尝试使用https://example.com/service通过浏览器访问服务我获得了基本的身份验证对话框.

将URL更改为https：// username：password@example.com/service可以轻松绕过该URL.

尝试使用Ajax执行相同操作始终会导致401 Unauthorized：

$.ajax({
    url: 'https://username:password@example.com/service',// rest repeats
    type: "GET",async: true,success: function(text) { alert('success'); },error: function (text) { alert('error') },complete: function(text) { alert('complete'); }
});

$.ajax({
    url: 'https://example.com/service',username: username,password: password,// snip repeat
});

$.ajax({
    url: 'https://example.com/service',beforeSend: function(xhr) {
        xhr.setRequestHeader("Authorization","Basic "
            + btoa(username + ":" + password));
    },// snip repeat
});
