【问题描述】：
我想从 ms exchange 阅读我的电子邮件，我正在使用来自这里 http://code.google.com/p/javamail-android/ 的 java mail api，并且我已经成功地从我的 google 帐户中提取了电子邮件...exchange 的问题是我在本地拥有它并且我没有公共证书，android给我03-07 13:12:25.708: WARN/System.err(3886): javax.mail.MessagingException: Not trusted server certificate;
如何通过证书检查？
我从这里看到了 Vynayak 的例子：Sending Email in Android using JavaMail API without using the default/built-in app
他使用了一些 TrustManager 类，我也尝试过这样做，但我不知道如何将 trustFactory 类链接到 imap 属性。
到目前为止，我的活动中有这个：
Properties props = new Properties();
props.setProperty("mail.store.protocol", "imaps");
props.setProperty("mail.store.socketFactory.class",
"com.imap.DummySSLSocketFactory");
// Prevents to fall into NOT-secure connection
props.setProperty("mail.pop3.socketFactory.fallback", "false");
try {
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("imaps");
store.connect("mail.domain.com", "user", "pass");
System.out.println(store);
Folder inbox = store.getFolder("Inbox");
inbox.open(Folder.READ_ONLY);
Message messages[] = inbox.getMessages();
for (Message message : messages) {
System.out.println(message);
}
} catch (NoSuchProviderException e) {
e.printStackTrace();
System.exit(1);
} catch (MessagingException e) {
e.printStackTrace();
System.exit(2);
}
这里我知道props.setProperty("mail.store.socketFactory.class",
"com.imap.DummySSLSocketFactory");这行没有正确实现，因为我不知道如何在imaps中使用它..
还有 DummyTrustManager：
package com.imap;
import javax.net.ssl.X509TrustManager;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
public class DummyTrustManager implements X509TrustManager {
public void checkClientTrusted(X509Certificate[] cert, String authType) throws CertificateException {
// everything is trusted
}
public void checkServerTrusted(X509Certificate[] cert, String authType) throws CertificateException {
// everything is trusted
}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
}
还有 DummySoketSSLFactory：
package com.imap;
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
import javax.net.SocketFactory;
import javax.net.ssl.*;
public class DummySSLSocketFactory extends SSLSocketFactory {
private SSLSocketFactory factory;
public DummySSLSocketFactory() {
try {
SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(null,
new TrustManager[] { new DummyTrustManager() },
null);
factory = (SSLSocketFactory)sslcontext.getSocketFactory();
} catch(Exception ex) {
}
}
public static SocketFactory getDefault() {
return new DummySSLSocketFactory();
}
public Socket createSocket() throws IOException {
return factory.createSocket();
}
public Socket createSocket(Socket socket, String s, int i, boolean flag)
throws IOException {
return factory.createSocket(socket, s, i, flag);
}
public Socket createSocket(InetAddress inaddr, int i,
InetAddress inaddr1, int j) throws IOException {
return factory.createSocket(inaddr, i, inaddr1, j);
}
public Socket createSocket(InetAddress inaddr, int i)
throws IOException {
return factory.createSocket(inaddr, i);
}
public Socket createSocket(String s, int i, InetAddress inaddr, int j)
throws IOException {
return factory.createSocket(s, i, inaddr, j);
}
public Socket createSocket(String s, int i) throws IOException {
return factory.createSocket(s, i);
}
public String[] getDefaultCipherSuites() {
return factory.getDefaultCipherSuites();
}
public String[] getSupportedCipherSuites() {
return factory.getSupportedCipherSuites();
}
}

你能告诉我你是如何将邮件从你的谷歌帐户导入到应用程序中的吗？
