图表处理程序配置中的临时图像目录无效

Question

我正在使用高图,只有当我在Intranet网络中的IIS服务器上运行我的网站时才会收到此错误.相反,它在开发服务器中工作正常(visual studio 2012)

图表处理程序配置[c:\ TempImageFiles]中的临时图像目录无效.请编辑web.config文件.CharImageHandler键,Dir值必须指向有效目录.当存储模式等于文件系统时,该目录是临时映像存储所必需的.

堆栈跟踪

[DirectoryNotFoundException: Invalid temp images directory in chart handler configuration [c:\TempImageFiles\]. Please edit the web.config file. The CharImageHandler key, Dir value must point to a valid directory. The directory is required for temporary image storage when storage mode equals file system.]

Answer 1

以前它就是这样的 web.config

<add key="ChartImageHandler" value="storage=file;timeout=20; dir=c:\TempImageFiles/;" />

我删除了目录位置

<add key="ChartImageHandler" value="storage=file;timeout=20;" />

问题解决了.

Answer 2

检查您的服务器上是否存在该文件夹，并向您的站点正在为该文件夹运行的应用程序池的用户授予读/写权限。

或者，您可以简单地将临时文件夹移动到站点根目录 Es 中：“~/temp”并配置 highchart 以使用该文件夹。

或者你可以改变你的 ChartImageHandler 从

<add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" />

到

<add key="ChartImageHandler" value="storage=file;timeout=20;" />

所以他会使用默认的windows temp目录
