/**
* Function: Simulate Sina Weibo login
* Purpose: Simulate user login for subsequent operations, such as automatically controlling your Sina app to refresh certain data
* Note:
* 1. Need to install nodejs
* 2. If you need to download Sina’s encrypted js file, please go to the Sina login page to check the network and request to download the latest version yourself (I used: http://js.t.sinajs.cn/t35/miniblog/static/js/sso .js?version=e482ef2bbdaa8bc2)
* 3. Modify the Sina encrypted js file so that nodejs can run it
* 1) Add the following content in front of the file
var window = {
Location : {
Host : 'weibo.com',
Hostname : 'weibo.com',
href : 'http://weibo.com/',
Pathname : '/',
Port : '',
Protocol: 'http:',
Search : ''
},
Navigator : {
appCodeName         appName                                                                                                      appVersion BuildID : '20120713134347',
CookieEnabled : true,
doNotTrack : 'unspecified',
Language : 'en-US'
}
};
var location = window.location;
var navigator = window.navigator;
* 2) Add the following content at the end of the file
var argv = process.argv.splice(2);

var pubkey = argv[0],
Servertime = argv[1],
nonce = argv[2],
Password = argv[3];

var RSAKey = new sinaSSOEncoder.RSAKey();
RSAKey.setPublic(pubkey, '10001');
password = RSAKey.encrypt([servertime, nonce].join("t") + "n" + password);
console.log(password);
process.exit();
* 4. Modify the nodejs program path and the modified Sina js file path in the encode_password function
* 5. Change username and password
