[英]How to prevent incoming UTF-8 content from being re-encoded as UTF-16 when using jquery.validation and XRegexp?
I'm building a form that uses JQuery.Validator with XRegexp to clean input fields before they are submitted to the server (which also validates all incoming posts) but I'm having a little bit of trouble posting the content back to the server. 我正在构建一个将JQuery.Validator和XRegexp一起使用的表单,以在将输入字段提交给服务器之前清理输入字段(这还将验证所有传入的帖子),但是我有点麻烦将内容发布回服务器。
If I post a UTF-8 string like this: Русский日本語fdsffsfsa 如果我发布这样的UTF-8字符串: Русский日本语fdsffsfsa
to the form below: 到以下表格:
<form id="xyzzyForm">
<input id="xyzzy" name="xyzzy" type="text" />
<button type="submit">Submit</button>
</form>
my JQuery/Validate/XRegExp POST's the string as UTF-16: xyzzy=%D0%A0%D1%83%D1%81%D1%81%D0%BA%D0%B8%D0%B9%E6%97%A5%E6%9C%AC%E8%AA%9Efdsffsfsa 我的JQuery / Validate / XRegExp POST的字符串为UTF-16: xyzzy =%D0%A0%D1%83%D1%81%D1%81%D0%BA%D0%B8%D0%B9%E6%97%A5 %E6%9C%AC%E8%AA%9Efdsffsfsa
I know from German Rumm's response on this post Why is jQuery POSTing in UTF-16? 我从德国人Rumm对此帖子的回复中了解到, 为什么UTF-16中使用jQuery POST ? that the problem was coming from escape(), but I'm not using it as you can see from my script below:
问题出在escape(),但我没有使用它,如下面的脚本所示:
<script>
$.validator.addMethod(
"regex",
function(value, element, regexp) {
var re = new XRegExp(regexp);
return this.optional(element) || re.test(value);
},
"Please check your input."
);
$(document).ready(function() {
$("#xyzzyForm").validate({
rules: {
xyzzy: {
required: true,
minlength: 8,
maxlength: 32,
regex: '^[\\p{L}\\p{M}*+\\p{N}]*$'
}
},
messages: {
xyzzy: {
required: "Please enter your xyzzy.",
maxlength: "The xyzzy field only accepts between 8-32 characters.",
minlength: "The xyzzy field only accepts between 8-32 characters.",
regex: "The xyzzy field contains invalid characters. This field only accepts letters and/or numbers."
}
},
submitHandler: function(form) {
var request;
if (request) request.abort();
var $inputs = $(form).find("input, select, textarea, button");
var serializedData = $(form).serialize();
$inputs.prop("disabled", true);
request = $.ajax({
url: "./xyzzy-ajax.php",
cache: false,
type: "post",
contentType: "application/x-www-form-urlencoded; charset=utf-8",
data: serializedData
});
// Prevent default posting of form.
return false;
}
});
});
</script>
Any idea where the re-encode to UTF-16 is occurring in this case? 您是否知道在这种情况下会在哪里重新编码为UTF-16?
Ok I figured out the problem, little embarrassed to say I was led astray but comments regarding JQuery UTF-8 content being encoded to UTF-16 in another post but that wasn't the problem. 好的,我弄清楚了这个问题,不好意思说我误入歧途,但是在另一篇文章中,有关将JQuery UTF-8内容编码为UTF-16的评论却不是问题。
Turns out the UTF-8 characters are simply being raw url encoded . 事实证明,UTF-8字符仅是原始url编码 。 All I need to do to decode them on my PHP side is run them through rawurldecode() first then pass it on to my filters for further testing.
我需要在PHP端对其进行解码的所有操作是先通过rawurldecode()运行它们,然后将其传递给我的过滤器以进行进一步测试。
