Django Python 获取请求头信息Content-Range的方法

request请求头信息的键会加上HTTP_转换成大写存到request.META中

因此你只需要

content_range = request.META['HTTP_CONTENT_RANGE']

这样就可以获取到Content-Range的信息。

django官网的解释：

A standard Python dictionary containing all available HTTP headers. Available headers depend on the client and server, but here are some examples:

CONTENT_LENGTH ?C The length of the request body (as a string).
CONTENT_TYPE ?C The MIME type of the request body.
HTTP_ACCEPT ?C Acceptable content types for the response.
HTTP_ACCEPT_ENCODING ?C Acceptable encodings for the response.
HTTP_ACCEPT_LANGUAGE ?C Acceptable languages for the response.
HTTP_HOST ?C The HTTP Host header sent by the client.
HTTP_REFERER ?C The referring page, if any.
HTTP_USER_AGENT ?C The client's user-agent string.
QUERY_STRING ?C The query string, as a single (unparsed) string.
REMOTE_ADDR ?C The IP address of the client.
REMOTE_HOST ?C The hostname of the client.
REMOTE_USER ?C The user authenticated by the Web server, if any.
REQUEST_METHOD ?C A string such as "GET" or "POST".
SERVER_NAME ?C The hostname of the server.
SERVER_PORT ?C The port of the server (as a string).
With the exception of CONTENT_LENGTH and CONTENT_TYPE, as given above, any HTTP headers in the request are converted to META keys by converting all characters to uppercase, replacing any hyphens with underscores and adding an HTTP_ prefix to the name. So, for example, a header called X-Bender would be mapped to the META key HTTP_X_BENDER.

很多同学在找Content-Range的时候发现文档中没有这个，所以以为不支持这个，一直再找。百度 Google什么的

但是其实这个文档只是列出的其中一部分，而且他们没细心的读A standard Python dictionary containing all available HTTP headers，这一句，同时上面的也只是一部分例子，因此在看文档的时候，希望同学们能细心一点！
