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));            
}
