JavaScript를 사용하여 URL 유효성 검사 시도 중
URL을 확인하고 메시지를 표시하고 싶습니다.아래는 제 코드입니다.
$("#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;
}
}
는 이제 이 URL 에도 로입니다 true 되고와 입니다."http://wwww".
당신의 제안에 감사드립니다.
누군가 Jquery Validation 플러그인을 언급했습니다. URL만 검증하고 싶다면 오버킬로 보입니다. 플러그인의 regex 행은 다음과 같습니다.

regex를 사용하여 URL을 파싱하는 것은 실용적이지 않습니다.RFC1738 규칙을 완전히 구현하면 (가능하다고 가정할 때) 엄청나게 긴 정규식이 발생합니다.확실히 현재 표현식은 유효한 URL을 많이 실패하고 잘못된 URL을 전달합니다.
대신:
a. 실제 규칙을 따르는 적절한 URL 파서를 사용합니다. (JavaScript용 파서는 모릅니다. 오버킬일 수 있습니다.서버 쪽에서도 할 수 있다)거나,
b. 선행 또는 후행 공간을 모두 잘라낸 다음, 선호하는 구성 중 하나가 전면에 있는지 확인하고(일반적으로 'http://' 또는 'https://'), 그 위치에 그대로 둡니다. 또는,
c. URL을 사용하여 서버 측에서 HTTP HEAD 요청을 전송하는 등 마지막에 무엇이 있는지 확인하려고 시도합니다.404 또는 연결 오류가 발생하면 잘못된 것일 수 있습니다.
url이 " http://wwwww"와 같은 경우에도 true로 반환됩니다.
음, 그것은 확실히 완벽하게 유효한 URL입니다.
'wwww'와 같은 호스트 이름이 실제로 존재하는지 확인하려면 DNS에서 찾아보는 수밖에 없습니다. 다시 말씀드리지만 서버측 코드입니다.
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);
}
다음과 같은 URL의 경우 true를 반환할 수 있습니다.

http와 https URL을 확인하기 위해 rfc1738과 rfc3986에 URL validation function base도 작성하였습니다.저는 이 모듈을 더 잘 유지하고 자신의 요구사항에 맞게 조정할 수 있도록 하려고 노력합니다.
이 게시물의 끝에 한 줄에 있는 RegExp가 표시됩니다.
RegExp는 일부 국제 도메인 또는 IPv4 번호가 포함된 HTTP 및 HTTPS URL을 허용합니다.IPv6는 아직 지원되지 않습니다.
window.isValidURL = (function() {// wrapped in self calling function to prevent global pollution

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

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_path + ")?"

+ ")?"
+ "$"
);
// export public function
return function (url) {
if (rgHttpUrl.test(url)) {
return true;
} else {
return false;
}
};
})();
RegExp를 한 줄로 표시:
var rg = /^(http|https):\/\/(([a-zA-Z0-9$\-_.+!*'(),;:&=]|%[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})*)?)?$/;
비슷한 상황에서 저는 이것을 모면했습니다.
someUtils.validateURL = function(url) {
var parser = document.createElement('a');
try {
parser.href = url;
return !!parser.hostname;
} catch (e) {
return false;
}
};
즉, 브라우저가 당신을 위해 그것을 할 수 있다면 왜 바퀴를 발명합니까?하지만 물론 이것은 브라우저에서만 작동합니다.
구문 분석된 URL에는 브라우저가 정확히 해석하는 방식으로 다양한 부분이 있습니다.
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"
이를 사용하면 요구사항에 따라 검증 기능을 향상시킬 수 있습니다.유일한 단점은 상대적인 URL을 허용하고 현재 페이지 서버의 호스트와 포트를 사용한다는 것입니다.그러나 부품에서 URL을 재조립하여 항상 AJAX 서비스에 전체를 전달함으로써 자신의 이익을 위해 사용할 수 있습니다.
.validateURL하지 않습니다.:예 URL)입니다다:는http:\:8883만,:1234다로 됩니다.http://pagehost.example.com/:1234상대적인 경로로서

이 접근 방식은 더 이상 Chrome과 다른 웹킷 브라우저에서는 작동하지 않습니다. 않은 에도 호스트 은 URL다:값)에서base 분석하는 는 도움이 을 검사하는 URL의 일부를 구문 분석하는 데는 도움이 되지만 URL의 유효성을 검사하는 것은 허용되지 않습니다.

함수를 호출하여 참 또는 거짓을 반환하는 문제가 있습니다.
validateURL(urltovalidate);
꽤 오래된 질문이라는 것을 알고 있지만, 어떤 수용된 답변도 없기 때문에, URI.jsframework: https://github.com/medialize/URI.js 를 사용하는 것을 제안합니다.
try/catch 블록을 사용하여 잘못된 형식의 URI를 확인할 수 있습니다.
function isValidURL(url)
{
try {
(new URI(url));
return true;
}
catch (e) {
// Malformed URI
return false;
}
}
물론 "%@" 같은 것을 잘 형성된 상대 URI로 간주할 것입니다.따라서 URI.js API를 읽어 더 많은 검사를 수행할 것을 제안합니다. 예를 들어 사용자가 잘 형성된 절대 URL을 입력했는지 확인하고 싶다면 다음과 같이 수행할 수 있습니다.
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;
}
}
URL API는 URL 문자열의 구조를 검증하는 데 사용할 수 있습니다.
잘못된 URL 문자열을 개체에 직렬화하려고 하면 오류가 발생합니다.이를 도우미 함수로 추상화할 수 있습니다(아래의 스크립트 스니펫).
function isValidURL(URL: string) : boolean {
try {
new URL(string);
return true;
} catch (err) { return false; }
}
isValidURL('https://www.google.com'); // returns true
isValidURL('localhost:3000'); // returns true
isValidURL('not-a-valid-url'); // returns false
isValidURL('google.com'); // returns false (see footnote)
HTTP/웹 링크가 유효하기를 엄격하게 원한다면 반환문에 조건을 추가하기만 하면 됩니다.
...
const url = new URL(string);
return url.protocol === 'https:' || url.protocol === 'http:';
...
물론 이러한 접근 방식에는 몇 가지 주의 사항이 있습니다.
- Internet Explorer에서 URL API를 지원하지 않습니다(폴리필로 수정 가능).
- 추가적인 검사가 없으면 프로토콜이나 포트가 없는 URL이 잘못된 것으로 표시됩니다(예: google.com 은 유효하지 않지만 google.com:3000 은 OK).일부 사용 사례의 경우 의도하지 않은 동작일 수 있습니다.
다음과 같은 npm 패키지로 가져오기

URL을 확인하는 데 사용합니다.
최근 표준이 된 URL API를 사용하시면 됩니다.브라우저 지원은 기껏해야 대략적일 뿐입니다. 링크를 참조하십시오.new URL(str)됩니다를 됩니다.TypeError유효하지 않은 URL의 경우.

나는 구글에서 url validator를 많이 확인했는데 아무도 나를 위해 일하는 사람이 없습니다.예를 들어 'aa.com '과 같은 링크에서 유효한 것을 보고 싶습니다.나는 문자열의 점 표시를 위한 바보 같은 체크를 좋아합니다.
function isValidUri(str) {
var dotIndex = str.indexOf('.');
return (dotIndex > 0 && dotIndex < str.length - 2);
}
문자열의 시작과 끝에 머물러서는 안됩니다(지금은 문자가 하나인 최상위 도메인 이름이 없습니다).

이 정규 표현은 확장될 수 있지만, 이미 복잡하고 충분히 긴 표현입니다.또한 "100% 정확성"이나 "버그 프리(bug free)"가 될 것이라고 장담할 수는 없지만, 모든 계획에 대해 URI를 정확하게 검증해야 합니다.
이 정규식은 매우 광범위한 URI를 검증하기 때문에 방식별 요구사항에 대한 추가 검증을 수행하거나 URI 정규화를 수행해야 합니다.
편집해 보십시오.isValidURL기능은 다음과 같습니다.
function isValidURL(url) {
var encodedURL = encodeURIComponent(url);
var isValid = false;
$.ajax({
url: "http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22" + encodedURL + "%22&format=json",

return isValid;

이렇게 하면 효과가 있을 겁니다.
