我可以使用什么来将脚本中的文件参数从 html 代码传递给 cherrypy 函数

Question

那么我该怎么做才能将参数传递给函数。

import os, random, string
import cherrypy


class StringGenerator(object):

    @cherrypy.expose        
    def index(self):        
      return """<!DOCTYPE html>

        '/static': {

    cherrypy.quickstart(StringGenerator(), '/', conf)

查看文件 cherrypy files tutorial，但要为您提供具体答案，您的 generate 方法必须使用 file1 的 file 属性参数.

例如，此方法可行：

@cherrypy.expose            
def generate(self, length, file1):            
    some_string = "harsh" + length        
    cherrypy.session['mystring'] = some_string        
    file_content = file1.file.read()
    return file_content

您还可以对 file 属性进行操作以获取更多信息，它是 python TemporaryFile.
