问题已解决

本地运行不会在你的云函数返回之后结束执行，云端会在云函数返回之后强制结束执行

函数中没有写return

async function forLoops(i) {  
    if(i<1670000)  
    {  
        try{  
            const res = await uniCloud.httpclient.request(`xxxxxxxxxxxxxxxxxxxxxxxx`,{  

                dataType:'json'  
            })  
            if(res){  
                // uniCloud.logger.log(res.data)  
                if(res.data.status === "ok"){  
                    // await collection.add(res.data.result)  

                    await collection.doc(res.data.result.appid).set(res.data.result)  
                    await collection.doc('lastappid').set({  
                        appid:res.data.result.appid  
                    })  
                }  
                // upsert(res.data.result)  
            }  
        }catch(e){  
            console.error(e.status)  
        }  

        setTimeout(()=>{  
            // forLoops(i+=1)  
            process.nextTick(forLoops, i+=1);  
        }, 1000)  

    }  
}  

exports.main = async (event) => {  
    let lastappid = await collection.doc('lastappid').get()  
    lastappid=lastappid.data[0]['appid']  
    uniCloud.logger.log(lastappid)  
    await forLoops(lastappid)  
}

的确啊，函数运行个几秒就报执行结果undefind，那么爬虫类的云函数还能跑吗？
