React Native调用系统浏览器

import {
Linking
} from 'react-native';

//使用系统浏览器访问指定URL
export const contactBaidu = () => {
var baiduURL = 'http://www.baidu.com/'

Linking.canOpenURL(baiduURL).then(supported => {
if (!supported) {
console.warn('Can\'t handle url: ' + baiduURL);
} else {
return Linking.openURL(baiduURL);
}
}).catch(err => console.error('An error occurred',baiduURL));
}
