VS Code 扩展可以从其他程序获取 URI 请求吗? [英] Can VS Code extensions get URI requests from other programs?

问题描述

我在官方文档中找到了 onUri 可以用作激活事件的信息.因此，我的扩展程序可以通过调用 URI(例如 vscode://myextension/arg1=foo&arg2=bar)从用 C# 编写的 WPF 程序激活.但是它没有说明我如何获取随 URI 请求传递的参数.或者甚至只是获取它的原始字符串.

I found information on the official docs that onUri can be used as an activation event. So, my extension can be activated from, say, a WPF program written in C# by calling the URI such as vscode://myextension/arg1=foo&arg2=bar. But nowhere does it say how I can get the arguments that were passed with the URI request. Or even just get a raw string of it.

我的问题是，能不能实现，如果不能，有没有其他方法可以让 VS Code 扩展与另一个程序交互?

My question is, can it be done and if not, is there any other way to make a VS Code extension interact with another program?

推荐答案

是的，你可以使用 vscode.window.registerUriHandler() 为此:

Yes, you can use vscode.window.registerUriHandler() for this:

注册一个 uri 处理程序，能够处理系统范围的uris.如果有多个窗口打开，最上面的窗口将处理 uri.uri 处理程序的范围限定于它所提供的扩展；它只能处理指向扩展本身的 uri.uri 必须遵守以下规则:

Registers a uri handler capable of handling system-wide uris. In case there are multiple windows open, the topmost window will handle the uri. A uri handler is scoped to the extension it is contributed from; it will only be able to handle uris which are directed to the extension itself. A uri must respect the following rules:

• uri-scheme 必须是产品名称；

• The uri-scheme must be the product name;

uri-authority 必须是扩展名(例如 my.extension)；

The uri-authority must be the extension id (eg. my.extension);

一个扩展在其整个激活生命周期内只能注册一个 uri 处理程序.

An extension can only register a single uri handler in its entire activation lifetime.

• 注意:有一个激活事件 onUri 在即将处理指向当前扩展的 uri 时触发.

• Note: There is an activation event onUri that fires when a uri directed for the current extension is about to be handled.

用法很简单:

vscode.window.registerUriHandler({
    handleUri(uri:vscode.Uri) {
        // do something with the URI
    }
});
