如图所示，django无法渲染html显示成下载文件了

一步一步的从render ==》HttpResponse ==》HttpResponseBase 找到

即django文件夹下的http文件夹内的response.py文件

classHttpResponseBase:"""An HTTP response base class with dictionary-accessed headers.

This class doesn't handle content. It should not be used directly.

Use the HttpResponse and StreamingHttpResponse subclasses instead."""status_code= 200

def __init__(self, content_type=None, status=None, reason=None, charset=None):#_headers is a mapping of the lower-case name to the original case of

#the header (required for working with legacy systems) and the header

#value. Both the name of the header and its value are ASCII strings.

self._headers ={}

self._closable_objects=[]#This parameter is set by the handler. It's necessary to preserve the

#historical behavior of request_finished.

self._handler_class =None

self.cookies=SimpleCookie()

self.closed=Falseif status is notNone:try:

self.status_code=int(status)except(ValueError, TypeError):raise TypeError('HTTP status code must be an integer.')if not 100 <= self.status_code <= 599:raise ValueError('HTTP status code must be an integer from 100 to 599.')

self._reason_phrase=reason

self._charset=charsetif content_type isNone:

content_type= '%s; charset=%s' %(settings.DEFAULT_CONTENT_TYPE,

self.charset)

self['Content-Type'] = content_type

需要在django项目下的settings.py文件添加下面内容

DEFAULT_CONTENT_TYPE = 'text/html'

为了保证Content-Type的值返回正常的值

将response.py的

self['Content-Type'] = content_type

更改成

self['Content-Type'] = content_type if type(content_type) == type('') else 'text/html; charset=utf-8'

然后重新dajngo服务

成功渲染html文件
