Javascript $.post到Codeigniter控制器/方法404页未找到

我已经开发了一个Codeigniter原型应用程序，并在开发阶段与Godaddy.com一起托管，用于测试目的，没有问题。该应用程序使用javascript、jquery、HTML5、CSS和PHP（Codeigniter框架）的组合。本周，我将应用程序转移到客户机服务器，遇到了许多配置问题，但最终遇到了麻烦

客户端使用PHP5在新的Linux/Apache2服务器上重新安装。mod_rewrite已启用，allowoverride设置为all。Apache2设置（每个客户端）为

我的.htaccess脚本（自本期发行以来，我尝试了许多不同的.htaccess版本）

我的javascript代码，用于将序列化表单数据发布到PHP页面

        $.post('login_ctrl/authenticateuserlogon', $formData, function($responseData)
        {   
            $userAuthentication=$responseData.userAuthentication;

            if ($userAuthentication=='success')
            {
                window.location.href = "student_portal_ctrl";
            }
            else
            {                       
                $('#loginErrDiv').text('Username or Password is incorrect - Please try again.');
                return;
            }

        });         

我的codeigniter文件结构是

-root /
       /CI
        /application
        /system
        /index.php
        /license.txt
        /.htaccess

当我发布到此控制器/方法时，浏览器输出

----编辑---

抱歉，忘记包含我的config.php设置，它们在这里

 $config['base_url'] = '';
 $config['index_page'] = '';
 $config['uri_protocol']    = 'AUTO'; //I have tested the app using all of codeigniters 
                                      //default URI Protocols

----编辑#2---

这是接收404错误的控制器上的方法

    //AUTHENTICATE USER LOGIN FUNCTION
public function authenticateuserlogon()
{
    //SETTING $FORMDATA TO SERIALIZED POST DATA
    $formData = $this->input->post();

    //Sets the Method for the login_mdl
    $modelMethod=$formData['modelMethod'];

    //LOADING USER AUTHENTICATION LOGIN MODEL
    $this->load->model('login_mdl');


    //SENDING FORMDATA TO MODEL AND RETURING DATA TO $RESPONSEDATA
    $responseData = array();
    $responseData = $this->login_mdl->$modelMethod($formData);

    //OUTPUTTING JSON RESPONSE DATA BACK TO JAVASCRIPT          
    $this->output->set_output(json_encode($responseData));          
}

使用此

.htaccess

，它经过我的测试，工作正常

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /CI/

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.

    ErrorDocument 404 /index.php
</IfModule>

打开

http://yourip/CI

？@Deepak当我打开。。。浏览器正确加载my index.php，它加载默认登录控制器，它加载我的登录视图。当我点击登录表单上的submit按钮（调用上面的javascript post代码）时，就是当我收到404 not found错误时，您是否尝试在url中添加index.php。只是为了验证tat是否有效。@Deepak也正确加载了站点。当您执行65.44.222.164/CI/index.php/login\u ctrl/authenticateuserlogon时，我已经更新了代码和.htaccess。现在，当我提交表单时，我收到的是“NetworkError:500内部服务器错误-”而不是404 Not Found erroryes，这意味着您的代码中有错误。请检查您的apache错误日志扫描您发布的

authenticateuserlogon

方法？首先，感谢您的耐心，因为我快疯了。：）以下是我的apache错误日志，其中500个错误[debug]mod_deflate.c（615）：[client 98.154.88.186]Zlib:Compressed 1166-527:URL/CI/index.php[debug]mod_deflate.c（615）：[client 98.154.88.186]Zlib:Compressed 1166-527:URL/CI/index.php[debug]mod_deflate.c（615）：[client 98.154.88.186]Zlib:Compressed 92651 to 32770:URL/CI/js/jquery-1.9.1.min.js，referer:[debug]mod_deflate.c（615）：[client 98.154.88.186]Zlib:Compressed 3089 to 1061:URL/CI/css/login.css，referer:[debug]mod_deflate.c（615）：[client 98.154.88.186]Zlib:Compressed 2638 to 1111:URL/CI/js/login/login.js，referer:
