在开发uniapp的过程中就需要判断用户在使用的终端，根据客户端调用不同的链接、参数等。
//手机
/*#ifdef APP-PLUS*/
//对应逻辑
if (plus.os.name == 'Android') {
plus.runtime.openURL(tburl, res => {
uni.showModal({
content: "本机未检测到淘宝客户端，是否打开浏览器访问？",
success: res => {
if (res.confirm) {
plus.runtime.openURL(tburl)
}
}
})
}, 'com.taobao.taobao');
}else{
//
}
/*#endif*/
//H5
/*#ifdef H5*/
//对应逻辑
/*#endif*/
//MP：小程序
/*#ifdef MP*/
//对应逻辑
/*#endif*/也可这样判断：
switch (uni.getSystemInfoSync().platform) {
case 'android':
console.log('运行Android上');
break;
case 'ios':
console.log('运行iOS上');
break;
default:
console.log('运行在开发者工具上');
break;
}因为uni.getSystemInfoSync可以获取很多信息：
