Httpリクエストサンプル

以下delegateを使ったhttpリクエストサンプルコード

• WebHttpRequest.cs

using System.Collections;
using UnityEngine;
using UnityEngine.Networking;
public class WebHttpRequest : MonoBehaviour {
    string text = "";
    public bool errorFlag = false;
    public enum ResponseType
    {
        Success,
        Failure,
        NetworkError
    }
    public delegate void CustomCallback(ResponseType responseType);
    private CustomCallback callbacks;
    public void AddCallback(CustomCallback callback)
    {
        callbacks += callback;
    }
    public void Exec (string url) {
        text = "";
        errorFlag = false;
        StartCoroutine(Get (url));
    }
    public IEnumerator Get (string url) {
        var request = new UnityWebRequest();
        request.downloadHandler = new DownloadHandlerBuffer();
        request.url = url;
        request.SetRequestHeader("Content-Type", "application/json; charset=UTF-8");
        request.method = UnityWebRequest.kHttpVerbGET;
        yield return request.Send();
        if (request.isNetworkError) {
            errorFlag = true;
            if (callbacks != null)
            {
                callbacks(ResponseType.NetworkError);
            }
        } else {
            if (request.responseCode == 200) {
                text = request.downloadHandler.text;
                if (callbacks != null)
                {
                    callbacks(ResponseType.Success);
                }
            } else {
                errorFlag = true;
                if (callbacks != null)
                {
                    callbacks(ResponseType.Failure);
                }
            }
        }
   }
   public string GetBody() {
       return text;
   }
   public void Reset() {
       text = "";
       errorFlag = false;
   }
}

呼び出し元

• NewBehaviourScript.cs

public class NewBehaviourScript : MonoBehaviour {
    WebHttpRequest request;
    // http送信
    void Start () {
        const string uri = "http://raw.githubusercontent.com/nlohmann/json/develop/test/data/json.org/1.json";
        string param1 = "value1";
        param1 = WWW.EscapeURL(param1);
        string query = "?hoge=" + param1;
        string url = uri + query;
        GameObject gameObj = new GameObject();
        request = gameObj.AddComponent<WebHttpRequest>();
        request.AddCallback(OnResponse);
        request.Exec(url);
        Debug.Log("request=" + url);
    }
    // httpのresponse受信
    public void OnResponse(WebHttpRequest.ResponseType responseType)
    {
        Debug.Log("OnResponse=" + responseType);
        if (request)
        {
            if (responseType.Equals(WebHttpRequest.ResponseType.Success))
            {
            Debug.Log("body=" + request.GetBody());
            } else if (responseType.Equals(WebHttpRequest.ResponseType.Failure)) {
                Debug.Log("errorFlag=" + request.errorFlag);
            }
            else if (responseType.Equals(WebHttpRequest.ResponseType.NetworkError))
            {
                Debug.Log("NetworkError" + request.errorFlag);
            }
            request.Reset();
        }
    }
}

Httpリクエストサンプル(これはDelegateを使ってないダメな例)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using UnityEngine.Networking;
public class WebHttpRequest : MonoBehaviour {
   string text = "";
   public bool errorFlag = false;
   public void Exec (string url) {
      text = "";
      errorFlag = false;
      StartCoroutine(Get (url));
   }
   public IEnumerator Get (string url) {
     var request = new UnityWebRequest();
     request.downloadHandler = new DownloadHandlerBuffer();
     request.url = url;
     request.SetRequestHeader("Content-Type", "application/json; charset=UTF-8");
     request.method = UnityWebRequest.kHttpVerbGET;
     yield return request.Send();
     if (request.isError) {
       Debug.Log(request.error);
     } else {
       if (request.responseCode == 200) {
         text = request.downloadHandler.text;
         Debug.Log(request.downloadHandler.text);
       }
     }
   }
   public string GetBody() {
       return text;
   }
   public void Reset() {
       text = "";
       errorFlag = false;
   }
}

呼び出し側

const string uri = "ttp://hogehoge.com/api?param1=";
string param1 = "value1";
param1 = WWW.EscapeURL (param1);
string url = uri + param1;
GameObject gameObj = new GameObject();
WebHttpRequest request = gameObj.AddComponent<WebHttpRequest>();
request.Exec (url);

呼び出し側で受信チェック

void Update ()
{
    if (request) {
        if (!request.GetBody ().Equals ("")) {
             // 処理
             request.Reset ();
        } else if (request.errorFlag) {
             request.errorFlag = false;
        }
    }
}

http通信許可

android

ios

"You are using download over http. Currently Unity adds NSAllowsArbitraryLoads to Info.plist to simplify transition, but it will be removed soon. Please consider updating to https."エラーが出る
