HTML文档的字符编码未声明为codeigniter
[英]character encoding of the HTML document was not declared codeigniter
问题描述
My CodeIgniter app has started to a freak error: 
我的CodeIgniter应用程序已经开始出现怪异错误：
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.
In the first visit, the page appears fine, just a message "guimbu" . 在第一次访问时，页面显示正常，只是一条消息“guimbu” 。 If you refresh the page, the error appears until you clear the history of browser. 如果刷新页面，则会在清除浏览器历史记录之前显示错误。 This happens only after second page-view. 这仅在第二次页面查看后发生。 Take a look: http://guimbu.com/soon 看看： http ： //guimbu.com/soon
- I've just opened ALL FILES with Sublime and saved to UTF-8; 我刚刚用Sublime打开了所有文件并保存到UTF-8; twice. 两次。
- I've just tried with all charset meta tags; 我刚试过所有charset元标记;
- This happens with ALL pages, including this simple page; 所有页面都会发生这种情况，包括这个简单的页面
My autoload.php has this: 我的autoload.php有这个：
$autoload['packages'] = array();
$autoload['libraries'] = array('session', 'database', 'firephp', 'auth');
$autoload['helper'] = array('url', 'log_helper', 'api_helper', 'string_helper');
$autoload['config'] = array('ci_opauth', 'rest', 'ci_auth');
$autoload['language'] = array();
$autoload['model'] = array();
How can I debug this problem? 我该如何调试这个问题？
UPDATE: 更新：
@sudhir, thanks for the answer, but I tried this many times. @sudhir，谢谢你的回答，但我多次尝试过。 Actually the source code is just: 实际上源代码只是：
<!DOCTYPE html>
<head>
<title>guimbu</title>
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">
</head>
<body>
guimbu =)
</body>
</html>
And the error persists after second page-view =/ Maybe a problem with sessions? 并且在第二次页面查看后错误仍然存在= /可能是会话有问题？
UPDATE with possibility: 更新可能性：
When I remove session and auth libraries from autoload , the problem doesn't happen. 当我从autoload中删除会话和auth库时，问题不会发生。 WTF? WTF？ auth is a library I made for user authentication. auth是我为用户身份验证而创建的库。

When you refresh that page you get a blank one, if you view source that page you'll see it's blank that is has a number count. 当您刷新该页面时，您会得到一个空白页面，如果您查看该页面的来源 ，您将看到它是空白的，具有数字计数。 My guess is that you're doing something when the page refreshes that sends a white space to the browser. 我的猜测是，当页面刷新时会向浏览器发送一个空白区域。 I can only suggest not to close your files with ?> and let php handle how your scripts will exit/die. 我只能建议不要用?>关闭你的文件，让php处理你的脚本退出/死亡的方式。 There's some whitespace in your code that's causing that. 你的代码中有一些空格导致了这一点。

try adding these in head section of your view: 尝试在视图的head部分添加这些：
<meta content="text/html;charset=utf-8" http-equiv="Content-Type">
<meta content="utf-8" http-equiv="encoding">

In the first lines of Session class constructor, it loads the String helper. 在Session类构造函数的第一行中，它加载String helper。 Yesterday I've created a helper called string_helper.php and this conflict was what crashing application. 昨天我创建了一个名为string_helper.php的帮手，这个冲突就是崩溃的应用程序。
I renamed my string_helper.php file and now everything works fine. 我重命名了我的string_helper.php文件，现在一切正常。
Thanks all! 谢谢大家！
