Angular 无法识别的配置节system.webServer。(用于角型芯-角型)
我试图在Asp.Net core api文件中集成angular,但在访问/调用api(.core)时,显示了以下错误。已经通过了不同的链接,不知道确切的原因,这导致了错误Angular 无法识别的配置节system.webServer。(用于角型芯-角型),angular,asp.net-core,Angular,Asp.net Core,我试图在Asp.Net core api文件中集成angular,但在访问/调用api(.core)时,显示了以下错误。已经通过了不同的链接,不知道确切的原因,这导致了错误 // "error": { "innerExceptionMessage": "Failed to read the config section for authentication providers.", "mess

我正在显示上面的配置,因为错误显示在
我缺少的内容请与我分享相关想法/链接和代码。您的开发计算机上缺少IIS服务器的URL重写扩展,因此无法识别配置的重写规则部分
您有两种选择:
安装URL重写扩展
删除或注释掉web.config中的“重写规则”部分。也许您根本不需要开发机器上的URL重写功能
尝试了第二个选项,但仍然显示上述错误。您现在添加的第二个错误与第一个错误无关,因此注释掉“重写规则”部分就成功了。也许第二个错误应该在另一个问题中。明白了。。那里几乎没有字符空间。。现在这个工作很好。谢谢@Nenad
