我正在开发一个Android应用程序,我想在其中集成一个Facebook 发布功能。我下载了Facebook-Android SDK,然后 readme。Md(文本文件)在那里,其中提到要生成 Android的键散列。我如何生成它?

对于Android应用程序
这段代码用于在Android应用程序中获取Facebook集成的哈希键。我已经测试了所有的设备,一切正常。只更改此代码的包名:
private void facebookHashKey() {
try {
PackageInfo info = getPackageManager().getPackageInfo("com.app.helpcove", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String hashCode = Base64.encodeToString(md.digest(), Base64.DEFAULT);
System.out.println("Print the hashKey for Facebook :"+hashCode);
Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
}
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}
}
其他回答
Linux
开放式终端:
用于调试构建
keytool -exportcert -alias androiddebugkey -keystore debug.keystore | openssl sha1 -binary | openssl base64
你会发现debug。Keystore来自”。Android "文件夹复制并粘贴在桌面上,并运行上述命令
发布版本
keytool -exportcert -alias <aliasName> -keystore <keystoreFilePath> | openssl sha1 -binary | openssl base64
注意:确保在这两种情况下,它必须要求密码。如果它不要求输入密码,则意味着命令中有错误。
[EDIT 2020]->现在我完全推荐这里的答案,使用android studio更容易,更快,不需要写任何代码-下面这个是在eclipse时代的:)-。
您可以在任何活动中使用此代码。它将在logcat中记录hashkey,这是调试键。这很简单,而且比使用SSL轻松。
PackageInfo info;
try {
info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md;
md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String something = new String(Base64.encode(md.digest(), 0));
//String something = new String(Base64.encodeBytes(md.digest()));
Log.e("hash key", something);
}
} catch (NameNotFoundException e1) {
Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
Log.e("exception", e.toString());
}
你可以在知道密钥后删除代码;)
Kotlin代码获取哈希键
private fun logHashKey() {
try {
val info = getPackageManager().getPackageInfo("your.package.name", PackageManager.GET_SIGNING_CERTIFICATES);
for (signature in info.signingInfo.signingCertificateHistory) {
val md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
val something = Base64.getEncoder().encodeToString(md.digest());
Log.e("hash key", something);
}
} catch (e1: PackageManager.NameNotFoundException) {
Log.e("name not found", e1.toString());
} catch (e: NoSuchAlgorithmException) {
Log.e("no such an algorithm", e.toString());
} catch (e: Exception) {
Log.e("exception", e.toString());
}
}
请不要忘记在调试和发布环境中生成键,因为它们会随着构建设置而变化。
facebook开发者网站上的官方文件:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Add code to print out the key hash
try {
PackageInfo info = getPackageManager().getPackageInfo(
"com.facebook.samples.hellofacebook",
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) {
}
以下是步骤
Download openssl from Google code (If you have a 64 bit machine you must download openssl-0.9.8e X64 not the latest version) Extract it. create a folder- OpenSSL in C:/ and copy the extracted code here. detect debug.keystore file path. If u didn't find, then do a search in C:/ and use the Path in the command in next step. detect your keytool.exe path and go to that dir/ in command prompt and run this command in 1 line- $ keytool -exportcert -alias androiddebugkey -keystore "C:\Documents and Settings\Administrator.android\debug.keystore" | "C:\OpenSSL\bin\openssl" sha1 -binary |"C:\OpenSSL\bin\openssl" base64 it will ask for password, put android that's all. u will get a key-hash
