RestClient for Unity 🤘

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"));

Installation 👨‍💻

Unity package

Download and install the .unitypackage file of the latest release published here.

Nuget package

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.

Getting Started 📚

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");
});

Generic Request Method

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,
  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(), //Included in the source code of this library
  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
  RetryCallback = (err, retries) => {}, //See the error before retrying the request
  EnableDebug = true, //See logs of the requests for debug mode
  IgnoreHttpException = true, //Prevent to catch http exceptions
  ChunkedTransfer = false,
  UseHttpContinue = true,
  RedirectLimit = 32
}).Then(response => {
  //Get resources via downloadHandler to have 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");
});

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");
});

Custom HTTP Headers and Options 💥

HTTP Headers, such as Authorization, can be set in the DefaultRequestHeaders object for all requests

RestClient.DefaultRequestHeaders["Authorization"] = "Bearer ...";

Also we can add specific options and override default headers for a request

var currentRequest = new RequestHelper { 
  Uri = "https://jsonplaceholder.typicode.com/photos",
  Headers = new Dictionary<string, string> {
    { "Authorization", "Other token..." }
  }
};
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 manually

Later we can clean the default headers for all requests

RestClient.CleanDefaultHeaders();

Example

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()
  })
});
