我在iOS 15.5上的cordova项目遇到了问题。现在我正在尝试验证一个启用了标准身份验证的用户在IIS上的登录。

<?php

// Prüfen, ob Benutzeranmeldung über IIS erfolgt ist
if (!isset($_SERVER['PHP_AUTH_USER'])) {
    header("HTTP/1.1 401 Unauthorized");
    exit;
}

// OK zurückgeben
header("Content-Type: application/json");
echo '{"login":"ok"}';
?>

下面是来自iPhone的javascript请求：

function benutzeranmeldungPruefen() {

    var loginString = eingabeBenutzername + ":" + eingabeKennwort;
    var loginStringBase64 = "Basic " + btoa(loginString); // String für Header in Base64 codieren

    
    // Login-Header definieren
    $.ajaxSetup({
        headers: { "Authorization": loginStringBase64 },
            timeout: 10000
    });
    
    var servername = localStorage.getItem("Server");
    var port = localStorage.getItem("Port");
    var https = localStorage.getItem("Https");
 
    // HTTP-GET-Request erstellen
    var get = $.get( https+"://"+servername+":"+port+"/logincheck.php");

    get.done(function( data ) {
        
        // Prüfen, ob Anmeldung erfolgreich war
        if (data["login"] == "ok") {
            
            localStorage.setItem("Benutzer", eingabeBenutzername);
            localStorage.setItem("Kennwort", eingabeKennwort);
            
        }
        else {
            // Grafische Anpassungen und Protokoll
            document.getElementById("statusLogin").innerHTML += "<br />Authentifizierung fehlgeschlagen.";
            document.getElementById("buttonLogin").setAttribute("style", "display:block;");
            
        }
        
        // Grafische Anpassungen
        document.getElementById("loadingLogin").setAttribute("style", "visibility:hidden;");
        //document.getElementById("loadingLogin").setAttribute("style", "display:none;");
        
        
    });

    get.fail(function() {
        // Grafische Anpassungen und Protokoll
        document.getElementById("buttonLogin").setAttribute("style", "display:block;");
        document.getElementById("loadingLogin").setAttribute("style", "visibility:hidden;");
        $("#seiteErsteinrichtung").removeClass("loading");
        alert( "Fehler beim Überprüfen der Zugangsdaten!" );
    })
    
}

如果我构建应用程序并在我的iPhone上运行它，我会在使用Safari进行调试时遇到此错误：

[Error] Preflight response is not successful. Status code: 401
[Error] XMLHttpRequest cannot load https://192.168.178.10/logincheck.php due to access control checks.
[Error] Failed to load resource: Preflight response is not successful. Status code: 401 (logincheck.php, line 0)

然后寻找标题，这就是我得到的：

no Response-Header

我已经设置了所有的标题，我可以找到在线在我的网页配置文件可悲的是没有成功：

<?xml version="1.0" encoding="utf-8"?>

    <system.web>
        <customErrors mode="Off" />
    </system.web>

            </customHeaders>

如果我从请求中删除Authorization头，我至少会从服务器得到一个答案：

我不知道是什么导致这个问题或如何解决它。我试图解决这个问题没有近3天，我找不到任何东西。我真的需要帮助。
