Question

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Parse终端发送推送通知并在Android设备上接收测试。

但是当我以编程方式发送推送时会出现例外情况：“未经授权：需要主密钥”。

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();
            }
        }
    });

android manifest.xml：

            <category android:name="com.demo" />

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!");
        }
    });
    }
 }

更新的答案

嗨，我稍微调查一下，发现目前发送Push的唯一方法就是使用 masterKey ，这就是你收到此错误的原因

为了使用主密钥发送推送，最好的方法是创建云代码功能并从客户端触发此功能。所以你需要做以下事情：

在您的云代码main.js文件中创建一个新功能

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);
    });
});

创建云代码功能后重启服务器

以下列方式从您的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 
    }
});

这将触发您在上面和云代码内部创建的云代码函数的调用 useMasterKey true ，因此它应该可以正常工作。

更新：拼写

Answer 2

useMasterKey：是

这将使解析服务器能够使用主键从客户端推送通知。

解析推送通知例外：“未授权：需要主密钥”
