我正在运行Coldfusion8并且有一个处理图像处理的 cfc。
从外部来源抓取图像、将它们放入临时存储、调整大小并保存到 S3 时，cfc 运行良好。我现在尝试通过此 cfc 运行手动上传的一组新图像，突然之间，我遇到了错误。
首先我抓取图像，将其存储在临时目录中，然后调用我的 img_handler：
<cffile result="temp" action="upload" accept="image/jpeg,image/jpg" filefield="Dateiname8" destination="#variables.tempDirectory#" nameconflict="overwrite" />
<cfset variables.testFilePath = variables.tempDirectory & temp.serverFile>
<!--- catch CMYK --->
<cfimage action="info" source="#variables.testFilePath#" structname="cmyk" />
<cfif cmyk.colormodel.colorspace EQ "Any of the family of CMYK color spaces">
<cfthrow type="FileNotFound" message="#tx_settings_icons_error_cymk#" />
</cfif>
<cfif structKeyExists( cookie, "resolution")>
<cfset variables.screenWidth = cookie.resolution>
<cfelse>
<cfset variables.screenWidth = "na">
</cfif>
<!--- call image handler --->
<cfinvoke component="services.form_img_handler" method="upload" returnVariable="variables.worked">
<cfinvokeargument name="cm" value="upload_background" />
<cfinvokeargument name="pt" value="#variables.tempDirectory#" />
<cfinvokeargument name="fl" value="#temp.serverFile#" />
<cfinvokeargument name="se" value="#form.app_basic_id#" />
<cfinvokeargument name="ar" value="background" />
<cfinvokeargument name="ck" value="#variables.screenWidth#" />
<cfinvokeargument name="gb" value="" />
<cfinvokeargument name="ax" value="int" />
<cfinvokeargument name="al" value="#variables.allow#" />
</cfinvoke>
这工作得很好。图像被创建并存储在temp临时文件夹中。我的问题是当我尝试像这样读取 image_handler 中的图像时：
<cfhttp timeout="500"
throwonerror="no"
url="#LOCAL.tempDirectory##LOCAL.imgFile#"
method="get"
useragent="Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12"
getasbinary="yes"
result="LOCAL.objGet">
这会产生以下错误：
catch - struct
Charset: [empty string]
ErrorDetail: I/O Exception: For input string: "\website\test\mem\secure\Innentitel.jpg"
Filecontent: Connection Failure
Header: [empty string]
Mimetype: Unable to determine MIME type of file.
Responseheader:
[struct]
Statuscode: Connection Failure. Status code unavailable.
Text: YES
我几乎不知道这里发生了什么。
问题
我的应用程序在 SSL 上运行，但是如果我可以在第一步中获取图像并将其存储在 temp 目录中，为什么我无法再次从我的 cfc 中将其拉入。问题可能是我使用的上传功能，access="remote"因为我也将此功能称为网络服务吗？如果是这样，我该怎么做才能让我的函数同时处理remote和regular请求？
感谢帮助！
编辑：
为了澄清，cfinvoke第一个代码块中的第一个代码块调用我的 cfc 来处理所有图像上传到 Amazon S3。在这个 cfc 中，我正在cfhttp拨打有问题的电话。这是我现在使用的方法cfimage，这迫使我在调用 cfc 之前进行所有验证。

所以我现在cfimage用来从临时文件夹中检索图像，这与cfhttp. 通话后我进行了图像验证例程cfhttp，现在我将其移至 cfc 调用之外。不确定这是否更好/更智能，但至少它现在正在工作。
