我想使用 Parse API 和 GCM 发送推送通知。我已经在服务器上成功配置并通过从 Parse 终端发送推送通知并在 android 设备上接收进行了测试。

但是当我以编程方式发送推送时出现异常:“未授权:需要主 key ”。

我使用以下代码:

ParseQuery query = ParseInstallation.getQuery();
    query.whereEqualTo("channels", "testing");

    // Notification for Android users
    query.whereEqualTo("deviceType", "android");
    ParsePush androidPush = new ParsePush();
    androidPush.setMessage("Your suitcase has been filled with tiny robots!");
    androidPush.setQuery(query);
    androidPush.sendInBackground(new SendCallback() {
        @Override
        public void done(ParseException e) {
            if ( e == null ) {
                Log.d("GARG","Parse Notification Done. : ");
            } else {
                Log.d("GARG","Notification failed.: "+e.getMessage());
                e.printStackTrace();
            }
        }
    });

在android中初始化Parse SDK

public class AppInitializer extends Application {

public static JSONObject errorDataProvider;

@Override
public void onCreate() {

    super.onCreate();
    Parse.enableLocalDatastore(getApplicationContext());
    Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
            .applicationId(Utility.ApplicationId)
            .clientKey(Utility.ClientKey)
            .server(Utility.Server_URL)
            .build()
    );

    ParseInstallation.getCurrentInstallation().saveInBackground();

    ParsePush.subscribeInBackground(Utility.PARSE_CHANNEL, new SaveCallback() {
        @Override
        public void done(ParseException e) {
            Log.e("GARG", "Successfully subscribed to Parse!");
        }
    });
    }
 }

最佳答案

更新的答案

嗨，我调查了一下，发现目前唯一发送推送的方法是使用 ma​​sterKey，这正是您收到此错误的原因

为了使用主 key 发送推送，最好的方法是创建一个云代码函数并从客户端触发该函数。 所以你需要做以下事情:

1. 在您的云代码 main.js 文件中创建一个新函数

Parse.Cloud.afterSave("SendPush", function(request) {


  var query = new Parse.Query(Parse.Installation);
  query.exists("deviceToken");

  // here you can add other conditions e.g. to send a push to sepcific users or channel etc.

  var payload = {
    alert: "YOUR_MESSAGE"
      // you can add other stuff here...
  };


  Parse.Push.send({
      data: payload,
      where: query
    }, {
      useMasterKey: true
    })
    .then(function() {
      response.success("Push Sent!");
    }, function(error) {
      response.error("Error while trying to send push " + error.message);
    });
});

创建云代码函数后重启服务器

1. 通过以下方式从您的 Android 应用程序触发此云代码功能:

   HashMap<String,String> map = new HashMap<String, String>();
   map.put("PARAM1KEY","PARAM1VALUE");
   // here you can send parameters to your cloud code functions
   // such parameters can be the channel name, array of users to send a push to and more...
   
   ParseCloud.callFunctionInBackground("SendPush",map, new FunctionCallback<Object>() {
   
       @Override
       public void done(Object object, ParseException e) {
           // handle callback 
       }
   });
   

这将触发对您在云代码上方和内部创建的云代码函数的调用，useMasterKey 为 true，因此它应该可以工作。
