do something
}
});
The post request via postman: localhost:8080/number/:pathNum.
In postman set the value of pathNum in the Params section under the Path Variables heading.

use route parameters
add your parameter to the router, for example /:myparam, and then check it and run your code:
numberRouter.post("/:myparam", async (req:Request, res:Response) => {
const myParam = req.params.myparam;
//what I want to do
if (myParam == "one") {
//do something
}
else if (myParam == "two") {
//do something
}
});
