When the ABP framework clock uses dapper, httppost calls the interface to report an error. Solution

1. The query method is tested separately successfully, and the httpget interface is called successfully. However, if it is called by the httpput or httppost interface, an error [err] beginexecutereader requires the command to have a transaction when the connection assigned to the command is in a pending local transaction   The Transaction property of the command has not been initialized.

Temporary processing method: using (idbconnection = dbconnection){



Change to

DbConnection.QueryAsync< T>



2. If the above method is still unsuccessful, add the [unitofwork (false, isolationlevel. Readcommitted)] attribute to the httppost interface of the controller layer.
