我知道这里有很多这样的问题，但没有一个对我有用:(
在我的 Android 应用程序中，我试图从 URL 获取 Drawable/Bitmap，如下所示：
public Bitmap loadBitmap(ISettings settings) {
Bitmap bm = null;
InputStream is = null;
BufferedInputStream bis = null;
final URL imageURL = new URL("http://domain.com/profile/image");
final String authString = settings.getUserName() + ":" + settings.getPassword();
final String authStringEnc = Base64.encodeToString(authString.getBytes(), Base64.DEFAULT);
URLConnection conn = url.openConnection();
conn.setRequestProperty("Authorization", "Basic " + authStringEnc);
conn.connect();
is = conn.getInputStream();
bis = new BufferedInputStream(is, 8192);
bm = BitmapFactory.decodeStream(bis);
return bm;
}
但是，每次我启动这个婴儿时，都会发生一些意想不到的事情：
java.io.FileNotFoundException: http://domain.com/profile/image
因为它可能对您有所帮助，这里是资源的卷曲
curl -u Username:Password http://domain.com/profile/image
及其在wireshark中的输出：
GET /profile/image HTTP/1.1
Authorization: Basic BASICAUTHSTRING
User-Agent: curl/7.25.0 (i386-pc-win32) libcurl/7.25.0 OpenSSL/0.9.8u zlib/1.2.6 libidn/1.18 libssh2/1.4.0 librtmp/2.3

.. just the bytes of png which I cannot enter here as it would be too long :)
如何解决？
编辑＃1：
捕获从手机到网络的流量我看到了这一点，这有点明显:) - 但我不知道如何让它正确：

编辑#2：
这是什么巫术？使用 curl 并使用与设备上完全相同的标头信息：
curl -H "Connection: Keep-Alive" -H "Accept-Encoding: gzip" -H "Accept:" -H "User-Agent: curl/7.25.0 (i386-pc-win32) libcurl/7.25.0 OpenSSL/0.9.8u zlib/1.2.6 libidn/1.18 libssh2/1.4.0 librtmp/2.3" -u Username:Password http://domain.com/profile/image
