我正在尝试使用twitter4j库为我的java项目发送推文.在我第一次运行时,我收到了关于证书sun.security.validator.ValidatorException和错误的错误sun.security.provider.certpath.SunCertPathBuilderException.然后我添加了twitter证书:

C:\Program Files\Java\jdk1.7.0_45\jre\lib\security>keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore "C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts"

但没有成功.这是获得twitters的过程:

public static void main(String[] args) throws TwitterException {
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
        .setOAuthConsumerKey("myConsumerKey")
        .setOAuthConsumerSecret("myConsumerSecret")
        .setOAuthAccessToken("myAccessToken")
        .setOAuthAccessTokenSecret("myAccessTokenSecret");

    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();

    try {
        Query query = new Query("iphone");
        QueryResult result;
        result = twitter.search(query);
        System.out.println("Total amount of tweets: " + result.getTweets().size());
        List<Status> tweets = result.getTweets();

        for (Status tweet : tweets) {
            System.out.println("@" + tweet.getUser().getScreenName() + " …

我在Ubuntu 12.10上使用OpenSSL 1.0.1c,python 2.7.3,请求 1.0.3和1.0.4(尝试过两者),并尝试使用以下代码连接到url变量中的网站.

def SendInitialRequest(xmlmessage, redirecturl):
    url = 'https://centineltest.cardinalcommerce.com/maps/txns.asp'

    payload = 'cmpi_msg=' + ET.tostring(xmlmessage)
    headers = {
        'Content-Type': 'application/x-www-form-urlencoded',
    }
    r = requests.post(url, data=payload, headers=headers, verify=None)
    print r.text

它会引发以下错误:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "clams/libs/centinel/thinclient.py", line 134, in SendInitialRequest
    r = requests.post(url, data=payload, headers=headers, verify=None)
  File "/home/jasonamyers/.virtualenv/clams/lib/python2.7/site-packages/requests/api.py", line 87, in post
    return request('post', url, data=data, **kwargs)
  File "/home/jasonamyers/.virtualenv/clams/lib/python2.7/site-packages/requests/api.py", line 44, in request
    return session.request(method=method, url=url, **kwargs)
  File "/home/jasonamyers/.virtualenv/clams/lib/python2.7/site-packages/requests/sessions.py", line 269, …

我需要通过HTTPS协议发出请求.我写了以下代码:

import java.net.HttpURLConnection;
import java.net.URL;

import org.junit.Test;

public class XMLHandlerTest {
    private static final String URL = "https://ancine.band.com.br/xml/pgrt1_dta_20150303.xml";

    @Test
    public void testRetrieveSchedule() {
        try {
            HttpURLConnection connection = (HttpURLConnection) new URL(URL).openConnection();
            connection.setRequestMethod("HEAD");
            int responseCode = connection.getResponseCode();
            System.out.println(responseCode);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

我得到了一个带有java.io.EOFException的异常堆栈跟踪:

我已经用尽了我的能力来研究和试验解决这个问题.我已经尝试过Trust Managers,ssl socket工厂,hostName验证器,scheme注册表,ssl上下文修改等.

有人可以帮帮我吗？

该计划是:
