Question

我目前正在评估ABP 3.9，并且无法创建租户。
执行此代码时失败：

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

这是我得到的例外：

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。不知道为什么仅对于租户创建失败。我正在扩展示例模板，该模板可在ASP.NET Boilerplate网站上免费获得。

非常感谢您的帮助。问候， Zainu

在TenantAppService类的Create方法下，注释掉了从输入DTO创建加密的连接字符串的代码。添加了一种从配置中读取连接字符串的方法，在我的情况下可以使用，因为我有一个针对所有租户的数据库。该数据库非常小，将仅存储有关租户的元数据，而大多数应用程序数据将存储在Azure存储中。

    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));

直到将代码部署到Azure中，我才意识到它最终会出现异常“ System.ApplicationException：找不到内容根文件夹”。

对我来说很幸运，这里https://github.com/aspnetboilerplate/aspnetboilerplate-templates/issues/43上有一个讨论，而解决方法是相同的

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