Dhinesh Muralidharan Trialhead Apex REST Callouts challenge
Hi i am very new to salesforce and has statred learning through Trialhead. I am in the REST callouts section. I started it but i don't know how to get the response. i am not sure if i am going about this right. This is my first time seeing a http service. please any help or guidance would be appreciated. i have pasted my code here .. I get an error that an object cannot be assigned to a string. if i change the type of result to object , the error goes away.I am not sure how to convert it back to a string.
public class AnimalLocator {
public static String getAnimalNameById(Integer id){
Http http = new Http();
HttpRequest request = new HttpRequest();
request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/:id');
request.setMethod('GET');
HttpResponse response = http.send(request);
// check the response
if (response.getStatusCode() == 200)
{
String result = JSON.deserializeUntyped(response.getBody());
}//end of if
return null;
}//end of method
}//end of class
public class AnimalLocator {
public static String getAnimalNameById(Integer id){
Http http = new Http();
HttpRequest request = new HttpRequest();
request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/:id');
request.setMethod('GET');
HttpResponse response = http.send(request);
// check the response
if (response.getStatusCode() == 200)
{
String result = JSON.deserializeUntyped(response.getBody());
}//end of if
return null;
}//end of method
}//end of class
Map<String, Object> results = (Map<String, Object>) JSON.deserializeUntyped(response.getBody());
List<Object> animals = (List<Object>) results.get('animals');
public class AnimalLocator { public static String getAnimalNameById(Integer id){ Http http = new Http(); HttpRequest request = new HttpRequest(); request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/:id'); request.setMethod('GET'); HttpResponse response = http.send(request); string animalName ; string animalEats ; string animalSays ; // check the response if (response.getStatusCode() == 200) { // Deserialize the JSON string into collections of primitive data types Map<String, Object> results = (Map<String, Object>) JSON.deserializeUntyped(response.getBody()); // Cast the values in the 'animals' key as a list List<Object> animals = (List<Object>) results.get('animals'); for (Object animal: animals) { System.debug(animal); //animalName = animal.name; //animalEats = animal.eats; //animalSays = animal.says; //system.debug(animalName +' '+animalEats+' '+animalSays); }//end of if } return null; }//end of method }//end of classI tried it this way but i got null values only. It does not seem to locate the animal by id. when i look at the debug logs it shows that the id is null. am i missing something. were you able to get the animal name by id.
request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/' + id);
public class AnimalLocator { public static String getAnimalNameById(Integer id){ Http http = new Http(); HttpRequest request = new HttpRequest(); request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals/' + id); request.setMethod('GET'); HttpResponse response = http.send(request); string animalName ; string animalEats ; string animalSays ; // check the response if (response.getStatusCode() == 200) { // Deserialize the JSON string into collections of primitive data types Map<String, Object> results = (Map<String, Object>) JSON.deserializeUntyped(response.getBody()); // Cast the values in the 'animals' key as a list List<Object> animals = (List<Object>) results.get('animals'); for (Object animal: animals) { System.debug(animal); //animalName = animal.name; //animalEats = animal.eats; //animalSays = animal.says; //system.debug(animalName +' '+animalEats+' '+animalSays); }//end of if } return null; }//end of method }//end of class
