其實登錄支付寶的方式有很多種
最簡單的就是搞清楚支付寶的
3DES加密方式
直接在主頁登錄
這邊當然講的就是如何繞過支付寶加密
然後登入到支付寶內拉

方式有很多種
這裏先講下淘寶接口好了
衆所周知
登入淘寶帳號之後
在我的淘寶中是有支付寶的跳轉接口的
還有就是淘寶的登錄並不一定需要加密
僞裝成Linux+Chrome客戶端的話
只需要提供 帳號 密碼 驗證碼
即可登入淘寶系統

以下是實現code

	public static void main(String[] args) throws Exception {
		
		//獲取checkcode
		HttpGet get = new HttpGet("https://login.taobao.com/member/login.jhtml");
		HttpClient http = new DefaultHttpClient();  
		http.getParams().setParameter(ClientPNames.COOKIE_POLICY,CookiePolicy.BEST_MATCH);
		
		HttpResponse response = http.execute(get);
		if (response.getStatusLine().getStatusCode() == 200) {
			List<Cookie> cookies = ((AbstractHttpClient) http).getCookieStore().getCookies();
		    for (int i = 0; i < cookies.size(); i++) {
		    	if(cookies.get(i).getName().contains("cookie2"))
		    		System.out.println("checkcode url:\nhttps://regcheckcode.taobao.com/auction/checkcode?sessionID="+cookies.get(i).getValue());
		    }
		}
		//釋放連接
		get.abort();
		//手動輸入checkcode
		System.out.println("input checkcode:");
		Scanner scan=new Scanner(System.in);
		String checkcode=scan.nextLine().trim();
		
		String tbcUsername="<username>";
		String tbcPassword="<password>";
		
		//登入環境設置爲Chrom+Linux 不會有控件加密
