我知道这里有很多这样的问题,但它们都没有为我工作:(
在我的Android应用程序中,我试图从URL获取Drawable / Bitmap,其发生方式如下:
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;
}
然而,每次我推出这个婴儿时,都会发生无法预料的事情:
java.io.FileNotFoundException: http://domain.com/profile/image
因为它可能对你有帮助,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 :)
如何解决这个问题?
捕获从手机到网络的流量我看到了这一点,这有点明显:) - 但我不知道如何做到正确:
GET /profile/image HTTP/1.1
Authorization: Basic BASICAUTHSTRING
User-Agent: Dalvik/1.4.0 (Linux; U; Android 2.3.7; Nexus One Build/GRK39F)
Host: domain.com

这是什么样的巫术?使用curl并使用设备上的EXACT SAME Header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
我马上得到了图像:&lt;
这里发生了什么?
答案 0 :(得分:5)
最后我开始工作了。
我希望BASICAUTHSTRING是正确的 - 好吧,我有点不对劲。
android.util.Base64.encodeToString(authString.getBytes(), android.util.Base64.DEFAULT)
会在最后附加一个新行。所以请使用
android.util.Base64.No_WRAP
标记。
所以所有的麻烦都只是一个字节:)
