RestClient for Unity ๐Ÿค˜

Supported Unity versions 2017.2 or higher

Proyecto26.RestClient logo

This HTTP/REST Client is based on Promises to avoid the Callback Hell โ˜ ๏ธ and the Pyramid of doom ๐Ÿ’ฉ working with Coroutines in Unity ๐ŸŽฎ, 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! ๐Ÿ‘

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 ๐Ÿ‘จโ€๐Ÿ’ป

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 ๐Ÿ“š

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");
});

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 = newPost, //Content-Type: application/json
  BodyString = "Use it instead of 'Body' if you want to use other tool to serialize the JSON",
  SimpleForm = new Dictionary<string, string> {}, //Content-Type: application/x-www-form-urlencoded
  FormSections = new List<IMultipartFormSection>() {}, //Content-Type: multipart/form-data
  ChunkedTransfer = true,
  IgnoreHttpException = true //Prevent to catch http exceptions
}).Then(response => {
  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 weโ€™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 ๐Ÿ’ฅ

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");
});

currentRequest.UploadProgress; //To know the progress by uploading data to the server
currentRequest.DownloadProgress; //To know the progress by downloading data from the server
currentRequest.Abort(); //Abort the request manually

And 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()
  })
});
