如何编码URL作为GET参数传递 [英] How to encode a URL for passing it as a GET parameter

问题描述

我加载一个将当前页面的URL作为参数的JavaScript文件。这是我使用的代码：

I load a JavaScript file which takes current page's URL as a parameter. Here is the code I use:

document.write(unescape('%3Cscript src=\"' + _vis_opt_protocol + 'domain.com/js.php&a='+account_id+'&url='+encodeURIComponent(document.URL)+'&random='+Math.random()+'\" type=\"text/javascript\"%3E%3C/script%3E'));

我认为encodeURIComponent会做正确编码URL的工作。但是，当加载JS文件时，浏览器也会解码编码的URL。例如，如果document.URL是 http://example.com/?test=1#nono 然后浏览器将测试解释为JS的另一个参数，并且不会在（和包括）#nono之后发送任何内容，因为它认为它是一个锚点。

I thought encodeURIComponent will do the job of properly encoding the URL. However, while loading JS file, browsers interpret the encoded URL too. For example if the document.URL is http://example.com/?test=1#nono then the browser interprets test as another parameter to JS and doesn't send anything after (and including) #nono because it thinks it is an anchor.

对URL进行编码的最佳方式是什么，以便将其传递到服务器？我也是用base64或其他一些形式的编码。

What is the best way to encode the URL so that it is passed as it is to the server? I was also toying with base64 or some other form of encoding.

推荐答案

问题是 unescape 函数你正在调用undoes做工作的 encodeURIComponent 。您可以尝试以下方式：

The problem is that the unescape function you are calling undoes do job of encodeURIComponent. You may try this:

document.write('<script type="text/javascript" src="' + _vis_opt_protocol + 'domain.com/js.php&a=' + account_id + '&url=' + encodeURIComponent(document.URL) + '&random=' + Math.random() + '"><\/sc' + 'ript>');
