python实现文件上传--python服务端部分

python服务端部分：

# URL: /api/attach/upload 
# 上传附件 
class ApiAttachUploadHandler(BaseHandler): 
    @login_required('teacher') 
    def post(self): 

        upload_dir = os.path.realpath(os.path.join(
            os.path.dirname(__file__),"../static/uploads/attach")) 
        random_name = str(uuid.uuid4()) 
        # input 名字一定是"fileupload" 
        file_data = self.request.files["fileupload"][0] 
        original_name = file_data['filename'] 
        extension = os.path.splitext(original_name)[1].lower() 
        final_name = random_name + extension 
        final_path = os.path.join(upload_dir,final_name) 
        file_length = len(file_data['body']) 
        output_file = open(final_path, 'wb') 
        output_file.write(file_data['body']) 
        output_file.close() 
        result = {'fpath':final_path, 'oname':original_name, 'ext':extension} 
        self.write({'code':'ok', 'result':result})
