Question

使用CodeIgniter 1.7开发我的Web应用程序时，仅使用Chrome浏览器打开时出现错误 ERR_RESPONSE_HEADERS_TOO_BIG 。我尝试了所有其他浏览器，不会发生错误。

刷新错误页面后，我可以正常打开页面。我尝试从谷歌搜索，从2009年到现在，Chrome用户似乎发生了这个错误。

这是我的控制器代码：

function search_daily_sales_summary_view()
{
    if(!($this->session->userdata('DAILY_SALES_SUMMARY'))){
        $this->session->set_flashdata('error', 'You dont have the permission to access that page.');
        redirect('login/home');
    }

    $this->load->model('currency_model');
    $this->load->model('bill_model');

    $data = array();

    $report = array();

    if($query = $this->currency_model->list_currency())
    {
        foreach ($query as $row) {

        $currencyid = $row->CURRENCY_ID;
        $currencycode = $row->CURRENCY_CODE;

        if($buyData = $this->bill_model->calculate_buy($currencyid))
        {
            $totalbuy = $buyData->total_from_amount;
            $totalbuy_rate = $buyData->rate;

            if($buyData->total_from_amount=='')
            {
                $totalbuy = 0.00;
            }

            if($buyData->rate=='')
            {
                $totalbuy_rate = 0.00;
            }
        }
        else
        {
            $totalbuy = 0.00;
            $totalbuy_rate = 0.00;
        }

        if($sellData = $this->bill_model->calculate_sell($currencyid))
        {
            $totalsell = $sellData->total_from_amount;
            $totalsell_rate = $sellData->rate;

            if($sellData->total_from_amount=='')
            {
                $totalsell = 0.00;
            }

            if($sellData->rate=='')
            {
                $totalsell_rate = 0.00;
            }

        }
        else
        {
            $totalsell = 0.00;
            $totalsell_rate = 0.00;
        }

        $report[] = array("currency"=>$currencycode, "buy"=>$totalbuy, "buyrate"=>$totalbuy_rate, "sell"=>$totalsell, "sellrate"=>$totalsell_rate);

        }

        $data['records'] = $report;

    }

    $this->load->model('company_model');
    if($query = $this->company_model->list_company())
    {
        $data['company_list'] = $query;
    }

    $this->load->model('branch_model');
    if($this->input->post('company'))
    {
        $companyid = $this->input->post('company');

        if($query = $this->branch_model->view_company_branch($companyid))
        {
            $data['branch_list'] = $query;
        }
    }
    else
    {
        if($query = $this->branch_model->list_branch())
        {
            $data['branch_list'] = $query;
        }
    }

    $this->load->view('report/daily_sales_summary', $data);

}

如何解决这个问题？

Answer 1

CI将会话存储在cookie中。如果你在cookie中存储太多，就会出错。

将CodeIgniter设置为使用数据库会话，或将其保存到文件中。

Answer 2

Saving Session Data to a Database

CREATE TABLE IF NOT EXISTS  `ci_sessions` (
    session_id varchar(40) DEFAULT '0' NOT NULL,
    ip_address varchar(16) DEFAULT '0' NOT NULL,
    user_agent varchar(120) NOT NULL,
    last_activity int(10) unsigned DEFAULT 0 NOT NULL,
    user_data text NOT NULL,
    PRIMARY KEY (session_id),
    KEY `last_activity_idx` (`last_activity`)
);

Note: By default the table is called ci_sessions, but you can name it anything you want as long as you update the application/config/config.php file so that it contains the name you have chosen. Once you have created your database table you can enable the database option in your config.php file as follows:

$config['sess_use_database'] = TRUE;

Once enabled, the Session class will store session data in the DB.

Make sure you've specified the table name in your config file as well:

$config['sess_table_name'] = 'ci_sessions';

Note: The Session class has built-in garbage collection which clears out expired sessions so you do not need to write your own routine to do it.
