部署之前先檢查下面2個先決條件是否滿足
1、安裝了 IIS 模塊
win7
在 控制面板→程序和功能→打開或關閉Windows功能→勾選Internet 信息服務（Internet Information Services）安裝IIS功能
win server
控制面板→程序和功能→打開或關閉Windows功能→添加角色和功能→下一步選擇web服務器（IIS）→勾選安裝即可
2、安裝了 AspNetCoreModule 托管模塊
檢查 Internet 信息服務(IIS)管理器 服務器的模塊里面有沒有 托管模塊
如果沒有點擊下面的鏈接下載安裝
這個是netcore2.1版本
https://pan.baidu.com/s/1AUWntFGHlFYqaWa7aNi9YA
安裝完之后最好重啟一下系統
3、前兩個條件都滿足之后，就可以部署IIS站點了，跟平時部署站點的唯一區別就是 應用程序池，選擇【無托管代碼】，其他基本和 .net 一模一樣
解決方案的發布就不再描述了
按照上面兩步操作之后依然不能正常訪問的話
可以配置下 web.config 里的日志輸出目錄，跟蹤日志查找原因
這里有一個坑需要注意一下，就是日志輸出的目錄默認是 logs 文件夾下面的，但是它又不會自動創建這個logs目錄，簡直就是sb操作
所以修改下目錄為程序當前目錄（.\）即可，然后將目錄開關（stdoutLogEnabled）設置成 true
參考下面黃色標注的部分
<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModule" resourceType="Unspecified" /> </handlers> <aspNetCore processPath="dotnet" arguments=".\GeduDistributionApi.dll" stdoutLogEnabled="true" stdoutLogFile=".\" /> </system.webServer> </location> </configuration> <!--ProjectGuid: 92985990-0187-402f-a970-e6c36b29150d-->
這個時候如果網站訪問成功就會看到目錄下有 .log 文件
查看內容，說明網站已經成功啟動，並沒有報錯信息

下面是一個報錯異常的日志信息，根據日志錯誤，可以很容易定位到相應的錯誤，從而修正即可

上面的報錯信息說明，mvc api接口里的方法必須指明請求方式，get或者post等，所以在方法前面加上 [HttpGet] 即可。
