Question

以下是将enctype属性添加到表单标记并观察传递的参数丢失的简单示例。

## test.rest.cfm
<!doctype html>
<html>
<head>
<title>Test Form</title>
</head>
<body>
<div>
<p>Will Post From Here</p>
<form method="post" action="http://devserver/rest/ost/testform/" name="frmName">
<table>
<tr>
<td>fname</td>
<td><input type="text" name="fname" id="fname" value="Fredley"></td>
</tr>
<tr>
<td>lname</td>
<td><input type="text" name="lname" value="Solongo"></td>
</tr>
<tr>
<td>&nbsp;</td>
<td><input type="submit" value="Post"></td>
</tr>
</table>
</form>
</div>
</body>
</html>

## testFormHandler.cfc
<cfcomponent restpath="testform" rest="true" produces="application/JSON">

<cffunction description="POST method to test form"
name         = "postMethod"
access       = "remote"
output       = "false"
returntype   = "string"
returnformat = "json"
httpmethod   = "post" >

<cfargument required="1" type="any" restArgSource="Form" name="fname">
<cfargument required="1" type="any" restArgSource="Form" name="lname">

<cfset var arrayReturn = {}>
<cfset arrayReturn["fname"] = arguments.fname>
<cfset arrayReturn["lname"] = arguments.lname>

<cfreturn "{""PayLoad"":" & SerializeJSON(arrayReturn) & ",""Type"":""Success"",""Message"":""SUCCESS"",""Code"":""SUCCESS""}">

</cffunction>

</cfcomponent>

## change form tag of test.rest.cfm to gets param fname failure
<form method="post" action="http://dev1.ostit.com/rest/ost/testform/" name="frmName" enctype="multipart/form-data">

## results with no enctype
{"PayLoad":{"fname":"Fredley","lname":"Solongo"},"Type":"Success","Message":"SUCCESS","Code":"SUCCESS"}

## results with enctype added
{"Message":"The FNAME parameter to the postMethod function is required but was not passed in."}

当包含enctype时，restArgSource是否应该不同？显然，http标头会改变，但是使用带有restargname的标头也不起作用......

getting started guide说：

“另外，在将数据作为表单字段发送时，必须将content-type标头设置为application / x-www-form-urlencoded。”

所以你可能会因为运气不好而害怕。您可能能够获得底层http请求的句柄并访问请求体，但这是相当多的工作。使用多部分表单的原因是什么？我猜文件上传，但我有兴趣知道是否有另一个用例。

使用常规CFFile处理看起来像file upload itself will work in REST。如果你可以处理在URL上放置其他参数，你可能会得到一些可行的东西。

restArgSource值应该用于Coldfusion 10 Rest服务和enctype？
