request請求頭信息的鍵會加上HTTP_轉換成大寫存到request.META中
因此你只需要
content_range = request.META['HTTP_CONTENT_RANGE']
這樣就可以獲取到Content-Range的信息。
django官網的解釋：
A standard Python dictionary containing all available HTTP headers. Available headers depend on the client and server, but here are some examples:
CONTENT_LENGTH– The length of the request body (as a string).CONTENT_TYPE– The MIME type of the request body.HTTP_ACCEPT– Acceptable content types for the response.HTTP_ACCEPT_ENCODING– Acceptable encodings for the response.HTTP_ACCEPT_LANGUAGE– Acceptable languages for the response.HTTP_HOST– The HTTP Host header sent by the client.HTTP_REFERER– The referring page, if any.HTTP_USER_AGENT– The client’s user-agent string.QUERY_STRING– The query string, as a single (unparsed) string.REMOTE_ADDR– The IP address of the client.REMOTE_HOST– The hostname of the client.REMOTE_USER– The user authenticated by the Web server, if any.REQUEST_METHOD– A string such as"GET"or"POST".SERVER_NAME– The hostname of the server.SERVER_PORT– 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.
很多同學在找Content-Range的時候發現文檔中沒有這個，所以以爲不支持這個，一直再找。百度 Google什麼的
但是其實這個文檔只是列出的其中一部分，而且他們沒細心的讀A standard Python dictionary containing all available HTTP headers，這一句，同時上面的也只是一部分例子，因此在看文檔的時候，希望同學們能細心一點！
