正则表达式查找字符串中的 URL

如果您有 url 模式，那么您应该能够在字符串中搜索它。只要确保该模式没有 ^和 $标记开始和结束的 URL 字符串。因此，如果 P 是 URL 的模式，则查找与 P 相匹配的。

这是我用的

(http|ftp|https):\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])

为我工作，也应该为你工作。

我使用在两个点或句点之间查找文本的逻辑

下面的 regex 可以很好地使用 python

(?<=\.)[^}]*(?=\.)

这是对 Rajeev 的回答(取决于你需要什么)的一个小小的改进:

([\w\-_]+(?:(?:\.|\s*\[dot\]\s*[A-Z\-_]+)+))([A-Z\-\.,@?^=%&:/~\+#]*[A-Z\-\@?^=%&/~\+#]){2,6}?

请参阅 给你以获得它的作用和不匹配的示例。

我摆脱了支票“ http”等，因为我想赶上网址的没有这一点。我稍微添加了正则表达式来捕捉一些模糊的 url (即用户使用[ dot ]而不是“”).最后，我将“ w”替换为“ A-Z”和“{2,3}”，以减少像 v2.0和“ moo. 0 dd”这样的假阳性。

欢迎有什么进展吗。

我使用下面的正则表达式在字符串中查找 url:

/(http|https)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/

我猜没有正则表达式是完美的这种使用。我发现了一个相当可靠的 给你

/(?:(?:https?|ftp|file):\/\/|www\.|ftp\.)(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[-A-Z0-9+&@#\/%=~_|$?!:,.])*(?:\([-A-Z0-9+&@#\/%=~_|$?!:,.]*\)|[A-Z0-9+&@#\/%=~_|$])/igm

与其他网站相比有一些不同/优点:

• 没有确实匹配电子邮件地址
• 它与 localhost: 12345匹配
• 如果没有 http或者 www它就检测不到类似 moo.com的东西

有关示例，请参见 给你

这是最好的一个。

NSString *urlRegex="(http|ftp|https|www|gopher|telnet|file)(://|.)([\\w_-]+(?:(?:\\.[\\w_-]+)‌​+))([\\w.,@?^=%&:/~+#-]*[\\w@?^=%&/~+#-])?";

上述所有答案都与 URL 中的 Unicode 字符不匹配，例如: http://google.com?query=đức+filan+đã+search

为了解决这个问题，这个方法应该奏效:

(ftp:\/\/|www\.|https?:\/\/){1}[a-zA-Z0-9u00a1-\uffff0-]{2,}\.[a-zA-Z0-9u00a1-\uffff0-]{2,}(\S*)

匹配文本中的 URL 不应该如此复杂

(?:(?:(?:ftp|http)[s]*:\/\/|www\.)[^\.]+\.[^ \n]+)

Https://regex101.com/r/wewpp1/2

这里提供的解决方案都没有解决我所遇到的问题/用例。

我在这里提供的是迄今为止我发现/制作的最好的。我会更新它时，我发现新的边缘案件，它不处理。

\b
#Word cannot begin with special characters
(?<![@.,%&#-])
#Protocols are optional, but take them with us if they are present
(?<protocol>\w{2,10}:\/\/)?
#Domains have to be of a length of 1 chars or greater
((?:\w|\&\#\d{1,5};)[.-]?)+
#The domain ending has to be between 2 to 15 characters
(\.([a-z]{2,15})
#If no domain ending we want a port, only if a protocol is specified
|(?(protocol)(?:\:\d{1,6})|(?!)))
\b
#Word cannot end with @ (made to catch emails)
(?![@])
#We accept any number of slugs, given we have a char after the slash
(\/)?
#If we have endings like ?=fds include the ending
(?:([\w\d\?\-=#:%@&.;])+(?:\/(?:([\w\d\?\-=#:%@&;.])+))*)?
#The last char cannot be one of these symbols .,?!,- exclude these
(?<![.,?!-])

简短而简单。我还没有在 javascript 代码中测试过，但看起来它可以工作:

((http|ftp|https):\/\/)?(([\w.-]*)\.([\w]*))

Regex101.com 上的代码

如果你必须严格选择链接，我会选择:

(?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.\-]+[.][a-z]{2,4}/)(?:[^\s()<>]+|\(([^\s()<>]+|(\([^\s()<>]+\)))*\))+(?:\(([^\s()<>]+|(\([^\s()<>]+\)))*\)|[^\s`!()\[\]{};:'".,<>?«»“”‘’]))

一种改进的自由精确匹配 URL 正则表达式模式

我认为这个 regex 模式可以精确地处理您想要的内容

/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/

这是一个提取 Urls 的片段示例:

// The Regular Expression filter
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";


// The Text you want to filter for urls
$text = "The text you want  https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string to filter goes here.";


// Check if there is a url in the text
preg_match_all($reg_exUrl, $text, $url,$matches);
var_dump($matches);

我用了这个

^(https?:\\/\\/([a-zA-z0-9]+)(\\.[a-zA-z0-9]+)(\\.[a-zA-z0-9\\/\\=\\-\\_\\?]+)?)$

一种可能过于简单但有效的方法可能是:

[localhost|http|https|ftp|file]+://[\w\S(\.|:|/)]+

我在 Python 上进行了测试，只要字符串解析包含前后空格，而 url 中没有空格(我以前从未见过) ，就应该没问题。

下面是一个在线演示

然而，使用它有一些好处:

• 它识别 file:和 localhost以及 ip 地址
• 没有它们 永远不会也会匹配
• 它不介意不寻常的字符，如 #或 -(见这篇文章的网址)

text = """The link of this question: https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string
Also there are some urls: www.google.com, facebook.com, http://test.com/method?param=wasd, http://test.com/method?param=wasd&params2=kjhdkjshd
The code below catches all urls in text and returns urls in list."""


urls = re.findall('(?:(?:https?|ftp):\/\/)?[\w/\-?=%.]+\.[\w/\-&?=%.]+', text)
print(urls)

产出:

[
'https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string',
'www.google.com',
'facebook.com',
'http://test.com/method?param=wasd',
'http://test.com/method?param=wasd&params2=kjhdkjshd'
]

这是最简单的一个，对我来说很好用。

%(http|ftp|https|www)(://|\.)[A-Za-z0-9-_\.]*(\.)[a-z]*%

使用@JustinLevene 提供的 regex 在反斜杠上没有正确的转义序列。更新到现在是正确的，并添加在条件匹配的 FTP 协议以及: 将匹配到所有的网址有或没有协议，没有“ www”

密码: ^((http|ftp|https):\/\/)?([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?

例子: https://regex101.com/r/uQ9aL4/65

我找到了涵盖大多数示例链接的 这个，包括子目录部分。

正则表达式是:

(?:(?:https?|ftp):\/\/|\b(?:[a-z\d]+\.))(?:(?:[^\s()<>]+|\((?:[^\s()<>]+|(?:\([^\s()<>]+\)))?\))+(?:\((?:[^\s()<>]+|(?:\(?:[^\s()<>]+\)))?\)|[^\s`!()\[\]{};:'".,<>?«»“”‘’]))?

我使用这个正则表达式:

/((\w+:\/\/\S+)|(\w+[\.:]\w+\S+))[^\s,\.]/ig

它适用于许多 URL，比如: Http://google.com 公司网址: www.regexr.com 本地主机: 8080/path..。

进步了

像这样检测 Urls:

• Https://www.example.pl
• Http://www.example.com
• Www.example.pl
• Example.com
• Http://blog.example.com
• Http://www.example.com/product
• Http://www.example.com/products?id=1&page=2
• Http://www.example.com#up
• Http://255.255.255.255
• 255.255.255.255
• Http://www.site.com: 8008

正方糖:

/^(?:http(s)?:\/\/)?[\w.-]+(?:\.[\w\.-]+)+[\w\-\._~:/?#[\]@!\$&'\(\)\*\+,;=.]+$/gm

很简单。

使用这个模式: \b((ftp|https?)://)?([\w-\.]+\.(com|net|org|gov|mil|int|edu|info|me)|(\d+\.\d+\.\d+\.\d+))(:\d+)?(\/[\w-\/]*(\?\w*(=\w+)*[&\w-=]*)*(#[\w-]+)*)?

它与包含以下内容的任何链接相匹配:

允许的协议: http，https 和 ftp

允许域名: * .com，* .net，* .org，* . gov，* . mil，* . int，* . edu，* . info and * . me OR IP

允许端口: 正确

允许参数: true

允许的 Hash: 正确

(?:vnc|s3|ssh|scp|sftp|ftp|http|https)\:\/\/[\w\.]+(?:\:?\d{0,5})|(?:mailto|)\:[\w\.]+\@[\w\.]+

如果您希望了解每个部分的说明，请尝试使用 regexr [ . ]你会得到一个伟大的解释，每个字符。

这由“ |”或“ OR”分割，因为并非所有可用的 URI 都有“//”，所以您可以在这里创建您感兴趣的方案或条件的列表。

这里稍微优化了一下 regexp:

(?:(?:(https?|ftp|file):\/\/|www\.|ftp\.)|([\w\-_]+(?:\.|\s*\[dot\]\s*[A-Z\-_]+)+))([A-Z\-\.,@?^=%&:\/~\+#]*[A-Z\-\@?^=%&\/~\+#]){2,6}?

下面是数据测试: https://regex101.com/r/sFzzpY/6

我已经利用 c # Uri 类和它的工作，以及与 IP 地址，本地主机

 public static bool CheckURLIsValid(string url)
{
Uri returnURL;


return (Uri.TryCreate(url, UriKind.Absolute, out returnURL)
&& (returnURL.Scheme == Uri.UriSchemeHttp || returnURL.Scheme == Uri.UriSchemeHttps));




}

我喜欢 Stefan Henze 的解决方案，但是它会回升到34.56。它太笼统了，我没有解析 html。一个 url 有4个锚点;

Www,

上面解决了几乎所有的问题，除了像“ eurls: www.google.com，facebook.com， http://test.com/"”这样的字符串，它以单个字符串的形式返回。我为什么要加地鼠等等。 证据 R 代码

你可以根据需要调整 看看它在 regex101上的表现

这个正则表达式非常适合我，也应该适合你

(http|ftp|https)://([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:/~+#-]*[\w@?^=%&/~+#-])?

这个怎么样？

(http:\/\/|ftp:\/\/|https:\/\/|www\.)([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?

它与问题中的两个都吻合。

这个稍微简单一点的版本对我很有用(并且支持 # 和其他字符，代价是增加‘假阳性’) :

import re
text = """The link of this question: https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string
Also there are some urls: www.google.com, facebook.com, http://test.com/method?param=wasd, http://test.com/method?param=wasd&params2=kjhdkjshd#changed
The code below catches all urls in text and returns urls in list."""


regex = r"(?i)(https?://|www.|\w+\.)[^\s]+"
urls = [match.group() for match in re.finditer(regex, text)]
print(urls)

和输出

[
'https://stackoverflow.com/questions/6038061/regular-expression-to-find-urls-within-a-string',
'www.google.com,',
'facebook.com,',
'http://test.com/method?param=wasd,',
'http://test.com/method?param=wasd&params2=kjhdkjshd#changed'
]

这个表达式还可以找到类似于:/path/text.html 的路径

(https?\:\/[^\"\'\n\<\>\;\)\s]*)|(www?\.[^\"\'\n\<\>\;\s]*)|([^\s\&\=\;\,\<\<\>\"\'\(\)]+\/[\w\/])([^\"\'\n\;\s]*)|((?<!\<)[\/]+[\w]+[^\'\"\s\<\>]*)

这个正则表达式甚至捕获像 goo.gl或 domains.google这样的域。
