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（visual studio 2012）

中工作正常

图表处理程序配置中的临时图像目录无效 [C：\ TempImageFiles]。请编辑web.config文件。该 CharImageHandler键，Dir值必须指向有效目录。该存储模式时临时映像存储需要目录等于文件系统。

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

以前在web.config

中就是这样的

<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

检查服务器上是否存在该文件夹，并为您的网站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该临时文件夹移动到站点根目录Es：＆＃34;〜/ temp＆＃34;并配置highchart以使用该文件夹。

或者您可以从

更改ChartImageHandler

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

要

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

所以他将使用默认的Windows临时目录
