## ❗️ Attention ❗️- Workaround to login to LeetCode endpoint
## Login

> Note: If you are using `leetcode.cn`, you can just ignore this section.
> Note: If you are using `leetcode.cn`, switch the endpoint to `leetcode-cn` first.

Recently we observed that [the extension cannot login to leetcode.com endpoint anymore](https://github.com/LeetCode-OpenSource/vscode-leetcode/issues/478). The root cause of this issue is that leetcode.com changed its login mechanism and so far there is no ideal way to fix that issue.

Thanks for [@yihong0618](https://github.com/yihong0618) provided a workaround which can somehow mitigate this. Now you can simply click the `Sign In` button and then select `Third Party` login or `Cookie` login.

> Note: If you want to use third-party login(**Recommended**), please make sure your account has been connected to the third-party. If you want to use `Cookie` login, click [here](https://github.com/LeetCode-OpenSource/vscode-leetcode/issues/478#issuecomment-564757098) to see the steps.
Run **LeetCode: Sign in** and choose **LeetCode Cookie** (paste the `Cookie` request header from a signed-in browser session) or **Web Authorization**. Cookies are stored in VS Code `SecretStorage`, not in plain text settings.

## Requirements

- [VS Code 1.30.1+](https://code.visualstudio.com/)
- [Node.js 10+](https://nodejs.org)
> NOTE: Please make sure that `Node` is in your `PATH` environment variable. You can also use the setting `leetcode.nodePath` to specify the location of your `Node.js` executable.
- [VS Code 1.90+](https://code.visualstudio.com/)
- No Node.js installation is required; the extension calls LeetCode's HTTPS APIs directly.

## Quick Start

![demo](https://raw.githubusercontent.com/LeetCode-OpenSource/vscode-leetcode/master/docs/gifs/demo.gif)

## Features

> The bundled LeetCode CLI and Node.js dependency were removed; authentication, problems, statements, solutions, tests, and submissions use LeetCode's GraphQL/REST endpoints directly.

## ❗️ 注意 ❗️- 无法登录 LeetCode 节点的临时解决办法
## 登录

> 注意：如果使用的是 `leetcode.cn` 账户，可以跳过此段落。
> 注意：使用 `leetcode.cn` 时请先把站点切换为 `leetcode-cn`。

近期我们发现插件出现了[无法登录 leetcode.com 节点的问题](https://github.com/LeetCode-OpenSource/vscode-leetcode/issues/478)。原因是因为近期 leetcode.com 改变了登录机制，目前我们暂时没有找到解决该问题的完美解决方案。

感谢 [@yihong0618](https://github.com/yihong0618) 提供了一个临时解决办法。现在你可以直接点击登录按钮并选择第三方登录或者 `Cookie` 登录。

> 注意：如果你希望使用第三方登录（**推荐**），请确保你的账户已经与第三方账户连接。如果你希望通过 `Cookie` 登录，请点击[该连接](https://github.com/LeetCode-OpenSource/vscode-leetcode/issues/478#issuecomment-564757098)查看登录步骤。
执行 **LeetCode: Sign in**，选择 **LeetCode Cookie**（粘贴已登录浏览器里的 `Cookie` 请求头）或 **Web Authorization**。Cookie 保存在 VS Code `SecretStorage` 中，不会写入明文设置。

## 运行条件

- [VS Code 1.23.0+](https://code.visualstudio.com/)
- [Node.js 10+](https://nodejs.org)
> 注意：请确保`Node`在`PATH`环境变量中。您也可以通过设定 `leetcode.nodePath` 选项来指定 `Node.js` 可执行文件的路径。
- [VS Code 1.90+](https://code.visualstudio.com/)
- 不需要安装 Node.js；扩展直接调用 LeetCode 的 HTTPS API。

## 快速开始

![demo](https://raw.githubusercontent.com/LeetCode-OpenSource/vscode-leetcode/master/docs/gifs/demo.gif)

## 功能

> 已移除内置的 LeetCode CLI 与 Node.js 依赖；登录、题库、题干、题解、测试和提交均直接使用 LeetCode 的 GraphQL/REST 接口。
