How to get business error message #106

Hi

Please see following scenario: I have an application service, in the business logic, need to do some business rule validation. If validation failed, then I throw an AbpException as following” throw new Abp.AbpException("Available balance is not enough.");

But when I invoked the service, I get following response:

{
   "success": false,
   "result": null,
   "error":    {
      "code": 0,
      "message": "An internal error occured during your request!",
      "details": null,
      "validationErrors": null
   },
   "unAuthorizedRequest": false
}

You can see the error message is a common message ‘An internal error occured during your request!’, but the message I want is ‘Available balance is not enough’. The common error message is fine for unexpected exception, but for the business error, I need to get specific business error message in front-end application. Do you have any suggestion?

BTW, there is spelling error: An internal error occured during your request! An internal error occurred during your request!

    I have addressed it by changing the code as following :

    throw new UserFriendlyException("Available balance is not enough.");
    

    then the response is:

    <Response xmlns="http://localhost/api/services/app/orderpublish/publishorder">
       <error>
          <code>0</code>
          <details null="true"/>
          <message>Available balance is not enough.</message>
          <validationErrors null="true"/>
       </error>
       <result null="true"/>
       <success>false</success>
       <unAuthorizedRequest>false</unAuthorizedRequest>
    </Response>
    

    Not sure if it is the best way, if not, could you please let me know the best practice?

    Hi,

    UserFriendlyException is built exactly for this reason. So, you've done it right.

    I fixed the spelling error: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/commit/36bf6687f442ac32ff22694742f9049c8dfe724b">https://github.com/aspnetboilerplate/as ... 9c8dfe724b</a>

    Thanks.
