    data = urllib.parse.urlencode(data_form).encode(encoding='utf-8')
    req = urllib.request.Request(query, data=data)
    res = urllib.request.urlopen(req, timeout=10)
   # result = res.read().decode('utf-8')
    print("已发布成功")

看运行结果是打印成功了，但是看实际网站后台mbigpic的值只传递了个[符号。我传递的mbigpic值是一个list，包含多值，希望表单提交多个 mbigpic[]同名表单，每个表单值对应一个传递的 mbigpic值，不知道这种情况传递多个同名表单值改咋搞？头大了

表单是key-value传值，key，value 都是字符串。想传数组value，把数组值自己编码，如json，或者逗号分隔的字符串，变成一个value传送。 key-value 不允许key重复
