@UvDream 官方有个类似的示例，你可以参考: https://microsoft.github.io/monaco-editor/playground.html?source=v0.43.0#example-extending-language-services-hover-provider-example

monaco.languages.register({ id: "mySpecialLanguage" });

monaco.languages.registerHoverProvider("mySpecialLanguage", {
    provideHover: function (model, position) {
        return xhr("./playground.html").then(function (res) {
            return {
                range: new monaco.Range(
                    1,
                    1,
                    model.getLineCount(),
                    model.getLineMaxColumn(model.getLineCount())
                ),
                contents: [
                    { value: "**SOURCE**" },
                    {
                        value:
                            "```html\n" +
                            res.responseText.substring(0, 200) +
                            "\n```",

});

monaco.editor.create(document.getElementById("container"), {

                    (req.status >= 200 && req.status < 300) ||
                    req.status === 1223
                ) {
                    c(req);
                } else {

                req.onreadystatechange = function () {};
