The error information is as follows:
System.NotSupportedException:“No data is available for encoding 1252. For information on defining a custom encoding, see the documentation for the Encoding.RegisterProvider method.”
Solution:
Add system.Through.nuget.Text.Encoding and system.Text.Encoding.References to codepages
Then add the following code to the code
System.Text.EncodingProvider ppp = System.Text.CodePagesEncodingProvider.Instance;
Encoding.RegisterProvider(ppp);OK solve the problem
HTTP error 500.19-Internal Server Error

Detailed error information:
Module: IIS Web Core
Notice: BeginRequest
error code: 0x800700b7
Configuration error: When the unique key attribute “name” is set to “ScriptHandlerFactory”, duplicate collection items of type “add” cannot be added
Because the child site inherits the web.config of the parent site
<location path="." allowOverride="true" inheritInChildApplications="false">
/* Wrap <system.web> with location in the web.config file
</system.web>
*/
// If it doesn't work, wrap all configurations with the <add> attribute in location
</location>
For example: system.web, system.webServer, ApplicationConfiguration and other configuration
locations with add attributes only need to be written once
Make the subsite not inherit the web.config of the parent site
Question 1:
HTTP Error 500.31 – Failed to load ASP. NET Core runtime
Common solutions to this issue:
The specified version of Microsoft. NetCore. App or Microsoft. AspNetCore. App was not found.
Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process’ stdout messages
Attach a debugger to the application process and inspect
reason
Cause of failure:
when the machine is published NETCORE version and server NETCORE version is inconsistent
Solution:
modify the published NETCORE version
Or synchronize the server’s environment download NET 5.0 (Linux, macOS, and Windows)
Question 2:
HTTP Error 500.30 – ASP. NET Core app failed to start
Common solutions to this issue:
The app failed to start
The app started but then stopped
The app started but threw an exception during startup
Troubleshooting steps:
Check the system event log for error messages
Enable logging the application process’ stdout messages
Attach a debugger to the application process and inspect
So I checked the event viewer & gt; Windows Log & gt; Appliction> The first time I checked the error log, I checked the following logs. I thought it was a CLR problem. After tossing around, I found that the problem was not solved.
Redis did not start and lost…
Then the most important thing is that all browsers are closed. It’s a little pit. It seems to occupy the port
Application specific permission settings do not grant the user NT service\SQLServerAgent in the address localhost (using LRPC) running in the application container unavailable Sid (unavailable) local activation permission for the COM server application with CLSID. This security permission can be modified using the component service management tool- Blue street lamp blog Garden
Question
supervisord -c /etc/supervisor/supervisord.conf
Error
Error: Another program is already listening on a port that one of our HTTP servers is configured to
Solution:
ps -ef | grep supervisord
Turn off the 8079 process
kill -s SIGTERM 8079
Solution results
supervisord -c /etc/supervisor/supervisord.conf
No error is the best case, indicating that the process is started successfully
StackExchange.Redis Error when loading large batch of hash data.
StackExchange.Redis.RedisTimeoutException: Timeout performing HGET Cache.IncomeShare.AccountData@Cache.IncomeShare.AccountData.InnerIncomeDistributionItem, inst: 1, mgr: ExecuteSelect, err: never, queue: 2, qu: 0, qs: 2, qc: 0, wr: 0, wq: 0, in: 0, ar: 0, clientName: xx, serverEndpoint: 192.0.x.x:6379, keyHashSlot: 10857, IOCP: (Busy=0,Free=1000,Min=6,Max=1000), WORKER: (Busy=0,Free=32767,Min=6,Max=32767) (Please take a look at this article for some common client-side issues that can cause。 timeouts: http://stackexchange.github.io/StackExchange.Redis/Timeouts)
According to the information to see IOCP and WORKER Busy are 0, will also report a timeout problem, is expected to be a StackExchange.Redis bug, the solution can be changed to use FreeRedis.
Error handling in map operation of ABP
When mapping an entity object into dto in ABP, the entity defines an object of type long. In dto, there is an object with the same name, but the type is guid,
// StudentEntity
public class StudentEntity
{
public Guid RelatedStudentId
{
get; set;
}
}
// StudentDto
public class StudentDto
{
public Guid StudentId
{
get; set;
}
public Long RelatedStudentId
{
get; set;
}
}
Take studententity and studentdto for example. Due to the change of business, when the back-end modifies the database and does not change the front-end code for the time being,
Directly map the relatedpatientid in entity to the studentID in dto , In this way, an error will occur when mapping, indicating that the type conversion error is wrong, and the data of the guid cannot be assigned to long,
CreateMap<StudentEntity, StudentDto>()
.ForMember(d => d.StudentId, map => map.MapFrom(o => o.RelatedStudentId))
At this time, the entity’s guid type relatedpatientid will be mapped to the long type relatedpatientid in dto,
This kind of data definition should be avoided in map operation.
