1. 在這裡下載 https://certbot.eff.org/lets-encrypt/windows-other.html

2. 安裝下載的程式

3. 用 cmd (管理員模式, 執行以下指令)
certbot certonly --manual --agree-tos -d "*.bike.idv.tw" -d "bike.idv.tw" --email bikehsu@gmail.com --preferred-challenges dns --manual-public-ip-logging-ok --server https://acme-v02.api.letsencrypt.org/directory

4. 會需要在 DNS Server 上建立一個 TXT 記錄.

5. 下載的格式是 pem, 可以在這裡轉成 IIS 用的 pfx 格式. https://decoder.link/converter, 轉檔時, "不"要用 fullchain

6. 用這個指令可以顯示所有 certbot 申請的憑証 "certbot certificates"

7. "certbot renew" 可以 renew  certificate, 需要測試.

1. 參考這裡設定第一個網站:
https://blog.johnwu.cc/article/centos-asp-net-core-neginx.html
注意, 文章中有一個錯誤:
/etc/nginx/conf.d/my-website.conf 的第 27 行, 應該是 include /etc/nginx/conf.d/default_proxy_settings;

2.  因為要避開 5000 port, 所以修改第二個網站的 appsettings.json, 讓第二個網站開在 5002 port, 如下.

{

"Logging": {

    "LogLevel": {

     "Default": "Information",

     "Microsoft": "Warning",

     "Microsoft.Hosting.Lifetime": "Information"

    }

},

"Kestrel": {

        "EndPoints": {

                "Http": {

                        "Url": "http://localhost:5002"

                }

        }

},

"AllowedHosts": "*"

}

3. 新增 /etc/nginx/conf.d/my-website2.conf, 要注意
    A. portal2
    B. server localhost:5002
    C. server_name coretest2.bike.idv.tw
    當然 SSL 憑証的檔名也要記得改.

upstream portal2 {

    # localhost:5000 改成 ASP.NET Core 所監聽的 Port

    server localhost:5002;

}



server {

    # 只要是透過這些 Domain 連 HTTP 80 Port，都會轉送封包到 ASP.NET Core

    listen 80;

    # 可透過空白區分，綁定多個 Domain

    server_name coretest2.bike.idv.tw;

    location / {

        proxy_pass http://portal2/;

        include /etc/nginx/conf.d/default_proxy_settings;

    }

}



# 用 HTTPS 必須要有 SSL 憑證，如果沒有要綁定 SSL 可以把下面整段移除

server {

    # 只要是透過這些 Domain 連 HTTPS 443 Port，都會轉送封包到 ASP.NET Core

    listen 443 ssl;

    server_name coretest2.bike.idv.tw;

    ssl_certificate /etc/nginx/ssl/coretest2.bike.idv.tw.crt;

    ssl_certificate_key /etc/nginx/ssl/coretest2.bike.idv.tw.key;



    location / {

        proxy_pass http://portal2/;

        include /etc/nginx/conf.d/default_proxy_settings;

    }

}

改完後就可以用了.

nginx -t



# 若沒有錯誤，即可套用

nginx -s reload

海底撈刀削拌麵 (素, 胡麻醬) 推

宮保雞丁刀削炒麵  沒有不辣的選項

蔥爆牛肉刀削炒麵 
 
醬汁是甜的那種
優點：
牛肉不是乾乾的 是有汁的那種 也很軟 好吃
缺點：
以外送來說 有點乾 麵會黏在一起
很多胡椒粉，怕辣的人建議略過此餐點

for VS2017: 在 sln 檔的目錄下, 找 .vs\config\applicationhost.config

例如: 
D:\ASP.NET Project\S3_WEB4_NET\.vs\config\applicationhost.config


For VS2019: $(solutionDir)\.vs\{slnName}\config\applicationhost.config
例如:
D:\ASP.NET Project\S3_WEB4_NET\.vs\S3\config\applicationhost.config

VS 2013 發生的錯誤

https://stackoverflow.com/questions/23893497/no-editoroptiondefinition-export-found-error

1. Close Visual Studio
2. Open the folder: %LocalAppData%\Microsoft\VisualStudio\12.0\ (in C:\users\'%userName%'\AppData\Local\Microsoft\VisualStudio\12.0\)
3. Rename the ComponentModelCache folder
4. Restart Visual Studio.

 

IIS 7.0 之後 
用 HttpContext.Current.Request.UserHostAddress 抓的IP會是 
類似 fe80::b148:cddc:81cd:fd10%2 
這樣的IPv6 位址
如果要抓 IPv4 要特別改寫

參考
https://dotblogs.com.tw/hunterpo/2011/03/21/21991


HttpContext.Current.Request.UserHostAddress


暫時的替代方法
public static string GetClientIPv4() { string ipv4 = String.Empty; foreach (IPAddress ip in Dns.GetHostAddresses(GetClientIP())) { if (ip.AddressFamily.ToString() == "InterNetwork") { ipv4 = ip.ToString(); break; } } if (ipv4 != String.Empty) { return ipv4; } // 原作使用 Dns.GetHostName 方法取回的是 Server 端資訊，非 Client 端。 // 改寫為利用 Dns.GetHostEntry 方法，由獲取的 IPv6 位址反查 DNS 紀錄， // 再逐一判斷何者屬 IPv4 協定，即可轉為 IPv4 位址。 foreach (IPAddress ip in Dns.GetHostEntry(GetClientIP()).AddressList) //foreach (IPAddress ip in Dns.GetHostAddresses(Dns.GetHostName())) { if (ip.AddressFamily.ToString() == "InterNetwork") { ipv4 = ip.ToString(); break; } } return ipv4; } /// <summary> /// 取得客戶端主機位址 /// </summary> public static string GetClientIP() { if (null == HttpContext.Current.Request.ServerVariables["HTTP_VIA"]) { return HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]; } else { return HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; } }

使用範例如下:

    void getList()

    {

        var Q = TN.Admin.TCatOrderDeliveryRecord.Select().OrderBy("DeliveryCompletion_Date, Id Desc");



        if (U2.WU.IsNonEmptyFromQueryStringOrForm("OD00"))

        {

            Q.And("OD00 = ", U2.WU.GetValue("OD00"));

        }



        if (U2.WU.V.StartDate_IsOK)

        {

            Q.And("DeliveryCompletion_Date >= ", U2.WU.V.StartDate);

        }



        if (U2.WU.V.EndDate_IsOK)

        {

            Q.And("DeliveryCompletion_Date < ", U2.WU.V.EndDate);

        }



        U2.JSON.WriteSuccessData(Q.GetPageDT2(U2.WU.V.CurrentPage, U2.WU.V.PageSize));

    }
