javascript - 分享在 native android/ios 中不起作用？

Question

我如何分享将在 React Native 移动应用 Web 浏览器中打开的 pdf 文件链接或图像链接。我添加了一个共享按钮，但是当用户单击它时，它会打开共享菜单选项的位置，例如 WhatsApp、Gmail、消息等。但是当单击 WhatsApp 时它不会发送任何内容，为什么会这样？我是否需要在我的 react native android 应用程序中使用 Gmail、WhatsApp API

代码:

import {
  Text,
  View,
  StyleSheet,
  Button,
  Animated,
  Dimensions,
  ScrollView,
  Image,
  TouchableOpacity,
  Linking,
  Platform,
  Share
} from 'react-native';


// inside render

onSharePress = (shareOptions) => Share.share(shareOptions);

const shareOptions = {
   title: 'Download Brochure',
    url: brochure
}

// inside return 

<View style={{paddingLeft: 10, marginRight: 20, flex: 1, flexDirection: 'row', justifyContent: 'flex-end'}}>
    <TouchableOpacity onPress={() => this.onSharePress(shareOptions)}>
         <Icon style={{paddingLeft: 10}} name="md-share" size={25} color="black"/>
     </TouchableOpacity>
</View>

在下面的屏幕截图中，您可以看到它只是打开了共享选项菜单，但是当我单击某些平台时，内容(即文件的 URL)未发送，我该怎么做？我错过了什么吗？

Answer 1

Share.share(content, options) receives content and options parameter separately.

Share.share(content, options) returns a Promise on both Android and IOS. You basically need to resolve the Promise or read the response from it.

像这样

Share.share(
{
  message: 'Your message',
  url: YourURL
}
).then(({action, activityType}) => {
if(action === Share.sharedAction)
  console.log('Share was successful');
else
  console.log('Share was dismissed');
});

Promise returns an object containing action, activityType

If the user dismissed the dialog, the Promise will be resolved with action being Share.dismissedAction else with action being Share.sharedAction
