Handling Exceptions caused by HTTP RequestHandling Exceptions caused by HTTP Request

Important Points:

  • Runtime errors can occur when making API requests. The most notable case is if the URL / URI provided is invalid;
  • We use try-catch blocks to enclose the GetAsync method to make it safe;
  • The HttpResponseMessage class has an IsSuccessStatusCode attribute, which has the value true in case the API successfully responds with the requested data;
  • HttpResponseMessage also has a StatusCode attribute which represents the response status code. You can learn more about status codes here;
  • HTTP status codes are three-digit numbers returned by a server in response to a client's request made to a website or web server. They provide information about the outcome of the request and help troubleshoot issues.
Other HTTP methods including POST, PUT and DELETE will be covered in the upcoming course when we create our own API.
