Question

我使用Djnago 1.10.4框架上传pdf，上传的文件返回django.core.files.uploadedfile.InMemoryUploadedFile的对象

当我尝试使用type（file_uploaded.file）从对象中提取数据时我正进入（状态宾语。现在使用file_uploaded.file.read（）。decode（'utf-8'）应该从pdf中提取数据。但我得到的是十六进制或某些东西的加密数据

if request.FILES:
    file_uploaded = request.FILES["file"]
    # file_uploaded = file.name
    print('file_uploaded')
    print(file_uploaded.file.read().decode('UTF-8', errors="ignore"))
    print("file_uploaded.file", type(file_uploaded.file))
    print("file_uploaded", type(file_uploaded))
    file_type = ""
    extn = file_uploaded.name
    file_supported = [".pdf", ".jpg", ".png",".json", ".rtf", ".docx", ".txt", ".csv"]
    extension = '.'+extn.split(".")[1]
    # extension = "." + .split(".")[1]
    if(extension in file_supported):
        for formates in file_supported:
            if (formates == extension):
                file_type = formates[1:]
    else:
         print ('file is not uploaded')

上面的代码适用于文本文件，如csv，rft但不适用于pdf。 pdf文件的输出是这个

以下是上传csv文件时终端的输出：

file_uploaded
3526 HIGH ST,SACRAMENTO,95838,CA,2,1,836,Residential
file_uploaded.file <class '_io.BytesIO'>
file_uploaded 
       <class'django.core.files.uploadedfile.InMemoryUploadedFile'>

请帮我解决这个问题。

使用django.core.files.uploadedfile.InMemoryUploadedFile从上传的pdf中提取数据返回编码数据
