如何解决Coldfusion - 使用 Oauth2.cfc 获取“元素 STATUS_CODE 在作为表达式的一部分引用的 CFML 结构中未定义”
我是 oauth2 的新手，正在尝试按照此处的说明进行操作：https://github.com/coldfumonkeh/oauth2
在我的 bspace-callback.cfm 页面上请求访问令牌时出现以下错误：
Element STATUS_CODE is undefined in a CFML structure referenced as part of an expression.
The error occurred in C:/...oauth2.cfc: line 80
78 : }
79 : var result = httpService.send().getPrefix();
80 : if( '200' == result.ResponseHeader[ 'Status_Code' ] ) {
81 : stuResponse.success = true;
82 : stuResponse.content = result.FileContent;
这是我的页面：
bspace.cfm
<cfset myCfcObject = createObject("component","brightspace")>
<cfset oOauth2 = myCfcObject.init(
client_id = 'xxx',client_secret = 'xxx',redirect_uri = 'https://.../bspace-callback.cfm')>
<cfdump var="#myCfcObject#" label="myCfcObject's information."><BR>
<cfset strURL = oOauth2.buildredirectToAuthURL('enrollment:orgunit:create group:resource:permissions')>
<cfoutput>
<p>
<a href="#strURL#">LOGIN!</a>
</p>

我不确定如何解决，因为当我用谷歌搜索时似乎没有其他人遇到这个问题，所以我知道我一定做错了什么。
非常感谢您的帮助。
