Uniapp monitor whether the app has a network connection

It has been proved by many tests and consulting relevant data uniapp Provided by the official website

uni.getNetworkType({ success: function (res) { console.log(res.networkType); } })

Method cannot realize monitoring , The monitoring mentioned on the official website refers to being called when the network changes , To realize monitoring, we need to cooperate with two api Use

Network change triggers callback function

uni.onNetworkStatusChange(function(res) {
			let title = ` You are currently in ${res.networkType} The Internet , Please pay attention to privacy `
            if(res.networkType=='none')title =' There is currently no network connection '
			uni.showToast({
				title,
				icon: 'none'
			});
		});

Get the initial network status

uni.getNetworkType({
    success: function (res) {
        console.log(res.networkType);// Network type  wifi、2g、3g、4g、ethernet、unknown、none
        if(res.networkType === "none"){
            console.log(" There is no network at present ");
        }else{
            console.log(" There's a network ");
        }
    }
});
