我在抢先身份验证方面遇到很多问题之后,终于让它工作了。 现在是下一个问题。我想用它来获取文件,但我不知道如何。 我认为文件数据可能在变量响应中,但事实并非如此。 任何想法如何可行?我正在尝试它,因为几天没有成功:( - 基本上我正在尝试下载一个jpeg文件,它位于受Prem。auth保护的服务器上。

答案 0 :(得分:3)
嗯,我现在自己解决了 - 这里是解决方案:
StringBuffer tmp = new StringBuffer(); // for content
if (entity != null) {
InputStream is = entity.getContent();
int l = 0;
byte[] t = new byte[1024];
while ((l = is.read(t)) != -1) {
for (int i=0; i<l ; i++){
tmp.append((char)t[i]);
}
}
}
return tmp.toString();
