Django休息框架ApiView重新编译可执行文件

Posted 2021-04-25

问题类似于这个django rest framework return file

尝试应用类似的解决方案在Django Rest ApiView中返回可执行的python二进制文件：

from wsgiref.util import FileWrapper

bin_file = open(f'cli/builds/dist/cli', 'rb')
response = Response(FileWrapper(bin_file), content_type='application/octet-stream')
response['Content-Disposition'] = f'attachment; filename="cli"'
response.status_code = status.HTTP_200_OK
return response

得到Object of type 'FileWrapper' is not JSON serializable错误。参考前面提到的SO主题 - 这个解决方案适用于zip文件。

问题 - 为什么它不能用于我的设置，返回python可执行文件？

python 3.6.5，djangorestframework==3.8.2

尝试过Response和HttpResponse课程

答案

尝试使用HttpResponse而不是DRF的Response，

from wsgiref.util import FileWrapper
from django.http.response import HttpResponse

bin_file = open(f'cli/builds/dist/cli', 'rb')
response = HttpResponse(FileWrapper(bin_file), content_type='application/octet-stream')
response['Content-Disposition'] = f'attachment; filename="cli"'
response.status_code = status.HTTP_200_OK
return response
