将用户特定的URL列表与当前的URL进行比较？ [英] Comparing user-specific URL list with current URL?
问题描述
我有一个白名单，用户可以输入特定的URL / URL模式（只针对 http 和 https 。
我想转换并比较这些网址/网址格式，以便通配符选择符（ *
用户输入：
示例。* / test
我想将它转换为：
* // *。example 。* / test
，以便它匹配：
http：// www。 example.com/test，https://example.co.uk/test
另一个例子：
用户输入：
http：//www.*.com/*
我想将其转换为：
http：//www.*.com/*
，以便它匹配：
http://www.blah.com/test，http ：//www.other.com/null.html
和
用户输入：
www.example.com / *
我想将其转换为：
，以便它匹配：
http://www.example.com/testtwo，https://www.example.com/arfg
我想要的理由插入一个领先的协议（如果它没有被用户包括在内）是因为我使用这个来比较当前标签的URL。
我得到这个数组URL字符串，并希望将它们与当前网址进行比较，但在匹配所有用例时遇到问题：
isNotWhitelisted： function（）{
var whitelist = MyObject.userLists.whitelist;
var currentUrl = document.location.href;
for（var i = 0; i< whitelist.length; i ++）{
var regexListItem = new RegExp（whitelist [i] .toString（）。replace（。，\\ 。）。replace（*，。+））;
if（currentUrl.match（regexListItem））{
return false;
}
}
返回true;
}，

首先，正则表达式转换匹配最终用例（例如
example.com / *，但不包含例子。* / about -
这是Chrome扩展的一部分，是否没有更好/更简单的方法来使用内置方法？
感谢您提前提供任何帮助。 解决方案
贪婪的匹配，我想你需要请求用户以这种格式输入模式： *：// * / *
<你可以用这种方式检查它：
var special_char_rgx = /((.\\.|\[|\] | \ {| \} | \（| \）| \ + | \ | | \\ | \ / | \ $ | \ ^ | \ |）/ g; / /我认为所有...
var asterisk_rgx = / \ * / g;
var pattern_rgx = / ^（[^：\ /] +）：\ / \ /（[ ^ \ /] +）\ /(.*)$/ g;
function addPatern（pattern，whitelist）{
var str_pattern = p如果（isMatch）{
pattern = pattern.replace（special_char_rgx，'）'， '\\ $ 1'）。replace（asterisk_rgx，'。+'）;
whitelist.push（new RegExp（'^'+ pattern +'$'））;
}
pattern_rgx.lastIndex = 0; //否则RegExp.test保存该值并销毁测试！
返回isMatch;
$ b如果你想用不同的方式处理协议/域/路径，你可以做这样：
if（isMatch）{
var protocol = RegExp。$ 1;
var domain = RegExp。$ 2;
var path_query = RegExp。$ 3;
//您的逻辑...
}
I have a whitelist where users can enter specific URLs/URL patterns (only targetting http and https.
I would like to transfrom and compare these URL/URL patterns so that the wildcard selector (*) can be used like so
user enters: example.*/test
I want to transform this to: *//*.example.*/test
so that it matches: http://www.example.com/test, https://example.co.uk/test
Another example:
user enters: http://www.*.com/*
I want to transform this to: http://www.*.com/*
so that it matches: http://www.blah.com/test, http://www.other.com/null.html
and
user enters: www.example.com/*
I want to transform this to: *//www.example.com/*
so that it matches: http://www.example.com/testtwo, https://www.example.com/arfg
The reason I want to insert a leading protocol (if it wasn't included by the user) is because I am using this to compare against the current tab URL.
I get this array of URL strings and would like to compare them with the current url, but am having trouble matching all use cases:
"isNotWhitelisted" : function(){
var whitelist = MyObject.userLists.whitelist;
var currentUrl = document.location.href;
for(var i=0; i<whitelist.length; i++){
var regexListItem = new RegExp(whitelist[i].toString().replace(".", "\\.").replace("*", ".+"));
if(currentUrl.match(regexListItem)) {
return false;
}
}
return true;
},
Firstly, the regex conversion matches end cases (e.g. example.com/* but not kinds like example.*/about
This is part of a Chrome extension, is there not a better/easier way to do this maybe using inbuilt methods?
Thanks for any help in advance.
解决方案 If you want a greedy matching, I think you need request the user enter the pattern in this format: *://*/*
You can check this in this way:
var special_char_rgx = /(\.|\[|\]|\{|\}|\(|\)|\+|\?|\\|\/|\$|\^|\|)/g; // I think that all...
var asterisk_rgx = /\*/g;
var pattern_rgx = /^([^:\/]+):\/\/([^\/]+)\/(.*)$/g;
function addPatern(pattern, whitelist) {
var str_pattern = pattern.replace(asterisk_rgx,'\\*');
var isMatch = pattern_rgx.test(str_pattern);
if (isMatch) {
pattern = pattern.replace(special_char_rgx,'\\$1').replace(asterisk_rgx, '.+');
whitelist.push(new RegExp('^'+pattern + '$'));
}
pattern_rgx.lastIndex = 0; // Otherwise RegExp.test save this value and destroy the tests!
return isMatch;
}
If you want handle the protocol/ domain/ path in different ways you can do it that way:
if (isMatch) {
var protocol = RegExp.$1;
var domain= RegExp.$2;
var path_query = RegExp.$3;
// Your logic...
}
