todo: drf render 駝峯<->下劃線

背景

• py後端. 下劃線

• 其他方. 駝峯

• py 給 前端響應 HumJSONRenderer

• py 接收 前端請求 SnakeJSONParser

drf parser .

• JSONParser
• HumJSONParser(駝峯格式)
• UnderLineJSONParser(下滑格式)
• SnakeJSONParser(解析駝峯Json到python的下劃線json)

parser.py

class SnakeJSONParser(JSONParser):
    def parse(self, stream, media_type=None, parser_context=None):
        parser_context = parser_context or {}
        # utf-8
        encoding = parser_context.get('encoding', settings.DEFAULT_CHARSET)
        try:
            data = stream.read().decode(encoding)
            data_str = json_hump2underline(data)
            return json.loads(data_str)
        except ValueError as exc:
            raise ParseError('JSON parse error - %s' % six.text_type(exc))

drf render 改寫.

• JSONRenderer
• HumJSONRenderer(駝峯格式)
• UnderLineJSONRenderer(下滑格式)
