django rest_framework中将json输出字符强制为utf-8编码-白红宇

最近在和日本外包合作开发JIRA对接发布系统的版本单时，

遇到这个问题。

就是我们这边的输出浏览器显示为中文，而到了JIRA端就出现乱码。

查了文档，原来django rest_framework的默认json是没指定编码的，

需要随接收方的环境编码来显示。

于是，因为项目进度，我们对了强制编码操作。

查看rest framework的源代码：

class JSONRenderer(BaseRenderer):    """    Renderer which serializes to JSON.    """    media_type = 'application/json'    format = 'json'    encoder_class = encoders.JSONEncoder    ensure_ascii = not api_settings.UNICODE_JSON    compact = api_settings.COMPACT_JSON    # We don't set a charset because JSON is a binary encoding,    # that can be encoded as utf-8, utf-16 or utf-32.    # See: http://www.ietf.org/rfc/rfc4627.txt    # Also: http://lucumr.pocoo.org/2013/7/19/application-mimetypes-and-encodings/    charset = None

　　于是，我们重写了一个继承自JSONRenderer的Utf8JSONRenderer。然后，指定一个renderer_classes属性值即可。

from rest_framework.renderers import JSONRendererclass Utf8JSONRenderer(JSONRenderer):    charset = 'utf-8'

class DeployPoolViewSet(viewsets.ModelViewSet):    """    This viewset automatically provides `list`, `create`, `retrieve`,    `update` and `destroy` actions.    Additionally we also provide an extra `highlight` action.    """    serializer_class = DeployPoolSerializer    authentication_classes = (TokenAuthentication,)    renderer_classes = (Utf8JSONRenderer,)
