[英]How to parse a multipart form-data in webargs?
我需要使用webargs
解析帶有附件的多部分表單數據。 此刻我有下一個model:
RAW_ARGS = {
'file': fields.Field(
required=True,
validate=lambda file: file.mimetype == 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
location='files'),
'currency': fields.Int(required=True, validate=validate.OneOf([
ECurrency.EUR.value,
ECurrency.RUB.value,
ECurrency.USD.value
]), location='form')
}
class RawResource(Resource):
@token_required
@use_args(RAW_ARGS)
def post(self, args):
return '', 204
但是根據請求,我得到The request was well-formed but was unable to be followed due to semantic errors.
422
HTTP 狀態代碼錯誤。
以下是來自 Chrome 網絡的請求副本:

解析多部分表單數據的正確方法是什么?
PS我的服務器是Flask應用程序。
寫兩次@use_args,通過兩次。 我已經相應地編輯了您的代碼
RAW_ARGS = {
'file': fields.Field(
required=True,
validate=lambda file: file.mimetype == 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
location='files'),
'currency': fields.Int(required=True, validate=validate.OneOf([
ECurrency.EUR.value,
ECurrency.RUB.value,
ECurrency.USD.value
]), location='form')
}
class RawResource(Resource):
@token_required
@use_args(RAW_ARGS['file'])
@use_args(RAW_ARGS['currency'])
def post(self, args_file, args_currency):
return '', 204
