URLComponents发现无

Question

所以我的条件是，如果URL包含com://******/sendto/webview，那么它应该在我的应用程序内的浏览器中打开，否则它将在Safari中打开。我无法弄清楚我做错了什么？

        if let url = homeObject["deeplink_url"] as? String, url != "" {

            if url.contains("com://******/sendto/webview") {

                if url.contains("?url") {

                    self.fixMalformedURL(url)

                } else {

                    if let urlComponents = URLComponents(url: URL(string: url)!, resolvingAgainstBaseURL: true) {
                        let webViewTitle = urlComponents.queryItems!.filter({ $0.name == "title" }).first
                        let webViewURL = urlComponents.queryItems!.filter({$0.name == "url"}).first

                        let storyboard = UIStoryboard(name: "Main", bundle: nil)
                        let vc = storyboard.instantiateViewController(withIdentifier: "FeaturedWebViewController") as! FeaturedWebViewController
                        vc.webViewTitle = webViewTitle!.value
                        vc.dynamicURL = webViewURL!.value
                        self.navigationController?.pushViewController(vc, animated: true)
                    }
                }

            } else {

                UIApplication.shared.openURL(URL(string: url)!)
            }

        }

您的应用可能会崩溃，因为您尝试过滤＆＃34; title＆＃34;字段，但它提交的URL不存在于url中 这是工作代码，如果url有空格然后删除它

var settings = '../settingsConfig/settings.json';
var file = require(settings)
const SteamTotp = require('steam-totp');
const Discord = require('discord.js');
const configS = require('../settingsConfig/ConfigSammy.json');
const configJ = require('../settingsConfig/ConfigJack.json');
const configB = require('../settingsConfig/ConfigBen.json');

module.exports.run = async (bot, message, args) => {
function myFunc(){
    var JackCode = SteamTotp.getAuthCode(configJ.sharedSecret);
    var BenCode = SteamTotp.getAuthCode(configB.sharedSecret);
    var SammyCode = SteamTotp.getAuthCode(configS.sharedSecret);

    var codess = new Discord.RichEmbed()
        .addField("__**Bens Code:**__", BenCode)
        .addField("__**Jacks Code:**__", JackCode)
        .addField("__**Sammys Code:**__", SammyCode)
        .setColor(0x00FF00)
        message.author.send(codess)
}
new myFunc();
};

module.exports.help = {
    name: "codes"
}
