我想用java登錄到一個網站,然後最終檢索cookie以訪問網站上的信息。看來我的職務要求是工作,但我收到的500的響應代碼,我想知道,這是因爲我格式化後的數據不正確發送郵寄請求到網站
當使用它說,後的格式爲下面的網站
{userName: "dfh", password: "suyj"}
在我的代碼,我就在想,這可能是問題用這個
String urlParameters = "userName:dfh,Password:suyj";
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
我是不是,如果是的話我怎麼能糾正我的帖子的數據格式?
下面是我的全部代碼

通常,表單參數被url編碼到POST正文中,如「name1 = value1&name2 = value2」。您可以使用Chrome開發人員工具/ firebug/etc下的網絡標籤查看發送的內容。 – Michelle
我用那個水龍頭找到{userName:「dfh」,密碼:「suyj」}我應該在看別的東西 – user1261404
