我想用java登录到一个网站,然后最终检索cookie以访问网站上的信息。看来我的职务要求是工作,但我收到的500的响应代码,我想知道,这是因为我格式化后的数据不正确发送邮寄请求到网站
当使用它说,后的格式为下面的网站
{userName: "dfh", password: "suyj"}
在我的代码,我就在想,这可能是问题用这个
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,如果是的话我怎么能纠正我的帖子的数据格式?
下面是我的全部代码

通常,表单参数被url编码到POST正文中,如“name1 = value1&name2 = value2”。您可以使用Chrome开发人员工具/ firebug/etc下的网络标签查看发送的内容。 – Michelle
我用那个水龙头找到{userName:“dfh”,密码:“suyj”}我应该在看别的东西 – user1261404
