php - kohana 3 路由在某些情况下失败

Question

我在 Kohana 3 路线和/或其他导致我的路线失败的问题上遇到了非常烦人的问题。

相关路线定义为:

Route::set('module', '(<lang>/)<controller>(/<action>(/<id>))', array('lang' => $lang_options, 'controller' => '(docrepo|calendar|maps|forum)'))
->defaults(array(
        'controller' => 'docrepo',
        'lang' => DEFAULT_LANG,
        'action' => 'index',
));

• 这条路线似乎适用于几乎所有情况
• 导致我出现问题的具体情况是:/calendar/save
• 直接从 Safari 或 IE 中的标签访问/calendar/save 路径始终有效(例如 https://my.site.com/calendar/save )
• 直接从 Firefox 中的选项卡访问/calendar/save 路径有时有效(例如 https://my.site.com/calendar/save )
• 在任何浏览器中从 AJAX 访问/calendar/save 路由总是失败并且页面最终被我的 catch-all 路由捕获并发送到 404 页面，catch-all 路由是如下所示
• 访问同一 Controller 和路由的另一个操作始终有效(即使通过 AJAX)(例如 https://my.site.com/calendar/edit 在所有浏览器中直接或通过 AJAX 都可以正常工作)

包罗万象的路线是:

Route::set('catch_all', '<path>', array('path' => '(|.+)'))
->defaults(array(
    'controller' => 'base',
    'action' => '404',
));

我的 apache 日志中没有错误，因为一切都按照 apache 和 php 运行。

我的 Kohana 日志中没有错误，因为一切都按照 Kohana 进行。

我向 404 页面添加了一些调试代码，以下是对日历/保存的 ajax 调用的输出:

这是在正在运行的页面上运行的相同调试代码，您可以看到正确的路由显示为匹配的:

我调用保存函数的 JavaScript 代码是:

calendar.save_event = function() {
    var save_url = URL_ROOT + '/calender/save?' + TIME_STAMP;
    // prepare the data string
    var inputs = [];
    // get all the form elements and add them to the parameter string to be sent via ajax
    $('#dialog_form :input').each( function() {
        // only add if not a checkbox, or if it is a checkbox, then it must be checked
        if ( ! $(this).is(':checkbox') || $(this).is(':checked')) {
            inputs.push(this.name + '=' + encodeURIComponent(this.value));
        }
    });
    alert('try saving by posting to: ' + save_url);
    // try to save the record
    $.ajax({
        type: 'POST',
        data: inputs.join('&'),
        url: save_url,
        dataType: 'json',
        success: function(data, text_status) {
            if (data['status'] == 1) {
                alert(data['status_message']);
                // add the event to the calendar
                // todo add actual event details
                $("#day_number" + $('#initial_day_number').val()).append("new event");
                // close the dialog box
                $('#dialog_form').dialog("close");
            } else {
                alert('The event could not be saved at this time.  Please try again later. (' + data['status_message'] + ')');
            }
        },
        error: function(xml_request, text_status, error_thrown) {
            alert('The event could not be saved at this time.  Please try again later. (' + text_status + ')');
        }
    });
}

在上面的代码中，URL_ROOT 设置正确。我添加了这个，因为我最初使用相对引用“/calendar/save”，但两者都不起作用。我还添加了 TIME_STAMP GET 参数，该参数只是当前的 UNIX 时间戳(php 中的 time())，以查看这是否是缓存问题。这也没有任何区别。

根据调试代码，您可以看到调用将转到正确的 URL，只是由于某种原因未匹配。

任何帮助将不胜感激。

谢谢，克雷格

您是复制/粘贴此内容还是输入的？因为看起来在错误的 ajax 代码中，您输入了 calender 而不是 calendar。这也显示在 404 调试信息中。
