我浏览过其他一些关于以编程方式登录网站的帖子,但他们的解决方案并没有解决我的问题。我已经习惯了JAVA一段时间,所以我非常熟悉它,但这是我第一次写任何涉及https连接的东西。我正在尝试登录link2feed.ca并从网站上提取数据。但是,我一直遇到握手失败错误。我尝试了多种不同方式连接到网站的实现,但它们都会导致相同的错误。
这是我的代码:
URI LINK_2_FEED_LOGIN_URL = new URI("https://portal.link2feed.ca/login_check");
BasicCookieStore cookieStore = new BasicCookieStore();
CloseableHttpClient httpclient = HttpClients.custom()
.setDefaultCookieStore(cookieStore)
.build();
try {
HttpGet httpget = new HttpGet(LINK_2_FEED_LOGIN_URL);
CloseableHttpResponse response1 = httpclient.execute(httpget);
try {
HttpEntity entity = response1.getEntity();
System.out.println("Login form get: " + response1.getStatusLine());
EntityUtils.consume(entity);
System.out.println("Initial set of cookies:");
List<Cookie> cookies = cookieStore.getCookies();
if (cookies.isEmpty()) {
System.out.println("None");
} else {
for (int i = 0; i < cookies.size(); i++) {
System.out.println("- " + cookies.get(i).toString());
}
}
} finally {
response1.close();
}
HttpUriRequest login = RequestBuilder.post()
.setUri(LINK_2_FEED_LOGIN_URL)
.addParameter("login_email", USER)
.addParameter("login_password", PASSWORD)
.build();
CloseableHttpResponse response2 = httpclient.execute(login);
try {
HttpEntity entity = response2.getEntity();
System.out.println("Login form get: " + response2.getStatusLine());
EntityUtils.consume(entity);
System.out.println("Post logon cookies:");
List<Cookie> cookies = cookieStore.getCookies();
if (cookies.isEmpty()) {
System.out.println("None");
} else {
for (int i = 0; i < cookies.size(); i++) {
System.out.println("- " + cookies.get(i).toString());
}
}
} finally {
response2.close();
}
} finally {
httpclient.close();
}
以下是我收到的错误:

我觉得这是一个我很想念的非常简单的问题,但我无法确定它。非常感谢所提供的任何帮助。
