ABP 租户创建失败

Question

我目前正在评估 ABP 3.9，但无法创建租户。
执行此代码时失败：

CheckErrors(await _roleManager.CreateStaticRoles(tenant.Id));

这是我得到的异常：

Mvc.ExceptionHandling.AbpExceptionFilter - Format of the initialization string does not conform to specification starting at index 0.
System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.
   at System.Data.Common.DbConnectionOptions.GetKeyValuePair(String connectionString, Int32 currentPosition, StringBuilder buffer, Boolean useOdbcRules, String& keyname, String& keyvalue)
   at System.Data.Common.DbConnectionOptions.ParseInternal(Dictionary`2 parsetable, String connectionString, Boolean buildChain, Dictionary`2 synonyms, Boolean firstKey)
   at System.Data.Common.DbConnectionOptions..ctor(String connectionString, Dictionary`2 synonyms)
   at System.Data.SqlClient.SqlConnectionString..ctor(String connectionString)
   at System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions(String connectionString, DbConnectionOptions previous)
   at System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup(DbConnectionPoolKey key, DbConnectionPoolGroupOptions poolOptions, DbConnectionOptions& userConnectionOptions)
   at System.Data.SqlClient.SqlConnection.ConnectionString_Set(DbConnectionPoolKey key)
   at System.Data.SqlClient.SqlConnection.set_ConnectionString(String value)
   at Microsoft.EntityFrameworkCore.SqlServer.Storage.Internal.SqlServerConnection.CreateDbConnection()

相同的 Entity Framework 连接可与我添加的其他 ApplicationService 类一起使用。不知道为什么仅针对租户创建失败。我正在扩展示例模板，可在 ASP.NET 样板网站上免费获得。

非常感谢您的帮助。问候，再努

Answer 1

在 TenantAppService class 中的 Create 方法下注释掉了从输入 DTO 创建加密连接字符串的代码。添加了一种从配置中读取连接字符串的方法，这在我的情况下有效，因为我有一个数据库用于所有 tenants.This 数据库将非常小，并且它将仅存储有关租户的元数据，而大部分应用程序数据将在 Azure 中存储。

    public override async Task<TenantDto> Create(CreateTenantDto input)
    {
        CheckCreatePermission();

        // Create tenant
        var tenant = ObjectMapper.Map<Tenant>(input);
        //this code is commented since we have single database for all tenants
        //tenant.ConnectionString = input.ConnectionString.IsNullOrEmpty()
        //    ? null
        //    : SimpleStringCipher.Instance.Encrypt(input.ConnectionString);

        //This would read connection string from configuration and pass it to 
       //connectionstring property of AbpTenant
        var configuration = 
       AppConfigurations.Get(WebContentDirectoryFinder.CalculateContentRootFolder());
        tenant.ConnectionString = SimpleStringCipher.Instance.Encrypt(configuration.GetConnectionString(OneCloudConsts.ConnectionStringName));

直到代码部署到 Azure 中我才意识到它最终会出现异常 "System.ApplicationException: Could not find content root folder"。

我很幸运，这里有关于相同问题的讨论 https://github.com/aspnetboilerplate/aspnetboilerplate-templates/issues/43 并且修复是相同的

var startupPath = System.IO.Directory.GetCurrentDirectory(); var 配置 = AppConfigurations.Get(startupPath); tenant.ConnectionString = SimpleStringCipher.Instance.Encrypt(configuration.GetConnectionString(OneCloudConsts.ConnectionStringName));
