PostMethod提交302錯誤
301，302 都是HTTP狀態的編碼，都代表著某個URL發生了轉移，不同之處在於：
301 redirect: 301 代表永久性轉移(Permanently Moved)。
302 redirect: 302 代表暫時性轉移(Temporarily Moved )。
這是很官方的說法，那麼它們的區別到底是什麼呢？
這裏隻說解決方法，不針對這2個狀態進行詳解。

responseBody = getPostResponse(location, parts);// 用跳轉後的頁麵重新請求。
}
} else if (statusCode == HttpStatus.SC_OK) {
