This HTTP/REST Client is based on Promises to avoid the Callback Hell ☠️ and the Pyramid of doom 💩 working with Coroutines in Unity 🎮, example:
var api = "https://jsonplaceholder.typicode.com";
RestClient.GetArray<Post>(api + "/posts", (err, res) => {
RestClient.GetArray<Todo>(api + "/todos", (errTodos, resTodos) => {
RestClient.GetArray<User>(api + "/users", (errUsers, resUsers) => {
//Missing validations to catch errors!
});
});
});But working with Promises we can improve our code, yay! 👏
RestClient.GetArray<Post>(api + "/posts").Then(response => {
EditorUtility.DisplayDialog ("Success", JsonHelper.ArrayToJson<Post>(response, true), "Ok");
return RestClient.GetArray<Todo>(api + "/todos");
}).Then(response => {
EditorUtility.DisplayDialog ("Success", JsonHelper.ArrayToJson<Todo>(response, true), "Ok");
return RestClient.GetArray<User>(api + "/users");
}).Then(response => {
EditorUtility.DisplayDialog ("Success", JsonHelper.ArrayToJson<User>(response, true), "Ok");
}).Catch(err => EditorUtility.DisplayDialog ("Error", err.Message, "Ok"));- Works out of the box 🎉

Do you want to see this beautiful package in action? Download the demo here
Download and install the .unitypackage file of the latest release published here.
Make sure you had installed C# Promise package or at least have it in your openupm scope registry. Then install RestClient package using this URL from Package Manager: https://github.com/proyecto26/RestClient.git#upm
Other option is download this package from NuGet with Visual Studio or using the nuget-cli, a NuGet.config file is required at the root of your Unity Project, for example:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<config>
<add key="repositoryPath" value="./Assets/Packages" />
</config>
</configuration>The package to search for is Proyecto26.RestClient.
The default methods (GET, POST, PUT, DELETE, HEAD) are:
RestClient.Get("https://jsonplaceholder.typicode.com/posts/1").Then(response => {
EditorUtility.DisplayDialog("Response", response.Text, "Ok");
});
RestClient.Post("https://jsonplaceholder.typicode.com/posts", newPost).Then(response => {
EditorUtility.DisplayDialog("Status", response.StatusCode.ToString(), "Ok");
});
RestClient.Put("https://jsonplaceholder.typicode.com/posts/1", updatedPost).Then(response => {
EditorUtility.DisplayDialog("Status", response.StatusCode.ToString(), "Ok");
});
RestClient.Delete("https://jsonplaceholder.typicode.com/posts/1").Then(response => {
EditorUtility.DisplayDialog("Status", response.StatusCode.ToString(), "Ok");
});
RestClient.Head("https://jsonplaceholder.typicode.com/posts").Then(response => {
EditorUtility.DisplayDialog("Status", response.StatusCode.ToString(), "Ok");
});ExecuteOnMainThread.RunOnMainThread.Enqueue(() => {
//Any API call using RestClient
});And we have a generic method to create any type of request:
RestClient.Request(new RequestHelper {
Uri = "https://jsonplaceholder.typicode.com/photos",
Method = "POST",
Timeout = 10,
Params = new Dictionary<string, string> {
{ "param1", "Query string param..." }
},
Headers = new Dictionary<string, string> {
{ "Authorization", "Bearer JWT_token..." }
},
Body = newPhoto, //Serialize object using JsonUtility by default
BodyString = SerializeObject(newPhoto), //Use it instead of 'Body' to serialize using other tools
BodyRaw = CompressToRawData(newPhoto), //Use it instead of 'Body' to send raw data directly
FormData = new WWWForm(), //Send files, etc with POST requests
SimpleForm = new Dictionary<string, string> {}, //Content-Type: application/x-www-form-urlencoded
FormSections = new List<IMultipartFormSection>() {}, //Content-Type: multipart/form-data
CertificateHandler = new CustomCertificateHandler(), //Create custom certificates
UploadHandler = new UploadHandlerRaw(bytes), //Send bytes directly if it's required
DownloadHandler = new DownloadHandlerFile(destPah), //Download large files
ContentType = "application/json", //JSON is used by default
Retries = 3, //Number of retries
RetrySecondsDelay = 2, //Seconds of delay to make a retry
RetryCallbackOnlyOnNetworkErrors = true, //Invoke RetryCallack only when the retry is provoked by a network error
RetryCallback = (err, retries) => {}, //See the error before retrying the request
ProgressCallback = (percent) => {}, //Reports progress of the request from 0 to 1
EnableDebug = true, //See logs of the requests for debug mode
IgnoreHttpException = true, //Prevent to catch http exceptions
ChunkedTransfer = false,
UseHttpContinue = true,
RedirectLimit = 32,
DefaultContentType = false, //Disable JSON content type by default
ParseResponseBody = false //Don't encode and parse downloaded data as JSON
}).Then(response => {
//Get resources via downloadHandler to get more control!
Texture texture = ((DownloadHandlerTexture)response.Request.downloadHandler).texture;
AudioClip audioClip = ((DownloadHandlerAudioClip)response.Request.downloadHandler).audioClip;
AssetBundle assetBundle = ((DownloadHandlerAssetBundle)response.Request.downloadHandler).assetBundle;
EditorUtility.DisplayDialog("Status", response.StatusCode.ToString(), "Ok");
}).Catch(err => {
var error = err as RequestException;
EditorUtility.DisplayDialog("Error Response", error.Response, "Ok");
});- Example downloading an audio file:
var fileUrl = "https://raw.githubusercontent.com/IonDen/ion.sound/master/sounds/bell_ring.ogg";
var fileType = AudioType.OGGVORBIS;
RestClient.Get(new RequestHelper {
Uri = fileUrl,
DownloadHandler = new DownloadHandlerAudioClip(fileUrl, fileType)
}).Then(res => {
AudioSource audio = GetComponent<AudioSource>();
audio.clip = ((DownloadHandlerAudioClip)res.Request.downloadHandler).audioClip;
audio.Play();
}).Catch(err => {
EditorUtility.DisplayDialog ("Error", err.Message, "Ok");
});With all the methods we have the possibility to indicate the type of response, in the following example we're going to create a class and the HTTP requests to load JSON data easily:
[Serializable]
public class User
{
public int id;
public string name;
public string username;
public string email;
public string phone;
public string website;
}- GET JSON
var usersRoute = "https://jsonplaceholder.typicode.com/users";
RestClient.Get<User>(usersRoute + "/1").Then(firstUser => {
EditorUtility.DisplayDialog("JSON", JsonUtility.ToJson(firstUser, true), "Ok");
});- GET Array (JsonHelper is an extension to manage arrays)
RestClient.GetArray<User>(usersRoute).Then(allUsers => {
EditorUtility.DisplayDialog("JSON Array", JsonHelper.ArrayToJsonString<User>(allUsers, true), "Ok");
});Also we can create different classes for custom responses:
[Serializable]
public class CustomResponse
{
public int id;
}- POST
RestClient.Post<CustomResponse>(usersRoute, newUser).Then(customResponse => {
EditorUtility.DisplayDialog("JSON", JsonUtility.ToJson(customResponse, true), "Ok");
});- PUT
RestClient.Put<CustomResponse>(usersRoute + "/1", updatedUser).Then(customResponse => {
EditorUtility.DisplayDialog("JSON", JsonUtility.ToJson(customResponse, true), "Ok");
});HTTP Headers, such as Authorization, can be set in the DefaultRequestHeaders object for all requests
RestClient.DefaultRequestHeaders["Authorization"] = "Bearer ...";Query string params can be set in the DefaultRequestParams object for all requests
RestClient.DefaultRequestParams["param1"] = "Query string value...";Also we can add specific options and override default headers and params for a request
var currentRequest = new RequestHelper {
Uri = "https://jsonplaceholder.typicode.com/photos",
Headers = new Dictionary<string, string> {
{ "Authorization", "Other token..." }
},
Params = new Dictionary<string, string> {
{ "param1", "Other value..." }
}
};
RestClient.GetArray<Photo>(currentRequest).Then(response => {
EditorUtility.DisplayDialog("Header", currentRequest.GetHeader("Authorization"), "Ok");
});And we can know the status of the request and cancel it!
currentRequest.UploadProgress; //The progress by uploading data to the server
currentRequest.UploadedBytes; //The number of bytes of body data the system has uploaded
currentRequest.DownloadProgress; //The progress by downloading data from the server
currentRequest.DownloadedBytes; //The number of bytes of body data the system has downloaded
currentRequest.Abort(); //Abort the request manuallyAdditionally we can run a callback function whenever a progress change happens!
RestClient.Get(new RequestHelper {
Uri = "https://jsonplaceholder.typicode.com/users",
ProgressCallback = percent => Debug.Log(percent)
});Later we can clear the default headers and params for all requests
RestClient.ClearDefaultHeaders();
RestClient.ClearDefaultParams();- Unity as Client
[Serializable]
public class ServerResponse {
public string id;
public string date; //DateTime is not supported by JsonUtility
}
[Serializable]
public class User {
public string firstName;
public string lastName;
}
RestClient.Post<ServerResponse>("www.api.com/endpoint", new User {
firstName = "Juan David",
lastName = "Nicholls Cardona"
}).Then(response => {
EditorUtility.DisplayDialog("ID: ", response.id, "Ok");
EditorUtility.DisplayDialog("Date: ", response.date, "Ok");
});- NodeJS as Backend (Using Express)
router.post('/', function(req, res) {
console.log(req.body.firstName)
res.json({
id: 123,
date: new Date()
})
});- C-Sharp-Promise: Promises library for C# for management of asynchronous operations.
