【问题描述】：
我正在尝试使用 Dropbox Java API 让我的 Java 应用程序上传文件。不知何故，我最终遇到了我无法解决的相同 SSL 错误。有什么建议吗？
我使用了这段代码 (http://aaka.sh/patel/2011/12/20/authenticating-dropbox-java-api/)
public class DropboxTest {
// App key & secret that Dropbox's developer website gives your app
private static final String APP_KEY = "myAppKey";
private static final String APP_SECRET = "myAppSecret";
// Define AccessType for DropboxAPI object
final static private AccessType ACCESS_TYPE = AccessType.APP_FOLDER;
private static DropboxAPI<WebAuthSession> mDBApi;
public static void main(String[] args) throws Exception{
// Initialize the goods/session
AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
WebAuthSession session = new WebAuthSession(appKeys, ACCESS_TYPE);
// Initialize DropboxAPI object
mDBApi = new DropboxAPI<WebAuthSession>(session);
// Get ready for user input
Scanner input = new Scanner(System.in);
// Open file that stores tokens, MUST exist as a blank file
File tokensFile = new File("TOKENS");
System.out.println("Enter 'a' to authenticate, or 't' to test reauthentication: ");
String command = input.next();
if(command.equals("a")){
try {
// Present user with URL to allow app access to Dropbox account on
System.out.println("Please go to this URL and hit \"Allow\": " + mDBApi.getSession().getAuthInfo().url);
AccessTokenPair tokenPair = mDBApi.getSession().getAccessTokenPair();
// Wait for user to Allow app in browser
System.out.println("Finished allowing? Enter 'next' if so: ");
if(input.next().equals("next")){
RequestTokenPair tokens = new RequestTokenPair(tokenPair.key, tokenPair.secret);
mDBApi.getSession().retrieveWebAccessToken(tokens);
PrintWriter tokenWriter = new PrintWriter(tokensFile);
tokenWriter.println(session.getAccessTokenPair().key);
tokenWriter.println(session.getAccessTokenPair().secret);
tokenWriter.close();
System.out.println("Authentication Successful!");
}
} catch (DropboxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else if(command.equals("t")){
Scanner tokenScanner = new Scanner(tokensFile); // Initiate Scanner to read tokens from TOKEN file
String ACCESS_TOKEN_KEY = tokenScanner.nextLine(); // Read key
String ACCESS_TOKEN_SECRET = tokenScanner.nextLine(); // Read secret
tokenScanner.close(); //Close Scanner
//Re-auth
AccessTokenPair reAuthTokens = new AccessTokenPair(ACCESS_TOKEN_KEY, ACCESS_TOKEN_SECRET);
mDBApi.getSession().setAccessTokenPair(reAuthTokens);
System.out.println("Re-authentication Sucessful!");
//Run test command
System.out.println("Hello there, " + mDBApi.accountInfo().displayName);
}
}
}
以 SSL 异常结束：

【问题讨论】：
-
您使用的是什么版本的 Java？
-
1.7 但 1.6 给出了同样的错误
-
我刚刚去了dropbox.com/developers/reference/api，并提供了一个不受信任的 SSL 证书（我使用的是 Chrome 19），所以这很可能是同一个问题。
-
是的，这与 Dropbox 客户端无关（见根本原因），只是一个不受信任的证书
-
如何让我的客户端应用程序信任该证书？
