获得HTTP 407错误作为一个IOException [英] Getting http 407 error as an IOException

问题描述

我用在我的Andr​​oid应用程序的 HttpURLConnection类通过在需要身份验证的代理。这里是我的code和我的问题后，我将解释。

I'm using in my android application the HttpURLConnection through a proxy where an authentication is needed. Here is my code and I will explain you after my problem.

HttpURLConnection connection = null;
int responseCode = -1;
try {
    connection = (HttpURLConnection) myUrl.openConnection();
    connection.setInstanceFollowRedirects(false);
    connection.setConnectTimeout(DEFAULT_TIMEOUT);
    connection.setReadTimeout(DEFAULT_TIMEOUT);

    responseCode = connection.getResponseCode();
    System.out.println("ResponseCode = " + responseCode);
} catch (IOException e) {
    System.out.println("Exception : " + e.getMessage());
}

我的问题是，我得到它具有以下消息GETRESPONSE code（）方法的一个例外：无法与代理验证。
通常情况下，此特定错误有一个HTTP错误code：407。但在这里我刚刚得到一个例外，但不响应code与407值

My problem is that I get an exception on the getResponseCode() method which has the following message : Failed to authenticate with proxy. Usually, this specific error has an http error code : 407. But here I just got an exception but not a response code with the 407 value.

我要申请的登录名和密码连接到代理服务器的解决方案，但我只想要的情况下适用该解决方案有一个407错误（而不是每次都让我赶上一个例外）。

I have the solution to apply the login and password to connect to the proxy, but I want to apply this solution only in the case there is a 407 error (and not each time I catch an exception).

任何想法将AP preciated。
谢谢你。

Any idea will be appreciated. Thanks.

推荐答案

尝试追赶的Htt presponseException 代替，并检查其状态code（ .getStatus code（）），看看它是否是407（或更好，但 HttpURLConnection.HTTP_PROXY_AUTH ，更具可读性）

Try catching HttpResponseException instead, and checking its status code (.getStatusCode()) to see if it's 407 (or better yet, HttpURLConnection.HTTP_PROXY_AUTH, more readable).

的Htt presponseException 是 IOException异常的一个子类，我认为这是一个的抛出的实际的异常

HttpResponseException is a subclass of IOException, and I think that's the actual exception that's being thrown.
