Requirements: If there is an enum type in the parameter, the interface will return a "400 Bad Request" error, because Refit converts the enum in the object to a string by default, and the interface cannot convert the string to an enum error, as follows:

{
"type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
"title": "One or more validation errors occurred.",
"status": 400,
"traceId": "00-3aef79a91ce9c411883953c9aaccb48a-68917b547ba8a2e5-00",
"errors": {
      "req": [
         "The req field is required."
      ],
      "$.languagePermissions": [
         "The JSON value could not be converted to LanguagePermissionsEnum. Path: $.languagePermissions | LineNumber: 0 | BytePositionInLine: 145."
      ]
}
}

The official explanation is that the reason for converting enums to strings by default is becauseIncrease readability and facilitate reading of parameter content information。 Reference:The hyperlink login is visible.

The default behavior is to serialize the enum to a string, which you can change by providing the serializer with your own settings:The hyperlink login is visible.

So, we pass in the custom Refit settings and don't use the default settings, deleteJsonStringEnumConverterThe converter is fine, the code is as follows:

Login is visible.

Solution:The hyperlink login is visible.
(End)
