在本机上，在Android上，canOpenURL失败& OpenURL抛出一个错误:无法打开URL
在本机上，在Android上，canOpenURL失败& OpenURL抛出一个错误:无法打开URL
提问于 2022-05-12 04:09:12
在React-Native移动应用程序中，如果Linking.canOpenURL引用应用程序屏幕，则Linking.canOpenURL和Linking.openURL会失败，而当引用HTTPS时则会运行。我怀疑这是Android权限的问题。我还没有在iOS上试过。知道我错过了什么吗？
我的代码：
// const url = "https://google.com"; // works
const url = "casualjob://"; // does NOT work
Linking.canOpenURL(url)
.then( (supported) => {
// execution reaches this point -> supported: false
console.log("canOpenURL - ", "supported:", supported, );
});
Linking.openURL(url)
.then(() => {
console.log("openURL -URL was opened successfully");
})
.catch((err) => {
// execution reaches this point -> Error: Could not open URL 'casualjob://': No Activity found to handle Intent { act=android.intent.action.VIEW dat=casualjob:// flg=0x10000000
console.error("openURL - failed - err:", err, )
}); AndroidManifest.xml:

有关Deeplink集成，请参阅此插件反应-本机-深度连接
您的URL应该是这样的
const url = "https://buildwebsitepro.com.au" 之后，您需要首先初始化用于Android的Dee-link事件。
Linking.getInitialURL()
.then(ev => {
if (ev && ev !== '') {
handleUrl({url: ev});
}
})
.catch(err => console.log('An error occurred', err));
function handleUrl({url}: {url: string | null}) {
const deepLinkURL = url;
if (deepLinkURL) {
Linking.canOpenURL(deepLinkURL).then(supported => {
if (supported) {
DeepLinking.evaluateUrl(deepLinkURL);
}
});
}}
您需要像下面这样更改MenifestFile
<data android:host="casualjob" android:scheme="buildwebsitepro" />最后注册路由
DeepLinking.addRoute('/test/:id', (response) => {
// example://test/23
console.log(response.id); // 23

我发现问题是<data>定义之间的冲突。以下是显示所需修改的摘录。
AndroidManifest.xml:
<manifest ...>
...
<application ...>
...
<activity ...>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.BROWSABLE"/>
<data android:scheme="casualjob"/>
<!-- It seems that the following 2 data statements are conflicting with the one above. So, I removed them. -->
<!-- <data android:scheme="http" android:host="buildwebsitepro.com.au/casualjob"/>
<data android:scheme="https" android:host="buildwebsitepro.com.au/casualjob"/> -->
</intent-filter>
