Google api ColdFusion Google OAuth获取访问令牌连接失败

下面的例子来自。在我尝试获取访问令牌之前，一切正常。我的getAccessToken（）函数出现“连接失败”错误。不知道我做错了什么

<cfset authurl = "https://accounts.google.com/o/oauth2/v2/auth?" & 
"client_id=#urlEncodedFormat(application.clientid)#" & 
"&redirect_uri=#urlEncodedFormat(application.callback)#" & 
"&scope=https://www.googleapis.com/auth/userinfo.profile&response_type=code"> 
<cfoutput> 
authurl=#authurl#
<p><a href="#authurl#">Login</a></p> 
</cfoutput>

<cffunction name="getAccessToken"> 
<cfargument name="code" required="false" default="" type="string">
<cfset var postBody = "code=" & UrlEncodedFormat(arguments.code) & "&"> 
<cfset postBody = postBody & "client_id=" & UrlEncodedFormat(this.clientid) & "&"> 
<cfset postBody = postBody & "client_secret=" & UrlEncodedFormat(this.clientsecret) & "&"> 
<cfset postBody = postBody & "redirect_uri=" & UrlEncodedFormat(this.callback) & "&"> 
<cfset postBody = postBody & "grant_type=authorization_code">

<cfhttp method="post" url="https://www.googleapis.com/oauth2/v4/token"> 
<cfhttpparam type="header" name="Content-Type"  value="application/x-www-form-urlencoded"> 
<cfhttpparam type="body" value="#postBody#">     
</cfhttp>   
<cfreturn deserializeJSON(cfhttp.filecontent.tostring())>

authurl=#authurl#

更换线路

<cfset postBody = postBody & "client_id=" & UrlEncodedFormat(this.clientid) & "&"> 
<cfset postBody = postBody & "client_secret=" & UrlEncodedFormat(this.clientsecret) & "&"> 
<cfset postBody = postBody & "redirect_uri=" & UrlEncodedFormat(this.callback) & "&">

您可以访问

https://www.googleapis.com

来自ColdFusion服务器？这很可能与使用cfhttp通过SSL（https）进行连接有关。看看这个答案，可以得到详细的解释，祝你好运！谢谢你们两位！你提供的链接上的说明解决了这个问题！

<cfset postBody = postBody & "client_id=" & UrlEncodedFormat(application.clientid) & "&"> 
<cfset postBody = postBody & "client_secret=" & UrlEncodedFormat(application.clientsecret) & "&"> 
<cfset postBody = postBody & "redirect_uri=" & UrlEncodedFormat(application.callback) & "&">
