unipush,前端请求个推推送，报条件不合法。但是 推送是成功了。

各位老师！有时间给我解答一下。（我找个推技术群里面说，这个他们解答不了）

// 获取 token
uni.request({
url: 'https://restapi.getui.com/v2/' + appId + '/auth',
method: 'POST',
header: {
'content-type': 'application/json;charset=utf-8'
},
data: {
"sign": signs,
"timestamp": time,
"appkey": appKey
},
success: (res) => {
// token
let tokens = res.data.data.token;

        // cid  
        let CID = plus.push.getClientInfo().clientid;  

        // 随机数  
        let randoms = '';  
        for (var i = 0; i < 20; i++) {  
            if (randoms.length > 20 || randoms.length < 25) {  
                randoms += Math.floor(Math.random() * 10) + 1;  
            }  
        }  
        // console.log(randoms, CID, tokens);  

        uni.request({  
            url: 'https://restapi.getui.com/v2/' + appId + '/push/single/cid',  
            method: 'POST',  
            header: {  
                'content-type': 'application/json;charset=utf-8',  
                'token': tokens // 每次运行他都会改变  
            },  
            data: {  
                "request_id": "" + randoms,  
                "settings": {  
                    "ttl": 3600000  
                },  
                "audience": {  
                    "cid": [  
                        CID  
                    ]  
                },  
                "push_message": {  
                    "notification": {  
                        "title": "超标预警",  
                        "body": "有超标车辆经过",  
                        "click_type": "intent",  
                        "intent": "intent:#Intent;action=android.intent.action.oppopush;launchFlags=0x14000000;component=uni.UNI9050605/io.dcloud.PandoraEntry;S.UP-OL-SU=true;S.title=测试标题;S.content=测试内容;S.payload=test;end"  
                    }  
                }  
            },  
            success: (ress) => {  
                console.log(ress);  
            }  
        });  
    }  
});  

报：400，我看了个推的请求状态，说400是参数不合法
{
"data": {
"msg": "target user is invalid",
"code": 20001
},
"statusCode": 400,
"header": {
"Content-Type": "application/json;charset=utf-8",
"Date": "Fri, 29 Jan 2021 01:17:52 GMT",
"Content-Length": "45",
"Connection": "keep-alive",
"Server": "nginx"
},
"errMsg": "request:ok",
"cookies": []
}
