http.get返回什么以及如何将其转换为对象

Question

I have this method in my component

  GetInfo(id)
 {
  const data = this.http.get(this.baseUrl + "api/SampleData/EditMake/" + id);
  console.log(data);
 }

It just runs a http.get to a web api controller method. Which returns an object.

    [HttpGet]
    [Route("api/[Controller]/EditMake/{id:int}")]
    public IActionResult EditMake(int id)
    {
        return Ok(_vehicleService.GetMakeById(id));
    }

That is the method in question. Problem is, data isn't an object of the type which the EditMake method returns. What am i missing?

Answer 1

Need to subscribe to the HTTP request. Http request return an observable as a response and in order to access the data, we need to subscribe to the observable.

  GetInfo(id) {

   let data; 

   this.http.get(this.baseUrl + "api/SampleData/EditMake/" + id).subscribe((response) => {
        data = response;
        console.log(data);

   });
 }
