Question

我的电子邮件有问题，html是好的，但是当我打开它们时，文本中的错误和链接中的某些字符变为= =

每个图像和链接甚至文本都是borken 我认为它与{unwrap}有关，但没有帮助

这是config / email.php

$config['email_notification']['protocol'] = 'smtp';
$config['email_notification']['smtp_host'] = 'smtp.live.com';
$config['email_notification']['smtp_user'] = 'xxxxx';
$config['email_notification']['smtp_pass'] = 'xxxxxxx';
$config['email_notification']['smtp_port'] = '587';
$config['email_notification']['mailtype'] = 'html';
$config['email_notification']['charset'] = 'utf-8';
$config['email_notification']['wordwrap'] = false;
$config['email_notification']['smtp_crypto'] = 'tls';

这是控制器

 $this->load->library('email');



    $this->email->initialize($this->config->item('email_notification'));
    $this->email->subject('Email Test');

    $this->email->set_newline("\r\n");
    $this->email->from('xxxxxx'); // change it to yours
    $this->email->to('xxxxx');
    $this->email->subject('Email Test');

    $data=array(
        'site_name'=>'tralalalal',
        'user_id'=>'123131',
        'new_email_key'=>'123131',
        'activation_period'=>'123131',
        'email'=>'123131',
        'title'=>'123131',

    );
    $this->email->message($this->load->view('email/activate_account/en',$data,true));

Answer 1

我找到了答案，所以如果有人有同样的问题

有原因

该标准对于数量有两个限制   一行中的字符。每行字符必须不超过
  998个字符，不应超过78个字符，不包括
  CRLF。

998字符限制是由于许多限制   发送，接收或存储Internet消息的实现   格式化消息，无法处理超过998个字符   在一条线上。接收实现将很好地处理   为了鲁棒性，一行中任意大量的字符   清酒。但是，有很多实现（in   符合[RFC2821]的运输要求）   接受包含超过1000个字符的消息，包括   每行CR和LF，对于不执行的实现很重要   创造这样的信息。

更为保守的78字符建议是适应   显示这些的用户界面的许多实现   可能截断或灾难性地包装的信息   尽管有这样的事实，但每行超过78个字符   实现不符合本文的意图   规范（和[RFC2821]的规范，如果它们实际上导致
  信息丢失）。同样，即使有这种限制   消息，它是显示消息
的实现的障碍

这是您更改代码以覆盖此限制的位置系统/库/ email.php

原单

protected function _prep_quoted_printable($str, $charlim = '')
{
    // Set the character limit
    // Don't allow over 76, as that will make servers and MUAs barf
    // all over quoted-printable data
    if ($charlim == '' OR $charlim > '76')
    {
        $charlim = '76';
    }

QUICK FIX :)

protected function _prep_quoted_printable($str, $charlim = '')
{
    // Set the character limit
    // Don't allow over 76, as that will make servers and MUAs barf
    // all over quoted-printable data
    if ($charlim == '' OR $charlim > '76')
    {
        $charlim = '200';
    }

Answer 2

我认为问题出在_prep_quoted_printable函数中。幸运的是，从v5.3开始，这个函数的本机PHP版本

我能够通过使用PHP本机函数quoted_printable_encode替换Email类中的_prep_quoted_printable实例来解决类似问题。

这相当于我的_build_message（），如下所示：

    /**
 * Build Final Body and attachments
 *
 * @access  protected
 * @return  void
 */
protected function _build_message()
{
    if ($this->wordwrap === TRUE  AND  $this->mailtype != 'html')
    {
        $this->_body = $this->word_wrap($this->_body);
    }

    $this->_set_boundaries();
    $this->_write_headers();

    $hdr = ($this->_get_protocol() == 'mail') ? $this->newline : '';
    $body = '';

    switch ($this->_get_content_type())
    {
        case 'plain' :

            $hdr .= "Content-Type: text/plain; charset=" . $this->charset . $this->newline;
            $hdr .= "Content-Transfer-Encoding: " . $this->_get_encoding();

            if ($this->_get_protocol() == 'mail')
            {
                $this->_header_str .= $hdr;
                $this->_finalbody = $this->_body;
            }
            else
            {
                $this->_finalbody = $hdr . $this->newline . $this->newline . $this->_body;
            }

            return;

        break;
        case 'html' :

            if ($this->send_multipart === FALSE)
            {
                $hdr .= "Content-Type: text/html; charset=" . $this->charset . $this->newline;
                $hdr .= "Content-Transfer-Encoding: quoted-printable";
            }
            else
            {
                $hdr .= "Content-Type: multipart/alternative; boundary=\"" . $this->_alt_boundary . "\"" . $this->newline . $this->newline;

使用Outlook封闭环境，不希望发送到另一个邮件客户端。

相似的结果，但是不同版本的codeigniter。我有一个wrapchars变量可以更改它。问题是它在_prep_quoted_printable中使用了硬编码76。我将76更改为

    $this->wrapchars

一切都变得美好。
