在Firefox和Internet Explorer中，url编码的行为不同 [英] url encode behaving differently in Firefox and Internet Explorer
问题描述
我想将用户的条目发送到google的地理编码API。在这样做的时候，我发现了一个问题。
当我通过我的脚本将用户输入（例如köln+ Germany）发送到Firefox中的api时，它的效果非常好。在Internet Explorer中，它不起作用。
I want to send a user's entry to google's geocode API. In doing so, I detected a problem. When I send the user input (e.g. "köln+Germany") through my script to the api in Firefox it works great. In Internet Explorer however it's not working.
以下是我的代码的豁免足以显示问题：
Here's the exempt of my code that's enough to show the problem:
header('Content-type: text/html; charset=UTF-8');
header('Cache-Control: no-cache, must-revalidate');
$loc = urlencode($_GET['loc']);
echo $address = "http://maps.googleapis.com/maps/api/geocode/json?address=$loc&sensor=false";
Firefox中的输出（$ address）是： http://maps.googleapis.com/maps/api/geocode/json？ address = k％C3％B6ln + Germany& sensor = false （works！）
The output ($address) in Firefox is: http://maps.googleapis.com/maps/api/geocode/json?address=k%C3%B6ln+Germany&sensor=false (works!)
Internet Explorer中的相同： http://maps.googleapis.com/maps/api/geocode/ json？address = k％F6ln + Germany& sensor = false （返回INVALID_REQUEST）
The same in Internet Explorer is: http://maps.googleapis.com/maps/api/geocode/json?address=k%F6ln+Germany&sensor=false (returns "INVALID_REQUEST")
您可以看到ö的编码区别。在Firefox中，它是％C3％B6，在IE中是k％F6。
如果我用户输入k％C3％B6ln + Germany，它的工作原理就像Internet Explorer中的魅力。
You can see the difference in the encoding of the ö. In Firefox it's %C3%B6, in IE it's k%F6. If I make the user input "k%C3%B6ln+Germany" to begin with, it works like a charm in Internet Explorer also.
我用PHP确保我的特殊字符的转换在Internet Explorer中与Firefox相同。所以ö=％C3％B6而不是ö= k％F6
How can I with PHP ensure that the conversion of my special characters is the same in Internet Explorer as in Firefox. So ö = %C3%B6 instead of ö = k%F6
非常感谢！

推荐答案
这是一个编码问题，Firefox中的默认编码是UTF-8，而在IE中它是一些ISO-XXXX- X，尝试设置
This is an encoding Problem, the default encoding in Firefox is UTF-8 while in IE it is some ISO-XXXX-X, try to set
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
< head> ...< / head> ; 这将将编码设置为UTF-8，因此IE将对Firefox的字符串进行urlencode的编码，因此会生成工作请求。
in Your HTML -<head>...</head> this will set the encoding to UTF-8, so IE will urlencode the string like Firefox did and therefore produces a working request.
顺便说一下，如果你希望这个链接成为一个链接，你应该提供一个html页面，所以你应该
and by the way, you should deliver a html page if you want that to be a link so you should
echo '<html><head><meta http-equiv="content-type" content="text/html; charset=UTF-8"></head><body>';
在回显< a href = ...> / code>和
before you echo the <a href=...> and
echo '</body></html>';
之后。
这样IE将使用给定的UTF-8编码显示链接。
That way IE will use the given UTF-8 encoding on displaying the link.
它可能看起来像如果它没有这种东西可以工作，那么IE会解码给定的< a href = ...> ，猜测它是一个链接，然后使自己的html-围绕它的头体显示它 - 其中包括一个< meta http-equiv =content-typecontent =text / html; charset = ISO-XXXX-X> code>
It might seem as if it would work without that stuff, butt then IE decodes the given <a href=...> , guesses it is a link and then makes his own html-head-body around it to display it - which then includes a <meta http-equiv="content-type" content="text/html; charset=ISO-XXXX-X"> instead.
如果您只是将链接通过AJAX传递到已加载的页面，请确保此页面包含所提及的元标记。
If you just pass the link to via "AJAX" to a page already loaded make sure that this page contains the mentioned meta-tag.
