[非表示]Httpリクエストサンプル

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); if (!request.GetError().Equals("")) { Debug.Log(request.GetError()); // 例:huawei android端末(SSL CA certificate error } } else if (responseType.Equals(WebHttpRequest.ResponseType.NetworkError)) { Debug.Log("NetworkError" + request.errorFlag); if (!request.GetError().Equals("")) { Debug.Log(request.GetError()); // 例:huawei android端末(SSL CA certificate error } } request.Reset(); } } }
http通信許可
android
android9でhttp通信ができなくなってる。
取り急ぎhttp通信を対応したい場合 AndroidManifest.xmlのapplicationに以下属性追加
android:usesCleartextTraffic="true"
https://ameblo.jp/znky/entry-12459683348.html
ios
- unity/build setting/ios/other setting/Configuration
- Allow downloads over HTTPをチェック
- Supported URL schemesのSizeに1を入れ、許可するドメイン"project1.example.net"などを入れる
チェックをつけると以下警告が出る
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.
それでも、http通信時、以下が出る時
The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.
Info.plistへ以下を追加
<key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true /> <key>NSAllowsArbitraryLoadsInWebContent</key> <true /> <key>NSExceptionDomains</key> <dict> <key>project1.example.net</key> <dict> <key>NSIncludesSubdomains</key> <true /> <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key> <true /> </dict> </dict>
project1.example.netは適宜変更
参考:https://clevertap.com/blog/developing-for-ios9-app-transport-security/
補足
unityのiosの設定のAllow downloads over HTTPの下にあるSizeに1を入力しSchemaに、接続するドメイン(project1.example.netなど)を追加しても、以下が追加されるだけで、NSExceptionDomainsではないので、機能しない。
<key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLName</key> <string></string> <key>CFBundleURLSchemes</key> <array> <string>project1.example.net</string> </array> </dict> </array>
iosで、"Malformed URL"エラーになるとき
エラー詳細
WebHttpRequest Get request.error=Malformed URL
たとえば、urlが ttps://example.com/unityapi/statusread?uids[]=1515&uids[]=1130 のように、パラメータに"[]"を含むとurl形式エラーとなるみたい。"[]"を"%5B%5D"でエンコードしてあげると、うまくいく。
