为什么 Firefox 和 Chrome 在 POST 时将 LF 字符替换为 CR+LF?
我写了以下内容作为测试:
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js"></script>
<script type="text/javascript">
function lftest()
{
var linefeed = "before";
linefeed += String.fromCharCode(10); //linefeed
linefeed += "after";
$("#field").val(linefeed);
$("#formthing").submit();
}
</script>
</head>
<body>
<form id="formthing" method="post" action="http://someurl.com/resource">
<input type="hidden" id="field" value="" name="line" />
<a href="#" onclick="lftest()">send</a>
</form>
</body>
</html>
开发人员工具网络选项卡显示 POST 数据:
before%0D%0Aafter
最佳答案
原来这与 x-www-form-urlencoded 编码类型有关。根据the spec :
Non-alphanumeric characters are replaced by '%HH', a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., '%0D%0A').
