The HttpClient.post request is working properly, however the Rest API is unable to retrieve the data

I need help with saving information from my Angular application into a database. I am utilizing the HttpClient to send data via POST requests to the RestAPI. The request is being sent, however, the API does not receive the data and instead returns a response code:500.

Upon checking the console logs, I can confirm that the data is indeed being sent, but for unknown reasons, the RestAPI is unable to retrieve it.

Interestingly, when I tested sending a POST request using Postman, it worked without any issues. This leads me to believe that there may not be an issue with the backend after all.

Answer №1

In order to properly post, you must subscribe to the function afterwards.

this.http.post(`${this.Baseurl}/insertPost`, newPost, this.httpheader).subscribe(
      res => {
         // perform actions here
      },
      err => {
        // handle errors here
      }
);

Answer №2

  • If logging is not appearing, you may need to invoke .subscribe() or .toPromise().
  • In the event that something gets logged but the response returns as null and displays a status code of 500, this indicates that the API has crashed (encountered a runtime error) and your request may have been terminated.

Answer №3

According to @YuTing's advice, make sure to subscribe after making a post request.

this.http.post(`${this.Baseurl}/insertPost`, newPost, this.httpheader)
.subscribe((response: any) =>{

//The JSON response received from the server upon calling the API.
      if(response){

         //implement specific actions

      }
});
