django返回文件(无论什么格式的)给前端
读取文件方法:
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
def read_file(file_name, chunk_size=512): with open(file_name, "rb") as f: while True: c = f.read(chunk_size) if c: yield c else: break
from django.http import StreamingHttpResponse
from django.utils.encoding import escape_uri_path
file_name = f"{platform_cn}成本数据.xlsx"
response = StreamingHttpResponse(read_file(file_path))
response["Content-Type"] = "application/octet-stream" # 这里就写这个就可以,如果错了你去看中文乱码就会格式不对
response["Content-Disposition"] = f"'attachment; filename={escape_uri_path(file_name)}" # 文件名称是中文,防止中文乱码
response["Access-Control-Expose-Headers"] = "Content-Disposition" # 为了使前端获取到Content-Disposition属性
再给你们带一张图吧
