1、字符串中是否包含某个指定的url
checkInviteUrl(text) {
var isLega = true
if (text.indexOf("https://meteora.xyz/#/t/") !== -1) {
let str = text.slice(-10)
for(var idx =0;idx < str.length;idx++) {
var asc = str.charCodeAt(idx)
if (!(asc >= 48 && asc <= 57 || asc >= 65 && asc <= 90 || asc >= 97 && asc <= 122)) {
isLega = false;
}
}
} else {
isLega = false
}
return isLega
}
2、字符串中是否包含url
checkUrlWithString(str_url){
var strRegex = "((https|http|ftp|rtsp|mms)?://)"
+ "(([0-9a-z_!~*'().&=+$%-]+: )?[0-9a-z_!~*'().&=+$%-]+@)?" //ftp的user@
+ "(([0-9]{1,3}\.){3}[0-9]{1,3}" // IP形式的URL- 199.194.52.184
+ "|" // 允许IP和DOMAIN(域名)
+ "([0-9a-z_!~*'()-]+\.)*" // 域名- www.
+ "([0-9a-z][0-9a-z-]{0,61})?[0-9a-z]\." // 二级域名
+ "[a-z]{2,6})" // first level domain- .com or .museum
+ "(:[0-9]{1,4})?" // 端口- :80
+ "((/?)|" // a slash isn't required if there is no file name
+ "(/[0-9a-z_!~*'().;?:@&=+$,%#-]+)+/?)";
var re = new RegExp(strRegex);
if (re.test(str_url)){
return true
} else {
return false
}
}
3、提取字符串中的url
getUrlWithString(s) {
// var reg = "(http://|https://)((w|=|?|.|/|&|-)+)";
var reg = "(https?|http|ftp|file)://[-A-Za-z0-9+&@#/%?=~_|!:,.;]+[-A-Za-z0-9+&@#/%=~_|]";
s = s.match(reg);
return(s)
}
