Form data 数据项中有几项是可变的，甲鱼讲的例子中用的是以前的版本，所有项都是不变的，哪位大神能回答下可变项怎么处理吗？感谢！！！

• i:
  horse
  
• from:
  AUTO
  
• to:
  AUTO
  
• smartresult:
  dict
  
• client:
  fanyideskweb
  
• salt:
  15811300544545  （可变）
  
• sign:
  1995f9d89925f2942ea34e5edb1f5c21  
  （可变）
• ts:
  1581130054454  
  （可变）
• bv:
  b396e111b686137a6ec711ea651ad37c
  
• doctype:
  json
  
• version:
  2.1
  
• keyfrom:
  fanyi.web
  
• action:
  FY_BY_REALTlME
  
  

代码结构跟访问iciba的其实是一样的，但是访问iciba可以得到有效返回，访问有道时就返回{'errorCode': 50}，没有得到想要的结果。不知道怎么回事？？？

只用写 i、to、smartresult、doctype、version、keyfrom、action 就可以了。
