REST

UnityのC#でRESTでたたきたい場合には、UnityWebRequestを利用する。

GET

   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) {
				Debug.Log ("success");
				Debug.Log(request.downloadHandler.text);
			} else {
				Debug.Log ("failed");
			}
		}
	}

POST

    public IEnumerator Post (string url, string jsonStr) {
		var request = new UnityWebRequest();
		request.url = url;
		byte[] body = Encoding.UTF8.GetBytes(jsonStr);
		request.uploadHandler = new UploadHandlerRaw(body);
		request.downloadHandler = new DownloadHandlerBuffer();
		request.SetRequestHeader("Content-Type", "application/json; charset=UTF-8");
		request.method = UnityWebRequest.kHttpVerbPOST;
		yield return request.Send();

		if(request.isError) {
			Debug.Log(request.error);
		}
		else {
			if (request.responseCode == 200) {
				Debug.Log ("success");
				Debug.Log(request.downloadHandler.text);
			} else {
				Debug.Log ("failed");
			}
		}
	}

DELETE

	public IEnumerator Delete (string url) {
		var request = new UnityWebRequest();
		request.url = url;
		request.downloadHandler = new DownloadHandlerBuffer();
		request.SetRequestHeader("Content-Type", "application/json; charset=UTF-8");
		request.method = UnityWebRequest.kHttpVerbDELETE;
		yield return request.Send();

		if(request.isError) {
			Debug.Log(request.error);
		}
		else {
			if (request.responseCode == 200) {
				Debug.Log ("success");
				Debug.Log(request.downloadHandler.text);
			} else {
				Debug.Log ("failed");
			}
		}
	}

PUT

	public IEnumerator Put (string url, string jsonStr) {
		var request = new UnityWebRequest();
		request.url = url;
		byte[] body = Encoding.UTF8.GetBytes(jsonStr);
		request.uploadHandler = new UploadHandlerRaw(body);
		request.downloadHandler = new DownloadHandlerBuffer();
		request.SetRequestHeader("Content-Type", "application/json; charset=UTF-8");
		request.method = UnityWebRequest.kHttpVerbPUT;
		yield return request.Send();

		if(request.isError) {
			Debug.Log(request.error);
		}
		else {
			if (request.responseCode == 200) {
				Debug.Log ("success");
				Debug.Log(request.downloadHandler.text);
			} else {
				Debug.Log ("failed");
			}
		}
	}
