使用HttpResponse抛出错误下载文件作为大文件的"body size is too long"(>5MB)

Question

我正在从 s3 存储桶中检索文件并将内容作为文件返回，如下所示：

s3 = boto3.resource("s3")     
object = s3.Object(bucket-name,s3_key)    
text = object.get()['Body']        
response = FileResponse(text)          
response['Content-Disposition'] = 'attachment;filename=sample.xls'          
return response 

但是我在返回文件时收到错误"body size is too long"。

Answer 1

尝试：

from django.core.servers.basehttp import FileWrapper
from django.http import FileResponse
s3 = boto3.resource("s3")     
object = s3.Object(bucket-name,s3_key)    
text = object.get()['Body']        
FileResponse(FileWrapper(file(filename, 'rb')), content_type='application/x-zip-compressed')
response['Content-Disposition'] = 'attachment; filename=sample.xls'          
return response

这将对您有所帮助。
