Sending HTTP requests and parsing JSON in TestComplete

Tasks

Sending HTTP requests and parsing JSON in TestComplete. Here are the steps how it can be resolved:

Send a GET request to https://dog.ceo/api/breeds/image/random. Check the status of the request - if it is successful, the response will return a JSON that contains a link to a random picture of a dog.
Parse the returned JSON to extract the link to the image. JavaScript and Python provide support for JSON out of the box; for other languages, you might want to parse JSON as a string or use regular expressions.
Send a GET request to the URL obtained from the previous response - this will return an image.

4. Save the response as an image to a JPG file by calling the SaveToFile method like this: response.SaveToFile("C:\\image.jpg")

Solution

//JavaScript

function getThisDog(https) {
  var aqHttpRequest = aqHttp.CreateGetRequest(https);
  
  aqHttpRequest.SetHeader("Accept", "application/vnd.api+json; version=1");
  aqHttpRequest.SetHeader("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
  aqHttpRequest.SetHeader("Accept-Language", "pl");
  aqHttpRequest.SetHeader("Accept-Charset", "utf-8, iso-8859-13;q=0.8");
  aqHttpRequest.SetHeader("Content-Language", "pl");

  var aqHttpRes = aqHttpRequest.Send();  
  Log.Message(aqHttpRes.Text);
  return aqHttpRes;
}

function parseThisDog() {
  let jsonResponse = getThisDog("https://dog.ceo/api/breeds/image/random");
  
  if(jsonResponse.StatusCode === 200) {
    let doggyJson = JSON.parse(jsonResponse.Text);

    let dogImage = getThisDog(doggyJson.message);
    let randomString = Math.random().toString(36).substring(2, 15) + Math.random().toString(36).substring(2, 15);
    dogImage.SaveToFile("C:\\TEST-TRASH\\" + randomString + "dog.jpg");

  } else {
    Log.Error("Something went wrong while trying to connect")
  }
  
}
