在 NodeJS 中获取页面的 HTML 源代码

Question

由于 cors 限制，我目前正在努力获取 NodeJS 中网页的 HTML 源代码。 我正在使用 JQuery 向需要 HTML 响应的页面发出 GET 请求。 然而，这会引发错误XMLHttpRequest cannot load https://www.reddit.com/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8000' is therefore not allowed access XMLHttpRequest cannot load https://www.reddit.com/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8000' is therefore not allowed access XMLHttpRequest cannot load https://www.reddit.com/. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8000' is therefore not allowed access 。 有没有办法使用 NodeJS 绕过 CORS？ （比如通过代理）

        $.ajax({
        url: 'https://www.reddit.com/',
        headers: {
            'Content-Type': 'text/html',
            "Access-Control-Allow-Origin": '*'
        },
        type: "GET",
        data: {
        },
        success: function (result) {
            console.log(result);    
        },
        error: function () {
            console.log("error");
        }
    });

我也在使用带有以下标头的 webpack 开发服务器

    headers: {
        "Access-Control-Allow-Origin": '*',
        "Access-Control-Allow-Credentials": "true",
        "Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, OPTIONS"
    }

不要在 nodejs 中使用 jquery，你可以使用这个库来实现你需要的东西：

• 同构取指
• 要求
