设置IIS7文件上传的最大大小 maxAllowedContentLength,maxRequestLength
PS:IIS7.5只能上传2M的数据,超过2M,程序会出现错误。
解决方案:
applicationhost.config
打开 %windir%\system32\inetsrv\config\applicationhost.config
找到: 节点,
这个节点默认没有 元素,IIS 7和IIS 7.5上测试过 最大值只能是 <4GB,
为这个节点新增如下事例元素: ,上传的大小将改为2G注意:%windir%\system32\inetsrv\config\applicationhost.config
文件一定不要用其他机器的文件替换,否则IIS将无法启动
此文件记录了,当前IIS中所有Site , App pool的信息,还有一些与机器相关的配置。
<system.web>
<httpRuntime executionTimeout="36000" maxRequestLength="2097151"/>
system.web>
注意:这个maxRequestLength最大值只能是2097151K,设置大于这个值将会出现如下错误:
