An error occurred while starting the application.web

1.修改web.config文件,stdoutLogEnabled改成true,以下:ide
<aspNetCore processPath="dotnet" arguments=".\Dialysis.WebApi.dll" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />
補充一點,這個文件是在發佈以後的文件裏,若是沒有單獨配置發佈文件。
就在\bin\Debug\netcoreapp1.1 裏面,在根目錄下有web.config文件。
注: 不在源文件的根目錄下面。
另外,需要手動建 這個 logs 文件夾,由於iis不會給你自動建立。
我出這個問題的緣由也是由於項目在startup的時候沒有讀到 nlog.config這個文件致使的錯誤。
在開發環境中,把這個文件的屬性配置成「複製到輸出目錄:始終複製」 和 「生成操做:內容」 就能夠了。網站
2.再次打開網站,仍是報上述錯誤,別急,查看發佈根目錄發現多了一個Logs文件夾,打開裏面的stdout_xxx.log文件ui

發現缺乏文件,把文件複製到發佈根目錄下就解決了code
