使用请求发布通过 openpyxl 修改的 excel 工作簿

Question

I have an excel sheet that I wrote on memory and that I want to modify using openpyxl. Due to several circumstances I cannot use temporary files or anything of the sort. I am also writing the original sheet not using openpyxl, but xlsxwriter, for reasons that I do not wish to elaborate upon. The original sheet is saved in a bytes-like format, however, so I am wondering if I can do the same with the modified excel sheet and then upload it using requests.

This is the code I am using:

def UploadXLS(name, xlsx):
   wb = opx.load_workbook(io.BytesIO(xlsx))     
   wb.security = WorkbookProtection(workbookPassword = 'super-secret-password', lockStructure = True)
   wb.save(name)

   r = requests.post('my-url-here', 
                      files = wb)
return r.url

And this is the (predictable) error message I am getting:

a bytes-like object is required, not 'Workbook'

Any help or advice on the topic would be much appreciated.

Answer 1

The problem here is that you are attempting to pass the openpyxl Workbook object to the post() request. However, post() does not know how to handle a Workbook . But it does know how to handle any generic file stream. So the solution is to open the file and pass the stream to the request:

file = open(name, 'r')
r = requests.post('url', files=file)
