HTML表单提交给出了400个错误的请求 [英] HTML form submit giving 400 bad request
问题描述
我正在使用POST方法向REST(eXist db)Web服务提交HTML表单.正常提交是给 400错误的请求
I'm submitting a HTML form to REST(eXist db) web service using POST method.A normal submission is giving 400 bad request
这是我的HTML代码
<html>
<script type="text/javascript">
/* function createXMLHttpRequest()
{
if( typeof XMLHttpRequest == "undefined" )
XMLHttpRequest = function()
{
try
{
return new ActiveXObject("Msxml2.XMLHTTP.6.0")
}
catch(e) {}
try
{
return new ActiveXObject("Msxml2.XMLHTTP.3.0")
}
catch(e) {}
try
{
return new ActiveXObject("Msxml2.XMLHTTP")
}
catch(e) {}
try
{
return new ActiveXObject("Microsoft.XMLHTTP")
}
catch(e) {}
throw new Error( "This browser does not support XMLHttpRequest." )
};
return new XMLHttpRequest();
}
var AJAX = createXMLHttpRequest();*/
function submitForm()
{
//AJAX.open("POST",'http://localhost:8899/exist/rest/db/xql/sample.xq');
// AJAX.send(document.form.xmlData.value);
document.form.submit();
};
</script>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
</head>
<body>
<form name='form' action="http://localhost:8899/exist/rest/db/xql/sample.xq" enctype="text/plain" method="post">
<input type="text" name="xmlData"/>
<input type="button" value="Submit" onclick="submitForm()";>
</form>
</body>
</html>
注释的代码是使用AJAX发送POST请求. 我捕获了http标头请求和表单提交和AJAX提交的响应 这些是请求标头:
The commented code is to send POST request using AJAX. I captured the http header request and response for form submit and AJAX submit These are the request headers:
HTML表单提交标头:
HTML form submit header:

AJAX请求标头:

我没有弄清楚我的代码有什么问题. 我为此工作了两天，但我找不到任何解决方案. 请对此进行调查并提供解决方案.
Im not getting what's wrong in my code . Im working on this for 2 days but i din't find any solution. Please look into this and provide a solution.
先谢谢了.
推荐答案
但是您不使用Ajax POST发送任何参数吗?
But you aren't sending any parameters with the Ajax POST?
Ajax代码应如下所示:
The Ajax code should look something like this:
var xmlData=encodeURIComponent(document.getElementById("xmlData").value);
var parameters="xmlData="+xmlData;
AJAX.open("POST", "'http://localhost:8899/exist/rest/db/xql/sample.xq", true)
AJAX.setRequestHeader("Content-type", "application/x-www-form-urlencoded")
AJAX.send(parameters)
