Parse无法为以查询为目标的推送设置通道

Question

错误：解析 无法为以查询定位的推送设置渠道。

代码

    ParsePush push = new ParsePush();
    push.setChannel(AppConfig.PARSE_CHANNEL);
    push.setMessage("The Message");
    push.sendInBackground(new SendCallback() {
        @Override
        public void done(ParseException e) {
            if(e==null)
            {
                Toast.makeText(getApplicationContext(),"success",Toast.LENGTH_SHORT).show();
            }
        }
    });

Answer 1

您应该使用ParseQuery代替频道进行定位推送。试试这个：

    ParseQuery<ParseInstallation> query = ParseInstallation.getQuery();
    query.whereEqualTo("deviceToken", token); // recipient of your push. you can find this token in Installation table of your Parse.com app

    ParsePush push = new ParsePush();
    push.setQuery(query);
    push.setMessage("hi");
    push.sendInBackground(new SendCallback() {
        @Override
        public void done(ParseException e) {
            if (e != null)
                e.printStackTrace();
        }
    });

除了GrafOrlov的回答，要查询多个频道，你可以使用whereContainsAll方法。像这样：

String[] listOfAnimals = { "cat", "dog" };
ParseQUery pushQuery = ParseInstallation.getQuery();
pushQuery.whereContainsAll("channels", Arrays.asList(listOfAnimals));

ParsePush push = new ParsePush();
push.setQUery(pushQuery);
