JavaScript Kullanarak URL Doğrulamaya Çalışmak

Bir URL'yi doğrulamak ve mesaj görüntülemek istiyorum. Kodum aşağıdadır:

$("#pageUrl").keydown(function(){
        $(".status").show();
        var url = $("#pageUrl").val();

        if(isValidURL(url)){

        $.ajax({
            type: "POST",
            url: "demo.php",
            data: "pageUrl="+ url,
            success: function(msg){
                if(msg == 1 ){
                    $(".status").html('<img src="images/success.gif"/><span><strong>SiteID:</strong>12345678901234456</span>');
                }else{
                    $(".status").html('<img src="images/failure.gif"/>');
                }
            }
            });

            }else{

                    $(".status").html('<img src="images/failure.gif"/>');
            }

    });


function isValidURL(url){
    var RegExp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

    if(RegExp.test(url)){
        return true;
    }else{
        return false;
    }
} 

Benim sorunum şu ki, normal ifadeyle eşleşene kadar uygun bir URL girerken bile bir hata mesajı gösterecek ve URL gibi bir şey olsa bile doğru dönecek "http://wwww".

Önerilerinizi takdir ediyorum.

Birisi Jquery Doğrulama eklentisinden bahsetti, sadece url'yi doğrulamak istiyorsanız aşırı görünüyor, işte eklentiden normal ifade satırı:

Normal ifadeyi kullanarak URL'leri ayrıştırmak pratik değildir. RFC1738 kurallarının tam olarak uygulanması, son derece uzun bir düzenli ifadeyle sonuçlanır (mümkün olduğunu varsayarsak). Kesinlikle mevcut ifadeniz birçok geçerli URL'de başarısız oluyor ve geçersiz olanları iletiyor.

Yerine:

a. gerçek kuralları izleyen uygun bir URL ayrıştırıcısı kullanın. (JavaScript için bir tane bilmiyorum; muhtemelen abartılı olur. Bunu sunucu tarafında da yapabilirsiniz). Veya,

b. sadece baştaki veya sondaki boşlukları kesin, ardından ön tarafta tercih ettiğiniz şemalardan birinin (genellikle 'http: //' veya 'https: //') olup olmadığını kontrol edin ve öyle bırakın. Veya,

c. URL'yi kullanmaya çalışın ve sonunda ne olduğunu görün, örneğin sunucu tarafından HTTP HEAD isteği göndererek. Bir 404 veya bağlantı hatası alırsanız, muhtemelen yanlıştır.

url " http: // wwww " gibi bir şey olsa bile doğru döndürür .

Bu gerçekten de tamamen geçerli bir URL.

'Wwww' gibi bir ana bilgisayar adının gerçekten var olup olmadığını kontrol etmek istiyorsanız, DNS'de aramaktan başka seçeneğiniz yoktur. Yine, bu sunucu tarafı kodu olacaktır.

function validateURL(textval) {
    var urlregex = /^(https?|ftp):\/\/([a-zA-Z0-9.-]+(:[a-zA-Z0-9.&%$-]+)*@)*((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9][0-9]?)(\.(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9]?[0-9])){3}|([a-zA-Z0-9-]+\.)*[a-zA-Z0-9-]+\.(com|edu|gov|int|mil|net|org|biz|arpa|info|name|pro|aero|coop|museum|[a-zA-Z]{2}))(:[0-9]+)*(\/($|[a-zA-Z0-9.,?'\\+&%$#=~_-]+))*$/;
    return urlregex.test(textval);
}

Bu, aşağıdaki gibi URL'ler için doğru olarak dönebilir:

http://stackoverflow.com/questions/1303872/url-validation-using-javascript

veya:

http://regexlib.com/DisplayPatterns.aspx?cattabindex=1&categoryId=2

Ayrıca http ve https url'lerini kontrol etmek için rfc1738 ve rfc3986'da bir URL doğrulama işlevi yazdım. Bu modüler tutmaya çalışıyorum, böylece daha iyi korunabilir ve kendi gereksinimlerine uyarlanabilir.

Tek satırdaki RegExp, bu gönderinin sonunda gösterilir.

RegExp, bazı uluslararası alan veya IPv4 numaralarına sahip HTTP ve HTTPS URL'lerini kabul eder. IPv6 henüz desteklenmiyor.

window.isValidURL = (function() {// wrapped in self calling function to prevent global pollution

     //URL pattern based on rfc1738 and rfc3986
    var rg_pctEncoded = "%[0-9a-fA-F]{2}";
    var rg_protocol = "(http|https):\\/\\/";

    var rg_userinfo = "([a-zA-Z0-9$\\-_.+!*'(),;:&=]|" + rg_pctEncoded + ")+" + "@";

    var rg_decOctet = "(25[0-5]|2[0-4][0-9]|[0-1][0-9][0-9]|[1-9][0-9]|[0-9])"; // 0-255
    var rg_ipv4address = "(" + rg_decOctet + "(\\." + rg_decOctet + "){3}" + ")";
    var rg_hostname = "([a-zA-Z0-9\\-\\u00C0-\\u017F]+\\.)+([a-zA-Z]{2,})";
    var rg_port = "[0-9]+";

    var rg_hostport = "(" + rg_ipv4address + "|localhost|" + rg_hostname + ")(:" + rg_port + ")?";

    // chars sets
    // safe           = "$" | "-" | "_" | "." | "+"
    // extra          = "!" | "*" | "'" | "(" | ")" | ","
    // hsegment       = *[ alpha | digit | safe | extra | ";" | ":" | "@" | "&" | "=" | escape ]
    var rg_pchar = "a-zA-Z0-9$\\-_.+!*'(),;:@&=";
    var rg_segment = "([" + rg_pchar + "]|" + rg_pctEncoded + ")*";

    var rg_path = rg_segment + "(\\/" + rg_segment + ")*";
    var rg_query = "\\?" + "([" + rg_pchar + "/?]|" + rg_pctEncoded + ")*";
    var rg_fragment = "\\#" + "([" + rg_pchar + "/?]|" + rg_pctEncoded + ")*";

    var rgHttpUrl = new RegExp( 
        "^"
        + rg_protocol
        + "(" + rg_userinfo + ")?"
        + rg_hostport
        + "(\\/"
        + "(" + rg_path + ")?"
        + "(" + rg_query + ")?"
        + "(" + rg_fragment + ")?"
        + ")?"
        + "$"
    );

    // export public function
    return function (url) {
        if (rgHttpUrl.test(url)) {
            return true;
        } else {
            return false;
        }
    };
})();

Tek satırda RegExp:

var rg = /^(http|https):\/\/(([a-zA-Z0-9$\-_.+!*'(),;:&=]|%[0-9a-fA-F]{2})+@)?(((25[0-5]|2[0-4][0-9]|[0-1][0-9][0-9]|[1-9][0-9]|[0-9])(\.(25[0-5]|2[0-4][0-9]|[0-1][0-9][0-9]|[1-9][0-9]|[0-9])){3})|localhost|([a-zA-Z0-9\-\u00C0-\u017F]+\.)+([a-zA-Z]{2,}))(:[0-9]+)?(\/(([a-zA-Z0-9$\-_.+!*'(),;:@&=]|%[0-9a-fA-F]{2})*(\/([a-zA-Z0-9$\-_.+!*'(),;:@&=]|%[0-9a-fA-F]{2})*)*)?(\?([a-zA-Z0-9$\-_.+!*'(),;:@&=\/?]|%[0-9a-fA-F]{2})*)?(\#([a-zA-Z0-9$\-_.+!*'(),;:@&=\/?]|%[0-9a-fA-F]{2})*)?)?$/;

Benzer bir durumda bundan kurtuldum:

someUtils.validateURL = function(url) {
    var parser = document.createElement('a');
    try {
        parser.href = url;
        return !!parser.hostname;
    } catch (e) {
        return false;
    }
};

yani, tarayıcılar sizin için yapabiliyorsa neden tekerleği icat edesiniz? Ancak, elbette, bu yalnızca tarayıcıda çalışacaktır.

tarayıcının tam olarak nasıl yorumlayacağı ayrıştırılmış URL'nin çeşitli bölümleri vardır:

parser.protocol; // => "http:"
parser.hostname; // => "example.com"
parser.port;     // => "8080"
parser.pathname; // => "/path/"
parser.search;   // => "?search=test"
parser.hash;     // => "#hash"
parser.host;     // => "example.com:3000"

Bunları kullanarak, gereksinimlere bağlı olarak doğrulama işlevinizi geliştirebilirsiniz. Tek dezavantajı, göreli URL'leri kabul etmesi ve geçerli sayfa sunucusunun ana bilgisayarını ve bağlantı noktasını kullanmasıdır. Ancak URL'yi parçalardan yeniden bir araya getirerek ve her zaman tam olarak AJAX hizmetinize aktararak kendi avantajınız için kullanabilirsiniz.

Kabul validateURLedilmeyen şey geçersiz URL'dir, örneğin http:\:8883yanlış döndürür, ancak :1234geçerlidir ve http://pagehost.example.com/:1234yani göreceli bir yol olarak yorumlanır .

GÜNCELLEME

Bu yaklaşım artık Chrome ve diğer WebKit tarayıcılarında çalışmamaktadır. URL geçersiz olsa bile, ana bilgisayar adı bir değerle doldurulur, örneğin, adresinden alınır base. Yine de URL'nin parçalarını ayrıştırmaya yardımcı olur, ancak birini doğrulamaya izin vermez.

Olası daha iyi çözümleyici olmayan yaklaşım, var parsedURL = new URL(url)istisnaları kullanmak ve yakalamaktır. Örneğin bkz . URL API . Tüm büyük tarayıcılar ve NodeJS tarafından desteklenir, ancak yine de deneysel olarak işaretlenmiştir.

http://angularjs.org/ adresinde bulduğum en iyi normal ifade

var urlregex = /^(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?$/;

Bu benim için çalıştı:

function validateURL(value) {
    return /^(https?|ftp):\/\/(((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:)*@)?(((\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5])\.(\d|[1-9]\d|1\d\d|2[0-4]\d|25[0-5]))|((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?)(:\d*)?)(\/((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)+(\/(([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)*)*)?)?(\?((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|[\uE000-\uF8FF]|\/|\?)*)?(\#((([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(%[\da-f]{2})|[!\$&'\(\)\*\+,;=]|:|@)|\/|\?)*)?$/i.test(value);
    }

oradan, sadece doğru veya yanlış bir geri almak için işlevi çağırma meselesi var:

validateURL(urltovalidate);

Oldukça eski bir soru olduğunu biliyorum, ancak kabul edilmiş bir cevabı olmadığı için URI.js çerçevesini kullanmanızı öneririm: https://github.com/medialize/URI.js

Bir dene / yakala bloğu kullanarak hatalı URI olup olmadığını kontrol etmek için bunu kullanabilirsiniz:

function isValidURL(url)
{
    try {
        (new URI(url));
        return true;
    }
    catch (e) {
        // Malformed URI
        return false;
    }
}

Tabii ki böyle bir şey dikkate alacaktır "% @" iyi oluşturulmuş göreceli URI olarak ... Ben önermek Yani URI.js okumak API kullanıcı iyi oluşturulmuş girdiğinizden emin olmak için, örneğin, daha fazla denetimleri gerçekleştirmek için mutlak URL şunun gibi yapabilirsiniz:

function isValidURL(url)
{
    try {
        var uri = new URI(url);
        // URI has a scheme and a host
        return (!!uri.scheme() && !!uri.host());
    }
    catch (e) {
        // Malformed URI
        return false;
    }
}

Gibi bir npm paketinde içe aktarın

https://www.npmjs.com/package/valid-url

ve URL'nizi doğrulamak için kullanın.

Son zamanlarda standart olan URL API'yi kullanabilirsiniz . Tarayıcı desteği en iyi ihtimalle yarım yamalaktır, bağlantıya bakın. geçersiz URL'leri new URL(str)atması garantilidir TypeError.

Yukarıda belirtildiği gibi, http://wwwwgeçerli bir URL'dir.

Daha güvenilir bir normal ifade arıyorsanız RegexLib'e göz atın. Muhtemelen ilgileneceğiniz sayfa şu şekildedir:

http://regexlib.com/Search.aspx?k=url

Kişi yazmaya devam ederken gösterilen hata mesajlarına gelince, olayı olarak keydowndeğiştirin blurve ardından kişi bir sonraki öğeye geçtiğinde kontrol edecektir.

var RegExp = (/^HTTP|HTTP|http(s)?:\/\/(www\.)?[A-Za-z0-9]+([\-\.]{1}[A-Za-z0-9]+)*\.[A-Za-z]{2,40}(:[0-9]{1,40})?(\/.*)?$/);

Çözümüm:

function isValidUrl(t)
{
    return t.match(/^(http|https|ftp):\/\/(([A-Z0-9][A-Z0-9_-]*)(\.[A-Z0-9][A-Z0-9_-]*)+)(:(\d+))?\/?/i)

    return (false);
}

Farklı çözümleri karşılaştırmak için harika bir kaynak buldum: https://mathiasbynens.be/demo/url-regex

Bu sayfaya göre, diegoperini'nin tek çözümü tüm testleri geçmektedir. İşte o normal ifade:

_^(?:(?:https?|ftp)://)(?:\S+(?::\S*)?@)?(?:(?!10(?:\.\d{1,3}){3})(?!127(?:\.\d{1,3}){3})(?!169\.254(?:\.\d{1,3}){2})(?!192\.168(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\x{00a1}-\x{ffff}0-9]+-?)*[a-z\x{00a1}-\x{ffff}0-9]+)(?:\.(?:[a-z\x{00a1}-\x{ffff}0-9]+-?)*[a-z\x{00a1}-\x{ffff}0-9]+)*(?:\.(?:[a-z\x{00a1}-\x{ffff}]{2,})))(?::\d{2,5})?(?:/[^\s]*)?$_iuS

Google'da çok sayıda url doğrulayıcısını kontrol ettim ve kimse benim için çalışmıyor. Örneğin, 'aa.com' gibi bağlantılarda geçerli görmek istiyorum. Ben aptalca nokta işareti dizesini kontrol etmeyi seviyorum.

function isValidUri(str) {
  var dotIndex = str.indexOf('.');
  return (dotIndex > 0 && dotIndex < str.length - 2);
}
