脸书发布key_hash

Question

我对生成密钥哈希有问题。我做了2把钥匙：

C:\openssl\bin>"C:\Program Files\Java\jre7\bin\keytool.exe" -exportcert -alias forumurology -keystore uroweb7228.keystore | openssl sha1 -binary | openssl base64
Enter keystore password:  *******
c/6e5fY8Rg3Gshn1TKucia***/A=

C:\openssl\bin>"C:\Program Files\Java\jre7\bin\keytool.exe" -exportcert -alias a
ndroiddebugkey -keystore debug.keystore | openssl sha1 -binary | openssl base64
Enter keystore password:  android

然后将其保存到我的facebook应用程序设置中。当我运行发布版.apk时，出现了错误：

10-21 16:48:11.583: W/fb4a(:<default>):BlueServiceQueue(20097): Exception during service
10-21 16:48:11.583: W/fb4a(:<default>):BlueServiceQueue(20097): com.facebook.http.protocol.ApiException: Key hash ypC1--aybTSQXdzXGLtM-_nXydI does not match any stored key hashes.

Answer 1

这是因为设备正在创建一个新的密钥哈希，它不在您的应用程序设置中。因此，您必须相应地更新密钥哈希。在onCreate()中使用这个

try {
            PackageInfo info = getPackageManager().getPackageInfo("YOUR_PACKAGE_NAME", PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }
