链接在页面的第二个实例中不起作用，如果通过同一链接进入页面，该链接将向页面发送一个带有长 URL 查询的页面

Question

我正在处理非常长的 URL 或更具体的 URL 查询，我遇到了问题。

如果我使用已附加到这篇文章底部的 URL 执行 并单击它，它会为我提供与之前相同的页面，但 URL 查询很长，因为它是相同的页面它包含具有相同 URL 的相同 ，现在如果我再次单击该链接，它不会将我发送到该页面的新实例，它什么也不做，为什么会这样做？无论页面是什么实例，我都希望我的链接能够正常工作。

所以基本上我有一个带有链接的页面，该链接链接到同一页面但带有查询，如果通过该链接进入页面，此链接仅适用于页面的第一个实例，而不是第二个实例。

我只在 Firefox 和 Chromium 中测试过。

我在这里举了一个例子：http://173.45.231.202/hypnotic/link_problem.html，有问题的 URL 如下..

什么给了？

Answer 1

改为使用 POST 请求！ GET 请求的大小受到浏览器、Web 服务器和谁知道还有什么限制，从大约 256 个字符到 4000 个字符不等。因此，通常通过普通 GET 发送大量数据是不可靠的。通过 HTML 表单使用 POST 提交，您应该不会遇到任何问题。

Answer 2

IE 中支持的最大 URL 长度（GET）为 2048 个字符。一般来说，您希望避免超过 500 字节，因为某些浏览器和服务器实现不支持它。

如果您需要更大的集合，请使用来自表单操作的 POST 或处理来自服务器的返回值的 AJAX 请求。
