IIS 配置问题
* 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;
