當手動運行vs編程時，我得到了來自同一命令的兩個不同輸出，我不明白爲什麼。PowerShell輸出在手動和程序化執行之間有所不同
問題::命令powershell -Command "Get-Module -ListAvailable"
當在命令提示符下手動運行，我得到這個輸出::
U:\>powershell -Command "Get-Module -ListAvailable"

編程運行i的輸出s缺少「版本」列，並且只是可用模塊的一個子集。
我想也許不知何故，我調用了兩個不同的PowerShell可執行文件，所以我手動和編程運行powershell -Command "$PSVersionTable"。
從powershell -Command "$PSVersionTable"手動運行::
Name Value
---- -----
PSVersion 5.0.10586.117
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
BuildVersion 10.0.10586.117
CLRVersion 4.0.30319.18444
WSManStackVersion 3.0
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
從powershell -Command "$PSVersionTable"的綱領性運行::
Name Value
---- -----
PSVersion 5.0.10586.117
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...}
BuildVersion 10.0.10586.117
CLRVersion 4.0.30319.18444
WSManStackVersion 3.0
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
所以我覺得我運行的輸出輸出相同的PowerShell可執行文件。
任何人有什麼想法，爲什麼我運行相同的命令時，我得到2完全不同的輸出？
UPDATE :: 在@EBGreen的要求下，我包含了用於以編程方式運行命令的實際Java代碼。
public class Example {
private void myMethod(String command) throws IOException {
Process process = Runtime.getRuntime().exec(command);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
String output = "";
String line;
while((line = bufferedReader.readLine()) != null){
output += (line + "\n");
}
System.out.println((output.isEmpty() ? "No output was received!!!" : output));
BufferedReader errorBufferedReader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
String errorOutput = "";
while((line = errorBufferedReader.readLine()) != null){
errorOutput += (line + "\n");
}
System.out.println((errorOutput.isEmpty() ? "Nothing in the error output stream." : errorOutput));
}
public static void main(String[] args) throws IOException {
new Example().myMethod("powershell -Command \"Get-Module -ListAvailable\"");
}
}
您以編程方式運行時使用的實際代碼是什麼。命令是否在相同的用戶環境中運行？是一個64位和另一個32位？ – EBGreen
@EBGreen我會在一秒內發佈一個包含代碼的問題更新。 – Chiefwarpaint
@EBGreen代碼現已包含在帖子中。程序化執行是通過IntelliJ中的32位JDK完成的。手動執行通過cmd提示符（'C：\ Windows \ system32 \ cmd.exe'）完成。主機操作系統是64位Win 7. – Chiefwarpaint
