Dropbox Java:将代理与身份验证配合使用 [英] Dropbox Java: Use Proxy with authentication

问题描述

我想用StandardHttpRequestor创建我的DbxRequestConfig对象，因为我需要使用它来使用代理.

I want to create my DbxRequestConfig Object with a StandardHttpRequestor, because I need it to use a Proxy.

该代理是一个http代理，端口80，并且需要身份验证.

The Proxy is a http Proxy, Port 80, and needs authentication.

Proxyaddress:    http://myproxy.com
Proxyport:       80
Proxyusername:   username
Proxypassword:   password

所以我尝试使用全局Java代理设置:

So I tried to use the global Java Proxy setup:

System.setProperty("http.proxy","proxyaddress") //... http.proxyUser, http.ProxyPassword
//and so on

它没有用.

研究了StandardHttpRequestor之后，我意识到我需要同时使用该对象和Proyx对象:

After looking into the StandardHttpRequestor I realized I need to use this Object as well as a Proyx Object:

Proxy proxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress(ip,port));            
StandardHttpRequestor requ = new StandardHttpRequestor(proxy);

这是错误的，因为它没有身份验证.

Which is wrong, because it has no authentication.

对于身份验证，网络和Google向我显示了以下内容.综上所述，我当前的代码如下所示:

For authentication, the net and google show me the following. Putting all together, my current code looks like the following:

String ip = "http://myproxy.com";
int port = 80;

final String authUser = "username";
final String authPassword = "password";

Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
         return new PasswordAuthentication(authUser, authPassword.toCharArray());
    }
});

System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);

Proxy proxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress(ip,port));
StandardHttpRequestor requ = new StandardHttpRequestor(proxy);
return requ;

但是，这还不能正常工作.

But this does not work as well.

我做错了什么? 我似乎无法使代理正常工作.

What am I doing wrong? I can't seem to get the Proxy to work.

推荐答案

一个问题是String ip = "http://myproxy.com";

我当前的代码如下所示，并且有时可以工作.有时不是.我不知道为什么.有时我必须重新设置应用程序才能连接到我的DropBox帐户，因为authKey不会通过代理...

My current code looks the following, and works sometimes. Sometimes not. I have no idea why. Sometimes I have to reallow the App to be connected to my DropBox Account, because the authKey doesn't come through the proxy...

至少我有一个例子为遇到同样麻烦的你们工作.也许剩下的问题就在代理方面?我将对此进行进一步的研究.但是我的代码在这里:

Well at least I got an example working for you guys having the same trouble. Maybe the rest of the problem is on the proxy side? I'll have a further look into this. But here comes my code:

public HttpRequestor getProxy(){

    if("true".equals(config.getProperty("proxy","false"))){
        String ip = "proxy.myproxy.com";
        int port = 80;

        final String authUser = "username";
        final String authPassword = "password";

        Authenticator.setDefault(new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(authUser, authPassword.toCharArray());
            }
        });

        Proxy proxy = new Proxy(Proxy.Type.HTTP,new InetSocketAddress(ip,port));


        HttpRequestor req = new StandardHttpRequestor(proxy);
        return req;
    }
    return null;
}

如您所见，我不再使用StandardHttpRequestor.对于Dropbox代码，如下所示:

As you can see I don't use the StandardHttpRequestor anymore. For the Dropbox code it is the following:

HttpRequestor requ = con.getProxy();
if(requ!=null)
    config = new DbxRequestConfig(APP_NAME, Locale.getDefault().toString(),requ);
else
    config = new DbxRequestConfig(APP_NAME, Locale.getDefault().toString());

正如我已经说过的，有时它可以工作.有时不是.一旦知道是由于代码还是由于代理本身，我将立即编写有关此信息的更多信息.

As I already said, sometimes it works. Sometimes not. I'm going to write more info about that as soon as I know if it's because of the code or because of the proxy itself.
