I have been using UnityWebRequest for REST calls through Unity but for a certain project I had to choose another option and started testing RestSharp for Unity (https://github.com/llamazoo/RestSharp-for-unity3d).
The application contains a lot of API calls, therefore I have made a single static class with a static IEnumerator to send the requests and perform a callback to the monobehaviour class which started the coroutine.
There are some methods which Starts the API request coroutine, get the response and performs a callback which again Starts another coroutine of the same IEnumerator. All this works well with UnityWebRequests.
I have tried to do the same with RestSharp, adding a yield to the Async Execute of the API request. The first API call (let's say to endpoint-1) works well, receives the response and performs the callback with data from endpoint-1 as parameter. The callback method formats the data, and calls the same RestSharp IEnumarator with new data to endpoint-2. Here, the static method breaks out of the method as well as the Coroutine. (Which allows only single API call with a response per moment)
The following is my static class
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using RestSharp;
using System.Net;
public static class RestSharpUtil
{
public static IEnumerator request_routine_POST(string url,string json, System.Action callback, System.Action failCallback=null){
Debug.Log("Request : "+json);
RestClient w = new RestClient(url);
RestRequest request = new RestRequest(Method.POST);
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Accept", "application/json");
request.Parameters.Clear();
request.AddParameter("application/json", json, ParameterType.RequestBody);
yield return w.ExecuteAsync(request,(response,AsyncHandler)=> {
if(response.StatusCode == HttpStatusCode.OK || response.StatusCode == HttpStatusCode.Created || response.StatusCode == HttpStatusCode.Accepted){
Debug.Log("Success!-> " + response.Content);
callback(response.Content);
Debug.Log("After Request");
}else{
LoadingPanel.ShowError("Something went wrong, Try again!");
}
});
Debug.Log("Action Complete");
}
}
And the following are my methods (main one and the callback)
public void test(){
string customerdata= "json1";
StartCoroutine(RestSharpUtil.request_routine_POST(endpoint-1, customerdata, OnResponse));
}
void OnResponse(string res){
string otherdata = "some processed data with res";
StartCoroutine(RestSharpUtil.request_routine_POST(endpoint-2, otherdata, OnResponse2));
}
OnResponse2 is just a blank method to show the content. However, performing the Coroutine in OnResponse prints the earlier request, not the new one.
My Result is,
Request : json1
Action Complete
Success -> response
Success -> response
It never prints the "Action Complete" or "After Request". What am I doing wrong here?
