python模拟登录博客园（附：问题求教）

经过分析，博客园登录时采用了JSEncrypt加密，因此登录请求时要用密文，涉及字段如下

input1：用户名对应的密文

input2：密码对应的密文

登录请求链接https://passport.cnblogs.com/user/signin

response = opener.open(

#返回信息{"Id":0,"IsSuccess":false,"Message":"无效的postId！","Data":null}    
print(response.read().decode("utf8"))

提交评论的链接为http://www.cnblogs.com/mvc/PostComment/Add.aspx

请求json如下

{"blogApp": "wujf",
"postId": 6475097,
"body": "xxxxxxxxxxxx",
"parentCommentId": 0
}

但是不知道为什么博客园会一直返回

{"Id":0,"IsSuccess":false,"Message":"无效的postId！","Data":null}

另：环境python3.5
