Question

我做了什么：

我在Azure中添加了资源组。
使用以前的资源组添加了Web服务。
添加了以前资源组的SQL Server数据库。
从此数据库中检索生成的连接字符串，并在此处提供用户名和密码。
将此连接字符串添加到Web Service中的App Settings。
通过Visual Studio发布的应用程序。

问题：当我尝试在azure中测试这个托管应用程序时，我收到此错误，但在我的本地版本的应用程序和确切的连接字符串一切正常...

Answer 1

问题是Microsoft生成的连接字符串中的两个键。您必须设置为“Persist Security Info”和“TrustServerCertificate”键值：“True”。

Answer 2

对于我的 net core 3.1 ，我尝试通过Configuration.GetConnectionString进行连接以提供连接字符串，该字符串存储在 appsettings.json 中， password具有unicode值，并且json文件以UTF-8以外的其他格式保存。因此，要解决此问题，我必须将json文件保存为UTF-8编码，并且可以正常工作。

Answer 3

出现我的问题，因为我试图将 SQL DB 连接字符串从数据库“连接字符串” 部分复制/粘贴到Web API ” “应用程序设置->连接字符串” 部分中未设置连接字符串User ID和Password的值，即：
