Do you need to explicitly specify an endpoint when making a POST request with axios in Vue.js?

An issue has arisen where I am encountering a POST 404 (Not Found) error, similar to what was detailed in another question I previously posted.

Why does the axios.post return POST 404 (Not Found) error even when axios.get does return a valid value?

I have been informed that the reason for the failure of the axios post request, while the axios get request succeeds, is due to the absence of an endpoint designated for the POST method.

After thorough research, it became apparent that the topic of defining an endpoint for the POST method is not extensively covered, or at least not explicitly using the term "endpoint".

https://github.com/axios/axios

Is having an endpoint mandatory whenever calling a POST method?

If so, where should this endpoint be specified? Should it be within the same vue file as the POST call, or should a separate file be created with the endpoint definition and then imported into my main App.vue file?

If not required, why would the axios.post result in a 404 Not Found error?

Answer №1

Do you always need an endpoint to call a POST method?

Endpoint is just a fancy term for "end of a communication channel". Specifically, in this case, it refers to "the function on the server that gets triggered when a URL is accessed with a certain HTTP method".

Therefore, having something that can respond to the HTTP request and provide the necessary data is indeed essential.

Note: This requirement applies not only to POST requests but other methods as well.

If so, where should I establish this endpoint?

This needs to be defined in the server-side code.

In the same vue file where the POST call is made, or should I create a separate file for the endpoint definition and then import it into my main App.vue file?

No, that won't work. The server-side code must handle the request in order to generate the response. Client-side code alone cannot achieve this task.

Answer №2

When you refer to the question, you are discussing

Accessing localhost:4000/somefile **.json** (a **document**)

I believe this is because issuing a GET request for a .json file prompts the server to interpret it as "retrieve the contents of somefile.json," which is acceptable, and respond with said content.

However, when it comes to POST requests, there is no predetermined reaction from the server - you cannot directly post to a file. Instead, you must post to an endpoint. To accomplish this, you would need to establish something like a localhost:4000/addKweet endpoint that receives your kweet data and appends it on the server end using a form of file writing operation.
