我想通过 java 程序登录到ORKUT 。我正在使用以下程序来做到这一点。我是从某个网站复制的。现在我想将它用于ORKUT。但是我对某些行有一些疑问。
Q1。在哪里提供登录页面的 URL(我认为在新的 HTTPGET(".....") 中)?我是对还是错?
Q2。将什么参数传递给 HTTPPost("") 的构造函数。如果我们必须在登录网页的html源中传递“form”元素的“action”属性的值,那么请确认。
Q3。ORKUT 登录页面的“form”元素具有属性
onsubmit="return(gaia_onLoginSubmit());"
由于上述属性的存在,我是否需要对以下代码进行任何更改?
Q4。登录后如何获取网页的html源?
