是否有任何方法从Visual代码扩展的way视图导航到外部Windows应用程序？
是否有任何方法从Visual代码扩展的way视图导航到外部Windows应用程序？
提问于 2019-08-19 13:24:31
我正在开发一个Visual代码扩展，它将在某些事件上打开一个some视图。Webview有以下链接地址的一些链接：
reqtify:////NKR8WIN764PLP/Users//Public/Documents/Reqtify/2020x/Examples/Coupling/Code/Code%20C/Code%20Sample.rqtf?id=SPEC_2
使用此URI，应该导航到外部Windows应用程序。当我在Chrome/Firefox浏览器中使用这个URI时，我能够导航到目标外部Windows应用程序。但是在我的扩展的when视图中，当我点击这个链接时，我得到了以下错误：
Uncaught Error: [UriError]: If a URI does not contain an authority component, then the path cannot begin with two slash characters ("//")
我尝试将所有"//“替换为"/”，以生成URI : reqtify:/NKR8WIN764PLP/Users/Public/Documents/Reqtify/2020x/Examples/Coupling/Code/Code%20C/Code%20Sample.rqtf?id=SPEC_2
但是，我仍然无法导航到外部Windows应用程序。
下面是我的呈现the视图的代码：
protected async doUpdate(): Promise<void> {
let content: string;
this.throttleTimer = undefined;
content = await this.contentProvider.provideRequirementsContent(document.uri,
this.state, this.editor.webview);
this.editor.webview.options = getWebviewOptions(this.contentProvider);
this.editor.webview.html = content;
}
protected static getWebviewOptions(contentProvider: BaseContentProvider
): vscode.WebviewOptions {
return {
enableScripts: true,
localResourceRoots: contentProvider.localResourceRoots
};
}
public async provideRequirementsContent(sourceUri: vscode.Uri, state: any, webview: any): Promise<string> {

经过一些研究，我设法解决了这个问题，但我不确定它是否正确的方式。
我在上面的HTML字符串中添加了一个脚本，其中包含了一个在body的load事件上调用的方法。
因此，我的最后一个HTML字符串将类似于：
let html = "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
</head>
<body onload="myFunction()>
<div class="sect2">

<col width="80"></col>

<script>
function myFunction() {
const vscode = acquireVsCodeApi();
let reqs = document.getElementsByTagName('a');
for (let item of reqs) {
item.addEventListener('click', function() {
vscode.postMessage({
command: 'open',
text: item.getAttribute('href')
})
return false;
}, false);
}
}
</script>
</body>
</html>
"如果您观察到脚本，我将使用onDidReceiveMessage发送一条包含命令"open“和url作为数据的消息，该消息将由webview的onDidReceiveMessage方法接收，如下所示：
this.editor.webview.onDidReceiveMessage(message => {
switch (message.command) {
case 'open':
var url = message.text;
var start = (process.platform === 'darwin'? 'open': process.platform === 'win32'? 'start': 'xdg-open');
require('child_process').exec(start + ' ' + url);
}
}, null, super.disposables);当从postMessage接收到"open“命令时，我在Nodejs的帮助下使用url导航到外部应用程序。
谢谢。
