StatusBarItem的寄存器命令

Question

我正在创建一个Visual代码扩展，并阅读了它，以便为StatusBarItem onclick事件提供为状态栏项注册命令所需的功能。我该怎么做？当我使用StatusBarItem创建window.createStatusBarItem时，我得到一个对象，它似乎没有任何字符串作为标识符，但是命令注册过程需要一个字符串作为第一个参数，我不知道如何将它与StatusBarItem相关联。

我使用了yeoman来引导一个JavaScript扩展。

extension.js

const vscode = require('vscode');
const { exec } = require('child_process')

function activate(context) {
    console.log('Thanks for installing me! Remember to add a script to run if you want this extension to do anything \
    instersting at all :P');

    // TODO: make status bar item clickable
    const statusBarItem = vscode.window.createStatusBarItem(vscode.StatusBarAlignment.Right, 1000);

    function runCommandAndUpdateStatusBarItem () {
        // TODO: fetch command from settings
        const command = 'git describe --dirty="-$USER"';
        exec(`cd ${vscode.workspace.rootPath} && ${command}`, [], (error, stdout, stderr) => {
            if (stdout) {
                statusBarItem.text = `$(git-commit) ${stdout}`;
                statusBarItem.show();
            }
            else {
                vscode.window.showErrorMessage(stderr);
                statusBarItem.hide();
            }
        });
    }

    statusBarItem.hide();

    let disposable = vscode.commands.registerCommand('extension.sayHello', runCommandAndUpdateStatusBarItem);

    context.subscriptions.push(statusBarItem);
    context.subscriptions.push(disposable);
}
exports.activate = activate;

function deactivate() {
    console.log('Oh...so, you hate me? Ok I go away now :(');
}
exports.deactivate = deactivate;

当我使用StatusBarItem创建window.createStatusBarItem时，我得到一个似乎没有任何字符串作为标识符的对象

默认情况下，它不是可选的，是的，但是您可以在上面设置command：

statusBarItem.command = 'extension.sayHello';

检查API文档中的StatusBarItem：https://code.visualstudio.com/docs/extensionAPI/vscode-api#StatusBarItem
