httpx.post get a typing error when data is plain string

[szw0407]

Usually http post method sends data in JSON format, and the data in httpx.post is assigned to as typing.Optional[RequestData] type. However under some certain circumstances, some APIs require post data in other formats.

I used httpx.post to get data from an API, which requires a plain text in a certain format, but neither json nor xml, as the post body.

Yes, that is quite rare, and I suppose such APIs are badly designed. However, since content-type in header could be text\plain as well as other values, the RequestData type should not be simply Mapping[str, Any].

I get a typing error saying str is incompatible with RequestData when I write such codes:

import httpx

def example function(url:str, data_str:str):
    return httpx.post(url, data=data_str, header = {"Content-Type":"text/plain"})

Anyway, it works properly when I disable typing check. However, I wish the typing could be reconsidered.

I simply changed the line RequestData = Union[Mapping[str, Any], Sequence[Tuple[str, Any]], bytes, str, None], but I guess that is not proper. I wish it could be checked based upon the Content-Type value in the header.

Hi! I think the content argument is what you are searching for.

You can do something like this

httpx.post(url, content="my plain text", header = {"Content-Type":"text/plain"})
