IIS 配置问题

Posted 2020-09-11

* 未显示页面 因为请求实体过大

问题描述：在 IIS 上部署了一个可以接收文件上传的 POST webAPI ,使用 Http 验证时没有任何问题，使用 SSL 后，如果传的图片过大，就会导致错误：“未显示页面 因为请求实体过大”

解决方案：在   %WinDir%\System32\Inetsrv  目录下执行命令行

      appcmd.exe set config -section:system.webserver/serverruntime/uploadreadaheadsize: 204800/commit:apphost  

      根据需要调整大小；

 

* Windows 服务器支持 TLS 1.2 及以上版本

问题描述：今天在开发微信小程序时，遇到了 “tls 仅支持 1.2 及以上版本”，才知道 Windows 服务器默认没有打开支持设置；

解决方案：在PowerShell 中执行以下命令，并重启服务器即可；
