我正在这里阅读Facebook开发者的开发指南
它说，我必须使用keytool导出签名为我的应用程序，如:
keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
我不知道如何找到关键工具，以运行它。我试图打开Windows命令提示符并粘贴上述命令，但它不起作用。

Robby Pond的回答可以概括为使用JAVA_HOME环境变量，并补偿路径中可能出现的任何空白(如Program Files):
"%JAVA_HOME%\bin\keytool" -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
其他回答
KeyTool是JDK的一部分。假设您使用默认设置安装了JDK，您将在$JAVA_HOME/bin中找到它
在我的例子中，我已经使用ionic cordova build android——prod命令生成了一个APK文件，我需要为已经存在的APK文件获取SHA-1指纹。下面是我如何通过在App目录中运行以下命令来获得它:
Keytool -list -printcert -jarfile app-debug.apk
所以，我基本上在以下应用程序位置运行上述命令:
C:\myApp\platforms\android\app\build\outputs\apk\debug>keytool -list -printcert -jarfile app-debug.apk
这给了我SHA1指纹为:7B:6B:AD:…
希望这能帮助到一些人!
如果你安装了带有Xamarin/移动开发支持的visual studio，你将在这里安装java C:\Program Files\Android\jdk\ microsoft_dist_openjdk_{version}\bin\，就像我的情况一样。

Few observations while I was getting the same problem (Windows). 1. Shell pipe is important. 2. If you are using OpenSSL or Cygwin, definitely you have to install it. 3. keytool comes with JDK so either you have to point to it in the command or you have cd to the JDK/bin folder (where the exe resides) 4. The debug keystore is typically located at ~/.android/debug.keystore 5. password is "android" whether you -keypass it or type it when prompted. 6. For the alias name, you can open (DO NOT SAVE, just open and close) the keystore file with any editor and read it. 7. MOST IMPORTANT - There is a difference is specifying the keystore path within quotes and without. I got it working by using the keystore path within the double quotes. As remix090378 said and as per the instruction, this command indeed worked - cd C:\Program Files\Java\jdk1.7.0_09\bin
keytool -exportcert -alias androiddebugkey -keystore "C:\Users\userName.android\debug. keystore "密钥存储库" -list -v
