Structure tag field annotation

• header
  • Can use commonly used types(ptr, slice), in slice type use ',' split
  • Value is an alias for a field, 'omitempty' is nullable
• cookie
  • Can use commonly used types(ptr, slice) or *http.Cookie, in slice type use ',' split
  • Value is an alias for a field, 'omitempty' is nullable
• query
  • Can use commonly used types(ptr, slice)
  • Value is an alias for a field, 'omitempty' is nullable
• path
  • Can use commonly used types(ptr, slice), in slice type use ',' split
  • Value is an alias for a field, 'omitempty' is nullable
• form
  • Can use commonly used types(ptr, slice), in slice type use ',' split
  • default media type 'application/x-www-form-urlencoded', if file exists 'multipart/form-data'
  • Value is an alias for a field, 'omitempty' is nullable
• file
  • Can use commonly used *multipart.FileHeader or []*multipart.FileHeader
  • default media type 'multipart/form-data'
  • Value is an alias for a field, 'omitempty' is nullable
• body
  • The values are xml and json, Multiple uses ',' segmentation
  • Value of json is media type 'application/json', xml is media type 'application/xml'
  • Body of tag use value, 'omitempty' is nullable

Structure tag annotation

• regexp
  • Regular expression of value
  • Equivalent to OpenAPI pattern
• enum
  • Enumeration of values
  • Limit integer number boolean string type
  • Comma division (,)
• default
  • Default value
• example
  • Example value
• desc
  • Field description
  • Equivalent to OpenAPI description
• lt
  • Less than value
  • Limit integer number type
  • Equivalent to OpenAPI exclusiveMaximum
• lte
  • Less than or equal to value
  • Limit integer number type
  • Equivalent to OpenAPI maximum
• gt
  • Greater than value
  • Limit integer number type
  • Equivalent to OpenAPI exclusiveMinimum
• gte
  • Greater than or equal to value
  • Limit integer number type
  • Equivalent to OpenAPI minimum
• multiple
  • Multipliers of values
  • Limit integer number type
• max
  • The maximum length of the value
  • Limit string array object type
• min
  • The minimum length of the value
  • Limit string array object type
• unique
  • The value of the array is unique
  • Limit array type

Response annotation

• if response is an implementation of the goapi.Response interface, you can set the http Code and header
• else do not set the header, and set the HTTP code to 200

Error corresponding comment

goapi.HTTPException(404, "error message")

• Specific return information can be configured using the 'HTTPExceptionHandler' method
• The first parameter is the HTTP status code, the second is the error message, and the third is the header setting returned
