下面是Mac OSx的2.0.0版本:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "echo",
      "type": "shell",
      "command": "echo Hello"
    },
    {
      "label":"chrome",
      "type":"process",
      "command":"/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
      "args": [
        "${file}"
      ]
    }
  ]
}

VSCode任务-通过应用程序包标识符打开(仅限macOS)。

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Open In: Firefox DE",
      "type": "process",
      "command": "open",
      "args": ["-b", "org.mozilla.firefoxdeveloperedition", "${file}"],
      "group": "build",
      "problemMatcher": [],
      "presentation": {
        "panel": "shared",
        "focus": false,
        "clear": true,
        "reveal": "never",
      }
    }
  ]
}

Windows -打开默认浏览器-在VS Code v 1.1.0上测试

回答既打开一个特定的文件(名称是硬编码)或打开任何其他文件。

步骤:

Use ctrl + shift + p (or F1) to open the Command Palette. Type in Tasks: Configure Task or on older versions Configure Task Runner. Selecting it will open the tasks.json file. Delete the script displayed and replace it by the following: { "version": "0.1.0", "command": "explorer", "windows": { "command": "explorer.exe" }, "args": ["test.html"] } Remember to change the "args" section of the tasks.json file to the name of your file. This will always open that specific file when you hit F5. You may also set the this to open whichever file you have open at the time by using ["${file}"] as the value for "args". Note that the $ goes outside the {...}, so ["{$file}"] is incorrect. Save the file. Switch back to your html file (in this example it's "text.html"), and press ctrl + shift + b to view your page in your Web Browser.

您现在可以在浏览器中安装一个扩展视图。我在chrome的windows上测试了它，它是工作的。

Vscode版本:1.10.2

如果你只是在Mac上，这个任务。json文件:

{
    "version": "0.1.0",
    "command": "open",
    "args": ["${file}"],
}

.．.在Safari中打开当前文件(假设扩展名为“.html”)所需要的全部内容。

创建任务。Json，并使用⌘+shift+b调用它。

如果你想在Chrome中打开它，那么:

{
    "version": "0.1.0",
    "command": "open",
    "args": ["-a", "Chrome.app", "${file}"],
}

这将做你想要的，如在打开一个新的标签，如果应用程序已经打开。
