When I use requests lib in Python, there are some cases in which I cannot get 'Content-Length' in headers with 'Transfer-Encoding': 'chunked'.

Firstly I tried requests.get(image_url), there is no 'Content-Length' in headers. Then I tried requests.head(image_url), there is 'Content-Length' in headers.

Is there any requests's method to combine both of get and head method? I mean if get method does not work, then try head method.

it is called `if/else`. OR use always `head` if you need only `'Content-Length'` – furas Jun 21 '20 at 09:45

HTTP says that chunked shouldn’t have a content-length header, so why don’t you simply always do a head, then you know the content length. – DisappointedByUnaccountableMod Jun 21 '20 at 09:45
Because in some cases, `head` method does not work, while the `get` method work. – quyleanh Jun 21 '20 at 10:30

then simply use `if/else` – furas Jun 21 '20 at 11:33
@furas I have already use `if/else` but I just wonder is there any method. Moreover, if there is any server decides to hide the `Content-Length`, how do I get it? – quyleanh Jun 21 '20 at 16:06
